Abstract:
Background: Anterior knee pain is a frequent condition after anterior cruciate ligament reconstruction (ACLR), but its origin remains uncertain. Studies have suggested that donor site morbidity in autologous bone–patellar tendon–bone reconstructions may contribute to patellofemoral pain, but this does not explain why hamstring tendon reconstructions may also present with anterior pain. Purpose: To evaluate the prevalence of anterior knee pain after ACLR and its predisposing factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated the records of all patients who underwent ACLR between 2000 and 2016 at a private facility. The prevalence of anterior knee pain after surgery was assessed, and possible risk factors (graft type, patient sex, surgical technique, range of motion) were evaluated. Results: The records of 438 patients (mean age, 30 years) who underwent ACLR were analyzed. Anterior knee pain was found in 6.2% of the patients. We found an increased prevalence of anterior knee pain with patellar tendon graft, with an odds ratio of 3.4 ( P = .011). Patients who experienced extension deficit in the postoperative period had an odds ratio of 5.3 of having anterior pain ( P < .001). Anterior knee pain was not correlated with patient sex or surgical technique. Conclusion: The chance of having anterior knee pain after ACLR was higher when patellar tendon autograft was used compared with hamstring tendon graft, as well as in patients who experienced extension deficit in the postoperative period.

Abstract:
ImportanceThe timing of surgery has been regarded as a key factor in anterior cruciate ligament reconstruction (ACLR), and early vs delayed ACLR remains a controversial topic.ObjectiveTo synthesize up-to-date published data from randomized clinical trials (RCTs) comparing early vs elective delayed ACLR for patients with ACL deficiency, in terms of clinical outcomes and complications.Data SourcesThe PubMed, Cochrane Library, and Web of Science databases were systematically searched until September 9, 2022.Study SelectionAll published RCTs comparing clinical and functional outcomes and complications associated with early ACLR vs elective delayed ACLR.Data Extraction and SynthesisTwo reviewers independently extracted relevant data and assessed the methodological quality following the PRISMA guidelines.Main Outcomes and MeasuresDue to the clinical heterogeneity, the random-effects model was preferred. The primary outcomes were functional outcomes and complications. The Mantel-Haenszel test was used to evaluate dichotomous variables and the inverse variance method was used to assess continuous variables.ResultsThis meta-analysis included 972 participants in 11 RCTs stratified by follow-up duration. The following factors did not differ between early and delayed ACLR: operative time (mean difference, 4.97; 95% CI, −0.68 to 10.61; P = .08), retear (OR, 1.52; 95% CI, 0.52-4.43; P = .44), and infection (OR, 3.80; 95% CI, 0.77-18.79; P = .10). There were also no differences between groups in range of motion, knee laxity, International Knee Documentation Committee (IKDC rating scale), and Tegner score. IKDC score (mean difference, 2.77; 95% CI, 1.89-3.66; P &amp;lt; .001), and Lysholm score at 2-year follow-up (mean difference, 2.61; 95% CI, 0.74-4.48; P = .006) significantly differed between early and delayed ACLR. In addition, the timing of surgery was redefined in the included RCTs and subgroup analyses were performed, which validated the robustness of the principal results.Conclusion and RelevanceThis systematic review and meta-analysis found that early ACLR was not superior to delayed ACLR in terms of most factors analyzed, except for IKDC and Lysholm scores. This information should be available to patients with ACL deficiency and clinicians as part of the shared decision-making process of treatment selection.

Abstract:
ABSTRACT The anterior cruciate ligament (ACL) is mostly responsible for providing knee stability. ACL injury has a marked effect on daily activities, causing pain, dysfunction, and elevated healthcare costs. ACL reconstruction (ACLR) is the standard treatment for this injury. However, despite good results, ACLR is associated with a significant rate of failure. In this context, the mechanical and biological causes must be considered. From a biological perspective, the ACLR depends on the osseointegration of the graft in the adjacent bone and the process of intra-articular ligamentization for good results. Here, we discuss the mechanisms underlying the normal graft healing process after ACLR and its biological modulation, thus, presenting novel strategies for biological enhancements of the ACL graft.

Abstract:
Anterior cruciate ligament reconstruction (ACLR) has become a popular surgery in orthopedic practice today, and the technique has evolved significantly over time. Surgical procedure, graft choice, and fixation systems have varied over the years. Nonetheless, several challenges like insufficient graft ligamentization, tunnel enlargement, and insufficient reestablishment of proprioception remain in ACLR. A vision of better graft healing and integration for improved outcomes after ACLR introduced the idea of the biological ACLR. Various techniques with growth factors, cellular therapies, or tissue augment have been researched with ACLR surgery for better integration and ligamentization. This review highlights the tissue wrappingmodalities currently being explored in biological ACLR.

Abstract:
Background: Reported rates of graft rupture and contralateral anterior cruciate ligament (ACL) rupture after ACL reconstruction (ACLR) are higher among pediatric patients than adults. Previous series may have underestimated postoperative event risk because of small sample sizes and high proportions of dropouts. Purpose: To calculate rates of graft rupture and contralateral ACL rupture after ACLR in a large pediatric series. Study Design: Case series; Level of evidence, 4. Methods: ACLRs performed in our tertiary care children’s hospital system over a period of >7 years were identified through billing review. Cases were sorted based on operative technique, with all-epiphyseal ACLRs considered separately. Transphyseal ACLRs were divided into 2 groups based on patient age, with a cutoff of 16 years. Clinic follow-up data as well as prospectively collected survey data were used to note graft rupture and contralateral ACL rupture events. Rates of graft rupture and contralateral ACL rupture were calculated using Kaplan-Meier survival analysis. Results: The final data set included 996 patients. A total of 161 patients underwent all-epiphyseal ACLR. Of the remaining transphyseal surgeries, 504 patients were <16 years of age at the time of surgery and 331 were ≥16 years. The 4-year cumulative rate of graft rupture via Kaplan-Meier survival analysis was 19.7% among all patients. The rate was 18.2% among all-epiphyseal ACLRs, 21.6% among transphyseal ACLRs in patients <16 years, and 16.4% among transphyseal ACLRs in patients ≥16 years ( P = .855). Survival analysis estimated the 4-year cumulative rate of contralateral ACL rupture at 12.0% among all patients: 6.63% among all-epiphyseal ACLRs, 15.7% among transphyseal ACLRs in patients <16 years, and 8.05% among transphyseal ACLRs in patients ≥16 years ( P = .093). Conclusion: This is the largest series of pediatric ACLRs yet reported, and it shows that the risks of another ACL injury after first-time ACLR are higher than previously reported. The risk of contralateral ACL rupture was lower than that for graft rupture. Our methods, including prospective follow-up surveys and survival analysis to generate cumulative rate estimates, provide a best-practice example for future case series calculations. Our results provide insight into the postoperative course of pediatric patients undergoing ACLR and are crucial for preoperative patient and family counseling. Understanding these risks may also influence return-to-play decisions.

Abstract:
Objectives: Anterior cruciate ligament (ACL) rupture is commonly associated with articular cartilage injury. Few studies have evaluated the influence of cartilage repair on the outcome of ACL reconstruction. Currently, no known study has examined the return to sport rates of concomitant ACL reconstruction and OCA. The purpose of this study is to evaluate rate and level of return to sports, as well as long-term outcomes, between a matched cohort of isolated ACL reconstruction (ACLR) versus ACL reconstruction with concomitant OCA (ACLR/OCA). Methods: A prospectively collected registry was queried retrospectively for consecutive patients who underwent ACL reconstruction with concomitant OCA. Inclusion criteria were preoperative diagnosis of ACL rupture and more than 2 years of follow-up. After meeting the inclusion criteria, all ACL reconstructions with concomitant OCA were matched to two isolated ACL reconstruction patients via +/- 5 years of age at time of surgery, gender, revision status, and ACL reconstruction graft type. At final follow-up, patients were asked to complete a subjective sports questionnaire, the Marx activity scale, a visual analog scale (VAS), and a satisfaction questionnaire. Results: Seventeen ACL/OCA patients met inclusion criteria. Fourteen eligible 2:1 matched pairs (28 ACLR; 14 ACLR/OCA;), were identified for analysis. The average age at the time of surgery was 33.89 +/- 8.64 and 35.92 +/- 6.22 for the ACLR and ACLR/OCA groups, respectively (P = .44). Average follow-up was 4.09 years and 5.14 years for the ACLR and ACLR/OCA groups, respectively (P = .17). At final follow-up, the average Marx activity scalescores were 6.54 for ACRL patients and 1.57 for ACLR/OCA patients; final scores were significantly different between groups (P < 0.01). The average VAS pain scores at final follow-up were 1.96 in the ACLR and 3.64 in ACLR/OCA groups with the ACLR/OCA patients displaying significantly worse final VAS pain scores (P = .03). 89.3% of ACLR patients (25 of 28) returned to at least 1 sport postoperatively compared with 57.1% of ACLR/OCA patients (8 of 14) (P=0.04). At final follow-up, 14.2% (2 of 14) of the ACLR/OCA group and 32.1% (9 of 28) of the ACLR group reported starting a new sport or activity. Average timing for full return to sports was 9.57 +/- 5.53 months and 9.27 +/- 3.25 months for the ACLR/OCA and ACLR groups, respectively (P = .86). At final follow-up, 33.3% and 57.1% of patients returned to better or same level of sport for the ACLR/OCA and ACLR groups, respectively (P = .06). Significantly more ACLR/OCA patients reported their activity level was hindered by their knee (92.8% ACLR/OCA; 60.7% ACLR). Significantly more ACLR patients reported satisfaction with their surgery compared with ACLR/OCA patients (89% vs 57%) (P < 0.01), however no statistical difference was observed in satisfaction with ability to play sports between groups. Conclusion: Significantly less ACLR/OCA patients (57.1%) were able to return to at least 1 sport when compared to a matched ACLR cohort (89.3%). At final follow-up, a higher percentage of ACLR patients were able to return to pretreatment activity intensity level or better (ACLR/OCA, 33.3%; ACLR, 57.1%). ACLR/OCA patients had significantly more pain and lower Marx activity scores. Despite a lower return to sport rate, there was no statistical difference in reported satisfaction with activity level between the groups, however the ACLR/OCA groups reported significantly lower overall surgical satisfaction.

Abstract:
The goal of an ACL reconstruction is to approximate the strength and characteristics of the native tissue. So, if the original ACL can rupture, it is logical to think that the reconstructed ligament can also tear. It is more difficult to deal with a revision case. Your decision what to do is dependent on what was done during the primary ACL reconstruction (ACLR). It is important to plan the surgery carefully and prepare for all possible scenarios intra-operatively. The three key questions you need to answer are the following? What was the GRAFT used? How were the TUNNELS made? What were the IMPLANTS used? It would be helpful to know who did the primary ACLR because you may be aware of some of the tendencies of that surgeon which may assist you in your surgery. There are seven situations that will be discussed: Bone-Patellar Tendon-Bone (BPTB) autograft using a trans-tibial technique Semitendinosus/Gracilis Tendon (ST/G) autograft using a trans-tibial technique With the advent of the medial portal technique, the position of the femoral tunnel changed dramatically. Five other circumstances arose from this: 3. ST/G autograft using endo-buttons 4. ST/G autograft using screws – femoral tunnel in ideal position 5. ST/G autograft using screws – femoral tunnel near where you want it to be 6. ST/G autograft using screws – femoral tunnel far from where you want it to be 7. Implant-less ACLR Always have a back-up plan when doing revisions. It is imperative that the rehabilitation program be delayed so as to give the graft more time to incorporate. Usually, twelve months before going back to sports is acceptable.

Abstract:
AbstractInfection following anterior cruciate ligament reconstruction (ACLR) is rare. Previous authors have concluded that diabetes, tobacco use, and previous knee surgery may influence infection rates following ACLR. The purpose of this study was to identify a cohort of patients undergoing ACLR and define (1) the incidence of infection after ACLR from a large multicenter database and (2) the risk factors for infection after ACLR. We identified patients undergoing elective ACLRs in the American College of Surgeons National Surgical Quality Improvement Program database between 2007 and 2013. The primary outcome was any surgical site infection within 30 days of surgery. We performed univariate and multivariate analyses comparing infected and noninfected cases to identify risk factors for infection. In total, 6,398 ACLRs were available for analysis of which 39 (0.61%) were diagnosed with a postoperative infection. Univariate analysis identified preoperative dyspnea, low hematocrit, operative time > 1 hour, and hospital admission following surgery as predictors of postoperative infection. Diabetes, tobacco use, age, and body mass index (BMI) were not associated with infection (p > 0.05). After multivariate analysis, the only independent predictor of postoperative infection was hospital admission following surgery (odds ratio, 2.67; 95% confidence interval, 1.02–6.96; p = 0.04). Hospital admission following surgery was associated with an increased incidence of infection in this large, multicenter cohort. Smoking, elevated BMI, and diabetes did not increase the risk infection in the present study. Surgeons should optimize outpatient operating systems and practices to aid in same-day discharges following ACLR.

Abstract:
ABSTRACT The anterior cruciate ligament (ACL) tear represents more than half of all knee injuries in sports that involve body rotations and sudden changes of direction. Discharging the athlete for return to play (RTP) post-ACL reconstruction (ACLR) is a difficult task with multidisciplinary responsibility. For many years, a six-month period post-ACLR was adopted as the only criterion for RTP. However, it is now suggested that RTP should not be exclusively time-based, but to clinical data and systematic assessments. Despite the importance of post-ACLR factors for RTP, pre- and peri-ACLR factors must also be considered. Historically, ACLR is performed with the hamstring or autologous patellar tendons, although the choice of graft is still an open and constantly evolving theme. Anterolateral ligament reconstruction and repair of meniscal ramp tear associated with ACLR have recently been suggested as strategies for improving knee joint stability. Subjective questionnaires are easy to apply, and help identify physical or psychological factors that can hamper RTP. Functional tests, such as hop tests and strength assessment by means of isokinetic dynamometers, are fundamental tools for decision making when associated with clinical evaluation and magnetic resonance imaging. Recently, the capacity to generate force explosively has been incorporated into the muscle strength assessment. This is quantified through the rate of torque development (RTD). Due to characteristics inherent to the practice of sport, there is an extremely short time available for produce strength. Thus, RTD seems to better represent athletic demands than the maximum strength assessment alone. This review investigates the pre-, peri- and post-ACLR factors established in the literature, and shares our clinical practice, which we consider to be best practice for RTP.

Abstract:
Background: The misuse of opioid medications has contributed to a significant national crisis affecting public health as well as patient morbidity and medical costs. After orthopaedic surgical procedures, patients may require prescription (Rx) opioid medication, which can fuel the opioid epidemic. Opioid Rx usage after anterior cruciate ligament reconstruction (ACLR) is not well characterized. Purpose: To determine baseline utilization of Rx opioids in patients undergoing ACLR and examine demographic, patient, and surgical factors associated with greater and prolonged postoperative opioid utilization. Study Design: Cohort study; Level of evidence, 3. Methods: Primary elective ACLRs were identified using Kaiser Permanente’s ACLR registry (2005-2015). We studied the association of perioperative risk factors on the number of dispensed opioid Rx in the early (0-90 days) and late (91-360 days) postoperative recovery periods using logistic regression. Results: Of 21,202 ACLRs, 25.5% used at least 1 opioid Rx in the 1-year preoperative period; 17.7% and 2.7% used ≥2 opioid Rx in the early and late recovery periods, respectively. Risk factors associated with greater opioid Rx in both the early and the late periods included the following: ≥2 preoperative opioid Rx, age ≥20 years, American Society of Anesthesiologists classification ≥3, other activity at the time of injury, chondroplasty, chronic pulmonary disease, and substance abuse. Risk factors associated with opioid Rx use during the early period only included the following: other race, acute injury, meniscal injury repair, multiligament injury, and dementia/psychosis. Risk factors associated with greater opioid Rx during the late period only included the following: 1 preoperative opioid Rx, female sex, body mass index ≥25 kg/m2, motor vehicle accident as the mechanism of injury, and hypertension. Conclusion: A quarter of ACLR patients had at least 1 opioid Rx before the procedure, but usage dropped to 2.7% toward the end of the postoperative year. We identified several perioperative risk factors for greater and prolonged opioid usage after ACLR.

Abstract:
Thesis Title: Enhancing rehabilitation following anterior cruciate ligament reconstruction. Context: Physical training with a neuromuscular focus has been shown to reduce anterior cruciate ligament (ACL) injury. However, ACL injury remains prevalent and often leads to joint instability, which requires surgical reconstruction. Following reconstructive surgery, a minimum of 6 months supervised rehabilitation is recommended with associated with financial cost implications to the National Health Service (NHS), the patient and society. Traditionally rehabilitation is offered in a concurrent format, whereby strength and cardio-vascular endurance exercises are performed in the same session. However, accumulating evidence from healthy populations, suggests that the development of strength might be attenuated by cardio-vascular endurance conditioning performed in close temporal proximity. This thesis comprises an entirely novel investigation of potential attenuation of strength gains in rehabilitating clinical populations that is associated with temporal incompatibility of physiological conditioning stimuli. No study has previously investigated this phenomenon, whether it might compromise the efficacy of treatment or recovery, or its potential influence on objectively-measured and patients’ perception of functional, musculoskeletal and neuromuscular performance capabilities. Objectives: The purpose of this thesis was to assess the effects of reconstruction surgery and 24 weeks of non-concurrent strength and endurance rehabilitation (with 48 week post-operative follow-up) on (a) subjective (IKDC; KOOS; PP [Chapter 4]) and objective measures of function (HOP [Chapter 5]) (primary outcome measures for this thesis), and (b) objective measures of musculoskeletal (ATFD) and neuromuscular performance (PF, EMD, RFD, SMP [Chapter 5]) (secondary outcome measures), in patients with anterior cruciate ligament deficiency. The secondary aim was to evaluate the relationships amongst a subjective outcome of function (IKDC), an objective outcome of function (HOP), and the secondary objective outcomes of musculoskeletal (ATFD) and neuromuscular (PF, RFD, EMD, SMP) performance at pre-surgery and at 24 weeks post-surgery (Chapter 6). Setting: Orthopaedic Hospital NHS Foundation Trust. Design: Prospective random-allocation to group trial involving iso-volume rehabilitative intervention versus contemporary practice, using contralateral limb assessment and clinico-social approbation controls. The design compared the effects of experimental post-surgical rehabilitation comprising non-concurrent strength and endurance conditioning with two conditions of control reflecting contemporary clinical practice (matched versus minimal assessment interaction). Participants: Eighty two patients (69♂, 13♀, age: 35.4 ± 8.6 yr; time from injury to surgery 9.4 ± 6.9 months [mean ± SD]) electing to undergo unilateral ACL reconstructive surgery (semitendinosus and gracilis graft [n = 57]; central third, bone-patella tendon-bone graft [n = 25]); were allocated to groups (2:2:1 purposive sampling ratio, respectively). Nineteen patients were lost to follow-up. Intervention: A standardised traditional concurrent (CON) ACL rehabilitation programme acted as the control versus an experimental non-concurrent (NCON) ACL rehabilitation programme that involved separation of strength and cardio-vascular endurance conditioning. An additional control group (Limited testing CON) matched the CON group rehabilitation applied within contemporary clinical practice. Outcome Measures: Chapter 4: The self-perceived primary outcome measures of function IKDC, KOOS and PP were assessed on five separate occasions (pre-surgery, and at 6, 12, 24 and 48 weeks post-surgery). However, assessment occasions were purposefully reduced to pre-operative and 48 weeks post-operative for the Limited testing CON group. Chapter 5: The primary objective outcome of function was HOP; the secondary outcomes were ATFD, PF, RFD, EMD and SMP associated with the knee extensors and flexors of the injured and non-injured legs. These objective outcomes were assessed on five separate occasions (pre-surgery, and at 6, 12, 24 and 48 weeks post-surgery). However, assessment occasions were purposefully reduced to pre-operative and at 48 weeks post-operative only for the Limited testing CON group. Chapter 6 Self-perceived (IKDC) subjective knee evaluation and the objective outcome of function (HOP), and selected objective outcomes of musculoskeletal and neuromuscular performance including ATFD, PF, RFD, EMD and SMP of the knee extensors and flexors of the injured and non-injured legs where applicable; measured at pre-surgery and at 24 weeks post-surgery were analysed for association, using Pearson product-moment correlation coefficients. A priori alpha levels were set at p<0.05. Results: Chapter 4: Factorial analyses of variance (ANOVAs) with repeated-measures investigating the primary aim showed significant group (NCON; CON) by test occasion (pre-surgery, 6, 12. 24 and 48 weeks post-surgery) interactions for self-perceived outcomes of function IKDC, KOOS and PP confirmed increased clinical effectiveness of NCON conditioning (F(2.0, 82.9)GG = 4.0 p<0.05, F(2.2, 134.7)GG = 5.5 p<0.001, F(1.9, 121.4)GG = 14.6 p<0.001, respectively) and the group mean peak relative difference in improvement for NCON was ~5.9% - 12.7% superior to CON. The greatest interaction effect was found to occur between pre-surgery and the 12 weeks post-operative test occasion for IKDC and KOOS, and between pre-surgery and the 24 week test occasion for PP. Patterns of improvements in self-perceived fitness over time were represented by a relative effect size range of 0.71 to 1.92. Improvement patterns were not significantly different between control groups offering matched or minimised assessor-patient interaction (CON vs. Limited testing CON; pre-surgery vs. 48 weeks post-surgery) indicating that clinical approbation by patients had not contributed to the outcome. Chapter 5: Factorial analyses of variance (ANOVAs) with repeated-measures showed significant group (NCON; CON) by leg (injured/non-injured) by test occasion (pre-surgery, 6, 12, 24 and 48 weeks post-surgery) interactions of the objective measure of function (HOP) together with the secondary outcomes of ATFD, PF, RFD, EMD and SMP. Similar responses were noted for the knee extensors and flexors of the injured and non-injured legs (F(2.1, 248) GG = 4.5 to 6.6; p<0.01) and confirmed increased clinical effectiveness of NCON conditioning (range ~4.7% - 15.3% [10.8%]) better than CON between 12 and 48 weeks. Patterns of improvements in physical fitness capabilities over time were represented by a relative effect size range of 1.92 to 2.89. Improvement patterns were not significantly different between control groups offering matched or minimised assessor-patient interaction (CON vs. Limited testing CON; pre-surgery versus 48 weeks post-surgery) indicating that clinical approbation by patients had not contributed to the outcome. Chapter 6: Two-tailed probabilities were used due to the exploratory nature of this study. A limited number of weak to moderate statistically significant correlations were confirmed (ranging from r = 0.262 – 0.404; p<0.05; n=48 [amalgamated NCON and CON groups] ) between IKDC and most notably, the neuromuscular performance outcome of EMD. Conclusion: Overall, the patterning and extent of changes amongst self-perceived, functional, musculoskeletal and neuromuscular performance scores offer support for the efficacy of using non-concurrent strength and endurance conditioning to enhance post-surgery rehabilitation. The limited robustness of relationships amongst the validated and frequently-used self-perceived outcome of function [IKDC], and objectively-measured outcomes of function and musculoskeletal and neuromuscular performance suggested that each might properly reflect an important but separate aspect of clinical response and should be deployed to detect change.

Abstract:
Les infeccions després de reconstrucció de lligament encreuat anterior (r-LLEA) són complicacions amb una incidència de entre 0,5% i 1.5% que poden arribar a ser greus si no es tracten de manera adequada. Durant la darrera dècada s’han publicat diversos estudis sobre la eficàcia i els resultats del desbridament artroscòpic d’aquestes infeccions. Malgrat això, la literatura sobre el seu origen i prevenció és més limitada així com el tractament antibiòtic adient de les mateixes. La present tesi es base en un compendi de tres publicacions sobre la etiologia, la prevenció i el tractament de les infeccions de r-LLEA. Els objectius són: avaluar la contaminació de les plàsties de lligament encreuat anterior (LLEA) com a origen de les infeccions; avaluar la efectivitat de una solució de vancomicina de 5mg/dl com a mètode per eradicar la contaminació i per tant disminuir la taxa d’infecció; i finalment avaluar la combinació de levofloxacino i rifampicina com a tractament antibiòtic òptim per a les infeccions estafilocòcciques. Durant l’obtenció i preparació de les plàsties de LLEA es va observar una taxa de contaminació d’un 14% la major part de la qual va ser deguda a estafilococs (71%). El remullat en una solució de vancomicina de 5mg/dl aconsegueix eradicar completament la contaminació. En la pràctica clínica, el remullat de les plàsties de LLEA en la solució de 5mg/dl de vancomicina redueix la taxa d’infecció de r-LLEA de 1,8% a 0%. Finalment, la combinació de levofloxacino i rifampicina orals (després de realitzar un desbridament artroscòpic) durant un període de 6 setmanes és un tractament efectiu per les infeccions estafilocòcciques. Les conclusions que s’han obtingut de la present tesi i el compendi de publicacions que la formen són: 1) Que la obtenció i preparació de les plàsties de LLEA és una font de contaminació bacteriana i podria ser l’origen de les infeccions de r-LLEA. 2) Que el remullat de les plàsties en una solució de 5mg/dl de vancomicina aconsegueix eradicar la contaminació i disminuir a 0% la taxa d’infeccions de r-LLEA. 3) Que el tractament amb levofloxacino i rifampicina associat al desbridament artroscòpic, és el tractament antibiòtic òptim per les infeccions estafilocòcciques després de r-LLEA.
Infections after anterior cruciate ligament reconstruction (ACL-R) are complications with an incidence between 0,5% and 1,5% and can cause serious knee joint damage if a correct treatment is not applied. During last decade several studies about arthroscopic debridement efficacy and outcomes have been published. However, literature about the origin and prevention of ACL-R infections is scarce same as its antibiotic treatment. The present thesis is a compendium of three publications about the etiology, the prevention and the treatment of infections after ACL-R. The purposes are: to evaluate the ACL graft contamination as a source of infection; to evaluate the effectiveness of a 5mg/dl vancomycin solution to eradicate contamination and thus reduce infection’s rate; and finally, to evaluate the combination of levofloxacin and rifampicin as the optimal antibiotic treatment for staphylococcal infections. A contamination rate of 14% was observed during ACL graft harvesting and preparation, most of it due to staphylococci (71%). The soaking in a 5mg/dl vancomycin solution completely eradicates contamination. In clinical practice the presoaking of ACL graft in the vancomycin solution reduces infection rate from 1,8% to 0%. Finally the combination of oral levofloxacin and rifampicin (along with arthroscopic debridement) for a period of 6 weeks is an effective treatment for staphylococcal infections. The conclusions of the present thesis and its publications compendium are: 1) The ACL graft harvesting and preparation is a source of contamination that can lead to infection. 2) The vancomycin solution of 5mg/dl completely eradicates the aforementioned contamination and reduces ACL-R infection rate to 0%. 3) The combination of levofloxacin and rifampicin after arthroscopic debridement is the optimal antibiotic schedule for staphylococcal ACL-R infections.

Abstract:
Anterior cruciate ligament injury leads to increased sagittal tibial translation, and perceptions of instability and low confidence in the knee joint are common. Many patients have remaining problems despite treatment and are forced to lower their activity level and prematurely end their career in sports. The effect of ACL reconstruction and/or rehabilitation on dynamic knee stability is not completely understood. The overall aim of this thesis was to study the dynamic knee stability during and after rehabilitation in individuals with ACL injury. More specific aims were 1) to elaborate an evaluation method for muscle strength, 2) to evaluate the effect of exercises in closed and open kinetic chain, and 3) to evaluate dynamic knee stability in patients with ACL deficiency or ACL reconstruction. Sagittal tibial translation and knee flexion angle were measured using the CA‐4000 computerised goniometer linkage. Muscle activation was registered with electromyography. The intra‐ and inter‐rater reliability of 1 repetition maximum (RM) of seated knee extension was clinically acceptable. The inter‐rater reliability of 1RM of squat was also acceptable, but the intra‐rater reliability was lower. The systematic procedure for the establishment of 1RM that was developed can be recommended for use in the clinic. One specific exercise session including cycling and a maximum number of knee extensions and heel raises did not influence static or dynamic sagittal tibial translation in uninjured individuals. A comprehensive rehabilitation program with isolated quadriceps training in OKC led to significantly greater isokinetic quadriceps strength compared to CKC rehabilitation in patients with ACL deficiency. Hamstring strength, static and dynamic translation, and functional outcome were similar between groups. Five weeks after ACL reconstruction, seated knee extension produced more anterior tibial translation compared to the straight leg raise and standing on one leg. All exercises produced less or equal amount of anterior tibial translation as the 90N Lachman test. Five weeks after the ACL reconstruction the static and dynamic tibial translation in the ACL reconstructed knee did not differ from the tibial translation on the uninjured leg. Patients in the early phase after ACL injury or ACL reconstruction used a joint stiffening strategy including a reduced peak knee extension angle during gait and increased hamstring activation during activity, which reduces the dynamic tibial translation. Patients with ACL deficiency that completed a four months rehabilitation program used a movement pattern that was more close to normal.

Abstract:
Injury to the anterior cruciate ligament (ACL) occurs 200,000 times per year in the United States. About half of these patients opt for ACL reconstruction (ACLr), while the other half choose non-surgical, conservative treatment. ACLr has been found to result in altered kinematics, namely external tibial rotation and knee adduction, during downhill running 1. ACLr also contributes to alterations in muscle activity after surgery. Leg muscles of the affected limb are weakened and contract in different muscle activation patterns when compared to healthy, uninjured patients 2.

Abstract:
Every year, approximately 80,000 to 150,000 ACL tears occur.[1,2] Post-injury, ACL reconstruction (ACLR) is often recommended to restore functional stability and prevent long-term joint degradation. However, while surgical techniques have improved, individuals with ACLR have been shown to have a higher risk of developing osteoarthritis (OA) and a higher rate of re-injury.[3] The higher incidence and earlier onset of knee OA in individuals who have undergone ACLR may be a result of a post-injury movement strategy that utilizes a higher degree of muscle co-contraction of the hamstrings and the quadriceps muscles during landing to increase joint stability.[4] This increased co-contraction leads to a “stiff” landing pattern, decreases shock absorption, and increases the ground reaction forces. These changes in lower extremity biomechanics also may result in higher forces which likely place the knee cartilage under greater stress and higher risk of OA development and re-injury.

Full text
Abstract:
Intercondylar notch impingement is detrimental to the anterior cruciate ligament (ACL). Notchplasty is a preventative remodeling procedure performed on the intercondylar notch during ACL reconstruction (ACLR). This study investigates how ACL graft geometry and both tibial and femoral insertion site location affect ACL-intercondylar notch interactions post ACLR. A range of ACL graft sizes are reported during ACLR, from 6mm–11mm in diameter. Minor variability of up to 3mm in ACL insertion site locations is reported during ACLR. Several 3D finite element (FE) knee joint models were constructed using three ACL graft sizes and polar arrays of tibial and femoral insertion site locations. Each knee model was subjected to flexion, tibial external rotation, and valgus motion. Impingement force and contact area between the ACL and the intercondylar notch compared well with published cadaver study results. A 3mm shift in the antero-lateral direction of the tibial insertion site of the average and maximum size ACL increased impingement force by 155.4% and 242.9% respectively. A 3mm shift in the anterior-proximal direction of the femoral insertion site of the average and maximum size ACL increased impingement by 292.6%, and 346.2% respectively. Simulated notchplasties of 4mm and 5mm reduced graft impingement force by 89.4% and 100% respectively for the simulations with greatest impingement. For the kinematics applied, the results show that small differences in graft size and insertion site location may lead to large increases in impingement force and contact area. The study aims to improve ACLR success rates by understanding how minor variations in graft size and insertion site location affect intercondylar notch impingement. Because minor variations in insertion site location during ACLR are a known occurrence, the results of this study may support the argument for performing notchplasty during ACLR.

The knowledge of in-vivo ACL forces is instrumental for understanding ACL injury mechanisms and for improving surgical ACL reconstruction techniques. Several in-vitro investigations have measured ACL forces in response to various loads applied to the knee. However, in-vivo ACL forces in response to controlled loading are still unknown. The objective of this study was to estimate the force of healthy ACL as well as the possible upper bound of ACL forces under an increasing axial tibial loading in living subjects using a non-invasive method.

Abstract:
The natural history of Anterior Cruciate rupture is one of progressive deterioration of knee function, with the development of instability, meniscal tears and post traumatic osteoarthritis. The current surgical approach is for anatomical reconstruction using a biological tissue autograft. It is well understood that the initial stability is dependent on the strength of the fixation rather than the strength of the graft, until the graft becomes biologically incorporated in the bone tunnel. A study was carried out to better understand postoperative internal bone stresses in anterior cruciate ligament (ACL) reconstruction surgery. The mechanical aspects of an interface screw fixation were examined both experimentally and numerically, with the aim to minimize deleterious effects in ACL reconstruction. The tibial cortical/cancellous bony tunnel and the stress pattern resulting from the screw fixation in the tunnel are investigated.

Abstract:
The quadrupled semitendinosus-gracilis (ST-G) graft is rapidly becoming the graft of choice for orthopaedic surgeons when reconstructing the anterior cruciate ligament (ACL). During this procedure orthopaedic surgeons harvest the distal semitendinosus and gracilis tendons and use them to replace the ruptured ACL. Although people who undergo this procedure have good functional outcomes over the short-term, we do not know the effect that harvesting these two tendons has on neuromuscular function. The purpose of this study was to examine the effect that ACL reconstruction with an autologous ST-G had on musculotendinous morphology. The methods used in the study included digital reconstruction of knee musculature from magnetic resonance images (MRI). Marked reductions in muscle volume, cross-sectional area, and length were observed in the semitendinosus and gracilis when reassessed approximately 6 months following surgery (after the subjects had returned to sports participation). The subjects appeared to compensate for the diminished medial knee flexor function with the biceps femoris (a lateral muscle) and semimembranosus muscles. These findings may have important implications for joint loading, the long term health of the knee, and surgical decision-making.
