Because of the role of the ACL in knee joint’s biomechanics, it is essential to quantify the kinematics of ACL deficient and ACL reconstructed knee. In-vitro models bare the handicap of limited muscle simulation, while static, one-dimensional testing cannot predict the behavior of these groups of patients under realistic loading conditions. Currently, the most widely accepted method for assessing joint movement patterns is gait analysis. Respectively, 3D motion analysis is necessary to provide high reliability movement analysis. The purpose of the study was in-vivo evaluation of the behavior of the anterior cruciate ligament deficient (ACLD) and anterior cruciate ligament reconstructed (ACLR) knees during walking, using 3D, real-time assessment tool. Significant alterations of joint kinematics in the ACLD knee were revealed in this study by manifesting a higher flexion gait strategy and excessive internal tibial rotation during walking that could result in a more rapid cartilage thinning throughout the knee. In the other hand, even though ACLR knees showed some improvements in sagittal plane compared to ACLD knees, in axial plane there still exists difference compared to healthy control knees. These kinematic changes could lead to abnormal loading in knee joint and initiate the process for future chondral degeneration. However, the post-operative kinematic data were collected 10 months after surgery, so a longer follow-up is needed to evaluate if these kinematic changes persist in time, and their effects in joint degeneration

Very little is known regarding the function of the posterior cruciate ligament in response to physiological loading conditions. A limited understanding of posterior cruciate ligament function might contribute to the poor clinical outcomes that are observed after reconstruction. Therefore, the objectives of this thesis were to quantify the biomechanical function of the posterior cruciate ligament both in-vitro and in-vivo and to investigate the effects of injury and reconstruction of the posterior cruciate ligament on knee joint biomechanics. First, muscle loading conditions were simulated in cadavers to measure the effects of posterior cruciate ligament injury and reconstruction on knee joint kinematics and contact pressures. Next, the structural properties of the grafts used in posterior cruciate ligament reconstructions were optimized using a theoretical model. In order to verify these results using an experimental model, an imaging system was developed to measure the strain distributions around the graft surface during tensile testing. Finally, the deformation of the posterior cruciate ligament was studied in living subjects using imaging and solid modeling techniques. Three-dimensional models of the knee joint, including the insertion sites of the posterior cruciate ligament were created from magnetic resonance images. The subjects then flexed their knees as they were imaged using fluoroscopy from two orthogonal directions. The models and orthogonal images were imported into a solid modeling software and used to reproduce the kinematics of the knee as a function of flexion. From these models, the three- dimensional deformation of the posterior cruciate ligament insertion sites was measured.
(cont.) These data illustrated that the in-vivo function of the posterior cruciate ligament is different from that observed in in-vitro studies. Current surgical treatments of posterior cruciate ligament injuries do not account for the in-vivo function observed in this study. In summary, this thesis quantified the biomechanical role of the posterior cruciate ligament in response to physiological loading conditions. In addition, grafts used to reconstruct the posterior cruciate ligament were optimized. These data provide valuable information for developing surgical treatments that recreate the in-vivo biomechanics of the posterior cruciate ligament.

Artroskopinė priekinio kryžminio raiščio rekonstrukcija – viena iš dažniausiai atliekamų ortopedinių operacijų. Adekvati skausmo kontrolė yra svarbi siekiant efektyvios ankstyvos reabilitacijos ir gerų funkcinių rezultatų, sutrumpinant gydymo ligoninėje trukmę. Atlikome randomizuotą perspektyvųjį dvigubai aklą placebu kontroliuojamą tyrimą panaudodami intrasąnarinius vaistus (morfiną ir neostigminą), derindami su vienkartine šlauninio nervo blokada. Taip pat tyrėme tęstinį skausmo malšinimą šlaunies perineuriniu kateteriu, taikydami du skirtingus paciento kontroliuojamos analgezijos režimus. Taikėme mažesnę vietinio anestetiko koncentraciją, siekdami selektyvesnės sensorinės blokados, mažesnės paros dozės, mažiau toksinių reakcijų. Tikrinome, ar tęstinis skausmo malšinimas yra veiksmingesnis nei vienkartinė nervo blokada su intrasąnarinėmis analgetikų injekcijomis. Intrasąnarinis morfinas turėjo panašų analgezinį poveikį kaip ir neostigminas paciento krūvio metu per visą tyrimo laiką (48 val.); tačiau neostigminas buvo patikimai efektyvesnis už placebą antrą pooperacinę dieną. Skausmo kontrolė ramybėje ir krūvio metu bei pacientų pasitenkinimas per visą tyrimą buvo geresni perineurinio skausmo malšinimo grupėse negu intrasąnarinėse. Intrasąnarinių grupių pacientų analgezijos efektyvumui priartėjus prie kateterinių grupių, nustatydavome didesnį papildomų analgetikų suvartojimą pirmosiose.

Many clinical studies have shown that anterior cruciate ligament (ACL) anatomical reconstruction do not allow a perfect control of anterolateral rotational instability (ALRI). This clinical postulate led to rediscovery of the anterolateral ligament (ALL). However ALL surgical reconstruction are still approximate, due to a lack of knowledge.Initially, we have studied cadaveric knees, using our own non-extensive and reproducible dissection protocol. With tis approach, we were able to define the anatomical parameters relevant to obtaining an effective ALL reconstruction. Then, we performed an histological study in order to confirm ALL ligamentary structure.In a second part, we have developed and validated a kinematic analysis protocol using a three-dimensional optoelectronic system to study the ALL role on the knee stability. Through an analysis of ALL length variations during motion and ALL section consequences, we determined the ALL capacity on ALRI control.In a third part, we were able to define, regarding our previous results, biomechanical and anatomical imperatives to perform an anatomic ALL reconstruction. In order to evaluate this technique, we analyzed and compared knee kinematics after ALL reconstruction and after lateral extra-articular tenodesis on cadaveric knees.Lastly, various clinical (laximeter, triaxial accelerometer) and morphological (MRI, ultrasound) systems were analyzed to evaluate their relevance in ALL tear diagnosis, in order to improve ALL reconstruction indications.In conclusion, this work gives a global view of ALL, from anatomical description and biomechanical function to surgical reconstruction

Patients’ knowledge about the effectiveness of interventions is now recognized as an important facilitator of the implementation of evidence in practice. Evidence-based, patient education programs aim to impart knowledge about the efficacy and effectiveness about interventions to individuals. However, there is currently a lack of structured evidence-based educational programs to educate patients about the evidence-base for interventions prescribed by the health professionals in the field of orthopaedics. OBJECTIVE: The main objective of this study was to develop and validate an Arabic version of an evidence-based educational program for patients who are scheduled to undergo ACL reconstruction surgery in UAE, based on available evidence collated through a systematic review process. METHODS: A systematic review was conducted to generate clinical recommendations which were used to develop the evidence-based educational program. The evidence-based information was derived from secondary research to determine which rehabilitation strategies were most effective in improving outcome measurements following ACL reconstruction surgery. A pre-final draft of the evidence-based educational program was prepared and forward and back translated from English into the Arabic language. Feedback groups of ACL patients and physiotherapists were used to determine the content and face validity of the program. The final draft was validated in a group of 40 ACL patients waiting to undergo ACL reconstruction surgery at Zayed Military hospital and Abu Dhabi Knee and Sports Medicine Centre in the UAE, using checklists. RESULTS: A total of 40 patients undergoing ACL reconstruction surgery consented to participate in this study. All the subjects were male. The age range was between 18 to 38 years old with mean age of 28.5 years (SD 5.75). Most of the patients (65%) underwent ACL reconstruction surgery to the right knee. Of the total sample (n=40), the majority of the subjects who participated in this study (90 %), had ACL surgery for the first time. Most of the responses to the evidence-based educational program checklist were positive. iv CONCLUSION: It can be recommended that the newly-developed evidence-based educational program is a valid tool which can be given to ACL patients prior to ACL reconstruction to prepare them for the rehabilitation postoperatively. By informing patients of their condition, the expected outcomes of their condition and the effect of doing exercises to improve their condition, the patients will be more encouraged to partake in rehabilitation, as they know it is for their own good. This will ultimately improve overall patient care and improve management of ACL patients.

Introduction: Studies have shown that, at least in soccer players, decreased ipsilateral hip range of motion has a significant influence on the occurrence of anterior cruciate ligament (ACL) injury, with a high incidence of re-ruptures especially after single-bundle reconstruction. This study aimed to compare the ability of two surgical techniques to prevent re-rupture of the ACL in soccer players with ipsilateral restricted hip joints (sum of internal and external rotation < 60°). Materials and Methods: The study was a prospective randomized clinical trial. Thirty male soccer players (mean age, 22 years; range, 18-28) with noncontact ACL ruptures were allocated to two groups. Inclusion criteria were isolated ACL injury, ipsilateral hip range of rotation below 60°, and being a professional or semi-professional soccer player. Exclusion criteria were persistent hip pain or history of any fracture or previous surgery of the lower limb. One group underwent a combined intra- plus extra-articular reconstruction (IEG), while the other was treated with double-bundle reconstruction (DBG) with semitendinosus and gracilis grafts. All patients were followed up for two years after surgery. Results: At two-year follow-up of each patient, there were three re-ruptures in the DBG vs. none in the IEG. In the 27 athletes with intact reconstructions, the amount of residual instability in the physical examination and Lachman test was about the same. Conclusion: Our findings demonstrate that, in two years of follow-up, the incidence of rerupture, although not the same, showed no significant difference between intra- plus extraarticular and double-bundle ACL reconstruction techniques in patients with ipsilateral restrained hip joints.

BACKGROUND: Each year in the US, it is estimated more than 250 million cases of anterior cruciate ligament injury, which makes surgical reconstruction a common procedure in the practice of sports medicine. There is still no consensus on how much activity to promote adequate rehabilitation without damaging the graft or produce an abnormal anterior laxity, with consequent damage to the meniscus and articular cartilage. PURPOSE: To analyze and compare the effect of an accelerated physiotherapy protocol in the anterior-stability and clinical outcome of patients undergoing reconstruction of the anterior cruciate ligament. METHODS: We included 29 subjects in the study who had total ACL rupture confirmed by MRI and underwent ligament reconstruction with patellar tendon. Patients were randomly allocated in two groups with different rehabilitation intervals: Accelerated Group (4 months) or Conventional Group (6 months). Preoperatively, six and four months postoperatively a blind evaluator recorded: anterior laxity by KT1000, Brawn (CYBEX) and knee function affected by IKDC (2000) and the Hop Test. RESULTS: the groups were similar relative to demographic data. There was no statistical difference in anterior laxity in the fourth month 0,92mm versus 1.33mm and 0.50mm in the sixth month versus 1,67mm being conventional group versus accelerated group respectively. In the fourth month the accelerated group showed a significant improvement (P <0.001) in the clinical evolution of the IKDC (2000) 79.50 versus 60.61 in the conventional group, this difference was not repeated in the sixth month. Muscle strength and the Hop Test, the fast group had higher values, but not significantly in both time points (P> 0.05). CONCLUSION: Based on these results, the Accelerated protocol when compared to conventional, do not differ as the anterior knee stability and was sufficient to establish an early significant improvement in the clinical outcome of the knee

The purpose was to verify the incorporation (healing) of the graft of the semitendinous tendon into the femoral bone tunnel after an anterior cruciate ligament reconstruction, and verify the post operative evolution of the biomechanical histology and magnetic resonance image analysis of the graft into the femoral bone tunnel. Fifteen New Zealand white rabbits were submitted to an intra-articular anterior cruciate ligament reconstruction in the left knee, using semitendinous tendon autograft. The rabbits were submitted to an magnetic resonance image at 4, 8 and 12 weeks after surgery, after which they were euthanized. The left knee of each rabbit was disarticulated and the anterior cruciate ligament reconstruction was tested for the biomechanical properties and histological analysis of the femoral tunnel. Every rabbit knee showed incorporation of the tendon at the femoral tunnel as of the fourth week in all of the knees studied. After the fourth week signs of integration occurred in the histological analysis and heterogeneous alterations in the magnetic resonance image of the graft and the surrounding areas, which suggests a healing process. Despite the biomechanical incorporation of the graft in the femoral bone tunnel after the fourth week it was not possible to affirm that there occurred incorporation of the graft until the completion of 12 weeks in histological and magnetic resonance image analysis.

This study consisted of two parts – experimental and clinical. Experimental part was conducted at the Department of Mechanization and Design Engineering of The Faculty of Technical Sciences, University of Novi Sad. Thirty two proximal tibial articular surfaces together with the anterior cruciate ligament insertion of thirty two patients were harvested during total knee arthroplasty. All patients had standard preoperative AP and profile radiographs with standard magnification in order to acquire the knee measurements. All patients previously signed the informed consent. The harvested proximal tibial articular surfaces were 3D scanned by a haptic device called „Phantom Omni®“ in order to determine the correlation between the size of the anterior cruciate ligament insertion site and the size of the tibial plateau. Thirty two randomly chosen patients of both sexes which had a knee arthroplasty were included in the experimental part of this study. All of the patients signed the informed consent at The Clinic for Orthopedic Surgery and Traumatology of The Clinical Centre of Vojvodina. The clinical part was a retrospective-prospective study. This part included 60 randomly chosen patients divided into two groups. The test group consisted of 30 patients who had undergone a revision anterior cruciate ligament reconstruction. The control group consisted of 30 patients who had undergone only primary anterior cruciate ligament reconstruction. A bone-tendon-bone graft was used for the reconstruction in all cases. The outcome was assessed by using Tegner activity scale, Lysholm knee scoring scale, IKDC score, arthrometric evaluation, Pivot shift test and the position of the graft. The results were compared between the test group and the control group. The clinical part of the study included 60 patients of both sexes, age 18-40 which were operated at The Clinic for Orthopedic Surgery and Traumatology of The Clinical Centre of Vojvodina. All of the patients signed the informed consent for participation in this study. The exclusion criteria were age under 18 and above 40, occurrence of severe general surgical complications and a patient wish to be excluded from further investigation. After a thorough analysis of the results, we concluded that the correlation between the size of the anterior cruciate ligament tibial insertion site and the size of the tibial plateau exists. Formula which was created for this study by using mathematical and statistical methods, is adequate and practically applicable for the prediction of size of the anterior cruciate ligament tibial insertion site in the majority of cases based on just two preoperative radiographic parameters – AP and profile diameter of the tibial plateau. The use of this formula may improve the outcome of the anterior cruciate ligament reconstruction. We also concluded that the cause of the primary anterior cruciate ligament reconstruction failure is multifactorial as well as that there is no statistically significant difference between the patients with good and the patients with poor graft position. We confirmed the assumption that the outcome of the revision anterior cruciate ligament reconstruction is poorer than the outcome of the primary anterior cruciate ligament reconstruction.

Introduction: Bone tunnel diameters in anatomical single-bundle anterior cruciate reconstruction cannot fulfill the footprint area. The latest studies have suggested that the anteromedial bundle might play a dominant role in ACL function at any flexion degree. This fact could support placing the bone tunnel on the anteromedial bundle footprint. However, positioning the graft at the center of the footprint could be a more efficient way to mimic part of the two-bundle function. Improper graft positioning may result in residual instability, particularly in individuals with higher functional demand, such as sport practitioners. Returning to their sport at the same level as before their injury could not be defined by knee stability alone; a global evaluation provided by more comprehensive parameters, such as postural balance, should also be included. The main purpose of this study is to compare grafts on anteromedial or central area positions in an ACL footprint. Methods: A prospective, randomized clinical study included 42 sports practitioners (Tegner > 5) with ACL injury undergoing anatomic ACL reconstruction on the anteromedial footprint (22 patients - AM group) or at the central footprint area (20 patients - Group C). The primary outcome was based on a mean center pressure (CP) mediolateral oscillation parameter analysis of each individual simulating a kicking motion on a force plate. Other posturography parameters, Tegner, Lysholm and IKDC subjective scales, a hop test and an isokinetic evaluation were considered as secondary outcomes. All results were evaluated at 6 and 12 months, with the exception of the Tegner scale, which was evaluated only at 12 months. Results; Group C presented better results in three posturography parameters when compared with Group AM: mean mediolateral plane oscillation with kicking position at 6 months (-0,43 ± 0,15cm vs. -0,87 ± 0,18cm respectively, p < 0.05), maximum CP lateral displacement with the one leg standing position at 12 months (1,05 ± 0,18cm vs. 1,28 ± 0,31 cm respectively, p < 0.05) and mean mediolateral plane oscillation with knee flexed position (0.31 ± 1.35 cm vs. -1.03 ± 1.18 cm respectively, p < 0.05) and). Group C also presented better results in the following evaluations: symmetry index in the hop test at 6 months (93 ± 7% vs. 84 ± 17% respectively, p < 0.05) and at 12 months (100 ± 7% vs. 92 ± 7%, respectively, p < 0.05) and torque peak deficit on angular velocity of 60 o/s at 6 months (12.55 ± 9.77 Nm vs. 22.9 ± 17, 89 Nm respectively, p < 0.05). CONCLUSION: Anatomic single bundle ACL reconstruction in the center of the ACL footprint shows better results compared with the anteromedial ACL footprint area in three posturography parameters related to coronal plane balance, index of symmetry in the hop test and the peak of torque deficit on an angular velocity of 60 o/s at 6 months. Surgical complications were similar in both groups
