Abstract (sommario):

Background: Anterolateral complex injuries are becoming more recognized. While these are known to affect tibiofemoral mechanics, it is not known how they affect patellofemoral joint behavior. Purpose: To determine the effect of (1) sectioning the anterolateral complex and (2) performing a MacIntosh tenodesis under various conditions on patellofemoral contact mechanics and kinematics. Study Design: Controlled laboratory study. Methods: Eight fresh-frozen cadaveric knees were tested in a customized rig, with the femur fixed and tibia free to move, with optical tracking to record patellar kinematics and with thin pressure sensors to record patellofemoral contact pressures at 0°, 30°, 60°, and 90° of knee flexion. The quadriceps and iliotibial tract were loaded with 205 N throughout testing. Intact and anterolateral complex–sectioned states were tested, followed by 4 randomized tenodeses applying 20- and 80-N graft tension, each with the tibia in its neutral intact alignment or left free to rotate. Statistical analyses were undertaken with repeated measures analysis of variance, Bonferroni post hoc analysis, and paired samples t tests. Results: Patellar kinematics and contact pressures were not significantly altered after sectioning of the anterolateral complex (all: P > .05). Similarly, they were not significantly different from the intact knee in tenodeses performed when fixed tibial rotation was combined with 20- or 80-N graft tension (all: P > .05). However, grafts tensioned with 20 N and 80 N while the tibia was free hanging resulted in significant increases in lateral patellar tilt ( P < .05), and significantly elevated lateral peak patellofemoral pressures ( P < .05) were observed for 80 N. Conclusion: This work did not find that an anterolateral injury altered patellofemoral mechanics or kinematics, but adding a lateral tenodesis can elevate lateral contact pressures and induce lateral patellar tilting if the tibia is pulled into external rotation by the tenodesis. Although these in vitro changes were small and might not be relevant in a fully loaded knee, controlling the position of the tibia at graft fixation is effective in avoiding overconstraint at time zero in a lateral tenodesis. Clinical Relevance: Small changes in lateral patellar tilt and patellofemoral contact pressures were found at time zero with a MacIntosh tenodesis. These changes were eliminated when the tibia was held in neutral rotation at the time of graft fixation. The risk of overconstraint after a lateral tenodesis therefore seems low and in accordance with recent published reports.

Abstract (sommario):

The anterolateral structures of the knee have been demonstrated to have a significant impact on reducing rotational instability and the forces applied to the anterior cruciate ligament reconstruction (ACL) graft after surgical reconstruction. Combined ACL reconstruction and lateral extraarticular tenodesis are being performed at an increasing number due to its promising outcome in properly indicated patients. However, tunnel convergence in combined ACLR and lateral extraarticular tenodesis can lead to graft damage and possible failure defeating the purpose of this very effective technique. This technical note describes how to avoid knee tunnel convergence when performing a combined ACL reconstruction with lateral extraarticular tenodesis utilizing the “Antero medial window”.

Abstract (sommario):

Each of six below-the-knee amputation specimens were transfixed to a wooden block and mounted to a jig on an amputee testing device preloaded with 5 N applied to the proximal phalanx and displaced at a constant rate of 2 mm/min. Load displacement curves were generated for the intact joint and after sequential incisions of the lateral capsule, the adductor hallucis, and the lateral slip of the flexor hallucis brevis tendon, which caused varus dislocation of the hallux. An extensor hallucis brevis tenodesis was performed after the varus dislocation. Division of the lateral capsule, the adductor, and the flexor brevis reduced the force required to displace the hallux by 42.2%, an additional 25.2%, and a further 14.2%, respectively. Use of the extensor hallucis brevis tenodesis restored the load displacement curves to that of the normal joint. We concluded that the extensor hallucis brevis tendon may be useful as a tenodesis for reconstructing the deformity of acquired hallux varus.

Abstract (sommario):

Introduction: Peroneal disorders are a common cause of ankle pain and lateral instability and have been described in as much as 77% of patients with lateral ankle instability. Clicking, swelling, pain, and tenderness in the peroneal tendons track are frequent symptoms, but they can be confused with other causes of lateral ankle pain. The management of peroneal disorders can be conservative or surgical. When the conservative treatment fails, surgery is indicated, and open or tendoscopic synovectomy, tubularization, tenodesis or tendon transfers can be performed. The authors present a surgical technique of tendoscopy associated to minimally invasive tenodesis for the treatment of peroneal tendon tears, as well as the preliminary results of patients submitted to this procedure. Methods: Four patients with chronic lateral ankle pain who were diagnosed with peroneal brevis pathology were treated between 2020 and 2022 with tendoscopic-assisted minimally invasive synovectomy and tenodesis. Using a 2.7 mm 30° arthroscope and a 3.0 mm shaver blade, the entire length of the peroneus brevis tendon and most parts of the peroneus longus tendon can be assessed within Sammarco’s zones 1 and 2. After the inspection and synovectomy, a minimally invasive tenodesis is performed. Results: All patients were evaluated at least six months after surgery. All of them reported improvement in daily activities and in the Foot Function Index (FFI) questionnaire (pre-surgery mean FFI = 23.86%; post-surgery mean FFI = 6.15%), with no soft tissue complications or sural nerve complaints. Conclusion: The tendoscopy of the peroneal tendons allows the surgeon to assess their integrity, confirm the extent of the lesion, perform synovectomy, prepare the tendon for tenodesis, and perform it in a safe and minimally invasive way, reducing the risks inherent to the open procedure.

Abstract (sommario):

Chronic ankle instability can result from untreated or badly managed acute lateral ankle ligament injuries. Conservative management is the modality of choice for acute lateral ankle ligament injuries, and operative treatment is reserved for special cases. Failure after strict rehabilitation may be an indication for surgery. Several operative options are available, including anatomic repair, anatomic reconstruction, and tenodesis procedures. Anatomic repair can be performed when the quality of the damaged ligaments permits. Anatomic reconstruction with an autograft or allograft should be considered when the torn ligaments are not adequate. Ankle arthroscopy is a useful adjunct to ligamentous procedures, performed at the time of repair to identify and treat intra-articular conditions that may be associated with chronic ankle instability. Tenodesis techniques are not recommended because of their suboptimal long-term results related to the modification of ankle and hindfoot biomechanics. Level of Evidence: Level V, expert opinion.

Abstract (sommario):

Objectives Anterior cruciate ligament (ACL) arthroscopic reconstruction with a patellar tendon graft (BTB) is a well-known and reliable surgical option for control of anterior laxity, at short and middle term. Most of those patients are young and practice sports, often at high level. Few studies have evaluated the long term effects of ACL reconstruction, and more specifically lateral tenodesis, on knee function. It has been shown that chronic anterior instability, when left untreated, evolves towards femorotibial osteoarthritis in the 10 to 20 years after ACL rupture. This study aims to compare long-term survival and femorotibial arthritis between ACL reconstruction with and without lateral tenodesis. Methods 121 consecutive knees (120 patients) presenting with an ACL rupture between 1998 and 1999 were included in this prospective randomized monocentric study. For the 61 knees in group BTB, an isolated patellar tendon plasty with outside-in technique was performed. For 60 knees in group BTB-T, the intra-articular plasty was associated with a lateral tenodesis with gracilis tendon. Patients were reviewed at 1 year, 6 years and 19 years post-operatively. Results 80 patients were contacted with a minimum follow-up of 19 years. 43 patients had a clinical examination and the 37 other patients were evaluated through a telephone questionnaire. We had standard X-rays for 45 patients and laximetry (TELOS™) for 42 patients. 41 patients (34%) were lost to follow-up. 16 knees (20%) had experienced a graft failure, 5 of which had had an iterative ACL plasty. The difference between group BTB (27.5%) and group BTB-T (13.2%) concerning graft failure was not statistically significant (p = 0.38). 32 patients (71%) had femorotibial osteoarthritis (IKDC grade C or D). There was no difference between groups BTB and BTB-T concerning medial femorotibial osteoarthritis. Lateral femorotibial osteoarthritis was significantly increased in groupe BTB-T (59%) compared to group BTB (21%) and to the contralateral knee (5%). 36 patients (45%) had had a lateral or medial meniscectomy. Mean subjective IKDC score was 81.8/100, comparable between groups BTB and BTB-T. 67% still practiced pivot sports. Conclusion At 19 years follow-up after patellar tendon ACL plasty, lateral tenodesis did not significantly improve graft survival in our study. Lateral femorotibial osteoarthritis was significantly increased in patients with a lateral tenodesis. However, a follow-up bias may be that lesions of the lateral meniscus were more frequent in BTB-T patients for whom we obtained X-rays. Functional scores were stable at over 80/100 and two thirds of patients still practiced pivot sports. ACL graft survival was 80% at 20 years follow-up.

Abstract (sommario):

One of the most devastating effects of tetraplegia is the inability to grasp and manipulate everyday objects necessary to living an independent life. Currently surgery is widely accepted as the solution to improve hand functionality. However, surgery becomes difficult when the user has paralysed wrists as is the case with C5 tetraplegia. The aim of this research was to develop a solution which provided controlled wrist flexion and extension which, when combined with surgery, achieves a 'key pinch' grip. This particular grip is critically important for people with C5 tetraplegia as it is used for countless grasping activities, necessary on a day-to-day basis. A systematic design process was used to evolve the solution to provide controlled wrist flexion and extension. Concept brainstorming identified four alternative solutions which were evaluated to find the preferred concept. The chosen solution was called the Self Powered Wrist Extension Orthosis, more commonly referred to as the 'orthosis'. This concept contained a shoulder harness which provided both energy and control to the wrist harness, which in turn changed the wrist position. The orthosis was developed with the use of a mathematical model which theoretically predicted the functional performance by comparing the required force needed to move the wrist harness to the achievable force supplied by the user's shoulders. Using these parameters, the orthosis was optimized using the matlab Nelder-Mead algorithm which adjusted the wrist harness geometries to maximize the functional performance. A prototype was constructed and tested with the help of two participants who when combined, achieved an average of 18.5° of wrist rotation. The theoretical model however predicted an average range of motion of 28.4°. The discrepancy found between the theoretical and experimental result can be contributed to incorrect assumptions in the theoretical model. This included unaccounted friction and inaccurate modeling of the orthosis dynamics. The feedback from potential users of the orthosis was enthusiastic and encouraging especially towards the simplicity, usability and practicality of the design.

Abstract (sommario):

Le contrôle du ressaut rotatoire induit par la rupture du ligament croisé antérieur est un enjeu majeur de la chirurgie ligamentaire du genou. L’association d’une ténodèse latérale à la reconstruction du ligament croisé antérieur améliore ce contrôle comparativement à une plastie intra-articulaire isolée. Pour autant, l’utilisation de ces ténodèses ne fait pas l’unanimité au sein de la communauté orthopédique. Leur intérêt a été à l’origine de ce projet de recherche anatomique, biomécanique et clinique. Au niveau anatomique et biomécanique, le contrôle rotatoire du genou est assuré par le ligament croisé antérieur et le ligament antéro-latéral. Au niveau technique, la réalisation de ténodèses latérales doit respecter des critères précis pour restituer la fonction du ligament antéro-latéral via le concept d’anisométrie favorable. Au niveau clinique, le contrôle du ressaut est amélioré cette plastie latérale additionnelle. Cette association de plasties ligamentaires a rendu la chirurgie plus complexe et ouvert la voie à un autre projet recherche sur l’utilisation de technologies innovantes pour améliorer la précision et la personnalisation du geste chirurgical
Treatment of the rotational instability induced by rupture of the anterior cruciate ligament is a major challenge in knee ligament surgery. Combining lateral tenodesis with anterior cruciate ligament reconstruction improves this control compared to isolated intra-articular plasty. However, the orthopaedic community is not unanimous about the use of lateral tenodesis. Their interest was at the origin of this anatomical, biomechanical and clinical research project. Anatomically and biomechanically, rotational control of the knee is ensured by the anterior cruciate ligament and the anterolateral ligament. Technically, lateral tenodesis must respect precise criteria to restore the function of the anterolateral ligament, via the concept of favorable anisometry. Clinically, this additional lateral plasty enhances rotational stability.This association of ligament reconstructions has increased the complexity of surgical procedures and spurred further research using innovative technologies to enhance accuracy and a more personalizated surgery
