Comparison of the techniques of valgus osteotomy with resection osteotomy of the fibula in combination with sanitation arthroscopy. Resection of the fibula, debridement arthroscopy is characterized by minimally invasiveness, targeted therapeutic effect on the focus of destruction of the cartilaginous cover, removal of inflammatory mediators with abundant lavage, low-trauma intervention. Abrasive chondroplasty, subchondral tunneling during arthroscopy make it possible to create conditions for reparative processes, and the formation of hyaline-like cartilage in the defect zone. Corrective osteotomy may result in fractures of the tibial plateau, fractures of the cortical loop (instability of fixation), false joints, and fractures of metal structures.

Introduction. Despite the fact that instability of the patella is a common pathology within the structure of knee joint diseases and injuries in children, currently there is no complete information on the basis of which one could judge the effectiveness and preference of a particular method of treating instability of the patella in children. Purpose of study: to evaluate the efficacy of surgical treatment techniques in children with post-traumatic instability of the patella. Patients and methods. The study was performed on the basis of examination and treatment data on 127 patients aged from 8 to 17 years with post-traumatic instability of the patella. Arthroscopic stabilization by Yamamoto technique, modified at our department, was performed in 49 patients, patella stabilization with transposition of the tibial tuberosity - in 67 patients, with the medial patellofemoral ligament autoplasty - 9, corrective osteotomy - in 2. Treatment efficacy was assessed using AKPS and 2000 IKDC knee joint assessment scores. The questionnaires were carried out at admission, in 1, 2-4 and 4-7 years after surgery. Results. At early terms after operation (up to 2 years) in the group of children after stabilization of the patella by modified Yamamoto technique good and excellent results were observed in 77.8% of cases, after transposition of the tibial tuberosity - in 73.3%, after stabilization of the patella with medial patellofemoral ligament autoplasty - in 88.9%. Long-term follow up (5-7 years) showed 90.9 and 86.5% of cases from the 1st and 2nd groups, respectively. Conclusion. The proposed algorithm for examination and treatment provides the most effective treatment and enables to obtain good and excellent results in the majority children with post-traumatic instability of the patella.

Abstract Background:The popliteal muscle-tendon complex (PMTC) belongs to the deep structure of the posterolateral complex (PLC) of human knee, which plays an important role in the posterolateral stability of the knee joint. At present, the anatomical relationship between the popliteal muscle and its adjacent structures remains controversial, especially the posterior cruciate ligament (PCL) and popliteal muscle. The revealation of anatomical connection between the popliteus muscle and its deep structures could provide an anatomical basis for the reconstruction of the PLC injury.Methods: To observe and analyze the relationship between popliteal muscle and the PCL, posterior meniscofemoral ligament (PMFL), lateral meniscus and articular capsule (AC). The dissection of 7 cases of adult human knee joint fixed with formalin, and 9 cases of sagittal P45 plastinated section of the knee joint were involved in this study. Results: For the popliteal muscle, the anatomical dissection showed that at the posterior edge of the platform of the lateral condyle of the tibia, at the tendon-muscle transition, from medial to lateral, separately sent out: dense connective tissue to connect with the PCL, dense fiber bundles to connect with the PMFL, and dense connective tissue band to connect the lateral meniscus. Meanwhile, the results of the P45 section revealed that the popliteal muscle fascia ran superiorly over the posterior edge of the tibialintercondylar eminence, andturned forward to be integrated into the PCL. Laterally, near the posterior edge of the lateral tibial plateau, the popliteal tendon penetrates through the articular capsule, where two dense fiberous bundleswere given off upwards by the popliteal tendon: one was the ventral fiber bundle,which ran superiorly over the posterior edge of the tibial plateau and then moved forwards to connect with the lateral meniscus; the dorsal fibersbundle ascended directly and participated in the AC.Conclusion: Popliteus muscle was connected with PCL, AC, lateral meniscus, and PMFL via the dense connective tissues near its tendon-muscle transition.

Objective Osteoarthritis (OA) literature makes minimal suggestion regarding age of disease onset or preventative strategies to reduce risk for onset in various populations. In 2005, the Centers for Disease Control and Prevention estimated that 33.6% of Americans 65+ years old were affected by OA; this cadaveric analysis suggests this is largely underestimated. The objective of this assessment is to identify at-risk populations for OA in the knee joint and make recommendations to prevent or delay disease onset. Design Morphometric analyses of the articular cartilage of the tibial plateau were performed on cadaver specimens using Image Pro software on 3 age populations and surface area measurements for articular cartilage degradation were compared with donors’ reported ages, clinical histories, and occupations. Results Data showed that by the seventh decade of life, when patients are in their 60s, articular cartilage degeneration on the tibial plateau had commenced in 100% of specimen. All “homemakers” displayed above-average medial tibial plateau degeneration (32.33% ± 24.85%) for their age group while simultaneously reporting pathologies in their clinical history that encourage a sedentary lifestyle. Conclusions This assessment identifies an occupational class with a propensity to develop disease and also identifies a more realistic time frame than previous advisory committees have produced regarding age of disease onset and initiation of preventative measures. It is recommended that strengthening of the hip abductors and the musculature supporting the knee commence early in adult life to avoid valgus collapse and shearing at the knee joint.

Menisci are fibrocartilagenous structures located between the femoral condyles and tibial plateau that aid in joint lubrication and stability in the knee joint. Previous experimental and theoretical studies have shown that the meniscal horn attachments, which serve as the transition from mensical fibrocartilage into subchondral bone, are important for proper meniscal function [1–3]. Meniscal attachments did not show significant differences in surface mechanical properties such as ultimate strain or moduli, however, there were significant differences in overall behavior of the anterior versus posterior attachments [4]. No significant differences in creep or stress relaxation properties were found between the different meniscal attachments [5].
