The effectiveness of retrocondular release for flexor contracture in posterior stabilized total knee replacement in patients with rheumatoid arthritis.
Abstract
Flexion contracture of the knee joint in rheumatoid arthritis is a serious barrier to knee movement in osteoarthritis of the knee joint. In addition, with total knee replacement, in particular using a posterior stabilized model, a design feature may conflict with the posterior capsule, causing flexion contracture. However, few studies have focused on the anatomical aspects of knee joint. The purpose of this study was to study the anatomical location and shapes of posterior capsular attachment to the cortical layer of the femur, as well as to evaluate the effectiveness of posterior capsular release in flexion contracture by evaluating changes in knee extension angles. The group included patients operated from 2023 to 2024 at the Republican Specialized Scientific and Practical Center of Traumatology and Orthopedics (RSSPCTO) of the Republic of Uzbekistan. The posterior capsule attachment sites were examined in 31 patients who underwent posterior capsule release during total knee replacement. The release of the capsule in the retrocondular region of the femur significantly improved knee extension. Taking into account the individual bone structure of each patient and the severity of the disease, the condition of the posterior capsule. The phased retrocondular release was effective in total knee replacement.
