[Treatment of flexion contracture of the knee joint in rheumatoid arthritis]

In 45 patients with rheumatoid arthritis 55 posterior capsulotomies with extension of the bicipital tendon were performed since 1973, using the method described by Wilson (1929), Herbert (1950) and Gschwend (1977). 35 patients with 45 operated knee joints could be followed up. The follow-up period was 6 months to 6 years. In more than 80% of the cases an improvement of extensibility over 20 degrees as well as of walking distance and security of gait could be achieved. Pain was relieved in the same proportion and, likewise, the patients' dependence on walking aids.
