Arthroscopic arthrolysis in treatment of contractures after knee joint arthoplasty

Background: One of the most serious complications of total knee arthroplasty is contracture associated with the formation of coarse fibrous connective tissue in the joint cavity (arthrofibrosis). This complication occurs in 1,3-5,7% of cases and requires surgical treatment. Aims: Improving the quality of care for patients with contractures after arthroplasty of the knee joint by improving the technique of arthroscopic arthrolysis. Materials and methods: The work is a single-center, prospective, selective, non-controlled study. The object of the study was 57 patients with contractures of the knee joint after arthoplasty for idiopathic gonarthrosis of the III stage. There were 50 female (87,7%), 7 male (12,3%), and the average age of the patients was 63,8±12,2. For contracture after arthroplasty of the knee, arthroscopic arthrolysis was performed. The study was conducted from 2015 to 2019. The effectiveness of the treatment was evaluated by the change in the range of movements and functional indicators determined on the KSS scale before and after 2 weeks, 3, 6 and 12 months...
