Лечение остеоартроза коленных суставов на основе применения клеточных технологий

Abstract

Osteoarthritis (OA) is the most common chronic disease of joint and a major cause of joint pain and disability. Traditional therapies for knee osteoarthritis show little clinical benefit, and the terminal treatment option is joint replacement. Currently, cell therapy is prospective for the treatment of knee osteoarthritis and has shown significant results in animal studies and human clinical trials. The aim: to investigate the treatment results in patients with knee osteoarthritis using adipose tissue stromal-vascular fraction and synovial mesenchymal stem cells.Methods. 60 patients with knee osteoarthritis were included in the study. The stage of knee osteoarthritis was assessed using the Kellgren-Lawrence classification, and patients with stage II-III of osteoarthritis were included in this study. After arthroscopic debridement, patients were divided into 2 groups. The first group was injected with the stromal-vascular fraction (SVF) of synovial membrane, and the second group was injected with adipose tissue mesenchymal stem cells (SVF). The minimum clinical and radiologic follow-up period was 12 months. Results. The assessment of the joints condition after 12 months using different scales showed that in both experimental groups there was a significant improvement of the functional status of the knee of the patients after treatment with MSC and SVF. Functional indicators of knee joints on the WOMAC scale improved by 14.7 and 13.4, on the KOOS scale by 23.6 and 26.4 in the SVF and MSC groups, respectively. Pain syndrome regressed by 1.8 and 2.1 on the VAS scale in the SVF and MSC groups, respectively.Conclusion. The results of both study groups showed that there is a significant difference between WOMAC, VAS and KOOS values before and after surgery (8, 12 weeks and 12 months) in the compared groups towards improvement
