The aim of the study – Is to evaluate the effectiveness and safety of the use of a functional unloading orthosis with the possibility of varus–valgus correction (FUOVVC) in patients with stage III osteoarthritis of the knee joint. Materials and methods. The study involved 10 patients with stage III osteoarthritis of the knee joint who underwent outpatient treatment at the V.A. Nasonova Federal State Medical University of the Russian Academy of Medical Sciences. All patients used the FUOVVC for 3 months. To evaluate the results, pain intensity was determined using a visual analog scale (VAS) and knee joint function according to the knee injury and osteoarthritis KOOS (Knee injury and Osteoarthritis Outcome Score) questionnaire before using the orthosis, after 1 and 3 months. Additionally, the assessment of VAS was carried out immediately after fixation of the orthosis on the knee joint. Results. The median age of the patients was 63.5 [55.0; 74.0] years, body mass index – 29.9 [27.9; 34.0] kg/m 2 , pain according to VAS baseline – 40.0 [40.0; 60.0] mm, pain according to VAS 1 hour after the start of the use of The median age of the patients was 63.5 [55.0; 74.0] years, body mass index – 29.9 [27.9; 34.0] kg/m 2 , pain according to VAS baseline – 40.0 [40.0; 60.0] mm, pain according to VAS 1 hour after the start of the use of FUOVVC – 25.0 [10.0; 30.0] mm, pain according to VAS after 1 month – 10.0 [0.0; 20.0] mm, VAS after 3 months – 10.0 [0.0; 20.0] mm. The median score according to the KOOS questionnaire was initially 41.5 [38.0; 50.0], after 1 month – 61.0 [53.0; 63.0], after 3 months – 63.5 [58.0; 64.0]. None of the patients had any adverse events when wearing the FUOVVC. – 25.0 [10.0; 30.0] mm, pain according to VAS after 1 month – 10.0 [0.0; 20.0] mm, VAS after 3 months – 10.0 [0.0; 20.0] mm. The median score according to the KOOS questionnaire was initially 41.5 [38.0; 50.0], after 1 month – 61.0 [53.0; 63.0], after 3 months – 63.5 [58.0; 64.0]. None of the patients had any adverse events when wearing the FUOVVC.
