Introduction Degenerative diseases of the musculoskeletal system take one of the first places worldwide in terms of human disability (James et al., 2018). Arthritic diseases of various types are inflammatory diseases of human joints, in which cartilage destruction occurs. In the early stages of the disease, conservative methods of treatment are used to prevent the destruction of cartilage tissue: pharmaceutical treatment, physical activity, physiotherapy, bodyweight control.
