Correlation between sarcopenya and knee osteoarthritis in the elderly patients group (systemic review)

RELEVANCE. Sarcopenia and knee osteoarthritis are the most common age-related diseases, which are an important part of the public health indicators of elderly patients around the world. Osteoarthritis is a chronic joint disease that is closely related to aging. It is characterized by degeneration of cartilage, abnormal remodeling of subchondral bone and the formation of osteophytes at the edge of the joint, which cause severe pain and lead to disability. Osteoarthritis is the most common joint disease worldwide, affecting about 10 % of men and 18 % of women aged 65–70. Common cases of osteoarthritis increased by 113.25 % worldwide in 30 years, from 247.51 million in 1992 to 527.81 million in 2022. Recent studies have identified various risk factors associated with knee osteoarthritis, including obesity, sedentary lifestyle, joint injuries, high-intensity sports activities and muscle loss. Conclusions about the relationship between muscle mass and osteoarthritis of the knee joint are different. Sarcopenia, progressive and generalized skeletal muscle disease,affecting from 10 % to 16 % of the elderly worldwide. The Elderly Sarcopy Working Group (EWGSOP) updated the Sarcopy consensus, emphasizing low muscle strength as the main characteristic of geriatric syndrome.
