M24: Other specific joint derangements

M24.1: Other articular cartilage disorders

Other articular cartilage disorders, coded as M24.1 in the ICD-10 WHO 2016 classification, refer to a range of conditions affecting the articular cartilage. This cartilage serves as a cushion inside joints, helping the bones glide smoothly. When disorders occur, it can interfere with this role, leading to joint pain and dysfunction. Disorders might result from a variety of factors such as wear and tear over time, known as degenerative changes, or from injuries to the joint. Common symptoms often include joint pain, swelling, stiffness, and reduced range of motion. While these disorders can occur in any joint, they frequently affect weight-bearing joints like the knees and hips. Progression of the condition may lead to narrowing of the joint space and impairment of joint function due to damage to the articular cartilage.
