The adolescent knee and risk for osteoarthritis - an opportunity or responsibility for sport medicine physicians?

摘要

Knee osteoarthritis (OA) is a degenerative joint disease that affects articular cartilage, bone, and synovium. It most commonly occurs in adults over the age of 50 yr, affecting women more than men. Knee OA, unfortunately, can occur in younger adults who are in their 30s, often through sport-related joint injury (19,32). Exceptionally, degenerative joint disease can occur in children or adolescents with a syndromic disease such as Stickler syndrome, Kniest syndrome, or spon-dyloepiphyseal dysplasia (6). Knee OA risk factors and disease mechanisms include mechanical, systemic, and genetic causes.
