Association of bone marrow lesions with knee structures and risk factors for bone marrow lesions in the knees of clinically healthy, community-based adults.

Objectives: Subchondral bone marrow lesions (BML) are involved in pain and progression of knee osteoarthritis (OA). Little is known about their role in the knee in those without clinical OA. Our aim was to examine the prevalence and risk factors for BML, and their relationship with other knee structures in community-based adults without clinical OA.
