Musculoskeletal Pain and Disability in the Knee Joint

Knee Program

Osteoarthritis is the most common cause of musculoskeletal pain and disability in the knee joint. In the knee joint, the end of the femur (thigh bone) and tibia (shin bone) are covered in smooth articulate cartilage. Between the two bones sits a second type of cartilage, called menisci, which act as cartilage shock absorber pads. Joint fluid also adds lubrication to the knee joint.

Osteoarthritis (OA) starts as the lack or loss of this articulate (surface) cartilage and then progresses into involvement with the surrounding bone, tissues, and synovial fluid. In osteoarthritis, cartilage may have areas of partial thickness loss (thinning) or complete loss of surface cartilage resulting in areas of exposed bone. Isolated cartilage loss may be a result of isolated trauma or it may be a result of chronic wear and tear of the joint.
