Bone Chips in the Knee (Osteochondritis Dissecans) Osteochondritis dissecans is a knee problem caused by an injury to the bones or cartilage of the knee joint. The cartilage covering the femur (thighbone) or patella (kneecap) is usually affected. (Cartilage is the tissue that lines and cushions the surface of the joints.) Fragments or chips of bone or cartilage may come loose and float around in the knee joint.
A lubricating fluid called synovial (sih-NO-vee-ul) fluid helps your leg swing smoothly and reduces friction between the moving parts of your knee. But sometimes the knee produces too much synovial fluid, resulting in buildup of fluid in an area on the back of your knee (popliteal bursa), causing a Baker's cyst. This can happen because of: 1  Inflammation of the knee joint, such as occurs with various types of arthritis.  A knee injury, such as a cartilage tear.
