what is a floater in the knee
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.
