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.
Chondromalacia, also known as ârunnerâs knee,â is a condition where the cartilage on the undersurface of the patella (kneecap) deteriorates and softens.his rubbing can lead to deterioration in the patella, and then chondromalacia or runnerâs knee. Improper kneecap movement may result from: 1  poor alignment due to a congenital condition. 2  weak hamstrings and quadriceps (the muscles in the back and front of your thighs).
