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.
Summary. 1  The knee contains sacs of fluid, called bursa, that help to cushion the joint and reduce friction between the structures around it. 2  A Baker's cyst is a pronounced swelling on the back of the knee, caused by the abnormal collection of fluid inside the bursa. Treatment may include physiotherapy, drawing off the fluid with a needle, cortisone injections, treating the underlying cause, or surgery to remove the cyst.
