There isamild reduction of the medial femorotibial compartment. The patellar shows tiny osteophytes. There are two ossified bodies posterior to the knee joint in the lateral view; which overlie on the medial femoral condyle. There is another smaller ossified body in the lateral view which is probably in the joint cavity. There is no fracture/ dislocation/ bone lesion.
