Updates to Study Attributes

Findings was changed:

There isamild reduction of the medial femorotibial compartment. The patella shows tiny osteophytes. There are two ossified bodies posterior to the knee joint in the lateral view; which overlie 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/, dislocation or bone lesion.

There is a cyst on the posteromedial side of the knee with echogenic ossified bodies in it. The cyst showed a communicating neck between the medial head of the gastrocnemius muscle and the semimembranosus tendon (image not uploaded).
