Intra-articular body within the suprapatellar recess. Donor site is medial femoral condyle with a large well-demarcated osteochondral defect without adjacent marrow edema. Chondral fraying at the edges of the osteochondral defect. Subchondral marrow edema of both the medial and lateral tibial plateaus.
Case Discussion
Chronic medial femoral condyle osteochondral defect with the fragment migrated into the suprapatellar recess correlates with stage IV. While there is chondral degeneration present, there is no established secondary osteoarthritis.
