Initial MRI revealed no osteochondral defect, and he was treated conservatively. As symptoms worsened, serial MRI revealed a progressive medial femoral condyle lesion with subchondral depression. He subsequently underwent an osteochondral allograft transplantation and achieved a full recovery. The time from initial presentation to diagnosis was approximately 7 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Progressive osteochondral defects may not be visible on initial MRI.
