Left knee pain, evaluate for chondral defect. Per Epic, history of partial medial meniscectomy. MENISCI: There is blunting of the free edge of the medial meniscus compatible with prior meniscectomy. The medial meniscus appears somewhat extruded laterally. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is a 7 x 11 mm focus of abnormally decreased T1 signal and increased T2 signal along the lateral aspect of the medial femoral condyle (8/15) compatible with an osteochondral defect. A large segment of cartilage overlying this lesion appears to have delaminated for length of approximately 16 mm in AP dimension (6/10). The osseous component of the lesion lacks underlying linear T2 signal abnormality to suggest instability. Bone marrow edema and subchondral cyst formation is present within the medial femoral condyle adjacent to the osteochondral defect. The remaining cartilage of the knee appears intact.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
