36-year-old male with pain and locking of the left knee. Evaluate for meniscus tear. MENISCI: We see no meniscal tear.ARTICULAR CARTILAGE AND BONE: There is degeneration of the articular cartilage of the weightbearing portion of the medial femoral condyle measuring just over 1cm in diameter, with heterogeneous signal intensity and what appear to be full-thickness high signal intensity clefts traversing the cartilage as well as an underlying focus of subchondral edema-type signal. There also appears to be mild degeneration of the adjacent articular cartilage of the medial tibial plateau. There is superficial fraying of the articular cartilage of the medial facet of the patella with at least one near-full-thickness cleft. There is mild increased signal intensity of the articular cartilage of the lateral tibial plateau beneath the posterior horn of the lateral meniscus which may reflect early degeneration.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Degeneration of the articular cartilage along the medial femoral condyle and patella and other findings as described above. We see no meniscal tear.
