63-year-old male with knee pain. MENISCI: There is increased signal abnormality which extends to the tibial and femoral articular surface with associated deformity of the posterior horn of the medial meniscus consistent with a complex but predominantly radial tear. The anterior horn of the medial meniscus appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness to full-thickness articular cartilage degeneration along the medial facet of the patella. There is focal full-thickness articular cartilage degeneration along the lateral facet of the patella with bone marrow edema type signal abnormality in the surrounding area, likely degenerative in etiology. There is superficial fraying of the articular cartilage of the femoral trochlea. There is near full thickness articular cartilage degeneration along the posterior aspect of the medial femoral condyle above the posterior horn of the medial meniscus.LIGAMENTS: There is increased signal abnormality about the MCL suggestive of a MCL sprain. The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Tearing of the medial meniscus as described above.2. Articular cartilage degeneration as described above.3. Findings suggestive of a partially ruptured Baker's cyst.
