Assess for progression of subchondral edema. MENISCI: Severe blunting of the body of the medial meniscus likely reflects postsurgical changes. No definite superimposed tear is present. Signal characteristics and morphology of the lateral meniscus are unremarkable without evidence of discrete tear.ARTICULAR CARTILAGE AND BONE: Full-thickness thickness cartilage defect of the weightbearing portion of the medial femoral condyle is stable to slightly larger than seen previously, measuring approximately 12 mm. There is mild thinning of the articular cartilage of the of the lateral femoral condyle without full-thickness cartilage defect. Focal near full-thickness articular cartilage degeneration of the lateral tibial plateau immediately lateral to the tibial spine is unchanged. Near full-thickness degeneration of the medial patellar facet as well as focal near full-thickness defect of the lateral patellar facet appears similar to the previous exam. Near full-thickness degeneration of the medial and lateral femoral trochlea and full-thickness defect at the central femoral trochlea are also unchanged.Bone marrow edema in the medial femoral condyle is grossly unchanged.LIGAMENTS: There is thickening and increased signal abnormality in the anterior cruciate ligament, suggestive of progressive partial chronic tearing.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Full-thickness cartilage defect of the medial femoral condyle redemonstrated.2.No significant interval change in bone marrow edema of the medial femoral condyle.3.Articular cartilage degeneration and focal defects are grossly stable, as detailed above.
