60-year-old female with popping, locking and catching. Mild osteoarthritis on recent radiographs. Evaluate medial meniscus. MENISCI: Note is made of increased branching linear signal abnormality within the posterior of the medial meniscus which extends to the tibial and femoral articular surface consistent with a complex tear with both a radial and horizontal component. There is also linear increased signal abnormality within the posterior horn and body of the medial meniscus which does not definitively extend to either articular surface. The anterior horn of the medial meniscus appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is bone marrow signal abnormality within the medial aspect of the tibial plateau and to a lesser degree within the medial femoral condyle consistent with bone contusion. No full-thickness or near full-thickness articular cartilage defects are identified. There is a partial-thickness articular cartilage fissure along the lateral facet of the patella, centrally.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Tearing of the medial meniscus as described above.2. Partial-thickness articular cartilage fissure along the patella and bone contusions as described above. 3. Small joint effusion. Other findings as described above.
