47-year-old male with right knee pain. Evaluate for meniscal tear. MENISCI: There is globular increased signal intensity within the anterior horn of the lateral meniscus that appears to extend to the tibial articular surface suggestive of a degenerative undersurface tear. There is edema type signal abnormality within the soft tissues anterior to the lateral meniscus which may represent extension of mucoid material from the anterior horn. There is globular signal intensity within the posterior horn of the medial meniscus which likely represents mucoid degeneration, but we see no discrete tear.ARTICULAR CARTILAGE AND BONE: There appears to be diffuse articular cartilage loss along the medial facet of the patella. The articular cartilage otherwise appears normal for age. The bone marrow signal intensity is within normal limits. There is a broad-based bony excrescence extending from the medial aspect of the proximal fibula which may represent a 'tug lesion' at the soleus muscle origin, of doubtful significance. LIGAMENTS: There is mild increased signal intensity within the proximal fibers of the lateral collateral ligament proper which may reflect degeneration. There is also mild intermediate signal intensity between the IT band and lateral femoral condyle which may reflect mild inflammation. The cruciate ligaments appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Findings suggestive of a degenerative tear of the anterior horn of the lateral meniscus.2. Edema and fluid tracking along the medial aspect of the gastrocnemius may represent a ruptured Baker's cyst.3. Other findings as described above.
