26-year-old male with knee pain. Evaluate for medial meniscal tear. MENISCI: The medial and lateral menisci appear intact. ARTICULAR CARTILAGE AND BONE: No full-thickness articular cartilage defects are identified. No bone marrow signal abnormality is seen.LIGAMENTS: The medial collateral ligament appears intact. There is a small amount of fluid between the superficial and deep fibers of the MCL which could represent a mild bursitis, but this is of uncertain clinical significance. The LCL appears intact. The ACL and PCL appear intact. EXTENSOR MECHANISM: There is thickening of the proximal patellar tendon indicating tendinosis with a partial-thickness tear of the undersurface fibers at the patellar attachment. The quadriceps tendon appears intact.ADDITIONAL
1. No evidence of a meniscal tear.2. Partial-thickness tear of the undersurface fibers of the patellar tendon at the patellar attachment.3. Small focus of fluid signal intensity between the deep and superficial fibers of the MCL may represent a mild bursitis, but this is of questionable clinical significance.
