38-year-old male with knee pain, patellar tendon pain. MENISCI: There is globular intrasubstance signal within the body and posterior horn of the medial meniscus indicating intrasubstance degeneration. The root of the posterior horn of the medial meniscus is essentially replaced with abnormal signal intensity and does not definitively contact the tibial articular surface, presumably representing a root avulsion tear. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is subjective thickening of the articular cartilage of the medial compartment. The articular cartilage of the lateral compartment appears relatively spared. The articular cartilage of the patellofemoral compartment also appears relatively spared. The bone marrow signal intensity is within normal limits.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: There is minimal increased signal intensity within the undersurface fibers of the proximal patellar tendon which may represent mild tendinosis but is of questionable clinical significance. The extensor mechanism appears intact.ADDITIONAL
1. Root avulsion tear of the medial meniscus as described above.2. Articular cartilage degeneration as described above.3. Findings suggestive of minimal patellar tendinosis of questionable clinical significance.4. Nonspecific subcutaneous edema along the anterior aspect of the patellar tendon.5. Findings suggestive of a mild synovitis and joint effusion.
