52-year-old male with medial joint line pain, evaluate for meniscal tear. MENISCI: There is slight blunting of the free edge of the body of the medial meniscus seen on the coronal images, not evident on the prior study. There also appears to be a defect in the femoral surface fibers of the inner aspect of the body of the medial meniscus, seen on the sagittal images. These findings are suggestive of a tear, unless the patient has undergone a prior partial meniscectomy. There is also mild fraying of the undersurface fibers of the posterior horn of the medial meniscus. The anterior horn of the medial meniscus appears normal. There is a thin vertically oriented linear focus of high signal intensity in the posterior horn of the lateral meniscus near its root, but this appears similar to the prior study and is not necessarily of any current clinical significance.ARTICULAR CARTILAGE AND BONE: There is a focal full-thickness defect of the articular cartilage near the median eminence of the patella that appears slightly more prominent on the current study. There is a small subchondral cyst within the patella underlying this defect, appearing similar to the prior study. There is mild superficial fraying of the articular cartilage of the medial and lateral facets, appearing similar to the prior study. The articular cartilage of the medial tibiofemoral compartment appears subjectively thinned, perhaps slightly more than on the prior study, suggesting mild degeneration. Mild subchondral edema type signal within the far medial aspect of the medial tibial plateau and medial femoral condyle is likely degenerative in etiology.LIGAMENTS: The medial collateral and lateral collateral ligament complexes are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Defect of the articular cartilage of the patella appearing slightly more prominent on the current study with additional areas of degeneration as described above.2.Findings suggestive of a tear of the inner fibers of the body of the medial meniscus as described above.
