Left knee pain and swelling MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is moderate degeneration of the articular cartilage of the patellofemoral joint appearing similar to the prior examination. There has been slight progression of cartilage loss of the medial femoral condyle above the posterior horn of the medial meniscus with small full-thickness defects now evident. There is increased signal intensity of the articular cartilage of the medial femoral condyle anteriorly which appears similar to the prior exam and likely indicates mild degeneration. There is a small subchondral cyst posteriorly within the medial tibial plateau with adjacent edema appearing more prominent on the current exam. There is mild heterogeneity of the articular cartilage of the lateral compartment suggesting mild degeneration, the extent of which appears similar to the prior exam.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. No evidence of meniscal tear or Baker's cyst.2. Articular cartilage degeneration further detailed above which has progressed slightly along the medial femoral condyle.3. Small joint effusion.
