Left knee pain and swelling MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is partial-thickness degeneration of the articular cartilage along the patella. A defect noted along the median eminence seen on the prior exam is less prominent currently. However there is a new near full-thickness cleft along the medial facet. Additional near full-thickness cleft is seen inferiorly along the median eminence which was likely present on the prior exam. There is a near full-thickness defect of the femoral trochlear cartilage centrally and inferiorly measuring approximately 8 mm. This appears more prominent on the current exam.There is mild heterogeneity of the lateral tibial plateau suggesting mild cartilage degeneration, which is similar to the prior exam.There is mild heterogeneity of the articular cartilage of the medial femoral condyle above the free edge of the posterior horn of the meniscus suggesting mild degeneration. This appears less prominent on the current exam. There is also increased signal intensity more anteriorly within the articular cartilage of the medial femoral condyle suggesting delamination. There is a small cyst within the medial tibial plateau posteriorly which was present on the prior exam. The surrounding bone marrow edema in this area has resolved. The remaining bone marrow signal is otherwise normal.LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
