Male 46 years old Reason: follow-up after microfracture medial femoral condyle April of 2014. evaluate healing of microfracture History: left knee pain. MENISCI: There is attenuation of the body and posterior horn of the medial meniscus consistent with partial meniscectomy. There is fluid signal intensity within the posterior horn of the meniscus near its root consistent with a tear that we suspect extends to the inner margin of the remaining meniscus. There is also branching intermediate signal intensity within the peripheral one third of the posterior horn of the medial meniscus suggesting additional complex tearing that we suspect extends to the tibial articular surface. The anterior horn of the medial meniscus appears intact. We see no lateral meniscus tear.ARTICULAR CARTILAGE AND BONE: There is mild thinning of the articular cartilage of the weight-bearing portion of the medial femoral condyle but we see no full-thickness fluid filled defect. A small focus of signal abnormality within the subchondral bone of the weight-bearing portion of the medial femoral condyle may represent site of prior microfracture. The articular cartilage of the lateral femoral condyle and patella are relatively well preserved.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Signal abnormality within the posterior horn of the medial meniscus suggestive of a tear as described above.2. Thinning of the articular cartilage of the weight-bearing portion of the medial femoral condyle without fluid filled defect.
