Right knee pain MENISCI: There is thinning and horizontally oriented increased signal intensity involving the posterior horn of the medial meniscus which extends to the tibial articular surface and is compatible with tear. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is marked full-thickness cartilage loss of the lateral femoral condyle, particularly anteriorly. This is superimposed upon mild diffuse thinning of the lateral compartment. Similar full-thickness loss is noted involving the medial femoral condyle anteriorly with full-thickness loss of the medial tibial plateau. There are areas of near full-thickness loss involving the lateral patellar facet with areas of heterogeneous signal intensity seen more centrally.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Predominantly horizontal tear of the posterior horn of the medial meniscus.2. Full-thickness cartilage loss of both the lateral and medial femoral condyle anteriorly with additional areas of cartilage loss and thinning detailed above.
