Pain. MENISCI: The lateral meniscus is intact. There is a truncated posterior horn of the medial meniscus with abnormal signal intensity seen consistent with a complex tear. Anterior horn of the medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is diffuse thinning of the patella cartilage. Focal full-thickness defects are seen along the middle and lateral facet. There are foci of intermediate signal intensity within the distal femoral and proximal tibial metaphysis, consistent with red marrow. No stress fracture or contusion.LIGAMENTS: ACL, PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: Quadriceps and patellar tendons are within normal limits.ADDITIONAL
1. Complex tear posterior horn medial meniscus.2. Generalized thinning of the patellar cartilage with focal areas of full-thickness cartilage loss along the middle and lateral facet compatible with degenerative change.
