Reason: Is there a new or persistent meniscus tear? Or articular cartilage damage? History: s/p lateral partial meniscectomy with persistent pain MENISCI: There is blunting of the free edge of the body of the lateral meniscus, compatible with history of prior partial lateral meniscectomy. Additionally however, there is vertically oriented increased signal intensity within the peripheral red zone of the body of the lateral meniscus extending to the tibial articular surface, indicating a tear. This may be associated with a very small parameniscal cyst. Medial meniscus is normal in signal characteristics and morphology.ARTICULAR CARTILAGE AND BONE: There is subchondral edema within the lateral tibial plateau, which we suspect is degenerative in etiology, but we see no discrete overlying cartilage defect. Articular cartilage of the medial and patellofemoral compartments are intact.LIGAMENTS: Cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: Quadriceps tendon and patellar tendon are intact.ADDITIONAL
Surgical changes of partial lateral meniscectomy with peripheral tear of the lateral meniscal body and other findings as above.
