Reason: Evaluate right knee for osteonecrosis, medial femoral condyle History: Medially sided right knee pain MENISCI: Again seen is blunting of the free edge of the medial meniscus. There is now horizontal increased signal intensity extending from the free edge to the periphery, also contacting the tibial articular surface, indicating a horizontal tear. Intrasubstance degeneration of the medial meniscal body. Anterior horn of the medial meniscus appears normal. Lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: Again seen is full-thickness cartilage loss along the weightbearing portion of the medial femoral condyle similar to the prior study with small foci of degenerative subchondral signal abnormality. Mild subjective thinning of the medial tibial plateau articular cartilage. Articular cartilage of the lateral and patellofemoral compartments is intact. No specific findings of osteonecrosis.LIGAMENTS: Anterior cruciate ligament, posterior cruciate, medial collateral ligament, and lateral collateral ligament are intact. EXTENSOR MECHANISM: Patellar and quadriceps tendons are intact. Note is made of a medial patellar plica, which does not appear thickened.ADDITIONAL
Osteoarthritis of the medial tibiofemoral compartment with tear of the posterior horn of the medial meniscus as described above. 3 mm loose body in the posteromedial knee joint. Baker cyst and other findings as described above.
