Reason: right knee pain History: same MENISCI: There is blunting of the posterior horn of the lateral meniscus with associated linear signal abnormality that extends to the tibial articular surface indicating a horizontal tear (image 8; series 5). The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage of the lateral tibiofemoral compartment appears intact. There is blistering of the articular cartilage along the anterior aspect of the weightbearing surface of the medial femoral condyle. There is a linear focus of low signal intensity within the femoral trochlear articular cartilage, centrally, likely representing a full-thickness articular cartilage cleft (image 16; series 7). There is also a near full-thickness articular cartilage cleft along the medial facet of the patella with surrounding articular cartilage degeneration. There are small tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. There is mild increased signal abnormality within the proximal fibers of the patellar tendon which may represent a very mild patellar tendinosis.ADDITIONAL
1. Horizontal tear of the lateral meniscus.2. Articular cartilage degeneration and full-thickness articular cartilage clefts most severely affecting the patellofemoral articulation.3. Edema interposed between the lateral femoral condyle and iliotibial band is nonspecific, but can be seen in patients with iliotibial band friction syndrome, particularly in an avid runner.4. Mild tendinosis of the patellar tendon.
