Reason: knee pain, unable to bear weight/ambulate History: as above MENISCI: There is globular increased signal abnormality within the posterior horn of the lateral meniscus indicating intrasubstance degeneration. There is a small radial tear of the posterior horn of the lateral meniscus with a flipped meniscal fragment situated medial to the body of the meniscus (coronal image 19: series 9). Some of the signal extends to the tibial and femoral articular surface consistent with superficial fraying and degenerative tearing. There is globular increased signal abnormality within the posterior horn of the medial meniscus consistent with intrasubstance degeneration. No fluid-filled tear is evident.ARTICULAR CARTILAGE AND BONE: There are tricompartmental osteophytes. There is near full-thickness to full-thickness articular cartilage degeneration along the medial tibial femoral compartment. There is relative sparing of the lateral tibiofemoral compartment. There is decreased signal abnormality within the articular cartilage along the weightbearing surface of the lateral femoral condyle likely representing chondrocalcinosis. There is full-thickness articular cartilage degeneration along the patellofemoral articulation with large areas of the lateral facet of the patella and femoral trochlea completely devoid of articular cartilage with underlying subchondral signal abnormality, likely degenerative in etiology. There is near full-thickness to full-thickness articular cartilage degeneration along the medial facet of the femoral trochlea and patella.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Severe degenerative changes affecting the right knee most pronounced along the patellofemoral articulation with findings suggesting CPPD arthropathy.2. Radial tear of the posterior horn lateral meniscus with a small flipped meniscal fragment as well as intrasubstance degeneration as described above.
