Knee pain. Lateral joint space pathology versus patellar tendinitis. MENISCI: The anterior horn of the lateral meniscus appears abnormally small with heterogeneous signal representing degeneration and tearing. The tearing extends into the body of the lateral meniscus, and there appears to be a shallow defect of the undersurface of the anterior half of the meniscal body. Increased signal intensity along the undersurface of the inner fibers of the posterior horn of the lateral meniscus likely represents additional fraying/degenerative tearing.There is increased signal intensity within the undersurface of the inner third of the body and posterior horn of the medial meniscus likely representing fraying/degenerative tearing. The anterior horn of the medial meniscus appears intactARTICULAR CARTILAGE AND BONE: There is full-thickness degeneration of the articular cartilage of the lateral tibial plateau beneath and anterior to the posterior horn of the lateral meniscus. There is also full-thickness degeneration of the articular cartilage of the weightbearing portion of the medial tibial plateau between the anterior and posterior meniscal horns with a small amount of underlying degenerative subchondral signal abnormality.. There is focal full-thickness degeneration of the articular cartilage of the patella centrally with underlying subchondral cyst formation. Additional superficial fraying is noted along the articular cartilage of the medial and lateral facets. The articular cartilage of the femoral trochlea appears relatively intact, although the trochlea itself subjectively appears shallow which may reflect dysplasia. There are small tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact EXTENSOR MECHANISM: There is slight thickening of the patellar tendon with intermediate signal intensity at its proximal and distal attachment suggesting mild tendinosis. The quadriceps tendon appears intact.ADDITIONAL
