63-year-old female patient with pain in right knee. Question of right knee chondromalacia. MENISCI: There is increased signal within the posterior horn of the medial meniscus. Additionally, there is linear increased T2 signal within the body of the medial meniscus which may represent a horizontal cleavage tear (image 19, series 1301). The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is partial-thickness loss of the cartilage of the weightbearing portion of the medial femoral condyle. There are partial-thickness defects of the lateral and medial facets of the patella with a full-thickness fissure more superiorly within the medial facet with T2 signal abnormality within the underlying bone. There is mild thinning of the weightbearing portion of the articular cartilage of the lateral femoral condyle.A subcentimeter lesion within the proximal tibia with high T2 signal likely represents a benign enchondroma.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Chondromalacia of the right knee, most predominantly affecting the medial tibiofemoral compartment.2. Questioned horizontal cleavage tear of the body of the medial meniscus.
