Medial knee pain MENISCI: There is horizontal linear signal across the lateral meniscus involving the posterior horn and body (sagittal series 7 image 23/28) which extends to the superior articular surface. There is globular signal within the posterior horn of the medial meniscus without extension to the articular surface however there is truncation of the body and anterior horn of the medial meniscus suspicious for tearing.ARTICULAR CARTILAGE AND BONE: There is heterogeneous signal intensity of the articular cartilage of the lateral compartment of both the tibial plateau and femoral condyle. There is no full-thickness cartilage defect however. Similar moderate articular cartilage thinning is noted in the medial compartment particularly of the femoral condyle with near full-thickness loss anteriorly. There is marked articular cartilage loss of the patellar facet, lateral greater than medial. Heterogeneous signal of the femoral trochlea is also noted. Degenerative cystic changes noted in the lateral tibial plateau.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Horizontal tearing of the lateral meniscus with findings suspicious for radial tear of the body and anterior horn of the medial meniscus.2. Severe patellofemoral articular cartilage loss with more moderate changes noted in the medial and lateral compartments.3. Moderate suprapatellar effusion.
