Right knee pain MENISCI: The posterior horn of the medial meniscus is small and irregular in contour, compatible with multidirectional tearing. The body of the medial meniscus is partially extruded. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is bone marrow edema involving the medial tibial plateau and lateral tibial spine. There is a large area of full-thickness cartilage loss involving the medial femoral condyle measuring up to nearly 2 cm in AP dimension and 5 mm in medial-lateral dimension. There is also a large area of full-thickness cartilage loss involving the medial tibial plateau measuring between 1.5 and 2 cm in AP dimension and 8 mm in medial-lateral dimension. There is mild cartilage thinning involving the lateral tibiofemoral articulation, with a small (3-5 mm) focal full-thickness defect in the lateral femoral condyle. There is diffuse cartilage thinning of the patella without focal defects identified.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Complex tearing of the medial meniscus as above.2.Large areas of full-thickness cartilage loss involving the medial femoral condyle and medial tibial plateau with less severe cartilage loss involving the lateral compartment and patellofemoral articulation as above.
