Right knee pain status post valgus stress. Meniscus versus ligamentous injury. MENISCI: We see no meniscal tear. There is mild irregularity of the posterior medial meniscocapsular structures that we suspect is of no current clinical significance.ARTICULAR CARTILAGE AND BONE: There is a nondisplaced and nondepressed fracture of the lateral aspect of the lateral tibial plateau with the fracture fragment measuring approximately 2 cm in the AP dimension, 1 cm in the medial-lateral dimension, and approximately 7 to 8 mm in depth. There is minimal edema in the medial aspect of the medial tibial plateau. There is edema within the fibular head with somewhat bandlike orientation that conceivably could represent a hairline fracture, but this is equivocal.The articular cartilage of the lateral and medial compartments appears intact. There is heterogeneity of the patellar articular cartilage indicating degeneration with full-thickness degeneration along the lateral facet near the median eminence and superficial delamination along the medial facet.LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
