47-year-old female with history of fall. MENISCI: There is mild intrasubstance degenerative signal within menisci compatible with degeneration, but we see no discrete meniscal tear.ARTICULAR CARTILAGE AND BONE: There is a fracture of the lateral tibial plateau with 1 mm of depression. The fracture fragment is situated beneath the body and posterior horn of the lateral meniscus and measures approximately 1.5 x 1.0 cm in cross-sectional area and 6 mm in depth. There is surrounding bone marrow edema. The fracture plane appears to disrupt the overlying articular cartilage.There is a full-thickness cleft of the articular cartilage along the weight-bearing portion of the medial femoral condyle. There is also a cyst within the intercondylar eminence of the tibia, likely degenerative in etiology. There are foci of full-thickness articular cartilage degeneration of the patella with underlying cyst formation. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is unremarkable.ADDITIONAL
1.Tibial plateau fracture with large joint effusion as described above.2.Cartilage defects as described above.3.No evidence of patellar/quadriceps tendon tear. Other findings as above.
