L knee pain, evaluate for MPFL disruption or other intra-articular pathology, meniscal tear, ACL tear. BONES: The osseous alignment is within normal limits. There is no acute fracture. There is increased bone marrow signal in the lateral femoral condyle compatible with contusion (series 6 image 12).MENISCI: The medial and lateral menisci are normal in morphology and signal.ARTICULAR CARTILAGE AND BONE: Deep fissuring of the medial facet of the patellar cartilage (series 4 image 7), new from prior study. Grade 2/3 chondromalacia of the lateral compartment.LIGAMENTS: The cruciate ligaments and collateral ligaments are unremarkable. There is mildly increased signal on the medial patellofemoral ligament suggestive of sprain (series 4 image 12). The lateral patellofemoral ligament is within normal limits. EXTENSOR MECHANISM: Quadriceps mechanism and patellar ligament are within normal limits.ADDITIONAL
