Reason: evaluate for ligament injury History: L knee pain Severely limited examination secondary to patient motion artifact. The examination was terminated early due to the patient's inability to tolerate the examination. Due to the patient's body habitus, the dedicated knee coil could not be utilized. A flex coil was utilized instead resulting in suboptimal image quality.MENISCI: Limited evaluation of the menisci due to the aforementioned motion artifact. The lateral meniscus is grossly intact. There is deformity, blunting and increased signal abnormality affecting the posterior horn and body of the medial meniscus indicating complex degenerative tearing.ARTICULAR CARTILAGE AND BONE: There is increased bone marrow signal abnormality within the medial femoral condyle and medial aspect of the tibial plateau which may be degenerative in etiology. There is full-thickness articular cartilage degeneration along the medial tibiofemoral compartment with large areas completely devoid of articular cartilage. There are tricompartmental osteophytes. There is subjective thinning of the lateral compartment articular cartilage. Evaluation of the patellofemoral articulation is limited due to the lack of axial imaging.LIGAMENTS: The cruciate and collateral ligaments appear grossly intact within the limitations of this examination. There is increased signal abnormality within the proximal fibers of the superficial band of the MCL which may represent a mild sprain injury in the correct clinical context.EXTENSOR MECHANISM: The extensor mechanism appears intact. There is thickening and intermediate signal intensity within the distal fibers of the patellar tendon indicating moderate tendinosis.ADDITIONAL
1. Limited examination. Osteoarthritis of the knee including full-thickness articular cartilage degeneration most pronounced along the medial tibiofemoral compartment. There is degeneration and complex degenerative tearing of the medial meniscus.2. Bone marrow signal abnormality within the medial femoral condyle and medial tibial plateau is likely degenerative in etiology although bone contusions could be considered in the correct clinical context.3. Findings indicating a mild sprain of the superficial band of the MCL as described above.4. Large joint effusion.
