Reason: concern for quad rupture History: pain Evaluation is limited due to the large field of view utilized to evaluate the quadriceps tendon as well as extensive susceptibility artifact within the quadriceps tendon from prior repair.MENISCI: There is truncation of the inner fibers of the posterior horn of the medial meniscus, which may reflect prior meniscectomy or repeat tearing. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is marked thinning of the articular cartilage of the patellofemoral compartment. The bone marrow signal is within normal limits.LIGAMENTS: The posterior collateral and anterior collateral ligaments are intact. The medial collateral ligament and lateral collateral ligament complex are intact. EXTENSOR MECHANISM: Extensive susceptibility artifact within the quadriceps tendon limits evaluation. The tendon appears irregular and thickened with associated intermediate signal intensity which may reflect scarring or tendinosis, and is likely at least partially intact.ADDITIONAL
1.Evaluation of the quadriceps tendon is limited by extensive susceptibility artifact from prior repair; however, the tendon is thickened and irregular, but appears to be at least partially intact.2.Defect in the posterior horn of the medial meniscus may reflect prior meniscectomy or re-tearing.3.Moderate joint effusion.4.Marked thinning of the articular cartilage of the patellofemoral compartment.
