Reason: quad tendon rupture. Had prior surgery History: right quad tendon pain MENISCI: There is distorted morphology and abnormal signal morphology of the body of the medial meniscus, best seen on coronal proton density fat saturated images, representing complex tearing. This tearing also extends into the posterior horn, which is attenuated and shows increased undersurface signal intensity. The anterior horn of the medial meniscus appears relatively intact. There is also increased signal intensity along the undersurface of the posterior horn of the lateral meniscus, suggesting undersurface fraying/tearing. ARTICULAR CARTILAGE AND BONE: There is moderate osteoarthritis of the knee, particularly affecting the patellofemoral and medial tibiofemoral compartments, with areas of near-full thickness cartilage loss. There is also delamination of the articular cartilage anterior to the posterior horn of the medial meniscus. There are tricompartmental osteophytes. We see no bone marrow edema. LIGAMENTS: Anterior and posterior cruciate ligaments are intact. Medial collateral ligament and lateral collateral complex are intact. EXTENSOR MECHANISM: There are vertically oriented linear bands of abnormal signal within the patella, which likely represent surgical fixation tracts from prior quadriceps tendon repair. The distal quadriceps tendon is thickened with abnormally increased signal intensity, likely representing a combination of tendinosis and scarring, but we see no fluid signal intensity within the tendon to indicate rupture. Small foci of ossification are noted along the tendon, as seen in prior radiographs. There is linear increased signal intensity within the proximal fibers of the patellar tendon laterally, with edema in the adjacent soft tissues, suggesting a focal tear, that extends from the anterior to the posterior margins of the tendon. We see no rupture of the patellar tendon. ADDITIONAL
1.Findings of quadriceps tendon repair with tendinosis and scarring of the quadriceps tendon but no evidence of acute rupture. 2.Focal incomplete tear of the proximal fibers of the patellar tendon. 3.Osteoarthritis with medial and lateral meniscal tears.
