Reason: Evaluate for quadriceps tendon rupture History: left knee pain, swelling, inability to actively extend MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage is grossly intact. No fractures are present.LIGAMENTS: The ACL, PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: There is a high-grade complete tear through the superficial fibers of the rectus femoris and vastus medialis tendons with approximately 1.8 cm of retraction of the torn fibers. Posteriorly, the deep fascial layers of the vastus intermedius and lateralis remain intact. The patellar tendon is intact.ADDITIONAL
Near full-thickness tear of the quadriceps tendon with a large subcutaneous and intra-articular hematoma.
