Knee pain MENISCI: There is a bucket-handle tear of the medial meniscus with displacement of meniscal tissue beneath the PCL and along the anterior horn of the medial meniscus. There is additional horizontal signal intensity within the truncated posterior horn of the medial meniscus reflecting additional tearing. The body of the medial meniscus is severely attenuated likely reflecting a combination of tearing/displacement and prior surgical change.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is focal near full-thickness to full-thickness degeneration of the articular cartilage of the lateral femoral trochlea with mild associated subchondral marrow signal abnormality. The remaining articular cartilage of the knee is otherwise intact. The remaining bone marrow signal is normal.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: There is mild increased longitudinal signal within the lateral fibers of the quadriceps tendon which may reflect focal degeneration versus chronic tearing although this may not be of any current clinical significance. The patellar tendon is normal.ADDITIONAL
Re-tear of the medial meniscus with displaced bucket-handle fragment as described above. Referral to the orthopedic surgery service is recommended.
