19-year-old female patient with history of PCL reconstruction as well as medial and lateral meniscectomies. Evaluate for possible lateral meniscus tear. Metallic susceptibility artifact resulting from multiple screws in the proximal tibia limits evaluation of the proximal tibia and adjacent structures, most notably the medial tibiofemoral compartment.MENISCI: Again seen is intrasubstance abnormal signal intensity within the lateral meniscus that is suggestive of degeneration as well as blunting of the free edge of the posterior horn of the lateral meniscus, which may represent a tear or postsurgical changes from meniscectomy. There is abnormal signal along the undersurface of the anterior horn of the medial meniscus, similar to prior. There is no fluid-filled meniscal tear seen.ARTICULAR CARTILAGE AND BONE: Evaluation of the articular cartilage is limited due to metallic susceptibility artifact. Again seen is a small full-thickness cartilage defect along the anterior margin of the medial femoral condyle with mild underlying bone deformity, suggestive of prior impaction fracture. This appears similar to prior examination. No new fluid-filled cartilage defects.LIGAMENTS: The anterior cruciate ligament is intact. The posterior cruciate ligament graft is intact and is associated with a tunnel and interference screws in the distal femur, compatible with history of prior reconstruction. The medial collateral ligament and lateral collateral ligament complex are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Limited study with stable appearing postoperative changes when compared to prior examination. No new findings to account for patient's pain.
