Meniscus tear status post ACL reconstruction 2003 with BTB. Medial joint line tenderness and progressive pain over several years. MENISCI: There is a horizontal tear through the posterior horn and body of the medial meniscus extending to the tibial articular surface with additional vertical component best appreciated on series 801, image 19. Postoperative findings of partial medial meniscectomy are present. Intermediate signal in the posterior horn of the lateral meniscus may indicate some intrasubstance degeneration though no discrete tear of the lateral meniscus is appreciated.ARTICULAR CARTILAGE AND BONE: There is grade II to III chondromalacia of the weightbearing portion of the medial femoral condyle, with a superimposed more focal area of increased signal suggestive of fraying (series 601, image 13). Low signal intensity in portions of the articular cartilage of the medial condyle may relate to microfracture changes. Otherwise cartilage of the lateral femoral condyle and patellofemoral compartment is intact. Tibial tunnel of the ACL graft reconstruction is noted. No significant bone marrow signal abnormality is present.LIGAMENTS: ACL graft reconstruction is present without evidence of complication. The posterior cruciate ligament, collateral ligaments, and popliteal ligaments are intact.EXTENSOR MECHANISM: Extensor mechanism is intact.ADDITIONAL
1.Post surgical findings related to ACL graft reconstruction, medial meniscectomy, and microfracturing of the medial femoral condyle.2.Multidirectional tear of the medial meniscus, as above.
