Female 47 years old Reason: eval meniscus, patellofemoral joint, prev ACL History: left knee pain MENISCI: The menisci appear intact with only mild intrasubstance degeneration.ARTICULAR CARTILAGE AND BONE: There is focal partial-thickness tearing of the articular cartilage of the medial facet of the patella, similar to prior study. The superior femoral trochlea appears slightly shallow superiorly, perhaps reflecting mild dysplasia, but the clinical significance is of this is uncertain. Articular cartilage of the tibial femoral compartment appears intact.LIGAMENTS: The patient has undergone ACL reconstruction with the graft appearing intact. Small ganglion along the tibial interference screw is of doubtful clinical significance. MCL tear seen previously has healed. LCL and PCL appear normal. There is a subcentimeter focus of low signal intensity along the anterior fibers of the ACL which could reflect focal fibrosis.EXTENSOR MECHANISM: Extensor mechanism is intact.ADDITIONAL
1.Surgical changes of prior ACL reconstruction with graft appearing intact.2.Focal degeneration of articular cartilage of the medial patellar facet.3.Normal appearing menisci; other findings as above.
