Reason: evaluate for medial meniscus and acl tears History: pain, effusion, clicking. Metallic artifact within the proximal tibia related to bullet fragments.MENISCI: Complete loss of the anterior body and horn of the lateral meniscus. The posterior horn of the lateral meniscus is intact.Globular intrasubstance signal involving the undersurface of the anterior body and the free edge of the anterior horn of the medial meniscus likely due to degeneration overlying the prior tibial plateau fracture.ARTICULAR CARTILAGE AND BONE: Thinning of the articular cartilage anteriorly along the medial tibiofemoral compartment. Near complete loss of articular cartilage anteriorly along the lateral tibiofemoral compartment. Deformity and postsurgical changes of the proximal tibia compatible with prior tibial plateau fracture.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Complete loss of the anterior body and anterior horn of the lateral meniscus. Degeneration of the undersurface of the anterior body and anterior horn of the medial meniscus. Associated cartilage loss. These findings likely are related to patient's prior tibial plateau fracture.
