57-year-old female with left knee pain. Evaluate for left knee lateral meniscus re-tear. MENISCI: There is deformity and blunting of the body and posterior horn of the lateral meniscus. Additionally there is increased signal abnormality which extends to the femoral articular surface which presumably represents the sequela of a prior tearing and postsurgical changes from prior partial meniscectomy. No fluid-filled defects are identified to suggest an unstable tear/re-tear of the meniscus. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness articular cartilage degeneration along the posterior aspect of the lateral femoral condyle and posterior aspect of the lateral tibial plateau with associated underlying subchondral signal abnormality. There is thinning of the articular cartilage of the medial compartment. There is focal near full-thickness articular cartilage degeneration along the weightbearing portion of the medial femoral condyle overlying the anterior horn of the meniscus. There is focal near full thickness articular cartilage degeneration along the lateral facet of the patella. There is perhaps mild dysplasia of the medial facet of the trochlea.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Findings consistent with prior tearing and post surgical changes of the lateral meniscus without fluid filled defects to confirm a re-tear as clinically questioned.
