Reason: Assess for medial meniscal tear; patient is s/p R medial and lateral partial meniscectomies in 11/2013 History: R knee pain, locking symptoms MENISCI: There is blunting of the posterior horn of the medial meniscus as well as irregularity of the undersurface of the posterior horn which extends to involve the body of the meniscus. The anterior horn appears intact. There is globular increased signal abnormality within the anterior horn of the lateral meniscus indicating intrasubstance degeneration. There is blunting of the anterior and posterior horn of the meniscus. No fluid-filled tear is evident.ARTICULAR CARTILAGE AND BONE: Note is made of full-thickness articular cartilage degeneration along the weightbearing portion of the lateral femoral condyle and lateral tibial plateau with underlying subchondral cyst formation within the lateral tibial plateau. There is a full-thickness articular cartilage cleft along the posterior aspect of the lateral tibial plateau (image 11; series 4). There is near full-thickness to full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle and medial tibial plateau. There is near full-thickness to full-thickness articular cartilage degeneration affecting the patellofemoral articulation. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Osteoarthritis of the right knee including tricompartmental full-thickness articular cartilage degeneration as well as an articular cartilage cleft as described above.2. Blunting of the medial and lateral meniscus which likely represents a combination of degeneration, tearing and postsurgical change from prior partial meniscectomy. No fluid-filled tear is evident to confirm a new tear.
