Reason: Evaluate lateral meniscus, s/p lateral menisectomy with continued pain and Baker's cyst, 3 years ago. History: Right knee pain MENISCI: There is blunting of the posterior horn of the lateral meniscus likely representing a combination of degeneration and postsurgical change. No fluid filled tear is identified. The anterior horn appears intact. There is blunting of the free edge of the body of the medial meniscus which likely represents superficial fraying/degenerative tearing. No fluid-filled tear is evident.ARTICULAR CARTILAGE AND BONE: Note is made of focal full-thickness articular cartilage degeneration along the weightbearing portion of the medial femoral condyle above the body of the meniscus measuring approximately 7 mm in the transverse dimension (image 14; series 1001).LIGAMENTS: There is thickening and intermediate signal intensity within the proximal fibers of the PCL which may represent mucoid degeneration or prior tearing. There is cyst formation within the distal femur at the insertion of the PCL. The ACL, MCL and LCL appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Blunting of the medial and lateral menisci as described above likely represents a combination of degeneration and possibly postsurgical change. No fluid-filled tear/unstable tear is identified.2. Focal full-thickness articular cartilage degeneration with delamination along the weightbearing surface of the medial femoral condyle.3. Large Baker's cyst. 4. Thickening and intermediate signal intensity within the proximal fibers of the PCL may reflect prior sprain versus mucoid degeneration.
