Reason: right knee pain History: right knee pain MENISCI: There is blunting of the posterior horn of the lateral meniscus indicating a new longitudinal tear although some of this may in part reflect postsurgical change from prior partial meniscectomy. There is blunting and deformity of the posterior horn of the medial meniscus likely representing a combination of prior complex tearing, postsurgical change and degeneration which extends to involve the body of the meniscus. There is a ghost meniscus affecting the posterior horn of the medial meniscus near its root indicating a full-thickness radial tear.ARTICULAR CARTILAGE AND BONE: There is a focal full-thickness articular cartilage defect along the weightbearing surface of the medial femoral condyle measuring approximately 1.5 cm in the AP dimension. There is a focal full-thickness articular cartilage defect along the femoral trochlea centrally, which extends along the lateral facet, measuring approximately 13 mm in the craniocaudal dimension.LIGAMENTS: Note is made of postsurgical changes of prior ACL graft reconstruction. The graft appears intact. The PCL appears intact. The MCL and LCL appear intact EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Postsurgical change of prior ACL graft reconstruction. The graft appears intact.2. Radial tear of the posterior horn of the medial meniscus near its root, new from prior examination. There is also blunting and deformity of the posterior horn of the medial meniscus which likely represents a combination of prior complex tearing, postsurgical change and degeneration.3. Tearing of the posterior horn of the lateral meniscus which also appears new from the prior examination.4. Focal full-thickness articular cartilage defects along the femoral trochlea and medial femoral condyle which are new when compared to the prior examination.
