Reason: eval microfrx healing History: pain MENISCI: There is blunting and deformity of the posterior horn of the medial meniscus which likely represents a combination of postsurgical changes from prior partial meniscectomy, degeneration, and prior tearing, appearing similar to the prior study. No fluid-filled defect is identified to suggest a new tear. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage of the lateral compartment appears intact. There is near full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle posteriorly above the posterior horn of the meniscus with underlying subchondral signal abnormality. There is near full-thickness articular cartilage degeneration along the lateral facet of the patella which may have progressed slightly when compared to the prior exam. There is low signal intensity material identified along the lateral facet of the patella likely representing fibrocartilage related to prior microfracture, appearing similar to the prior study. There is subchondral edema in the surrounding area.LIGAMENTS: The cruciate and collateral ligaments appear intact. There is a subcentimeter focus of fluid signal intensity along the posterior aspect of the PCL which may represent mucoid degeneration versus ganglion formation.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Blunting and deformity of the posterior horn of the medial meniscus, appearing similar to the prior study, likely representing a combination of postsurgical changes from prior partial meniscectomy, degeneration, and prior tearing. No new fluid-filled tear is identified.2. Slight interval progression of articular cartilage degeneration affecting the patellofemoral articulation with postsurgical changes consistent with the stated history of prior microfracture.
