Reason: Right knee continued anterior and medial knee pain, s/p patellar microfracture 5/15, evaluate for healing History: Right knee pain MENISCI: Again seen is branching increased signal intensity within the posterior horn of the medial meniscus indicating a complex tear involving the red and red/white zones. There is intermediate signal intensity which extends to the tibial and femoral articular surfaces, however, there is a new fluid-filled defect along the undersurface of the medial meniscus at the junction of the body and posterior horn that indicates a new tear. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is thinning of the articular cartilage of the medial facet of the patella with heterogeneity of the signal intensity of the remainder of the cartilage which likely represents a combination of chondroplasty, degeneration and perhaps immature cartilage secondary to the stated history of prior microfracture. There is a more focal defect along the median eminence that likely represents prior chondroplasty at the site of a prior articular cartilage cleft seen on the prior MRI examination. There is a small focus of poorly defined low signal intensity within the femoral trochlea, centrally, that may represent a small focus of degeneration. There appears to be increased signal intensity of the articular cartilage within the medial tibial plateau underlying the aforementioned medial meniscal tear suggesting focal degeneration. There is a small adjacent osteophyte. The lateral compartment articular cartilage appears intact.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. There is a small amount of fluid within the deep infrapatellar bursa.ADDITIONAL
1. Complex tear of the medial meniscus with new fluid-filled defect along its undersurface.2. Thinning and heterogeneity of the articular cartilage of the medial facet of the patella likely represents a combination of chondroplasty, degeneration and perhaps immature cartilage related to the stated history of prior microfracture.3. Other findings as described above.
