Reason: 7 months s/p Left knee arthroscopy, microfracture patella, trochlea and medial femoral condyle, continued pain evaluate for healing of microfracture History: left knee pain MENISCI: The lateral meniscus appears intact. There is deformity and increased signal abnormality within the posterior horn of the medial meniscus consistent with a complex tear which extends to involve the body of the meniscus, which is of indeterminate age. The anterior horn appears intactARTICULAR CARTILAGE AND BONE: There is near full-thickness to full-thickness articular cartilage signal abnormality along the weightbearing surface of the medial femoral condyle above the posterior horn of the meniscus which may represent a combination of degeneration and postsurgical changes from prior chondroplasty/microfracture. There are partial-thickness articular cartilage clefts immediately adjacent to this signal abnormality (image 18; series 6).There is subjective thinning of the lateral tibiofemoral articular cartilage. There is moderate to severe articular cartilage degeneration affecting the patellofemoral compartment with a focal area of the median eminence of the patella being completely devoid of articular cartilage. There is a linear focus of increased and decreased signal abnormality within the femoral trochlea, centrally, indicating a full-thickness articular cartilage cleft. There is full-thickness articular cartilage signal abnormality along the medial facet of the patella which likely represents a combination of degeneration and postsurgical change from prior chondroplasty/microfracture. There is subchondral signal abnormality in the surrounding area.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Complex tear of the posterior horn of the medial meniscus.2. Articular cartilage signal abnormality along the medial femoral condyle and medial facet of the patella as described above which likely represents a combination of degeneration as well as postsurgical change related to prior chondroplasty/microfracture as described above.
