Status post left knee arthroscopy with continued pain, evaluate for patellofemoral chondromalacia or medial meniscus tear MENISCI: There is increased signal intensity within the superior fibers of the posterior horn of the medial meniscus at/near its root, which is new from the prior study. While this finding is compatible with a tear, it is conceivable that this could represent postoperative changes from prior meniscal repair or debridement. The remaining medial meniscus is unremarkable. The lateral meniscus is normal.ARTICULAR CARTILAGE AND BONE: There is a small focus of increased signal intensity seen only on the fat-suppressed proton density axial sequence traversing the articular cartilage of the median eminence of the patella which may represent a small non-fluid-filled cleft. This location is similar to that of the fissure described on the prior study. There is abnormal signal intensity within the subchondral marrow of the lateral aspect of the medial femoral condyle likely representing the site of microfracture. Increased signal intensity in the overlying articular cartilage may represent a residual cartilage defect. The lateral compartment is unremarkable.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Small focus of signal abnormality in the patellar cartilage as described above may represent a non-fluid filled cleft.2.Signal abnormality in the medial femoral condyle likely due to microfracture. Increased signal intensity in the overlying cartilage may represent a residual cartilage defect.3.Abnormal signal in the posterior horn of the medial meniscus near its root is compatible with a tear, but could also represent postoperative changes.
