Reason: Right knee pain evaluate for meniscus tear vs chondral injury History: Right knee pain MENISCI: There is linear increased signal abnormality within the posterior horn of the medial meniscus which extends to the tibial and femoral articular surfaces consistent with a small radial tear. There is increased signal abnormality within the anterior horn of the medial meniscus which extends to the tibial and femoral articular surfaces consistent with a longitudinal tear. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: The lateral tibiofemoral articular cartilage appears intact. There is near full-thickness to full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle and medial tibial plateau about the body and anterior horn of the meniscus. There is underlying degenerative subchondral signal abnormality. There is near full-thickness to full-thickness articular cartilage degeneration along the medial facet of the patella which may represent a combination of chondroplasty, degeneration and microfracture. There is subchondral cyst formation and degenerative subchondral signal abnormality in the surrounding area. There is a small amount of low signal intensity within this defect which could conceivably represent a small amount of fibrocartilage formation related to the patient's history of microfracture. These findings appear similar to the prior study. There is a partial-thickness articular cartilage fissure along the median eminence and lateral facet of the patella.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Tearing of the medial meniscus as described.2. Osteoarthritis of the right knee with near full-thickness to full-thickness articular cartilage degeneration and articular cartilage clefts as described above.3. Focal near full-thickness to full-thickness articular cartilage defect along the medial facet of the patella may represent a combination of prior chondroplasty, degeneration, and microfracture, which appears similar to the prior study.4. Patella alta.
