Knee pain, loss of range of motion, difficulty with stairs, joint instability, abnormal knee exam. History of meniscal tear age 12, status post surgery. Assess for meniscal tear. The patient's knee would not fit into the high-definition coil and, therefore, an alternative coil was used resulting in suboptimal image quality.MENISCI: There is extensive deformity of the lateral meniscus with moderate attenuation of the posterior horn and marked attenuation of the body as well as displacement of meniscal tissue into the intercondylar notch indicating a bucket handle tear. Furthermore, there is extensive mucoid degeneration of the anterior horn with formation of intrameniscal cyst that extends anteriorly as a parameniscal cyst is noted. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is heterogeneity of the articular cartilage of the lateral compartment indicating degeneration with near full thickness to full-thickness loss of cartilage above the posterior horn of the lateral meniscus. There there are small subchondral foci of signal abnormality in the lateral femoral condyle presumably degenerative in etiology, as well as a cyst in the lateral tibial spine, which is also presumably degenerative in etiology.LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Deformity and degeneration of the lateral meniscus including a bucket handle tear as described above.2. Degeneration of the cartilage of the lateral femoral compartment.
