Reason: pain, concern for meniscus and LCL History: pain MENISCI: There is linear increased signal abnormality within the posterior horn of the lateral meniscus which extends to the tibial articular surface indicating a longitudinal tear. The anterior horn appears intact. The medial meniscus appears intactARTICULAR CARTILAGE AND BONE: There is a focal full-thickness articular cartilage defect along the lateral facet of the femoral trochlea with underlying degenerative subchondral signal abnormality (image 13; series 501). This defect extends to involve the femoral trochlea centrally and a small portion of the medial facet of the femoral trochlea as well.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Longitudinal tear of the posterior horn of the lateral meniscus.2. Focal full-thickness articular cartilage defects along the femoral trochlea as described above. Other findings as described.
