33-year-old female with knee instability, rule out ACL and medial meniscal tear MENISCI: There is a buckle handle tear of the medial meniscus with meniscal tissue displaced into the intracondylar notch, anterior to the PCL. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: We see no bone contusions. We see no fluid-filled articular cartilage defects.LIGAMENTS: The ACL appears disrupted at its femoral attachment which presumably represents a chronic tear given the lack of bone contusions. Additional ligaments appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
ACL tear and bucket-handle tear of the medial meniscus. These may be chronic given the lack of bone contusions.
