Acutely, Lateral meniscus tear is likely. Chronically, medial meniscus tear is likely.

During our MSK block, I talked to a resident and a fellow about this topic and they said that medial meniscus tears occur as a long term consequence because of instability of the knee joint. The resident actually had an ACL tear which he did not get repaired so he said that he is almost inevitably going to get a Medial meniscus tear at some point because of joint instability.

Why the lateral meniscus?
Upon lateral stress, the tibia internally rotates and therefore the lateral meniscus rubs up against the lateral condyle of the femur to a greater extent and therefore has a tendency to tear
