Meniscus tears

A medial meniscus injury is caused by simultaneous abduction of the knee and internal rotation of the femur. A lateral meniscus injury is caused by simultaneous adduction of the knee and external rotation of the femur. Knee pain appears at the time of injury, swelling appears within a couple of hours, and the knee may also lock immediately. The diagnosis is confirmed by arthroscopy, magnetic resonance imaging. Mild symptoms require only follow-up, exercise of the quadriceps muscle, and NSAIDs for pain relief. Partial arthroscopic excision of the injured meniscus or suturing the ruptured meniscus either arthroscopically or during open surgery is done.
