The Meniscus is a crescent shaped fibrocartilage in the knee that helps distribute load across the joint. It may be injured in sports that involve twisting motions, such as soccer, basketball, and football. Meniscus tears can occur in isolation or in conjunction with other knee injuries such as ligament tears and can range from small, partial tears to complete ruptures. Typically Meniscus injuries result in intermittent pain and catching symptoms in the knee. Occasionally a large meniscus tear may be caught in the knee joint resulting in a “locked knee” that is unable to extend.
