Arthroscopic Surgery / The Knee
The menisci are small, semi-circular pieces of cartilage that act as a cushion in the knee. The knee has both an inner and outer meniscus. Treatment varies depending upon the extent and location of the tear; however, a large meniscus tear that causes pain or limits knee function may require arthroscopic surgery for repair. Surgeons often refer to this as "debriding" or "smoothing over" the tear.
