The menisci are cartilages that sit between the tibia and femur. There is the medial and lateral meniscus. Either one can be torn or damaged with intense physical activity. Most commonly, this happens by a twisting motion. This injury is very common in patients participating in contact sports. Mild injury (Grade I or II) are typically treated with anti-inflammatory medications, rest, and possible physical therapy. More severe injuries (Grade III) typically require a partial or total meniscectomy.
A large incision is made over the knee and the structures of the knee are exposed. The meniscus is examined and either partially or completely removed. The incision is then closed using staples or sutures
