Meniscectomy is the surgical removal of all or part of a torn meniscus. A meniscus tear is a common knee joint injury. Surgeons who perform meniscectomies (orthopedic surgeons) will make surgical decisions based on the meniscus's ability to heal as well as your age, health, and activity level. In a total meniscectomy, the entire meniscus is removed. In a partial meniscectomy, the surgeon removes as little of the meniscus as possible. Unstable meniscal fragments are removed, and the remaining meniscus edges are smoothed so that there are no frayed ends.
