Meniscectomy is the surgical removal of all or part of a torn meniscus. A meniscus tear is a common knee joint injury.

This procedure is performed under a general anaesthesia. The choice of type of surgery is based on the size and location of the tear, patient’s age and activity level, surgeon's experience, and individual preferences. In this procedure
- A thin tube (arthroscope) containing a camera and light is inserted through small incisions near the joint.
- Surgical instruments are inserted through other small incisions. Arthroscopic surgery may limit the knee damage from surgery and may promote fuller recovery. But some tears may require open knee surgery.
- In a total meniscectomy: entire meniscus is removed.
- In a partial meniscectomy: 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.
