Meniscectomy is an operative procedure, nowadays done arthroscopically, that involves trimming or removing the unstable torn portion of the cartilage, with the goal of eliminating or minimizing symptoms. This is done as an outpatient arthroscopic procedure, usually under local anesthesia. It is unusual to need a general anesthetic for this problem. It is typically done through several small puncture wounds called portals, that facilitate use of the arthroscope and specific instruments designed to trim and smooth out the torn cartilage segments. Additional arthroscopic procedures can be performed at the same time, if indicated and necessary.
Rehabilitation is rapid and can often be performed at home with minimal equipment.
Early exercises include wiggling the toes and pumping the ankle up and down, and squeezing the thigh muscles for 6 to 8 second. Straight leg raises are also advisable for the first several days post-operatively, while either sitting or lying down, again, holding the leg about 40 degrees elevated for about 6 to 8 seconds at a time. At 3 to 5 days post-operatively, use of a stationery bike, Nordic Track or stair master may also be helpful, with low resistance. At 5 to 7 days resistance is gradually increased in a progressive fashion. Crutches are typically not necessary, nor is a splint or brace.
