Treatment
How your orthopedic surgeon treats your tear will depend on the type of tear you have, its size, and location.
The outside one-third of the meniscus has a rich blood supply. A tear in this “red” zone may heal on its own, or can often be repaired with surgery. A longitudinal tear is an example of this kind of tear.
In contrast, the inner two-thirds of the meniscus lacks a blood supply. Without nutrients from blood, tears in this “white” zone cannot heal. These complex tears are often in thin, worn cartilage. Because the pieces cannot grow back together, tears in this zone are usually surgically trimmed away.
Along with the type of tear you have, your age, activity level, and any related injuries will factor into your treatment plan.
Nonsurgical Treatment
If your tear is small and on the outer edge of the meniscus, it may not require surgical repair. As long as your symptoms do not persist and your knee is stable, nonsurgical treatment may be all you need.
RICE. The RICE protocol is effective for most sports-related injuries. RICE stands for Rest, Ice, Compression, and Elevation.
Rest. Take a break from the activity that caused the injury. Your doctor may recommend that you use crutches to avoid putting weight on your leg.
Ice. Use cold packs for 20 minutes at a time, several times a day. Do not apply ice directly to the skin.
Compression. To prevent additional swelling and blood loss, wear an elastic compression bandage.
Elevation. To reduce swelling, recline when you rest, and put your leg up higher than your heart.
Non-steroidal anti-inflammatory medicines. Drugs like aspirin and ibuprofen reduce pain and swelling.
Surgical Treatment
If your symptoms persist with nonsurgical treatment, your doctor may suggest arthroscopic surgery.
Knee arthroscopy. In this procedure a miniature camera is inserted through a small incision. This provides a clear view of the inside of the knee. Your orthopedic surgeon inserts miniature surgical instruments through other small incisions to trim or repair the tear.
Meniscectomy. In this procedure, the damaged meniscal tissue is trimmed away.
Meniscus repair. Some meniscal tears can be repaired by suturing (stitching) the torn pieces together. Whether a tear can be successfully treated with repair depends upon the type of tear, as well as the overall condition of the injured meniscus. Because the meniscus must heal back together, recovery time for a repair is much longer than from a meniscectomy.
