What can you tell me about meniscus tears?
A meniscus tear is a common knee injury. Meniscal cartilage is a wedge-like rubbery cushion that curves like the letter "C' at the inside and outside of the knee. Each knee joint has two menisci (plural for "meniscus"). This cartilage helps stabilize the knee joint and provides cushioning between the thighbone (femur) and shinbone (tibia).
A meniscus tear can result from any activity that produces a twisting or rotational stress to the knee — such as aggressive pivoting or sudden stops and turns. In older adults, a meniscus tear can occur from degenerative changes of the knee.
Signs and symptoms of a meniscus tear can include:
Treatment of a meniscus tear may include:
In some cases, a flap of the torn cartilage can interfere with knee movement and cause "locking" of the knee joint. Arthroscopic surgery may be needed to trim the torn flap and restore normal joint movement. In some cases, especially in younger individuals, it may be possible to repair the tear using arthroscopic surgery.
