A meniscus tear is among the most common knee injuries, in which forceful twisting or hyper-flexing causes certain tissues in the knee to tear.
Depending on the severity of the injury, symptoms of a torn meniscus include knee pain, swelling, popping, and giving way without warning. Because other knee problems cause similar symptoms, your doctor may order x-rays or MRIs to help confirm the diagnosis.
Treating the injury usually depends on the location of the tear. The outside of the meniscus may heal on its own, with the help of anti-inflammatory medicines and the RICE method (rest, ice, compression, and elevation). If the injury is on the inner 2/3 of the meniscus, surgery may be suggested to repair the damage. In many cases, surgeons often have to remove tissue from the meniscus to do this.
