A meniscus tear is damage to one of the rubbery discs that cushion your knee joint. It's usually caused by twisting your knee while your foot stays planted on the ground. It can be painful and keep your knee from working right.
Some tears will heal with rest and physical therapy. Others need to be repaired with surgery.
