A meniscus tear is damage to one of the rubbery discs that cushion your knee joint. It's sometimes 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 feel better with home care and rehab. Others do better with surgery.
