Knee pain is a common complaint that affects people of all ages. Knee pain may be the result of an injury, such as a ruptured ligament or torn cartilage. Medical conditions — including arthritis, gout and infections — also can cause knee pain.

Over-the-counter medications — such as acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin, others) and naproxen (Aleve, others) — may help ease knee pain.
