After many years of wear and tear, knee pain often becomes more common as we get older. Most knee pain in people over 50, unless caused by a sudden injury, is due to osteoarthritis — a gradual thinning of cartilage within the knee joint. Cartilage allows the bones to smoothly glide across each other. As the cartilage layer thins or becomes pock-mocked, the joint surface can become inflamed from the friction, leading to stiffness and pain.
But when time, rest, physical therapy or anti-inflammatory medicines don’t help relieve chronic pain, injectable therapy might be the next step.
