what caused my knee degeneration
Osteoarthritis (OA) is a form of degenerative joint pain caused by wear and tear on your joints. As you age, the cartilage that cushions your joints starts to wear down, causing the bones to rub together. The bone-on-bone action leads to inflammation of the joints. Osteoarthritis most commonly affects the joints in your arms and legs, including your fingers, wrists, knees, ankles, and hips. The lower back is also a common source of OA pain. Let your doctor know if youâre suffering from the early symptoms of osteoarthritis.
