Knee replacement pain after one year is this normal?

Yes; pain is common: While the goal of knee replacement is pain relief, complete or absolute pain relief is not the norm. Most patients have some degree of discomfort or a reminder that the knee has been replaced even after years; it is seldom felt to be completely "normal." however, more severe pain, after one year, is unusual and probably warrants further evaluation.

Look for other cause: There are many potential sources of knee pain. Hip pain can be referred to the knee. A pinched nerve in the back can cause knee pain. The superficial nerves at round the knee can become sensitized. A physiatrist can help determine the cause and prescribe treatments. Acupuncture and physical therapy can be helpful.
