Is It Safe to Have Both Knees Replaced at Once?

Knee replacement surgery is performed on patients with severe knee arthritis, who have failed to find improvement with nonoperative treatments for arthritis. Often knee arthritis is a problem in both of a patient's knees.

Bilateral knee replacement surgery means that both knees are replaced. Patients who have severe knee arthritis in both knees may be good candidates to undergo bilateral total knee replacement.


One concern of bilateral knee replacement is if there is an increased chance of complications from surgery. One complication, having a blood clot, has recently been shown to occur more frequently in patients having both knees replaced in one operation.

Discuss with your doctor if you want to consider bilateral knee replacement.
