After a total knee replacement (TKR) for a bad knee, I started walking with a limp and a “squeak.” Every time I bend my knee it creaks and squeaks. What could be causing this?

Patients who report squeaking, creaking, and other noise after a TKR may have a problem with the kneecap. The physician can diagnose this. An exam and X-ray will be needed.

Failure of the kneecap isn’t an uncommon problem. The backing can wear away and the pegs that hold it in place can break. Sometimes the plastic lining pulls away. A second operation to repair or revise this problem may be advised.
