A Review of Squeaking in Total Hip Arthroplasty

Squeaking in ceramic-on-ceramic total hip replacements is a well-documented phenomenon. It is usually a benign complication, well tolerated by patients. Only rarely, it is a cause for revision surgery. The etiology of squeaking is less well understood, but clearly it has a multifactorial origin. We investigated demographic and implant position factors associated with squeaking hips, and following a series of studies on the mechanisms of noise production in this group of implants, we propose a mechanism by which the sound is generated.
