Noisy Ceramic Hip: Is Component Malpositioning the Problem?

Noisy/squeaking ceramic-on-ceramic (COC) bearing surface is a recently recognized problem associated with total hip arthroplasty (THA). Multiple theories for etiology of this complication have been proposed. Some investigators implicate acetabular component malpositioning as the main potential cause. The intention of this case-controlled study was to evaluate acetabular component positioning in patients with squeaking and nonsqueaking COC THA.
