Key result
Patients with CoC (27%) and MoM (29%) THAs reported more noise than those with MoP THAs (12%), and noisy THAs were associated with significantly worse patient-reported outcome scores.
Why the study?
Do different types of bearings and noise from total hip arthroplasty influence hip-related pain, function, and quality of life postoperatively?
Cross-Sectional (n=3,089)
Yes
Do different types of bearings and noise from total hip arthroplasty influence hip-related pain, function, and quality of life postoperatively?
A high proportion of patients report noise from total hip arthroplasty, which is associated with worse patient-reported outcome scores compared to silent metal-on-polyethylene bearings.

Noise from CoC/MoM THAs was associated with worse PROs; cross-sectional data leaves open whether bearing choice affects long-term outcomes.
Varnum et al. (2016) conducted a cross-sectional in Total hip arthroplasty (n=3,089). Ceramic-on-ceramic (CoC) or metal-on-metal (MoM) THA bearings and THA-related noise vs. Metal-on-polyethylene (MoP) THA bearings and silent THAs was evaluated on Patient-reported outcome measure (PROM) scores and THA-related noise. Patients with CoC (27%) and MoM (29%) THAs reported more noise than those with MoP THAs (12%), and noisy THAs were associated with significantly worse patient-reported outcome scores.
