Abstract
The influence of femoral component surface finish was investigated by comparing 2 finishes, precoat and satin finish, for 1 cemented total hip arthroplasty (THA) system using 1 acetabular cup design. All surgeries were performed by a single surgeon in 2 consecutive series. Minimum 2-year follow-up outcomes (36 precoat, 25 satin) were compared using Harris Hip Scores, radiographs, and survivorships. The precoat population experienced significantly more radiographic and debonding failures than the satin-finish population, and significantly more pain ( P < .05). Comparing failures and nonfailures within the precoat population disclosed neither significant preoperative nor significant cement-grade differences. Because of failure performance of the precoat surface finish, this surgeon no longer implants these components.
