Short-term Outcomes With a Second-Generation Uncemented Stem in Total Hip Arthroplasty.

An uncemented stem has been used successfully in total hip arthroplasty for 2 decades, and some implants have been updated. The authors have used second-generation uncemented proximal porous coating stems, the Echo Bi-Metric Full Proximal Profile stem (Echo FPP; Biomet, Warsaw, Indiana) and the Echo Reduced Proximal Profile stem (Echo RPP; Biomet). This article reports short-term outcomes with these stems compared with their predecessor, the Bi-Metric stem (Biomet).
