Periprosthetic bone mineral density and fixation of the uncemented CLS stem related to different weight bearing regimes

摘要

Background and purposeThere is no consensus on the best rehabilitation regime after uncemented total hip arthroplasty. Theoretically, bone ingrowth into the implant should benefit from initial partial weight bearing. We investigated whether the degree of postoperative weight bearing influences the periprosthetic bone mineral density (BMD) and/or the stability of the CLS stem.
