Cemented femoral stems: what matters most.

Since Charnley hip arthroplasty was introduced to North America over 30 years ago, the popularity of cemented femoral components has waxed and waned. During this time, much has been learned about factors that contribute to cemented stem success and failure. The most important factors that influence arthroplasty success with a cemented femoral stem are patient selection, intramedullary implant geometry, implant surface finish, implant design above the femoral neck resection level, and surgical technique.
