Description
Summary:Selection of an acetabular component for total hip arthroplasty that can achieve initial stability and then remain stable for long-term fixation to occur requires specific implant design features. In this work, the authors describe the stages of implant fixation for cemented and cementless components, identify the key design characteristics of an acetabular component that will ensure stability as bone remodeling or osseointegration occurs, and review the clinical results of various cup designs. The authors recommend an acetabular component that offers good initial fixation, limits migration during the intermediate stage, provides a mechanism for osseointegration, and resists tensile loads.
