Isolated Polyethylene Exchange in a Second Generation Cementless Acetabular Component

Some have suggested that isolated polyethylene exchange in a well-fixed Harris-Galante II acetabular component (Zimmer, USA) necessitates cementing the liner or revision of the entire component, as the locking mechanism is suboptimal. The purpose of this study was to review the minimum two-year results of polyethylene exchange using the native locking mechanism in the HGP-II acetabular design.
