The next generation of acetabular shell design and bearing surfaces.
The R3 Acetabular component represents the next generation of acetabular shell with an enhanced porous ingrowth surface (StikTite, Smith & Nephew, Memphis, Tenn) to meet the needs of both primary and revision hip arthroplasty; an optimized locking mechanism; and the ability to accomodate polyethylene, metal, or ceramic liners. This prospective clinical study reports on the safety and efficacy of the new StikTite porous ingrowth surface using radiostereometric analysis (RSA). StikTite provides a superior "sctratch-fit" due to its greater coefficient of friction and less micromotion using RSA measurements.
