Arms Assigned Interventions
Active Comparator: A
ASR™-XL Modular Acetabular Cup System stem
Device: ASR™-XL Modular Acetabular Cup System
The ASR™-XL Modular Acetabular Cup System treatment device is comprised of a metal acetabular cup, a unipolar femoral head and a taper sleeve adapter.
Other Name: Acetabular cup replacement
Active Comparator: B
Pinnacle™ acetabular shell, with a 28mm or 36mm ULTAMET® metal liner, and a 28mm or 36mm Articul/eze M head.
Device: Pinnacle™ acetabular shell
The Pinnacle™ shells are cementless, titanium alloy cups with Porocoat® porous coating and HA DuoFix™ coating. There are various different liners available for use with the Pinnacle™ Acetabular Cup System. For the purpose of this investigation, the CoCrMo ULTAMET® 28mm or 36 mm metal liners will be used.
Other Name: Acetabular cup replacement

Detailed Description:

The purpose of this clinical investigation is to gather sufficient clinical and radiographic data to permit valid scientific comparisons between treatment and control group outcomes. The treatment group/device for this study is the ASR™-XL Acetabular Cup System, and the control group/device is the Pinnacle™ Cup System w/ the 28mm or 36mm ULTAMET™ metal liner. The study objective will be achieved by way of treatment group selection, treatment administration, and management of participating study Subjects.
