Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will be a non-randomized, ambidirectional (retrospective and prospective) study where all subjects will be followed prospectively. The study will evaluate the survivorship of the RAS acetabular component in a previously failed total hip arthroplasty (THA) in a consecutive series of subjects who meet the eligibility criteria.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subject is a candidate for a revision of a failed acetabular component with the Restoration Anatomic Acetabular Shell.
* Subject has signed an IRB-approved, study specific Informed Consent Form (ICF).
* Subject is skeletally mature.
* Subject is a male or non-pregnant female.
* Subject is willing and able to comply with postoperative scheduled clinical evaluations.

Exclusion Criteria

* Subject has a non-Stryker retained stem at the time of study device implantation.
* Subject has a Body Mass Index (BMI) \> 45.
* Subject has an active or suspected latent infection in or about the affected hip joint at time of study device implantation.
* Subject has a mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure, or complications in postoperative care.
* Subject has compromised bone stock which cannot provide adequate support and/or fixation to the prosthesis.
* Subject is diagnosed with a systemic disease (e.g. Lupus Erythematosus) or a metabolic disorder (e.g. Paget's Disease) leading to progressive bone deterioration.
* Subject is immunologically suppressed or receiving steroids in an excess of normal physiological requirements (e.g. \> 30 days).
* Subject has a known sensitivity to device materials.
* Subject is a prisoner.
