Eligibility Criteria
You may qualify if:
- Patient has signed an IRB/EC approved, study specific Informed Patient Consent Form.
- Patient is a male or non-pregnant female, skeletally mature and age 18-75 years at time of study device implantation.
- Patient has a diagnosis of Non-Inflammatory Degenerative Joint Disease (NIDJD).
- Patient is a candidate for a primary cementless acetabular replacement.
- Patient is willing and able to comply with postoperative scheduled clinical and radiographic evaluations and rehabilitation.
You may not qualify if:
- Patient has a Body Mass Index (BMI) ≥ 40.
- Patient has an active or suspected latent infection in or about the affected hip joint at time of study device implantation.
- Patient has a neuromuscular or neurosensory deficiency, which limits the ability to evaluate the safety and efficacy of the device.
- Patient is diagnosed with a systemic disease (e.g. Lupus Erythematosus) or a metabolic disorder (e.g. Paget's disease) leading to progressive bone deterioration.
- Patient is immunologically suppressed or receiving steroids in excess of normal physiological requirements (e.g. \> 30 days).
- Patient requires revision surgery of a previously implanted total hip replacement or hip fusion to the affected joint.
- Patient has a known sensitivity to device materials.
- Patient is a prisoner.

Limitations and Caveats
Due to circumstances starting with the COVID-19 pandemic and challenges recalling study subjects for long term postoperative visits, the follow-up compliance decreased significantly. Therefore, there would be inadequate subjects to analyze at the 10 year endpoint. For this reason, a business decision was made to close the study early.
