What this trial studies

This observational study aims to assess the safety and effectiveness of the Signature Orthopaedics Spartan Stem, World Acetabular Cup, and World Liner in patients undergoing primary total hip arthroplasty. Data will be collected at various stages, including pre-operative, operative, discharge, and one year post-operative evaluations, focusing on the revision rate and patient-reported outcomes. The study will also analyze radiographic data to evaluate the bony response to the implants and the effectiveness of cementless fixation over a two-year follow-up period.

Who should consider this trial

Good fit: Ideal candidates are males and non-pregnant females aged 18-75 requiring unilateral primary total hip arthroplasty due to non-inflammatory degenerative joint disease.

Not a fit: Patients with active infections, inadequate bone stock, known metal sensitivities, or those who are immuno-suppressed may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of hip replacement device performance, leading to improved patient outcomes.

How similar studies have performed: Other studies have shown success in monitoring hip replacement devices, indicating that this approach is supported by previous findings.
