What this trial studies

This observational study aims to collect data on the safety and performance of the Everglade Stem, World Acetabular Cup, and World Liner used in primary total hip arthroplasty. It involves a prospective follow-up of patients at various time points, including pre-operative, discharge, one year, and two years post-operative evaluations. The primary objective is to monitor the revision rate of the implants and assess patient satisfaction through the Oxford Hip Score, alongside radiographic analysis to evaluate the effectiveness of cementless fixation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 requiring unilateral primary total hip arthroplasty due to non-inflammatory degenerative joint diseases.

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 provide valuable insights into the long-term safety and effectiveness of these hip implants, potentially improving patient outcomes.

How similar studies have performed: Other studies on post-market clinical follow-up of orthopedic implants have shown success in confirming safety and performance, making this approach well-supported.
