Everglade Stem, World Cup and World Liner Post Market Clinical Follow-up

Recruiting

• Conditions: Hip Disease

• Registration Number: NCT06153940
• Lead Sponsor: Signature Orthopaedics

Brief Summary

The aim of the Study is to monitor the performance of the Signature Orthopaedics Everglade Stem, World Acetabular Cup and World Liner as a part of post-market vigilance and continuous improvement efforts.

Detailed Description

The Objective of this Post market Clinical Follow up (PMCF) study is to collect data confirming safety, performance and clinical benefits of the Everglade Stem, World Acetabular Cup and World Liner when used for a primary total hip arthroplasty at 2 years follow-up.

This prospective follow-up series is necessary to gather data for the Everglade Stem, World Acetabular Cup and World Liner as they are recently launched to the market.

The data concerning the performance and safety of the devices are gathered in various time frames starting with pre-operative status and then includes operative, at discharge, i year post-operative and 2 year post-operative evaluations.

The revision rate of the components will be monitored as the primary objective, along with pre- and post-operative measurement of the Oxford Hip Score(OHS) patient-reported outcome measure(PROM) to quantify patient satisfaction and radiographic analysis to monitor the bony response to the implants and quantify the effectiveness of the cementless fixation.
