Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals scheduled for total knee arthroplasty who meet the inclusion criteria.
✕Probably not a fit
Patients who are not undergoing knee arthroplasty or do not meet the eligibility criteria may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study aims to evaluate patient satisfaction following total knee arthroplasty using two different implant systems: the patient-matched ORIGIN® and the off-the-shelf VANGUARD® PS. It involves a prospective, comparative design with 140 subjects and includes a two-year follow-up to assess clinical and device performance outcomes. The study is conducted in a single center, focusing on real-world hospital practices and patient experiences.
Why it matters
Potential benefit: If successful, this study could lead to improved patient satisfaction and outcomes in knee replacement surgeries.
How similar studies have gone: Other studies have shown success in comparing different knee implant systems, indicating that this approach is supported by prior research.
