Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 40 to 75 with unilateral ankle osteoarthritis who are suitable for primary total ankle replacement.

Probably not a fit

Patients with severe comorbidities, neurological disorders, or those requiring additional surgical procedures 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 study aims to compare the outcomes of customized total ankle replacements (TAR) tailored to individual patients' ankle morphology with standard TAR procedures. It will evaluate objective radiological results, subjective patient outcomes, and the overall costs associated with both approaches. The customized prostheses are designed using tomographic scans and implanted with patient-specific cutting guides. The goal is to determine which method provides better results for patients suffering from ankle osteoarthritis.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and patient satisfaction for those undergoing ankle replacement surgery.

How similar studies have gone: Other studies have shown promising results with customized orthopedic implants, suggesting potential success for this approach.
