Comparing immediate and delayed weight-bearing after ankle surgery

Immediate vs Delayed Weight-bearing After Surgical Treatment of Malleolar Fractures: a Randomized Controlled Trial

Not applicable Interventional Ente Ospedaliero Cantonale, Bellinzona · NCT04429217

This study tests whether allowing patients to put weight on their ankle right after surgery helps them recover better than waiting six weeks to do so.

What this trial studies

This study evaluates two rehabilitation protocols for patients undergoing surgery for lateral malleolus fractures: immediate complete weight-bearing versus delayed weight-bearing for six weeks. The aim is to determine if immediate weight-bearing can enhance functional recovery without increasing complications. The study will involve 100 patients who meet specific eligibility criteria, including adults aged 18 to 70 with stable Weber A or B fractures. Participants will be randomly assigned to one of the two rehabilitation groups following their surgical procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 70 with stable Weber A or B lateral malleolus fractures requiring surgical intervention.

Not a fit: Patients with Weber C fractures, bilateral fractures, or significant medical comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to faster recovery times and improved functional outcomes for patients after ankle surgery.

How similar studies have performed: Previous studies have shown promising results with immediate weight-bearing protocols in similar fracture types, suggesting potential for success in this approach.
