Not applicable Interventional Stanford University · NCT06080152

This study is testing whether using a new mobility device called the A-Linker helps people move better after knee surgery compared to using a standard walker.

What this trial studies

This pilot study investigates the impact of two mobility devices, the A-Linker and a standard walker, on patient maneuverability and mobility following total knee arthroplasty. Patients are randomized into two groups, with one group using the A-Linker and the other using a walker for three months prior to their surgery. The study will assess changes in mobility through questionnaires administered at various intervals: at the start, six weeks, twelve weeks, and eighteen weeks post-surgery. The goal is to determine if the A-Linker offers significant advantages over traditional walkers in improving mobility outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals scheduled to receive total knee arthroplasty.

Not a fit: Patients who are not undergoing total knee arthroplasty will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance mobility recovery for patients undergoing total knee arthroplasty.

How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, making this a novel investigation.
