What this trial studies

This observational study aims to evaluate the accuracy of a limp detection model following total knee arthroplasty using the Canary canturioTM te tibial extension. Patients will be assessed for limp severity by healthcare providers at a 4-6 week follow-up visit, utilizing a 3-point Likert scale to categorize the severity of their limp. The study will include patients who are indicated for a commercially available PersonaIQ TKA implant and are willing to participate in the follow-up protocol. The goal is to improve the assessment of post-surgical recovery and walking ability.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for a total knee arthroplasty with a PersonaIQ implant.

Not a fit: Patients undergoing simultaneous bilateral total knee arthroplasties or those with significant psychiatric or cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of limp assessments, leading to better post-operative care and recovery strategies for knee surgery patients.

How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, indicating that this may be a novel assessment method.
