Monitoring recovery after knee replacement using wearable sensors
Investigating the Potential of Wearable Sensors for Monitoring the Postoperative Recovery of Total Knee Arthroplasty Patients: A Protocol for Prospective Longitudinal Observational Study
This study is testing if wearable sensors can help track how well people recover after knee replacement surgery by monitoring their activity and walking patterns.

What this trial studies
This observational study aims to explore the effectiveness of wearable sensors in tracking the postoperative recovery of patients following total knee arthroplasty (TKA). Participants will wear physical activity trackers from two weeks before surgery until three months post-surgery, and again for two weeks one year later. The study will analyze gait characteristics and physical activity levels to determine their correlation with recovery outcomes. By providing continuous monitoring, the study seeks to enhance patient management and identify potential complications early.
Who should consider this trial
Good fit: Ideal candidates are patients diagnosed with knee osteoarthritis scheduled for unilateral total knee arthroplasty.
Not a fit: Patients with severe pain in other joints, neurological disorders, or those who are not smartphone users may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to improved recovery monitoring and outcomes for patients undergoing knee replacement surgery.
How similar studies have performed: Previous studies have shown promise in using wearable technology for monitoring recovery in various surgical contexts, indicating potential success for this approach.
