What this trial studies
This clinical trial investigates the impact of a wearable activity tracker, specifically a smart ring, on the recovery process following total knee replacement surgery for osteoarthritis. Participants will receive standard postoperative care, including physiotherapy, while being monitored remotely through the smart ring for activity and sleep patterns. The goal is to determine if this technology can reduce the incidence of poor patient-reported outcomes one year after surgery. The study aims to enhance recovery by providing personalized feedback and support based on the monitored data.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 to 70 undergoing primary total knee arthroplasty for osteoarthritis who can use a smartphone and smart ring.
Not a fit: Patients with significant joint deformities, severe neurological conditions, or those unable to comply with rehabilitation protocols may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to improved recovery outcomes and patient satisfaction after knee replacement surgery.
How similar studies have performed: While the use of wearable technology in rehabilitation is gaining traction, this specific approach combining smart rings with physiotherapy is relatively novel and has not been extensively tested.
