Using a smart ring to help recovery after knee replacement surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.
