Brief summary
This study aims to investigate the effect of Smart Kneebrace use for osteoarthritis patients after total knee arhtroplasty (TKA) on post-operative performance.
Detailed description
This is a single-center, open-label randomized controlled clinical trail. A total of 60 participants will receive total knee arthroplasty, who will be randomly assigned into experiment or control group. Smart Kneebrace will be used for the patients during the rehabilitation for the patients in experiment group, while the patients in the control group will not receive such a smart kneebrace. Postoperative joint angles as well as visual analog scale pain score, the Western Ontario and McMaster Universities Osteoarthritis Index knee society score will be estimated before operation and at 6/12 weeks after operation.
Interventions
DEVICESmart Kneebrace with a smart phone app
Smart Kneebrace will be used during the rehabilitation. Patients wearing the Smart KneeBrace are able to know their daily activity summary and exercise performance during rehabilitation training through a smart phone app.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The change of postoperative joint angles | before operation and 6/12 weeks after operation | Patients in both groups will wear the smart kneebrace by which the range of motion of the knee joint can be calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The change of knee symptoms. | before operation and 6/12 weeks after operation | The Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC),and its score ranges from 0 to 96. The higher the score is, the more severe symptoms the patient is feeling. |
| The change of knee pain. | before operation and 6/12 weeks after operation | Visual Analogue Scale of pain is a scale to extimate pain, and its score ranges from 0 to 10. The higher the score is, the more severe pain the patient is feeling. |
