This study aims to investigate the effect of Smart Kneebrace use for osteoarthritis patients after total knee arhtroplasty (TKA) on post-operative performance.
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.

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.
regular rehabilitation procedure, especially muscle strengthening exercises
The change of postoperative joint angles
Patients in both groups will wear the smart kneebrace by which the range of motion of the knee joint can be calculated.
Time frame: before operation and 6/12 weeks after operation
The change of knee pain.
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.
Time frame: before operation and 6/12 weeks after operation
The change of knee symptoms.
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.
Time frame: before operation and 6/12 weeks after operation
