This study aims to evaluate the effectiveness of a novel, game-based rehabilitation system, consisting a sensor-equipped knee sleeve and a mobile application, on rehabilitation outcomes after Total Knee Arthroplasty (TKA) surgery, when compared to conventional rehabilitation; where patients learn and perform rehabilitative exercises using printed brochures.
This is a randomized controlled trial investigating the effectiveness of a novel, game-based rehabilitation system, consisting a sensor-equipped knee sleeve and a mobile application, on rehabilitation outcomes after Total Knee Arthroplasty (TKA). All patients receiving TKA will be screened for eligibility. Patients who meet inclusion criteria and provide informed consent will be allocated to either intervention or control group using block randomization. A study team member blinded to subject characteristics will allocate subjects to either group. Subjects in the intervention group will be guided to do their post-TKA rehabilitation exercises using the investigator's game-based system, which includes the wearable sensor device and mobile application games. Subjects in the control group will be guided to do their post-TKA rehabilitation exercises using conventional, paper-based exercise brochures. From post-operative day 1, all subjects who are medically fit for physiotherapy will receive 2 sessions of physiotherapy, daily; for at least the first 3 post-operative days. The first session consists of individualized physiotherapy that includes bed exercises and ambulation training. In the second session of physiotherapy, subjects will perform their bed exercises using the game-based system or paper-based exercise brochures. Upon discharge, subjects in the intervention group will continue home-based rehabilitation exercises using the game-based system, while those in the control group continue to use the exercise brochures.

RECRUITINGPain Intensity
Visual analogue scale (0-10) for participant-reported pain intensity. Maximum score (10) for worst pain, minimum score (0) for no pain.
Time frame: Difference in pain score between hospital discharge and first outpatient physiotherapy review (within 3 weeks post-operation)
Knee flexion range of motion
Passive range of knee bending motion measured by handheld goniometry (ranging from -15 to 150 degrees), measuring angle formed by between femur and fibula.
Time frame: Difference in angle between hospital discharge and first outpatient physiotherapy review (within 3 weeks post-operation)
Knee extension range of motion
Passive range of knee straightening measured by handheld goniometry (ranging from -30 to 20 degrees), measuring angle formed by between femur and fibula.
Time frame: Difference in angle between hospital discharge and first outpatient physiotherapy review (within 3 weeks post-operation)
Ambulation status
Use of gait aid, assistance during walking in the home or community
Time frame: At hospital discharge, at outpatient review (2-3 weeks post-operation), at outpatient discharge or 3 months post-operation
