Brief summary
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.
Detailed description
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.
Interventions
DEVICEGame-based rehabilitation exercise
4 games (exercises) on operated limb, for 3 sessions daily, until outpatient physiotherapy review visit.
OTHERConventional brochures of rehabilitation exercise
4 exercises on operated limb, 30 reps each, for 3 sessions daily, until outpatient physiotherapy review visit.

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