Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the intervention group, patients will receive the standard physiotherapy intervention by attending physiotherapist and be taught how to play the game on post op day 1. The exercises taught via the game (straight leg raise and heel slides), will not be taught in the traditional manner. Apart from the 2 exercises, all standard physiotherapy interventions will be carried out.

From day 2 onwards, patients will play the supergramps game for knee ranging and muscle strengthening exercises without standard physiotherapy intervention. These patients will continue to be seen once daily by the physiotherapist to be assessed and ambulated with an appropriate walking aid during their inpatient stay. They would be advised to play the game 3x a day.

Patients in the intervention group will be provided with an inertial measurement unit (IMU) which is a triangular device which they are to put on. The device will be taped onto silicon belts, which the participants are required to place around their thigh and calf. The device will be able to communicate with the game on a tablet provided in order to facilitate participation of the patient. The game will require the patient to control the character either by bending their knees or lifting their legs, similar to the exercises done post-total knee arthroplasty surgeries.
Patients will be encouraged to do these exercises 3x/day, as per usual protocol. The game should take about 10-15 minutes to complete.

The participants are required to play the game for 3 days post surgery, after which the inertial measurement units and tablets will be collected back. We will monitor adherence to the game by checking their game results on a separate portal.

Rehabilitation
Comparator / control treatment
In the control group, patients will receive the standard physiotherapy
intervention daily as per knee arthroplasty protocol for knee ranging and muscle strengthening exercises during their acute inpatient hospital stay. Exercises taught include heel slides, static quadriceps contraction, inner range quadriceps activation, straight leg raises. They will be seen once a day by the physiotherapist and encouraged to do the exercises twice in their own time.

The usual orthopaedic team members will be carrying out the control treatment.
