Description of intervention(s) / exposure
Participants randomised to the MAXM Skate group will be required to undertake the MAXM Skate rehabilitation program. This involves using the skate device and accompanying Smart device App and sensor to complete a 12-week Rehabilitation Exercise Program. These exercises are pre-set and progressed across a 4-phase Program.

A patient must download the MAXM Skate App from their app store. They will log in using their Mobile phone as an identifier to access their user account.

The Exercise program requires the patient to complete 3 variations of Skate exercise: Flat Skate, Extension Skate and Flexion skate. These exercises are completed in a chair, utilising the device to move through Knee Joint flexion and Extension. The Skate exercises are also complemented with other TKA strength and movement Rehab exercises such as inner range quads, squats, lunges and walking to make it a full end-to-end program. The exercise challenge increases as a participant progresses through the post-operative weeks.

The participant will then be required to wear a sensor module on the operative leg when completing an exercise session. Each session is approximately 25 minutes, with two sessions to be completed per day. Accelerometer data representing the angle of the device relative to gravity is sent to the phone and through an algorithm, displayed to the participant as a % of their full knee ROM (135 deg).

As patients complete exercises within their app. It collected the reps and set data along with ROM data to monitor exercise adherence and compliance. Pain scores are also entered by the patient at the end of each exercise completed.

No Exercise intensity measure are taken.

Power Calculation:

A sample size calculation based on achieving 90% power and a Type 1 error rate of 5% was chosen. The calculation determined that 110 participants (55 participants per group) would be required to detect a 10° difference in ROM between the MAXM program and SC groups three months after TKA assuming a within-group standard deviation (SD) of 16°. The clinically significant difference in ROM of 10° was estimated based on parameters described by Mockford colleagues (Mockford et al., 2008) in which the effect of a physiotherapy regimen on ROM was measured over a one-year post-TKA follow-up period. To account for a potential 10% loss to follow-up, a total sample of 124 participants (62 per group) is to be recruited.

Summary
Brief summary
The aim of this randomised controlled trial is to compare the safety and efficacy of the MAXM Skate Rehabilitation Device and associated digital rehab program to standard rehabilitative care for elective Knee Arthroplasty Patients in a Public Health Setting.

Comparisons will be made between several functional, self-reported and performance-based outcomes measures until the completion of their rehab program 3 months post total knee arthroplasty.

It is hypothesised that a TKA patient, in a public health care setting, uses MAXM Skate Device and digital rehab program then they will experience equal or greater return of function, clinical performance, and satisfaction in comparison to those receiving standard rehabilitative care.
