Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is a pre and post-operative rehabilitation program consisting of Physiotherapy exercises through a mobile electronic application.
The program will be delivered on an individual level via a telemedicine platform.
The program will be monitored and modified by one experienced orthopaedic Physiotherapist.
Participants in the interventional group will be able to contact the Physiotherapist via telephone or email at any point during the program, 6 weeks pre-operative and 6-weeks post-operative, to discuss their progress.
A participants individualised program will be implemented 6 weeks pre-operative following an initial assessment of the patient. The program will be progressed at a minimum of fortnightly.
The participants intervention will be personalised as each participant may have different areas of strengths and weaknesses and thus a personalised approach will lead to a better outcome.
This initial personalisation will occur following the initial assessment 6 weeks pre-operatively and will be based upon clinical judgement and reasoning, An individuals program may be altered at any time due to feedback from the participant, further assessment of the participant or general progression of the individuals program.
The strategies used to monitor adherence will be through the mobile electronic application where participants will be required to log exercises completed, any pain association with exercises and any further comments regarding the exercise. Participants will complete this log daily.

Comparator / control treatment
The control group will be provided current standard care prior to and after their surgery.
Standard care for the control group will be no pre-operative Physiotherapy care.
Post-operative standard care will include acute inpatient Physiotherapy prescribed by the ward Physiotherapy team. The participant will also be provided with a discharge program from the hospital Physiotherapy staff.

Statistical methods / analysis
The number of patients required has been calculated based on power analysis. The sample size has been chosen from length of stay where a minimally important cost effective difference is 3 days, with a standard deviation of 5.8, which has been established from a pilot study we previously completed. Using a significance level (alpha) of 0.05 and a beta of 0.2, 120 total samples will be required to find the minimally significant economic difference.
