Description of intervention(s) / exposure
The RECOVERY APP will guide participants:
• With an animated surgeon which provides two separate voiced-animations (VA) that are
designed to introduce participants to the both the prehabilitation and the rehabilitation programs. A component of the study is to evaluate if participants can successfully download the Recovery App, "onboard" and learn to use the App without the assistance of a health professional as this App is intended for use in both urban and rural settings. In this pilot study, participants will download the App at 4 weeks preoperatively. At the 3 week preoperative clinic visit at RNSH, one of the project team physiotherapists will assess the participants on how successfully they have learnt to use the App and also how well they are doing their exercises.
• On a graded prehabilitation exercise program which will commence 4 weeks before total knee arthroplasty (TKA) surgery. The exercises used are the exercises that they will be expected to perform on the day of surgery, as soon as possible after they return to the ward. Participants will be expected to learn how to do the exercises from the VAs on the Recovery App and will not be given any assistance with this unless a request is made to the nominated orthopaedic registrar.
At his/ her discretion, contact can be made with nominated physiotherapists at RNSH for further explanation or assistance. In addition participants will be supplied with crutches and instructed on their use with the assistance of a VA at their preoperative visit 3 weeks before surgery if they are deemed suitable at the time of assessment.
Participants will be notified on the exercise screen how many repetitions are recommended by the physiotherapist and the participant will click on a numbers table which is a pop-up on the screen to indicate how many repetitions they achieved. Total time on prehabilitation exercises is expected to be 15-30 minutes twice per day for 4 weeks, in addition to tracking steps taken with a goal of graded increases in daily steps pre-operatively.
• on the use of active pain management strategies (pacing, mental imagery, problem solving,
managing pain flare-ups and applied relaxation) through a series of VA embedded in the APP.
• functional data and scores on self report questionnaires will be displayed in tables or graphically
• on a rehabilitation program which commences on the day of surgery and continues for 6 weeks. Rehabilitation exercises are expected to take 15-45 minutes, 3-4 times per day in addition to graded increase in daily steps taken (with reduction in gait aids as patient's balance and strength improves).
After 6 weeks participants will not be guided on exercises but will be asked to complete the same questions. Any need for further exercise progressions will be according to usual care by
physiotherapy and their surgeon. There will be a further completion at 12 weeks of the same
battery of validated psychosocial questionnaires that were completed 4 times previously during the pilot study. The exercises used in this program are voiced animations of the exercises in the AdvaNSYD Pathway of the North Shore Local Health District New South Wales Australia (NSLHD) and the animations are also approved by our project team physiotherapists.

Use of the APP will be monitored based on participant recording (or not) of number exercises completed, completion of questionnaires, APP analytics, steps taken recorded via accelerometer in phone (predicated on participants carrying phone)

Exercises included:
Prehabilitation phase- Static Quads, Heel slides, Bridges, Inner range Quadriceps, Sit to stand, Seated press-ups , Wall push ups, 1/4 squat at bar, Heel raises, Step up, Walking, Practice using crutches
Rehabilitation phase- Ankle circles, Static Quads, Heel slides, Inner range Quadriceps, Sit to stand, Seated knee flexion, Heel raises, Walking (initially with assistive devices), Knee flexion/ lunges on step, Hamstring stretch, Heel raises, Calf stretch, Balance exercises: step stance, 1/4 squat at a bar. Stair climbing and descending, Prone knee flexion: hamstring curl, Prone quadriceps stretch, Prone knee extension

The exercises included are a relatively low level of intensity when performed at low repetitions, the intensity is increased by increasing number of repetitions or number of sets of exercises.

The AdvanSYD pathway is an initiative by the NSLHD which aims to deliver excellent care for patients requiring lower limb arthroplasty by providing appropriate, efficient, equitable care which aligns with evidence based practice. This is a district wide initiative with patients related goals of patients receiving appropriate, efficient and equitable care measured through:
- Patient outcome measures are collected and evaluated; outcome measures are achieving state benchmarks.
- Reduced variation in care processes.
- Improved cost-effectiveness compared to state benchmarks.
- Informed recommendation of appropriate strategy for prostheses management; prostheses use is cost effective and clinical outcomes are maintained.

The processes used to achieve this are:
1. Providing a ‘Patient Roadmap’ that outlines appointment/steps a patient will take, and key messages e.g. that most patients return directly home
2. Patients attending a ‘Joint Class Education Session’ that reinforces these messages and allows an opportunity to answer questions.
3. A GP Letter is sent to GPs with the waitlist letter and given to patients at Joint Class
4. Anaesthesia and Analgesia Guidelines are distributed and followed as appropriate
5. A Protocol for the ‘Quickstep Group’ (Low risk patients) is followed, including:
a. Surgeons liaise with Anaesthetists regarding intraoperative recommendations
b. Surgeons direct patients to the Quickstep Protocol as appropriate, and orthopaedic ward staff follow the protocol as per role
c. A ‘Patient Recovery Guide’ (a daily checklist) is given to patients to follow
6. A Discharge Path and Criteria including:
a. Patients are discharged using the ‘criteria led discharge’ and discharge path, with reference to the Acute Post Acute Care Outline
b. Patient follow-up and escalation is arranged as per protocol.

Within the pathway, consensus recommendations for typical anesthetic/analgesic treatments and typical mobilization/ exercises have been developed.

Statistical methods / analysis
As this is a pilot study and therefore no statistical hypothesis testing will be conducted,
sample size is based on practical considerations. We estimated that a full randomised
controlled trial would require 300 patients, so for this pilot study we have selected 10% of
this number, so 30 patients be will studied. As no account will be taken of preoperative
functional status or social support available postoperatively, some participants may not be
discharged home and will go to inpatient rehabilitation. Inpatient rehabilitation takes place
at a number of sites so it is unrealistic to obtain site specific approval for this pilot study to
be performed at all these potential centres so these participants will be recorded as
"ineligible postoperatively". This may mean that more than 30 participants are enrolled to
achieve our pilot number of 30 participants. The in-patient rehabilitation rate is less than
20% in public hospitals so total enrolled participants should not exceed 40.

Descriptive statistical analysis will be used, as there is no comparator group we do not have pre-described comparative statistics planned.

Summary
Brief summary
Hypothesis: The use of prehabilitation and rehabilitation coordination and support using the Internet of things (via a smart phone App) will allow personalisation of therapy and improve recovery from knee replacement in these patients.

This study will provide important information in these areas
1. Can the delivery of significant components of care be by the Internet
of things (IoT). The PRIMO protocol would standardise components of care at
RNSH. In NSLHD, up to 60% of patients are “out of area” This study will not include
these patients but it is envisaged that the RECOVERY APP will be associated
with improved outcomes in this group and they will be studied as part of a separate
HREC application at an appropriate time.
2. Does the RECOVERY Platform result in improved adherence to rehabilitation prescriptions and improved outcomes in a range of domains that inform a new standard of care.

This study is not sufficiently powered to show statistically significant changes nor does it have a comparative arm.
