Description of intervention(s) / exposure
Patients undergoing Total Knee Replacement for Osteoarthritis will be asked to complete a pre-operative survey (ARISE rehabilitation screening tool). Patients will be observed from admission for their total knee replacement surgery until their discharge from the hospital.
The ARISE (Arthroplasty Rehabilitation Initial Screening Evaluation) tool will be used for the first time in this study, question responses will undergo statistical analysis to determine level of predictability for discharge destination. The ARISE tool consists of 13 questions across 4 health domains and should take approximately 5 minutes or less to complete. The ARISE tool will also be assessed with regards to it's correlation to the well-validated EQ5D tool which participants will be asked to complete at the same time.

Outcomes
Primary outcome [1] 321664 0
Discharge destination (Home vs rehabilitation in an inpatient hospital facility) will be recorded by the physiotherapist on day of discharge, there is also a record of discharge destination in the patient's hospital notes that may be used.

Secondary outcome [1] 375809 0
EQ5D-5L
The EQ5D 5L questionnare comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions.

ARISE questionnaire
The ARISE (Arthroplasty Rehabilitation Initial Screening Evaluation) questionnaire is comprised of 4 themed sections: living situation, physical function, psychosocial, and attitude towards exercise interventions. Within each section, there are 3-6 individual questions with responses to be answered on a Likert style scale. The ARISE questionnaire will be used for the first time in this study and will be assessed for it's correlation to the well-validated EQ5D tool, which is also a listed secondary outcome.

Statistical methods / analysis
The sample size of 100 participants will be based on existing literature which developed a prediction model for patient satisfaction following total knee replacement surgery (Van Onsem, S., Van Der Straeten, C., Arnout, N., Deprez, P., Van Damme, G., & Victor, J. (2016). A New Prediction Model for Patient Satisfaction After Total Knee Arthroplasty. J Arthroplasty, 31(12), 2660-2667.e2661. doi:10.1016/j.arth.2016.06.004)
Data analysis will be performed using IBM-SPSS Statistics 26 (SPSS,
an IBM Company, Chicago, IL). Level of statistical significance will be set to
0.05. The model will be built under the supervision of a biostatistician with the aim to evaluate the predictive effect of the ARISE score. Each ARISE question will undergo both univariable and multivariable analyses to report it's predictiveness of inpatient rehabilitation as a discharge destination. Demographics will be analyzed and compared between the
home and rehabilitation groups using an independent samples t test.

Summary
Brief summary
The primary aim of this study will be to determine if a pre-operative questionnaire, the ARISE tool, can predict discharge destination to home or inpatient rehabilitation following primary total knee replacement surgery. Existing tools have been criticised for not being predictive of "moderate" scorers, only predictive of those scoring in the high or low range categories. The ARISE tool is designed to capture additional information around a patient's beliefs rather than demographic features such as age and gender etc alone.

Results – plain English summary
After multivariable regression, the domain which contained three questions around beliefs about rehabilitation showed a 9.9 times greater likelihood of inpatient discharge. Not having someone to help at home also made inpatient discharge 6.3 times more likely. The final model demonstrated 84% correct predictivity. The ARISE trial demonstrated that patient beliefs about inpatient rehabilitation are highly predictive of discharge destination. Questions on physical function were not predictive.
