Description of intervention(s) / exposure
In shoulder replacement surgery, Orthopaedic Surgeons remove the damaged parts of the shoulder joint (natural bone) and replace them with plastic or metal parts. For Reverse Total Shoulder Replacement (rTSR) procedures, the arrangement of the ball and socket components are reversed, the metal ball is attached to the inside of the shoulder blade (instead of the humeral stem), making use of the deltoid muscle for movement of the arm. It does not rely on an intact or functioning rotator cuff. This type of surgery is used routinely in Australia and is anticipated to take two to three hours. The surgery will be conducted by skilled Upper-Limb Orthopaedic surgeons and they will be Investigators in the RAPSODI-AUS trial. Patients will be screened by the surgeon and site coordinator to ensure eligibility for the trial, specifically for 60 years of age and over with painful osteoarthritis (OA) of the shoulder joint with an intact rotator cuff and bone stock suitable for shoulder arthroplasty. Eligible patients will be provided with a Patient Information Sheet, surgeon will discuss the trial and obtain informed consent. They will be registered in the online Australian Orthopaedics Association National Joint Replacement Registry (AOANJRR) portal.
Details of the implants and techniques used will be recorded in the routinely collected AOANJRR data form, obtained during the procedure. There will also be a number of other Surgeon/Site case report forms (CRFs) and these processes will be monitored for completeness and compliance by the AOANJRR Clinical Studies team for the duration of the study.
Patients will also provide responses to questionnaires via an online portal - these will be collected preoperatively, and at 3, 6, 12, 18 and 24 months. They will be invited to complete the surveys via sms text or email, with telephone calls as a back up to assist patients who may need help. There will be an embedded Qualitative substudy of approximately 20 selected patients, participating in semi-structured interviews at 2 months and 12 months. (40 interviews in total). These participants will have indicated willingness to participate at initial consent. Using purposive sampling of 10 from each arm of the study - aTSR and rTSR - and variation in age and geographical location, from a minimum of 4 study sites. This will be to gain a range of perspectives and a rich understanding of participants' experiences and perceptions. Additional participants may be recruited at 12 months, using trial pain/function data to inform selection.

Comparator / control treatment
Anatomical total shoulder replacement (aTSR) is a conventional shoulder replacement which mimics the natural ball and socket structure of the joint and relies on the presence of an intact rotator cuff for useful range of movement. The metal ball is attached to the humerus, and the replacement relies on these small muscles around the shoulder joint working well. If these muscles (rotator cuff) weaken over time, further surgery may be required. The choice of implant will depend on local practice at recruiting sites but will include any anatomical shoulder implant from any manufacturer licensed for use in the Australia implanted using techniques consistent with manufacturer instructions. This type of surgery is used routinely in Australia and is anticipated to take about three hours. The surgery will be conducted by skilled Upper-Limb Orthopaedic surgeons and they will be Investigators in the RAPSODI-AUS trial. Patients will be screened by the surgeon and site coordinator to ensure eligibility for the trial, specifically for 60 years of age and over with painful osteoarthritis (OA) of the shoulder joint with an intact rotator cuff and bone stock suitable for shoulder arthroplasty. Eligible patients will be provided with a Patient Information Sheet, surgeon will discuss the trial and obtain informed consent. They will be registered in the online Australian Orthopaedics Association National Joint Replacement Registry (AOANJRR) portal.
Details of the implants and techniques used will be recorded in the routinely collected AOANJRR data form, obtained during the procedure. There will also be a number of other Surgeon/Site case report forms (CRFs) and these processes will be monitored for completeness and compliance by the AOANJRR Clinical Studies team for the duration of the study. They will receive routine post-operative care, follow up and physiotherapy, as for any other shoulder replacement surgery patient not participating in the study.

Patient-reported shoulder pain and function as assessed by the combined Shoulder Pain and Disability Index (SPADI) score.
The 13-item SPADI is a validated and sensitive instrument for use in shoulder arthroplasty that assesses two domains; pain (5 items) and functional activities (8 items) on numerical rating scales, to provide a combined score.

Responses will be on a 5-point Likert scale with the following options: much improved, improved, same, worse, and much worse. This will only be asked at the end of the study (24 months post-procedure)

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will involve contacting the AOANJRR (holder of the allocation schedule). The allocation schedule will be generated by a senior registry statistician, otherwise not involved in the recruitment or randomisation of participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation will be 1:1, using random permuted blocks of random block size, stratified by age (60-69; 70+) as a surrogate of deteriorating shoulder rotator cuff function.

The primary comparison of interest is the between-groups difference in SPADI score at 24 months. To make use of all available observations from all time-points in the trial, the estimate for the difference at 24 months will be derived from a constrained longitudinal data analysis (cLDA) model. The model will be a linear mixed-effects model, featuring SPADI score as the outcome, intervention group, time-point (coded as dummy variables to denote the baseline, 3, 6, 12, 18, or 24-month time-points), age and gender as fixed effects, and participant identifier and study site as random effects. A series of group-by-time point interaction effects will be included as fixed effects, thereby making no assumptions about the shape of the SPADI score trajectory over time. The model will be constrained so that the baseline SPADI scores are equal between groups. The model will use maximum likelihood estimation, with an unstructured covariance matrix. The between-groups difference in SPADI score at 24 months will be extracted from this model as the primary outcome and reported with a 95% CI and p-value.

The between-group differences for combined SPADI score at 3, 6, 12 and 18 months, and over 24 months will also be extracted from the primary analysis model as secondary outcomes. The other secondary continuous outcomes (e.g. SPADI pain and function subscale scores, OSS) will be analysed using an identical mixed-effects model to the primary outcome analysis, with the same covariates and covariance structure. The outcome in these models will be replaced with each of the secondary outcomes of interest. The OSS model will not feature an 18-month time point, as this outcome is not collected at this time. While also a continuous secondary outcome, the EQ-5D-5L will exclusively be used in the economic evaluation.
Range of movement and strength are collected at two time-points (baseline and 24 months). The 24-month outcomes for these measures will be compared via a mixed-effects linear regression model with intervention group as the predictor variable, as well as age, gender and baseline value of the outcome, and site as a random effect.
The ordinal outcome of global shoulder score at 24 months will be analysed using mixed-effects ordinal logistic regression, adjusting for age, gender, and baseline combined SPADI score, with site as a random effect.
Time-to-event outcomes (time to revision/re-operation/death) will be explored by comparing restricted mean survival times between intervention groups (as we suspect that proportional hazards-type analyses may be inappropriate for these outcomes).
Safety outcomes (adverse event rate, complication rate and types of complication) will be summarised across all time-points at which they are collected.
