To find the best type of joint replacement for the treatment of painful osteoarthritis of the shoulder in adults aged 60 years or older.
With increasing age, shoulder osteoarthritis is common and causes severe pain and stiffness making everyday activities difficult. A shoulder replacement is an effective solution, reducing pain and allowing the shoulder to function better.
There are two types of shoulder replacement:
The rotator cuff can weaken with age which may cause an anatomic replacement to stop working. This could mean a further operation to change the shoulder to a reverse total shoulder replacement. For this reason, an increasing number of patients are offered reverse shoulder replacements even when their rotator cuff is intact. Currently, there is no scientific evidence to support this change and no guidance to recommend which is the best type of shoulder joint replacement. This trial aims to provide clinical evidence for the superiority (or not) of reverse shoulder replacements over anatomic. We also aim to inform which is the most cost-effective option to the NHS, explore patients’ expectations of the two types of shoulder replacement, and to link with the National Joint Registry for data on patient mortality and revision rates.
The research will be undertaken in NHS shoulder arthroplasty units in England, Wales and Northern Ireland. Patients will be screened for eligibility (suitable for shoulder arthroplasty and intact rotator cuff) and invited for recruitment prior to surgery. Patients will be randomised prior to surgery and will be blinded to which type of replacement they received. We will recruit 430 patients and follow their recovery and outcomes periodically over the course of 24 months. We will also conduct a nested qualitative study of 20 participants who will be interviewed at 2 and 12 months after surgery.
The study Sponsor is Wrightington, Wigan & Leigh NHS Foundation Trust with funding from the National Institute for Health Research Health Technology Assessment Programme. Professors Ian Trail at Wrightington and Joe Dias at University Hospitals of Leicester NHS Trust are the joint Chief Investigators. The RAPSODI-UK trial group is collaborating with a linked application through the NIHR-NHMRC collaboration to run a parallel trial to the same protocol in Australia. Professors Richard Page at Deakin University, Australia and Nadine Foster at the University of Queensland, Australia are co-applicants of the RAPSODI-UK trial.
