Summary

Anatomical total shoulder arthroplasty (TSA) is a well-established treatment for pronounced glenohumeral osteoarthritis. However, the effectiveness of TSA has not been compared to non-surgical treatment in a randomised controlled trial. Shoulder exercises may be an effective treatment for reducing pain and improving function in glenohumeral osteoarthritis. The primary aim of this trial is to examine if TSA followed by standard postsurgical rehabilitation is superior to a 12-week exercise programme in patients with primary glenohumeral OA eligible for unilateral TSA. We hypothesise that surgical intervention followed by standard rehabilitation, results in clinically relevant (18-point, on a scale from 0-100) improvement compared to the exercise intervention.

Detailed description

Glenohumeral osteoarthritis causes pain, stiffness and weakness in the shoulder joint, and furthermore, it affects activities of daily living and quality of life. Anatomical total shoulder arthroplasty (TSA) is a well-established treatment for pronounced glenohumeral osteoarthritis. Several studies have suggested the need for trials comparing shoulder arthroplasty to non-surgical treatments. The ProAct trial is a Nordic multicenter randomized controlled trial. Patients with glenohumeral osteoarthritis, eligible for a TSA will be randomised to either TSA followed by usual care or exercise only. The exercise intervention consists of 12 weeks of exercise with one weekly physiotherapist-supervised exercise session. The primary outcome will be the total the Western Ontario Osteoarthritis of the Shoulder index score at 12 months follow-up.Outcome assessment will be performed at baseline, and at 3 and 12 months and 2-, 5- and 10 years after start of surgical/non-surgical treatment. Patients fulfilling the eligibility criteria but declining to participate in the randomised trial will be offered the option of participating in an observational cohort using the same primary end point and patient reported outcomes, but following usual clinical practice.

Conditions

• Glenohumeral Osteoarthritis

Interventions

Type	Name	Description
PROCEDURE	TSA-group	Anatomical total shoulder arthroplasty followed by standard rehabilitation.
OTHER	Exercise-group	The exercise-group will attend a 12-week exercise program with one weekly physiotherapist-supervised session supplemented with two weekly sessions of home-based exercises. Utilisation of a predefined training protocol describing procedures and content of each session secure uniformity and standardisation of the intervention. The exercise program consists of two warm-up exercises and five exercises that target shoulder range of motion and muscle strength. Furthermore, a link to a video, informing about glenohumeral osteoarthritis, the role of exercise and exercise related pain, will be sent to all patients in the exercise-group. The physiotherapists delivering the exercise intervention are not otherwise related to the trial.
