Prosthesis Versus Active Exercise Program in Patients With Glenohumeral Osteoarthritis

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.

Conditions

• Glenohumeral Osteoarthritis

Interventions

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.
