Plain English summary of protocol

Background and study aims
Arthroscopic shoulder stabilisation is a commonly performed operation to treat recurrent dislocation of the shoulder. There is lack of agreement about rehabilitation after arthroscopic shoulder stabilisation surgery, with most surgeons recommending immobilisation of the shoulder for three to six weeks after surgery to allow the ligaments to heal and prevent recurrence. However, one of the risks of prolonged immobilisation is residual shoulder stiffness. Advocates of early mobilisation argue that there is no apparent increased risk of recurrence and excess stiffness is avoided. It also permits early strengthening and exercises. The aim of this study is to assess the recurrence rate and shoulder function of patients after arthroscopic stabilisation of the shoulder with two different rehabilitation regimes.

Who can participate?
Patients with recurrent shoulder instability undergoing arthroscopic anterior shoulder stabilisation

What does the study involve?
On the day of surgery, participants are randomly allocated to either the early mobilisation (EM) or sling immobilisation (SI) group. The EM group is immediately allowed to move the shoulder freely as pain allows. The SI Group is kept in a sling for 6 weeks. All participants are followed up at 6 weeks, 3, 6, 12 and 24 months to assess their shoulder function and to find out whether the surgery has worked or not.

What are the possible benefits and risks of participating?
The results will show which rehabilitation programme is best for patients undergoing arthroscopic shoulder stabilisation surgery. Possible benefits of early mobilisation include reduced risk of stiffness and increased proprioception (the body's ability to sense joint movement and position). The risk of early mobilisation is the theoretical risk of the surgical repair failing.

Health condition(s) or problem(s) studiedArthroscopic anterior shoulder stabilisation for instability
InterventionOn the day of surgery, participants were randomised using sealed envelopes to either early mobilisation (EM) or sling immobilisation (SI) group. The EM group was allowed to move the shoulder freely as pain allowed immediately. The SI Group was kept in a sling for 6 weeks. All patients were followed up at 6 weeks, 3, 6, 12 and 24 months. Their function and failure of surgery were assessed using Oxford Shoulder Instability Score (OSIS).
