Purpose: The aim of this study was to compare shoulder manipulation and arthroscopic arthrolysis with glenohumeral steroid injections in patients affected by idiopathic adhesive shoulder capsulitis.
Methods: In this prospective study we randomly assigned patients to enter group A (23 patients, shoulder manipulation and arthroscopic arthrolysis) and group B (21 patients, glenohumeral steroid injections). Patients were followed-up at three, six and 12 weeks, and at six and 12 months with the Constant and Murley, ASES, UCLA and SST evaluation scales.
