Background: Adhesive capsulitis is adisease characterized by the spontaneous onset of shoulder pain and global limitation of both active and passive shoulder motion. The main aim of this study was to evaluate and compare early results of MUA and ACR in management of primary frozen shoulder after failure of conservative treatment. Methods: This prospective study was carried out on Thirty patients with primary frozen shoulder, half of them were treated with MUA (group 1) and the other half treated with ACR (group 2) and followed for a minimum of 6 months. The study conducted at Orthopedic Surgery department, Faculty of Medicine, Benha University. Results: In the present study, no significant difference was found between MUA and ACR.  We found negative moderate correlation between age and Constant Murley score. We found also that there was statistically significant negative strong correlation between HbA1C and Flexion and External rotation, and a statistically significant positive strong correlation was found between HbA1C, OSS and internal rotation. Both MUA and ACR treatments give high satisfaction rate but cases treated with ACR were more satisfied but with no significant difference with MUA treatment. Conclusion: Successful clinical and functional outcomes can be obtained with both MUA and ACR in the treatment of refractory FS without major serious complications.
