Arthroscopic capsular release is the main surgical treatment method for the patients with frozen shoulder who can not be treated with conservative methods. Detection and simultaneous treatment of concomitant shoulder pathologies, 360° controlled release of the capsule and letting early rehabilitation are the advantages of arthroscopic release. The most important structure to be considered during capsular release is the axillary nerve. The capsule should be released from the part close to the glenoid and the close relation of the axillary nerve to the capsule should not be forgotten between 5 and 7 o`clock positions. Interscalene catheter placement is important for postoperative pain control and early rapid rehabilitation. Arthroscopic capsular release with early rehabilitation is a successful method with a low complication rate that can achieve similar functional results with the contralateral shoulder.
