Popis: Objective The thickened coracohumeral ligament (CHL) is an important part of the typical manifestations and magnetic resonance imaging of frozen shoulder. However, only a few clinical studies with limited cases on arthroscopic extra‐articular entire CHL release exist in the literature. This study was to evaluate the effect of arthroscopic extra‐articular entire CHL release for patients with recalcitrant frozen shoulder. Methods From February 2014 to February 2020, 81 cases of recalcitrant frozen shoulder patients treated with surgery in a single‐center shoulder department and followed for more than 2 years were analyzed. Arthroscopic 360° capsular release was performed with intra‐articular partial release (IPR group) or additional extra‐articular entire release (IPR + EER group) of CHL. The same rehabilitation program was performed after surgery in both groups. Visual analogue scale (VAS) for pain, range of motion (ROM), and the Constant–Murley scoring system was evaluated before operation, at 3 months after operation, 6 months after operation, and the final follow‐up. T‐test, Mann–Whitney U‐test and chi‐squared test were used to compared data. Results There were 39 patients in the IPR group, with an average follow‐up of 29.2 months. A total of Forty‐two patients in the IPR + EER group completed a mean follow‐up of 25.7 months. All incisions healed in stages. There were significant differences in Constant–Murley shoulder score, VAS score, and ROM before operation and at the final follow‐up in both groups (both P
