 Arthroscopic capsular release was used to treat 30 patients with frozen shoulder. None of the patients had a trauma history, including shoulder fractures. Arthrography revealed reduced joint volume, but magnetic resonance imaging showed no evidence of rotator cuff tears. Capsular release was performed via anterior, posterosuperior, and posteroinferior (PI) working portals. The PI working portal was gradually enlarged by using the step cannulation system to avoid injuring the axillary nerve. The minimum follow-up period was 12 months. The average UCLA score was 10.4 points before surgery and 32.2 points at the final follow-up examination. Range of motion before surgery yielded the following average values:elevation 73 degrees;external rotation of the arm at the side, 13.4 degres;and internal rotation to the 2nd lumbar vertebra;versus 152 degrees, 55.4 degrees, and to the 10.2nd thoracic vertebra at the final follow-up examination. No complications were observed when the step cannulation system was used.
