Background: Superior capsular release has been used to reduce tendon tension, especially in arthroscopic repair of large-to-massive rotator cuff tears. Some clinicians have used a more extensive release of capsules in arthroscopic cuff repair for adequate reduction of torn tendons to footprints.
Purpose: To explore the effects of additional posterior capsular release for superior capsular release in arthroscopic repair of large-to-massive rotator cuff tears.
