Objective To explore the technique and effect of arthroscope-assisted rotator cuff repair via a small incision approach. Methods From March 2008 to December 2011, 22 cases of rotator cuff tear were treated by arthroseope-assisted repair with a small incision, including 16 of full-thickness rotator cuff tear and 6 of partial-thickness rotator cuff tears.
