Biomechanical comparison of 3 suture anchor configurations for repair of type II SLAP lesions.

Abstract Our purpose was to compare 3 commonly used suture anchor configurations for repair of type II SLAP lesions.

METHODS: Biomechanical testing was performed on 3 groups of 7 cadaveric shoulders by use of an optical linear strain measurement system. Standardized type II SLAP lesions were created and repaired via 3 suture anchor configurations: (1) a single simple suture anterior to the biceps; (2) two simple sutures, one anterior and one posterior to the biceps; and (3) a single mattress suture through the biceps anchor. Cyclic traction was applied to the biceps tendon, and strain failure (defined as 2 mm of permanent displacement), yield, and pullout loads were measured.
