Clinical outcome of arthroscopic SLAP repair: conventional vertical knot versus knotless horizontal mattress sutures.

Purpose: Arthroscopic repair of type II superior labrum anterior to posterior (SLAP) tears yields variable results. In this study, the clinical outcomes of arthroscopic knotless horizontal mattress repair were compared to those of conventional vertical knot repair.

Methods: Forty-six patients treated arthroscopically for isolated SLAP lesions were assessed.
