Evaluation of patients undergoing rotator cuff suture with the modified mason-allen technique.
OBJECTIVE
: The purpose of this study was to clinically evaluate patients who underwent Arthroscopic Rotator Cuff Repair (RC) using the Modified Manson-Allen technique.


METHODS
: We evaluated 79 patients who underwent shoulder arthroscopy. The lesions were repaired using the modified Mason-Allen suture between 2003 and 2009, divided by Cofield classification and clinically evaluated by the scoring system of the University of Los Angeles (UCLA) in the pre- and postoperative periods.


RESULTS
: The evaluation of lesion sizes showed 7 small lesions (<1cm), 55 average lesions (1-3cm) and 17 large lesions (3-5cm), and in this last group there were 5 reruptures and the patients were reoperated by the same technique. Comparing the pre (14.1) and postoperative (32.6) values by UCLA system there was a significant improvement of score (142.3%), regardless of lesion size. The modified Mason-Allen suture provided satisfactory clinical results, regardless of lesion size, similar to those found in literature. The rerupture rate was high in large lesions. New suture techniques have been developed with the aim of reducing the incidence of rerupture.


CONCLUSIONS
: The modified Mason-Allen suture technique provided clinical improvement, regardless of lesion size. Level of Evidence IV, Cases Series .
