[Clinical results in arthroscopic rotator cuff repair with the modified Mason-Allen technique].

Introduction: rotator cuff tears are one of the most common shoulder injuries. The treatment of choice is arthroscopic repair with the use of anchors. The modified Mason-Allen technique, which combines the benefits of suture bridge and mattress sutures, has shown satisfactory results. This study aims to report and analyze the clinical results using these suture techniques in rotator cuff tears.

Results: preoperative mean active flexion 126o, 169o at three months, 175o at 12 months (p < 0.0001), active abduction 98o, 159o at three months and 167o at 12 months (p < 0.0001), internal rotation preoperative value 4.4 ± 3, at three months 7.1 ± 1.7 (p < 0.05) and 12 months 7.6 ± 1.1 (p < 0.001). Constant score 45.76 ± 16.35 (p < 0.0001) at three months 87.27 ± 10.94 and 12 months 91.30 ± 6.00. SSV 41.30 ± 20.89, three months 81.43 ± 18.31 and 12 months 94.37 ± 6.90 (p = 0.0001). Initial mean VAS 6.6 ± 1.6 and 12 months 0.63 ± 1.02 (p < 0.0001).

Conclusion: in rotator cuff tears, using a single row with the modified Mason-Allen technique is a recommended and replicable option with satisfactory results and statistically significant clinical improvement at three and 12 months post-surgery.
