Comparison of arthroscopic single-row and double-row rotator cuff injury repair

Abstract

Objective To compare the clinical effect of single-row (SR) and double-row (DR)rotator cuff injury repair.Methods Twenty-three patients with rotator cuff injury were randomized into SR group(12 patients) and DR group (11 patients) by ranom digits table.Two anchors and simple sutures were applied in SR group,three anchors and medial mattress sutures were applied in DR group.Clinical function were compared after operation 24 months,included pain visual analogue scale (VAS) scores,Constant scores,American Shoulder and Elbow Surgeons (ASES) scores,University of California at Los Angeles (UCLA) scores,range of shoulder motion (anteflexion,adtorsion conclination,external rotation),operation time and patient's satisfaction were compared.Re-tear rate and clinical function were also analyzed.Results The operation time in SR group was shorter than that in DR group [(115.8 t25.0) min vs.(124.5 ± 19.7)min,P =0.033].The scores of VAS,Constant,ASES,UCLA in two groups had no significant difference (P ＞ 0.05).The full-thickness re-tear in SR group was 2 patients,in DR group was 2 patients,there was no significant difference (P ＞ 0.05).The full-thickness re-tear and part-thickness re-tear in SR group was 7 patients,in DR group was 2 patients,there was significant difference(P=0.041).Furthermore,the scores of VAS,Constant,ASES,UCLA had no significant difference (P＞ 0.05).Conclusion Compared with SR,2-5 cm rotator cuff injury repaired by DR has no obviously advantage.
