Single-row and double-row suture method are commonly used in the rotator cuff repair. Previous studies have shown that, double-row suture is not better than single-row suture in clinics.OBJECTIVE:
To compare clinical outcomes of single-row suture and double-row suture for rotator cuff repair, and evaluate the difference of therapeutic efficacy between two methods.METHODS:
A computer-based search was performed in the Medline (from January 2003 to February 2014), EMBASE (from January 2003 to February 2014) and Cochrane library (February 2014). According to the inclusion and exclusion criteria, all the randomized controlled studies addressing the outcome of single-row repair and double-row repair techniques were included in this meta-analysis. The methodological quality of each study was judged and a meta-analysis was conducted using Revman5.0. The preoperative and postoperative differences between the Constant score, American Shoulder and Elbow Surgeons (ASES) score, University of California, Los Angeles (UCLA) score, the re-rupture rate and the muscle strength were compared. The forest chart was used to compare the data between two groups, and the funnel plot was finished to detect the publication bias.RESULTS AND CONCLUSION:
A total of 10 randomized controlled trials (Levels I, II) were included. Meta-analysis showed that, there was no statistically significant difference in the Constant, ASES and UCLA scores in the double-row group and the single-row group before and after treatment. In the postoperative follow-up, double-row group had a lower re-rupture rate and a higher abductor muscle strength than single-row group. When the rotator cuff tear was less than 3 cm, double-row group had no significant difference with the single-row suture group. While in the over 3-cm tear group, double-row group showed better results than the single-row suture group on the Constant scpre, ASES score and UCLA score. Double-row suture has a low re-rupture rate than single-row suture in rotator cuff injury, and could achieve better abduction muscle strength. There is no significant difference in the functional score between double-row suture and single-row suture in the rotator cuff tear of less than 3 cm, while in the over 3-cm tear, double-row suture could achieve better functional score.Subject headings:
