Single-Rowversus Double-Row arthroscopic rotator cuff repair: A retrospective study of clinical & functional outcome

The purpose of this study was to compare the short term clinical and functional outcome of arthroscopic rotator cuff repair with single-row and double-row anchorage techniques. A retrospective study was conducted from January 2016 to June 2017 for 73 patients (31 males and 42 females) with an average age of 60.10 ± 6.11 years (range 50–73) who underwent arthroscopic rotator cuff repair. Double-row repair (group A, n= 30, 14 males and 16 females) were compared with patients of single-row technique (group B, n= 43, 17 males and 26 females) and evaluated clinically for functional outcome using range of movements, UCLA score and VAS score preoperatively, and 12 months postoperatively. Statistical analysis was performed using t test. Significance was set at P < .05. There was no significant difference in postoperative UCLA score (group A=31.06±2.61, range 26–35 and group B=30.83±2.74, range 27–35; p=0.718) and VAS score (group A=1.1±0.54, range 0-2andgroup B=1.02±0.59, range 0–2; p=0.572) between two groups. The range of shoulder movements showed no significant difference between two groups;forward flexion(group A=135.33°±26.48°, range 90–160°and group B=129.53°±27.59°, range 90–160°; p=0.369), external rotation(group A=81.00°±13.22°, range 50–90°andgroup B=77.44°±13.64°, range 50–90°; p= 0.268) and abduction(group A=142.66°±19.64°, range 90–160°and group B=137.44°±23.51°, range 90–160°; p=0.306).No significant difference was found in clinical and functional outcome between double-and single-row rotator cuff repair at short term follow up.
