Study finds, difference between Increased acromiohumeral dis
Researchers aim to compare the effects of double- and single-row arthroscopic rotator cuff repairs (ARCR) on repair integrity (RI) and acromiohumeral distance (AHD). Arthroscopic rotator cuff surgery is an effective treatment for rotator cuff tears with the considered use of double-row repair techniques.

In this observational study, 98 patients with degenerative rotator cuff tear treated with arthroscopic rotator cuff repair were retrospectively identified. 43 patients who had ARCR for full-thickness cuff tear and clinical, radiologic follow-up were included. Of these 43 patients, 23 were grouped as double-row repair group (DRG) and 20 as single-row repair group (SRG).

A minimum of 12 months after the surgery, bilateral shoulder MRIs were obtained. Contralateral shoulders without asymptomatic rotator cuff tears served as a control group (CG). The operating surgeon and two other surgeons experienced in arthroscopy blindly measured the AHD and determined the RI at the control MRIs in all groups.

--The mean age was 57.89 years, and the mean follow-up time was 28,65 months.

--The mean AHD of the CG was 9.7 ± 0.96 mm, the preoperative AHD of DRG was 8.62 ± 1.45 mm, and SRG was 9.71 ± 0.95 mm.

--The postoperative mean AHD of DRG 9.61 ± 1.83 mm and SRG was 10.21 ± 1.97 mm.

--AHD differences between the preoperative and postoperative groups were significant.

--The increase of the AHD in the double-row group was significantly higher than the single-row group.

--There was a high correlation between the RI and DASH scores. RI did not correlate with the repair method.

Finally, whereas double-row repairs in the clinical context can retain a higher AHD than single-row restorations, this differential has no impact on functional performance. Functional findings are favorable if RI is obtained regardless of the surgical procedure.
