Abstract

Background: The aim of our study is to report the clinical and radiological outcomes of a series of prospectively
enrolled patients who have had double-row transosseous equivalent rotator cuff repairs, where all-suture anchors
were used as medial-row anchors, with a minimum follow-up of 1 year.
Methods: Twenty-two consecutive patients underwent arthroscopic transosseous equivalent double-row rotator
cuff repair using all-suture anchors as medial-row anchors. Oxford Shoulder Score, Constant Score and Visual
Analogue Scale pain score, together with shoulder range of motion, were used preoperatively and at 3 months, 6
months and final follow-up. Radiological evaluation was performed with magnetic resonance imaging at one-year
post surgery to assess the structural integrity of the repair and the rate of cyst formation in greater tuberosity.
Results: The patient mean age was 61 years (range 46-75). Minimum follow-up was 1 year, and the mean final
follow-up was 15 months (range 12-24). Healing failure in our patients was less than 5% (1/22 patients). There were
significant improvements in shoulder function outcome scores at final follow-up. The Constant and Oxford scores
were 78 and 44 at final follow-up respectively. There were similar magnitudes of improvement in range of motion
(combined abduction and rotation), pain score and supraspinatus strength at final follow up. The improvements
in outcome scores were already statistically significant at 3 months (p <.001). Using Kim’s classification for cyst
formation on T2-weighted MRI images, we observed no fluid or minimal fluid collection in 85% of the patients (17/22
patients). There were no correlations between the grade of bone changes and the clinical outcomes.
Conclusion: It is safe to use all-suture anchors as medial-row anchors when performing double-row anchor
transosseous equivalent rotator cuff repairs. The purported advantages of all-suture anchors may outweigh their
perceived disadvantages in rotator cuff repair surgery.
