Summary

Soft anchors are examined for arthroscopic treatment of traumatic anterior shoulder instability through clinical and radiological comparison of fixation materials and its found that there was no clinically and radiologically significant difference between metal anchor and soft anchor.

Abstract

Title: Are Soft Anchors Able to Meet Expectations in the Arthroscopic Treatment of Traumatic Anterior Shoulder Instability?
Abstract

Purpose

Purpose of this study is to investigate usability of soft anchors in arthroscopic bankart repair applied for anterior shoulder instability treatment through clinical and radiological comparison of fixation materials metal anchors and soft anchors.

Methods

51 patients, who received arthroscopic bankart repair procedure due to recurrent anterior shoulder instability, were retrospectively examined. In the first group, 24 patients with metal anchors were included, and 27 patients with soft anchors were included in the second group. Clinical results were evaluated with Rowe and Constant scores. Radiological assessment was performed with shoulder x-rays obtained in the post-surgical early stage and at the last control visit. Mann Whitney U Test was used for the comparison of two independent mean and median (p<0.05).

Results

Mean Rowe and Constant scores of first group were calculated as 913±8.0 and 87.9±6.1, respectively, and 91.9±12.0 and 88.9±8.4 respectively for the second group. No statistically significant difference was found (p=0.229, p=0.189). Mean follow-up duration of the first group was 39 months median (30-72) and 23 months median (18-39) for the second group, and statistically significant difference was found (p<0.001).

Conclusions

There was no clinically and radiologically significant difference between metal anchor and soft anchor use in arthroscopic treatment of anterior shoulder instability. However, it can be said that soft suture anchor use can meet expectations and can be a better option due to the potential problems related to metal anchors, such as articular cartilage damage in case of misplacement, presence of artifact effect when magnetic resonance imaging is required, difficulties encountered during the placement of the anchor and possibility to cause bone stock loss in case revision surgery is needed.
Key words: Arthroscopic bankart repair, metal anchor, soft anchor, traumatic anterior shoulder instability.
