A Comparative Study On Use of Two Versus Three Double-Loaded Suture Anchors in Arthroscopic Bankart Repair

Abstract

Objectives: This study aims to compare clinical results of repair using two versus three double-loaded suture anchors in arthroscopic Bankart repair.

Patients and methods: Between July 2012 and December 2017, a total of 40 patients (38 males, 2 females; mean age: 31.68.1; range: 17 to 47 years) who underwent Bankart arthroscopic surgery and were followed for minimum two years were retrospectively analyzed. Group 1 (n=17) underwent arthroscopic Bankart repair with two double-loaded suture anchors, while Group 2 (n=23) underwent repair with three double-loaded suture anchors. Clinical outcomes of the patients and recurrences were compared.

Results: At the final postoperative follow-up, a significant improvement was observed in the functional outcomes in all patients. No statistically significant difference was found (p>0.05) in the mean clinical scores of the Constant Shoulder Score between Group 1 (94.2 +/- 7.8) and Group 2 (95.4 +/- 4.1). There was no significant difference in the mean Rowe scores (Group 1: 95.6 +/- 4.6 vs. Group 2: 96.3 +/- 3.8, respectively) and external rotation loss (at neutral Group 1: 1.9 degrees vs. Group 2: 2.2 degrees, respectively). Three of our patients had recurrent dislocation during a major traumatic event (n=2 in Group 1 and n=1 in Group 2).

Conclusion: Our study results suggest that stability is not correlated with the use of either two versus three double-loaded suture anchors in arthroscopic Bankart repairs.
