Knotless All-Suture, Soft Anchor Bankart Repair Results in Excellent Patient-Reported Outcomes, High Patient Satisfaction, and Acceptable Recurrent Instability Rates at Minimum 2-Year Follow-Up.

PURPOSE

To evaluate minimum 2-year outcomes after arthroscopic knotless all-suture soft anchor Bankart repair in patients with anterior shoulder instability.

METHODS

This was a retrospective case series of patients who underwent Bankart repair using soft, all-suture, knotless anchors (FiberTak anchors) from 10/2017 to 06/2019. Exclusion criteria were concomitant bony Bankart lesion, shoulder pathology other than that involving the superior labrum or long head biceps tendon, or previous shoulder surgery. Scores collected preoperatively and postoperatively included SF-12 PCS, ASES, SANE, QuickDASH, and patient satisfaction with various sports participation questions. Surgical failure was defined as revision instability surgery or redislocation requiring reduction.

RESULTS

A total of 31 active patients, 8 females and 23 males, with a mean age of 29 (range: 16-55) years were included. At a mean of 2.6 years (range: 2.0-4.0), patient-reported outcomes significantly improved over preoperative levels. ASES score improved from 69.9 to 93.3 (P < .001), SANE improved from 56.3 to 93.8 (P < .001), QuickDASH improved from 32.1 to 6.3 (P < .001) and SF-12 PCS improved from 45.6 to 55.7 (P < .001). Median patient postoperative satisfaction was 10/10 (range: 4-10). Patients reported a significant improvement sports participation (P < .001), pain with competition (P = .001), ability to compete in sports (P < .001), painless use of arm for overhead activities (P = .001), and shoulder function during recreational sporting activity (P < .001). Postoperative shoulder redislocations were reported in 4 cases (12.9%)-all after major trauma-with 2 patients progressing to Latarjet (6.45%) at 2 and 3 years postoperatively. There were no cases of postoperative instability without major trauma.

CONCLUSIONS

Knotless all-suture, soft anchor Bankart repair resulted in excellent patient-reported outcomes, high patient satisfaction, and acceptable recurrent instability rates, in this series of active patients. Redislocation after arthroscopic Bankart repair with a soft, all-suture anchor only occurred after return to competitive sports with new high-level trauma.
