Arthroscopic Biceps Transfer to the Glenoid With Bankart Repair Grants Satisfactory 2-Year Results for Recurrent Anteroinferior Glenohumeral Instability in Subcritical Bone Loss

Arthroscopy. 2022 Jun;38(6):1766-1771. doi: 10.1016/j.arthro.2021.11.043. Epub 2021 Dec 7.


Purpose: To evaluate the short-term outcomes of the arthroscopic dynamic anterior stabilization (DAS), which is a transfer of the intra-articular portion of the long head biceps through the subscapularis split and fixation on the anterior glenoid, combined with a Bankart repair.

Methods: A retrospective evaluation was performed of DAS and a minimum of 2-year follow-up. Inclusion criteria were the presence of anteroinferior instability, a positive apprehension test at 90° of abduction and external rotation, and subcritical glenoid bone loss (less than 20%). Exclusion criteria were severe (≥20%) glenoid bone loss, presence of biceps lesions or rupture (spontaneous or biceps tenotomy), pre-existing glenohumeral osteoarthritis, multidirectional or voluntary instability, previous arthroscopic stabilization procedure, and epilepsy. Outcomes included the Rowe score, range of motion (ROM), and recurrence.

Results: Twenty-three patients were treated with DAS and arthroscopic Bankart repair during the study period. One person was lost to follow-up, leaving 22 patients available at last follow-up. Those 22 patients had an average age of 31.9 ± 12.3 years (range, 18-68) and were evaluated at an average follow-up of 3.2 ± 0.7 years (range, 1.2-4.2). The Rowe score increased from 36.1 ± 16.2 (range, 10-70) preoperatively to 89.8 ± 20.1 (range, 30-100) postoperatively (P < .001) with almost all patients (90.9%) improving their score beyond the minimal clinically important difference of 9.7 points. Postoperatively, ROM was maintained. Three patients (13.6%) analyzed at final follow-up demonstrated recurrence, one was successfully treated conservatively, but two revised with a Latarjet. No postoperative Popeye deformity, biceps cramping, or other complication were reported.

Conclusions: The DAS procedure may be an option for augmentation of a Bankart repair in patients with anterior shoulder instability and subcritical bone loss. ROM is maintained without evidence of postoperative Popeye deformity or biceps cramping.

Level of evidence: Level IV, retrospective study.
