No Difference in Clinical Outcomes for Arthroscopic Suprapectoral Versus Open Subpectoral Biceps Tenodesis at Midterm Follow-up: A Randomized Prospective Analysis

Abstract

Background: We have previously reported the 1-year outcomes of arthroscopic suprapectoral biceps tenodesis (ASPBT) versus open subpectoral biceps tenodesis (OSPBT) for the management of long head of the biceps tendon (LHBT) pathology. While patients had similar 1-year biceps muscle strength and pain, longer-term functional outcomes are unknown. Purpose: To directly compare clinical outcomes of ASPBT versus OSPBT with interference screw fixation, distal to the bony bicipital groove, at a minimum of 2 years’ follow-up. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 85 patients undergoing biceps tenodesis (BT) for LHBT disease were randomized into the ASPBT or OSPBT group. Both techniques utilized polyether ether ketone inference screws for tenodesis fixation. Patients completed American Shoulder and Elbow Surgeons (ASES), Constant subjective, and Single Assessment Numeric Evaluation (SANE) questionnaires preoperatively and again at 6 months, 12 months, and at the final follow-up at a minimum of 24 months. Results: A total of 73 patients (37/42 randomized to ASPBT [88%]; 36/42 randomized to OSPBT [86%]) with a mean age of 50.4 ± 10.3 years and a mean body mass index of 29 ± 7.9 were included in clinical outcome analyses. The mean final follow-up was 2.9 years (ASPBT, 3 years; OSPBT, 2.8 years [range 2-5.2 years]). Comparison of demographic characteristics and intraoperative findings showed no significant differences in age, sex, concomitant procedures, and rotator cuff disease. No statistically significant differences in the ASES (P =.25), Constant subjective (P =.52), and SANE scores (P =.61) were found at the final follow-up. Clinical outcomes scores showed no significant improvement from a mean of 12.6 months to the final follow-up at 34.5 months (ASPBT: ASES, P =.43; Constant, P =.25; SANE, P =.45 vs OSPBT: ASES, P =.65; Constant, P =.78; SANE, P =.70). No patients required revision of BT in either group. Conclusion: This study reported a minimum of 2-year follow-up of patients undergoing ASPBT or OSPBT, utilizing the same interference screw technique, for the management of LHBT pathology in the setting of concomitant shoulder procedures. There were no significant differences in patient-reported outcomes and complication rates found at any time point. Registration: NCT02192073 (ClinicalTrials.gov identifier).
