Clinical and sonographic evaluation of subpectoral biceps tenodesis with a dual suture anchor technique demonstrates improved outcomes and a low failure rate at a minimum 2-year follow-up.

Introduction: The purpose of this study was to evaluate the clinical outcomes and integrity of an open subpectoral biceps tenodesis using a dual suture anchor construct.

Materials And Methods: Patients with at least 2 years of follow-up were retrospectively evaluated for simple shoulder test (SST), American Shoulder and Elbow Surgeons (ASES) score, and visual analog scales (VAS) for pain, function and satisfaction. A physical exam assessed shoulder range of motion and elbow strength. Ultrasonography visualized construct integrity.

Results: Of 43 eligible patients, 36 completed questionnaire evaluation and 22 completed an additional physical examination. Indications included superior labral anterior-posterior (SLAP) lesions (4), partial thickness tears (6), instability (6), and tenosynovitis of the biceps tendon (20). Eighteen patients (50%) had an associated rotator cuff tear. Patient-reported outcomes improved pre- vs postoperatively: ASES score (45.4 vs 78.6, P < 0.001), SST (5.1 vs 9.6, P < 0.001), pain-VAS (4.8 vs 2.0, P < 0.001), and function-VAS (4.9 vs 2.3, P < 0.001). Satisfaction-VAS was 8.3 postoperatively. Patient-reported outcomes did not differ for patients with an associated rotator cuff tear compared to those without (P ≥ 0.427). None of the physical exam measures were lower on the operative side compared to the healthy side (P ≥ 0.516). Sonographic evaluation revealed preserved integrity of the tenodesis construct in all cases. No complications were noted.

Conclusions: Subpectoral biceps tenodesis utilizing a dual suture anchor technique is a treatment option for SLAP lesions, partial thickness tears, subluxation, and tenosynovitis of the long head of the biceps with high rates of postoperative patient satisfaction, a low failure rate, and improved outcome scores. The presence of a concomitant rotator cuff tear did not influence clinical outcomes.
