Biceps Tenodesis Versus Tenotomy in the Treatment of Lesions of the Long Head of the Biceps Tendon in Patients Undergoing Arthroscopic Shoulder Surgery: A Prospective Double-Blinded Randomized Controlled Trial.

BACKGROUND

The biceps tendon is a known source of shoulder pain. Few high-level studies have attempted to determine whether biceps tenotomy or tenodesis is the optimal approach in the treatment of biceps pathology. Most available literature is of lesser scientific quality and shows varying results in the comparison of tenotomy and tenodesis.

PURPOSE

To compare patient-reported and objective clinical results between tenotomy and tenodesis for the treatment of lesions of the long head of the biceps brachii.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

Patients aged ≥18 years undergoing arthroscopic surgery with intraoperative confirmation of a lesion of the long head of the biceps tendon were randomized. The primary outcome measure was the American Shoulder and Elbow Surgeons (ASES) score, while secondary outcomes included the Western Ontario Rotator Cuff Index (WORC) score, elbow and shoulder strength, operative time, complications, and the incidence of revision surgery with each procedure. Magnetic resonance imaging was performed at postoperative 1 year to evaluate the integrity of the procedure in the tenodesis group.

RESULTS

A total of 114 participants with a mean age of 57.7 years (range, 34 years to 86 years) were randomized to undergo either biceps tenodesis or tenotomy. ASES and WORC scores improved significantly from pre- to postoperative time points, with a mean difference of 32.3% (

CONCLUSION

Tenotomy and tenodesis as treatment for lesions of the long head of biceps tendon both result in good subjective outcomes but there is a higher rate of Popeye deformity in the tenotomy group.
