The aim of this study is To use a nationwide database to determine differences in cost between patients who underwent arthroscopic rotator cuff tear with open vs. arthroscopic biceps tenodesis (BT).

The 2014 State Ambulatory Surgical and Services Databases from 6 US states was utilized. All cases with CPT codes 29827 (arthroscopic rotator cuff repair [RCR]) and either 23430 (tenodesis of long tendon of biceps) or 29828 (arthroscopic BT) were selected. Cases that included both 23430 and 29828 were excluded, as were those missing demographic data. Generalized linear models were used to model costs based on the surgical and patient variables that were significant in the initial bivariate analysis (P < .05).

Results. A total of 3635 RCR and BT cases were identified. There were 2847 (78.3%) with arthroscopic BT and 788 (21.7%) with open BT. Patients undergoing arthroscopic BT were 3.1 years older than patients undergoing open BT (P < .001). For arthroscopic BT, 39.2% of the cases were women compared with 22.6% of the open cases (P < .001). Hence we conclude that Given that both techniques have been shown to be similarly effective in long-term follow-up, surgeons should be aware of opportunities for cost saving, particularly with the advent of bundled surgical reimbursements.
