Open Biceps Tenodesis Associated With Slightly Greater Rate of 30-Day Complications Than Arthroscopic: A Propensity-Matched Analysis

Abstract

To compare the early complication risk associated with open biceps tenodesis (OBT) and arthroscopic biceps tenodesis (ABT) and determine which preoperative factors may influence complication rate. The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively queried from 2008 to 2016 for all procedures with CPT codes for ABT (29828) and OBT (23430). Patients were excluded if they received concomitant rotator cuff repair or shoulder arthroplasty. Patients undergoing OBT and ABT were matched by propensity scores based on age, body mass index, operative time, proportion of smokers, and proportion of concomitant subacromial decompression, distal clavicle excision, SLAP, and debridement. The incidence of adverse events in the 30-day postoperative period was compared. A total of 8,032 patients met the inclusion and exclusion criteria. Prior to propensity match, patients receiving OBT and ABT, respectively, differed with respect to age (49.4 ± 13.8 vs 51.4 ± 13.2; P< .001), body mass index (29.6 ± 6.8 vs 29.9 ± 7.0; P= .029), and operative time (91.2 ± 51.3 vs 85.3 ± 43.4; P < .001). Following propensity match, 6,330 remained in the study (3,165 ABT and 3,165 OBT). OBT had significantly greater incidence of any adverse events (1.58% vs 0.95%; P= .032) and anemia requiring transfusion (0.35% vs 0%; P= .001). Multivariate analysis suggested that OBT (relative risk [RR]= 1.7, 95% confidence interval [CI], 1.1-2.7; P= .020), old age (RR= 1.6, 95% CI, 1.0-2.5), history of dyspnea (RR= 3.8, 95% CI, 1.8-7.7; P < .001), and congestive heart failure (RR= 5.5, 95% CI, 1.3-22.7; P= .019) were associated with developing a postoperative adverse event within 30days of surgery. Both procedures were found to have a low rate of complications, although OBT had a slightly greater (1.58% vs 0.95%) rate of 30-day complications than ABT. Early complication rate should not serve as impetus to direct surgical technique as number needed to treat is high, although ABT may be considered in more high-risk individuals.
