Significant Increase in Early Reoperation After Latarjet-Bristow Procedure Versus Arthroscopic Bankart Repair for Anterior Shoulder Instability: A Propensity-Score Matched Analysis

Purpose: To compare the 30-day outcomes, including length of stay, short-term complications, hospital readmission, all-cause reoperation, and death after arthroscopic Bankart (AB) and Latarjet. Methods: Patients in the National Surgical Quality Improvement Program database who had undergone either AB or Latarjet-Bristow (LB) procedures for anterior shoulder instability from 2012 to 2018 were identified using Current Procedural Terminology codes. Nearest neighbor propensity score matching was used to address any potential demographic differences. The 30-day incidence of postoperative complications were compared, and univariate and multivariate logistic regressions were used to identify risk factors associated with the incidence of post-operative complications. Results: A total of 7,519 patients were identified, with 6,990 (93.0%) undergoing AB and 529 (7.0%) LB. After propensity score matching, the baseline demographics were not significantly different (P > .05). There was no significant difference in rate of total adverse events between the AB and LB cohorts (P = .06). There was a significant difference in the rate of return to the operating room between LB (1.9%) when compared to AB (0%) (P < .001). Of reoperations, 40% were due to need for revision stabilization (0.8% of all LB cases) and 40% were for irrigation and debridement. There was also a significant difference in operative time (AB = 87 minutes, LB = 131 minutes; P < .0001). Conclusions: Overall 30-day complication rates were low for both groups, with similar rates among AB and LB patients. However, there was a statistically significant increased rate of short-term reoperation or revision stabilization in the LB cohort. Level of Evidence: Level III, retrospective comparative prognostic trial.
