Analysis of Risk Factors, Complications, Reoperations, and Demographics Associated With Open and Arthroscopic Rotator Cuff Repair: An Analysis of a Large National Database.

Purpose: To assess the national trends in arthroscopic and open rotator cuff repair surgery and the associated demographics, complications, and risk factors specific to each procedure.

Methods: A retrospective cohort study was performed using the National Surgical Quality Improvement Program (NSQIP) dataset between the years 2007 and 2018. Patients were identified using Common Procedural Terminology codes for open and arthroscopic rotator cuff repair. Variables collected including basic demographics, procedural, and outcome specific variables as available through the NSQIP repository. Appropriate statistical measures were used to compare the groups, with the χ test used for categorical variables and t test for continuous variables.

Results: The arthroscopic cohort comprised 39,013 patients; the open group consisted of 8,664. Reported arthroscopic and open cases increased significantly between 2007 and 2018 from 135 to 7,269 and 65 to 1,168, respectively. Average operative time for arthroscopic procedure was 89 minutes and 76 minutes for open. The open group consisted of a slightly greater percentage of smokers, 18.3% versus 15.2%, and patients with diabetes, 18.2% versus 15.9%, both of which were statistically significant (P < .001). Open cases had an odds ratio of 3.05 for superficial infections and 7.40 for deep infections, both of which were statistically significant (P < .001). The open cohort also had an odds ratio of 1.71 for unplanned readmissions when compared with the arthroscopic cohort, which was also statistically significant (P < .001).

Conclusions: According to the NSQIP database, the increase in arthroscopic procedures is significantly outpacing the increase in open procedures during this study period, which matches the trends seen in previous studies. Patients with diabetes and who smoke also represent a greater risk group for postoperative complications when undergoing open surgery. These findings suggest that perhaps the decision to pursue one technique over the other may be influenced both by provider preference and patient-related factors.

Level Of Evidence: III, retrospective comparative trial.
