Arthroscopic and Open or Mini-Open Rotator Cuff Repair Trends and Complication Rates Among American Board of Orthopaedic Surgeons Part II Examinees (2007-2017).

Purpose: To ascertain trends and reported complication rates of arthroscopic and open or mini-open rotator cuff repairs (RCRs) reported by American Board of Orthopaedic Surgery (ABOS) Part II examinees between 2007-2017.
Methods: The ABOS database was queried for both arthroscopic RCR (International Classification of Diseases code 29827) and open or mini-open RCR (International Classification of Diseases codes 23410 and 23412) performed by Part II examinees from 2007-2017. A comparison between overall procedure rates, as well as reported complications (anesthetic, medical, surgical, reoperations, and readmissions) associated with the respective repair technique, was performed.
Results: From 2007-2017, a total of 31,907 RCRs were reported by Part II examinees. Of those, 85.2% (n = 27,189) were arthroscopic whereas 14.8% (n = 4,718) were open or mini-open. The rate of arthroscopic RCR increased from 73% (n = 2,138) in 2007 to 90% (n = 2,031) in 2017, whereas the rate of open or mini-open RCR decreased from 27% (n = 771) to 10% (n = 234) during the same period. Rates of reported annual complications were significantly lower for arthroscopic RCR (7.4%-16.2%) than for open or mini-open RCR (12.9%-30.3%) for each of the past 6 years (2012-2017) (P < .001). Arthroscopic RCR had an overall lower cumulative occurrence of complications than open or mini-open RCR over the past decade (2007-2017) (P < .001). The relative risk of complications for arthroscopic RCR compared with open RCR was 0.71 (95% confidence interval, 0.66-0.77).
Conclusions: ABOS Part II examinees reported an increased practice of arthroscopic RCR in comparison with open or mini-open RCR over the past 10 years. Reported annual complication rates have been significantly lower for arthroscopic RCR over the past 6 years, with an overall lower cumulative rate from 2007-2017.
Level of Evidence: Level III, retrospective cohort study.
