Evaluating the Effect of Rotator Cuff Repair With Concomitant Distal Claviculectomy on 2 and 4 Year Reoperation Rates.

Background: The current literature has differing views on the efficacy of concomitant distal claviculectomy (DC) during rotator cuff repair (RCR) in preventing revision surgery. Our aim was to investigate the revision surgery rate between RCR with DC and RCR without DC.

Methods: A retrospective cohort analysis was conducted using a national claims database. Patients undergoing open or arthroscopic primary RCR with or without concomitant DC were identified. The primary outcome was 4-year revision surgery rates. Univariate analysis was conducted using chi-square or Student t tests. Multivariable analysis was conducted using logistic regression, and an adjusted number needed to harm was calculated.

Results: A total of 131,232 patients met inclusion criteria. After logistic regression, patients undergoing RCR with DC had higher odds of requiring a subsequent DC procedure [OR; 95% CI; P-value (1.49; 1.35-1.64; P < 0.001)] but lower odds of any revision surgery (0.87; 0.80-0.91; P < 0.001) within 4 years than those who underwent RCR without DC.

Conclusion: Although associated with a lower rate of overall revision surgeries within 2 and 4 years of RCR, those who underwent RCR with DC were 85% more likely at 2 years and 49% more likely at 4 years to undergo revision surgery of the distal clavicle than those without concomitant DC.
