The Effect of Obesity on Achilles Rupture Repair.

Obesity is an increasingly common comorbidity that may negatively affect outcomes following orthopaedic surgery. It is valuable to determine whether obese patients are vulnerable for postoperative complications. The purpose of this study was to analyze data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) to determine the effect of obesity on surgical treatment of Achilles tendon ruptures.Patients who underwent a surgical repair of the Achilles tendon were retrospectively identified through the ACS NSQIP. The patients were divided into 2 cohorts (obese and nonobese), then perioperative and postoperative factors were evaluated for association with obesity.A total of 2128 patients were identified, of whom 887 (41.7%) were classified as obese. Obesity correlated with an increased operative time, 60.9 versus 56.1 minutes. The only postoperative complication associated with obesity was wound dehiscence. Logistic regression adjusted for comorbid conditions demonstrated that obesity was not associated with an increased risk of wound dehiscence.A large segment of the patient population undergoing Achilles tendon repair is obese. Obesity was found to have an increased association with wound dehiscence, likely related to comorbid conditions, following Achilles tendon repair. Obesity was not significantly associated with any other complication.III, Retrospective Cohort Study.
