Objective. The objective of the present study is to utilize a national database to examine the association between obesity and postoperative complications after primary Achilles tendon repair. Methods. The PearlDiver database was queried for patients undergoing primary Achilles repair using CPT 27650. Excision of a Haglund’s deformity or tendon transfer were exclusion criteria. Patients were then divided into obese (body mass index [BMI] > 30 kg/m2) and nonobese (BMI < 30 kg/m2) cohorts using ICD-9 codes. Complications within 90 days postoperatively were assessed using ICD-9 and CPT codes. Results. In all, 18 948 patients who underwent primary Achilles tendon repair were identified from 2005 to 2012. Overall, 2962 patients (15.6%) were coded as obese or morbidly obese. Obese patients had significantly higher rates of postoperative wound complications (odds ratio [OR] = 2.1; P < .0001), infection (OR = 1.8; P < .0001), venous thromboembolism (VTE; OR = 1.8; P = .001), and medical complications (OR = 3.9; P < .0001) compared with nonobese patients after primary Achilles tendon repair. Additionally, obese patients had a significantly lower rate of ankle stiffnesassociated with a significantly higher risk of s (OR = 0.4; P < .0001) compared with nonobese patients. Conclusion. Obesity is associated with a significantly higher risk of wound complications, infection, VTE, and medical complications after primary Achilles tendon repair.
