Short-Term Complications Following Total Ankle Arthroplasty and Associated Risk Factors: A NSQIP Database Analysis.

INTRODUCTION: Total ankle arthroplasty (TAA) has become increasingly utilized over the past 20 years to treat osteoarthritis of the ankle. The efficacy and safety of this procedure has been previously reported, but relatively few studies have documented the risk of postoperative complications associated with TAA over the past 10 years. Thus, the aim of this study is to provide a current report on the safety of TAA, particularly in association with a number of preoperative risk factors. METHODS: A retrospective review of all patients in the American College of Surgeons National Surgical Quality Improvement Program database who underwent TAA between 2012 and 2018 was performed. A total of 1333 patients were included in this analysis. Penalized logistic regression to consider small numbers of the postoperative complications was used to identify factors associated with incidence of the complications. RESULTS: The rate of readmission and superficial wound infection were found to be 1.4% and 0.6%, respectively. Risk factors associated with a prolonged hospital stay were black race, Hispanic race, and smoking. Diabetes was associated with a significantly increased risk of readmission. Age, sex, body mass index, and steroid use were not associated with increased risk of postoperative complications. CONCLUSION: In this study, the rate of surgical site infection and readmission in TAA was found to be relatively low, compared to published data on total knee arthroplasty and total hip arthroplasty. Both race and smoking increase the risk of prolonged hospital stay, while diabetes increases the risk of readmission. LEVELS OF EVIDENCE: Level III, retrospective comparative trial.

Wound-Healing Issues Following Rotational Ankle Fracture Surgery: Predictors and Local Management Options.

Background. The incidence and risk factors of wound-healing complications following rotational ankle fracture surgery are well documented in the literature. However, there is a paucity regarding management options following these complications. The goal of this study was to provide a descriptive analysis of one surgeon's experience managing wound complications in patients who have undergone ankle fracture surgery. Methods. A total of 215 patients who were operatively treated for an unstable ankle were retrospectively identified. Patient demographics, medical histories, initial injury characteristics, surgical interventions, and clinical follow-up were collected. Twenty-five of these patients developed postoperative wound problems. Results. Of the original cohort of 215 patients, 25 (11.6%) developed wound-healing complications. Their average age was 53.6 ± 18.0 years; there were 12 males (48.0%). Connective tissue/inflammatory disease (odds ratio [OR] 3.9), cardiovascular disease (OR 3.6), and active smoking (OR 3.3) were associated with an increased likelihood of developing postoperative wound complications. With regard to injuries, open fractures (OR 17.9) had the highest likelihood of developing postoperative complications, followed by type 44-C (OR 2.8) and trimalleolar fractures (OR 2.0). Conclusion. Wound complications following open treatment of ankle fractures occurred with an incidence of 11.6% in this series, of which only about half required operative intervention. A third of wounds were managed by orthopaedics in conjunction with plastic surgery. Levels of Evidence: Level III: Retrospective comparative study.
