ABSTRACT
INTRODUCTION: Coronavirus disease 2019 (COVID-19) has resulted in a global pandemic with several hundred million infections worldwide. COVID-19 causes systemic complications that last beyond the initial infection. It is not known whether patients who undergo elective orthopaedic surgeries after COVID-19 are at increased risk of complications. The purpose of this study was to evaluate whether patients who undergo orthopaedic procedures after recent COVID-19 diagnosis are at increased risk of complications compared with those who have not had a recent COVID-19 diagnosis. METHODS: The TriNetX Research Network database was queried for patients undergoing elective orthopaedic surgeries from April 2020 to January 2022 in the following subspecialties: arthroscopic surgery, total joint arthroplasty, lumbar fusion, upper extremity surgery, foot and ankle (FA) surgery. Cohorts were defined by patients undergoing surgery with a diagnosis of COVID-19 from 7 to 90 days before surgery and those with no COVID-19 diagnosis 0 to 90 days before surgery. These cohorts were propensity-score matched based on differences in demographics and comorbidities. The matched cohorts were evaluated using measures of association analysis for complications, emergency department (ER) visits, and readmissions occurring 90 days postoperatively. RESULTS: Patients undergoing arthroscopic surgery were more likely to experience venous thromboembolism (VTE) (P = 0.006), myocardial infarction (P = 0.001), and ER visits (P = 0.001). Patients undergoing total joint arthroplasty were more likely to experience VTE (P < 0.001), myocardial infarction (P < 0.001), pneumonia (P< 0.001), and ER visits (P = 0.037). Patients undergoing lumbar fusion were more likely to experience VTE (P = 0.016), infection (P < 0.001), pneumonia (P < 0.001), and readmission (P = 0.006). Patients undergoing upper extremity surgery were more likely to experience VTE (P = 0.001) and pneumonia (P = 0.015). Patients undergoing foot and ankle surgery were more likely to experience VTE (P < 0.001) and pneumonia (P < 0.001). CONCLUSION: There is an increased risk of complications in patients undergoing orthopaedic surgery after COVID-19 infection; all cohorts were at increased risk of VTE and most at increased risk of pneumonia. Additional investigation is needed to stratify the risk for individual patients.
ABSTRACT
INTRODUCTION: Wide-awake local anesthesia no tourniquet (WALANT) presents a nonstandard anesthetic approach initially described for use in hand surgery that has gained interest and utilization across a variety of orthopaedic procedures. In response to operating room resource constraints imposed by the COVID-19 pandemic, our orthopaedic service rapidly adopted and expanded its use of WALANT. METHODS: A retrospective review of 16 consecutive cases performed by 7 surgeons was conducted. Patient demographics, surgical details, and perioperative outcomes were assessed. The primary end point was WALANT failure, defined as intraoperative conversion to general anesthesia. RESULTS: No instances of WALANT failure requiring conversion to general anesthesia occurred. In recovery, one patient (6%) required narcotics for pain control, and the average postoperative pain numeric rating scale was 0.6. The maximum pain score experienced was 4 in the patient requiring postoperative narcotics. The average time in recovery was 42 minutes and ranged from 8 to 118 minutes. CONCLUSION: The WALANT technique was safely and effectively used in 16 cases across multiple orthopaedic subspecialties, including three procedures not previously described in the literature. WALANT techniques hold promise for use in future disaster scenarios and should be evaluated for potential incorporation into routine orthopaedic surgical care.
