Abstract

Objective To diagnose risk factors for the development of local or medical postoperative complications up to 30 days after surgery in patients undergoing total knee arthroplasty Methods The present analysis included all patients who underwent knee arthroplasty performed in this hospital during the study period, based on data from medical records of the patients, with the aim of investigating factors related to the occurrence of local or medical complications during hospitalization and up to 30 days after the procedure, if they needed any additional intervention. Results Out of the 157 patients included in the study, 17.1% had some complication. The most prevalent were arthrofibrosis (6.4%), deep infection (4.4%), and superficial infection (2.5%), among others. Older patients and a greater number of previous comorbidities were associated with a higher risk of postoperative complications. Conclusions Older patients and a greater number of comorbidities were related to an increased risk of postoperative complications. The American Society of Anesthesiologists (ASA) score proved to be insufficient to assess the occurrence of complications after knee arthroplasty and new tools should be used for this purpose.
