Cognitive impairment and postoperative outcomes in patients undergoing primary total hip arthroplasty: A systematic review

摘要

Study objective: Total hip arthroplasty (THA) is a common surgical procedure in the elderly. Varying degrees of cognitive impairment (CI) are frequently seen in this patient population. To date, there has been no systematic review of the literature specifically examining the impact of CI on outcomes after elective THA. The aim of this systematic review was to identify studies that compare the postoperative outcomes of patients with and without CI after undergoing elective primary THA.
