The addition of peripheral nerve blocks to routine spinal or general anesthesia was associated with decreased risks of major adverse events after total hip or knee arthroplasty: A retrospective, propensity score-matched cohort study

Although total joint arthroplasty is the most effective procedures for end-stage arthritis, the incidence of postoperative death and complications remains high. The association of additional peripheral nerve blocks (PNBs) to routine spinal or general anesthesia with major adverse events (including mortality and complication rates) in elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) has been subject to inconclusive findings.
