Pain management in total joint arthroplasty: a historical review.

Abstract

Patients undergoing total hip and knee arthroplasty experience substantial and sustained postoperative pain. Inadequate analgesia may impede recovery and delay hospital discharge. Traditionally, postoperative analgesia following arthroplasty was provided by intravenous patient-controlled analgesia or epidural analgesia, but each technique has distinct advantages and disadvantages. Recently, peripheral nerve blockade of the lumbosacral plexus has emerged as an alternative analgesic approach. An increasing number of studies have reported multimodal analgesia featuring unilateral peripheral block provide pain relief and functional outcomes similar to that of continuous epidural and superior to systemic analgesia but with fewer side effects. This review discusses the indications, benefits, and side effects associated with conventional and innovative analgesic approaches to facilitate rehabilitation and improve outcome following total joint arthroplasty.
