The Benefits of Intraoperative Small-Dose Ketamine on Postoperative Pain After Anterior Cruciate Ligament Repair

Abstract

We found that intraoperative small-dose ketamine reduced postoperative morphine requirements and improved mobilization 24 h after arthroscopic anterior ligament repair. No differences were observed in the timing of administration. Intraoperative small-dose ketamine may therefore be a useful adjuvant to perioperative analgesic management.
