Multi-modal, pre-emptive analgesia decreases the length of hospital stay following total joint arthroplasty.

Traditional treatment of pain following total joint arthroplasty involves postoperative oral narcotic medications and intravenous patient-controlled analgesia, both of which can result in significant postoperative morbidity. Multi-modal analgesia involving >or=2 classes of drugs acting on different receptor types may be as effective as single-narcotic/patient-controlled analgesia with fewer analgesic-related side effects. In addition, administering analgesia prior to surgery (pre-emptive) may reduce postoperative pain intensity.
