The primary objective is to of this study is to evaluate the efficacy of perioperative dextromethorphan compared to placebo for postoperative pain in patients undergoing total knee arthroplasty (TKA). This is a single-institution, multi-dose, randomized, placebo-controlled, trial to evaluate the efficacy of perioperative dextromethorphan compared to placebo for postoperative pain in patients undergoing TKA. Male and/or female patients will be randomized to either dextromethorphan treatment group (n = 80) or placebo group (n= 80). Patients will receive 60 mg oral dextromethorphan (or matching placebo) preoperatively, as well as 30 mg 8- and 16-hours postoperatively.
