This study is a prospective, randomized, double-blinded, placebo-controlled study of the drug colchicine in the acute postoperative period for patients who are undergoing a total knee arthroplasty (TKA). Patients aged 18 years or older who are undergoing TKA will be invited to participate in the study. The primary endpoint of this study is to determine if colchicine, an anti-inflammatory medication commonly used for gout attacks, will decrease the postoperative pain of patients undergoing elective TKA.
