Brief Summary:
The purpose of this study is to establish the effect of sub-anesthetic dosing of ketamine with spinal anesthesia during total knee arthroplasty on post-operative pain and narcotic consumption. We hypothesize that sub-anesthetic ketamine will decrease post-operative pain and narcotic consumption and may secondarily lead to shorter lengths of stay, faster rehabilitation, improved postoperative outcomes and patient satisfaction.
