Arms of the Study
Arm 1
Experimental
Adductor canal block
The study is an open label pilot study to determine the feasibility of same day discharge following total knee arthroplasty with the use of a fast track regimen employing motor sparing knee blocks. The study will be performed on 25 American Society of Anesthesiologists class (ASA) 1-2 patients satisfying the inclusion criteria and undergoing unilateral primary total knee arthroplasty. First and second patients of the day undergoing surgery between Monday to Thursday in a week will be accessed for the study.
