Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients scheduled to undergo total knee arthroplasty will receive motor sparing knee blocks with continuous adductor canal block along with multimodal analgesia started pre-operatively and continued into the postoperative period. The study will evaluate the feasibility of home discharge within the first 24 hours following total knee arthroplasty. We will also evaluate the pain scores in the first 5 days following the surgery, causes of delayed discharge and any adverse events.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.
