Brief Summary:
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.

Arm Intervention/treatment
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.
Procedure: Adductor canal block
All patients will recieve fast tracking with reduced fasting times, multimodal analgesia and adductor canal block

Primary Outcome Measures :
  1. percentage of patients discharged at 23 hours based on a composite of various factors represented on a pre-determined criteria [ Time Frame: 24 hours ]

Secondary Outcome Measures :
  1. first 24 hour pain scores [ Time Frame: 24 hours ]
  2. first 96 hour pain scores [ Time Frame: 96 hours ]
  3. Rescue analgesic frequency [ Time Frame: 24 hours ]
  4. total analgesic usage in the first 24 and 96 postoperative hours [ Time Frame: 96 hours ]
