Design outcomes

Primary

Measure	Time frame
To compare the analgesic efficacy of dual subsartorial block and adductor canal block with local infiltration analgesia for complete pain relief using the postoperative visual analog scale in patients undergoing total knee arthroplasty.Timepoint: 6 hrly for first 24 hours and 12 hourly till 72 hours postoperatively)	—

Secondary

Measure	Time frame
1. To measure the operated limb strength between groups using Medical Research Council scale every six hourlyTimepoint: 6 hrly for first 24 hours and 12 hourly till 72 hours postoperatively);2. To find the timing of first rescue analgesic and calculate total postoperative tramadol consumption between groupsTimepoint: Till 72hrs;3. To determine the sensory duration of the block.Timepoint: Till discharge;4. To map the site of postoperative knee pain and character of pain .Timepoint: Till discharge;6. Time to ambulation in the postoperative period.Timepoint: Till discharge;o determine the total postoperative length of hospitalization.Timepoint: Till discharge;To determine patient’s overall satisfaction score at discharge using 0-5 scoreTimepoint: At discharge	—
