Design outcomes

Primary

Measure	Time frame
To compare the analgesic efficacy of intermittent bolus versus continuous infusion of Ropivacaine in adductor canal block using Numerical Rating scaleTimepoint: Pain shall be assessed at 0,4,8,12,24 hours and 0.25% Ropivacaine 20ml shall be given in adductor canal if Numerical Rating Scale is more than 3 at any given time.	—

Secondary

Measure	Time frame
To compare the motor block between the two groups using the Modified Bromage scale Timepoint: The patients will be assessed for motor blockade every 6 hours interval for 24 hours postoperatively by the Modified Bromage Scale.;To compare the total amount of Ropivacaine consumed between the study groupsTimepoint: Amount of Ropivacaine consumed during the observation period of 24hours is calculated in milligrams	—
