Design outcomes

Primary

Measure	Time frame
To compare the effect of addition of ultrasound guided genicular nerve block to anaesthetic techniques on postoperative pain in patients undergoing total knee replacement. Timepoint: To compare the effect of addition of ultrasound guided genicular nerve block to anaesthetic techniques on postoperative pain in patients undergoing total knee replacement. Pain will be assessed at 6 12 18 24 & 48 hourly postoperatively by an anesthesiologist	—

Secondary

Measure	Time frame
To compare the effect of addition of ultrasound guided genicular nerve blocks in patients undergoing total knee replacement on postoperative opioid requirement , ambulation & physiotherapyTimepoint: Post operative opioid consumption will be recorded during 0-6 hours, 6-12 hours,12-24 hours & 24-48 hours. Ambulation distance was measured in feet on day 0, day 1, day 2 and day 3. Proportion of patients receiving rescue analgesia in both groups will also be compared. Presence of motor weakness of quadriceps if any will be noted.	—
