Summary

This study compares two ultrasound-guided nerve block methods for controlling pain after knee surgery: an adductor canal block combined with infiltration of the back of the knee (IPACK) versus a 4-in-1 block. Researchers measure pain scores, how much extra pain medication is needed, and how long pain relief lasts. The goal is to find which technique provides better pain control and recovery.
