Summary

This study tested two types of nerve blocks to control pain after total knee replacement. 62 patients received either a new para-sartorial block or a standard femoral-sciatic block. The goal was to see which provides better pain relief with less muscle weakness. Results will help doctors choose the best option for recovery.
