Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This research objective is to compare quadriceps strength by measuring maximal voluntary isometric contraction (MVIC) and risk of fall before and after subsartorial femoral triangle block (SSFTB)

Group Type EXPERIMENTAL

SSFTB

Intervention Type PROCEDURE

Patients who underwent major knee surgery and had already planned to perform subsartorial femoral triangle block (SSFTB) were included in the study. They were measured the outcomes the night before surgery. The saphenous nerve and nerve to vastus medialis were blocked at the subsartorial femoral triangle level by experienced anesthesiologists. After standard monitor, the distal femoral triangle was identified 2 cm proximal to the opening of adductor canal by ultrasound guidance. At this level, The location of nerve to vastus medialis was confirmed by nerve stimulator and it was blocked with 0.5% levobupivacaine 5 ml. Then, 0.5% levobupivacaine 10 ml would be injected perifemoral artery. The outcomes were re-assessed 30 min after block.
