Anterior Knee Nerves Block vs Femoral Nerve Block for Knee Arthroscopy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized, single-blind study, adults aged 18–65 undergoing elective knee arthroscopy under spinal anesthesia receive either an ultrasound-guided ANK block or a ultrasound-guided femoral nerve block before surgery. Both blocks use 20 mL of 0.25% bupivacaine, followed by standard spinal anesthesia and routine postoperative rescue analgesia. Pain scores, analgesic consumption, hemodynamics, and time to first mobilization are collected for up to 24 hours, with safety monitoring for block-related complications. The anesthesiologist performing the block is not blinded, but patients and outcome assessors are blinded to group assignment.
