Preop US-Guided Nerve Blocks for Pain & Recovery After Ankle Arthroscopy

Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University

View on ClinicalTrials.gov

Summary

This randomized, double-blind controlled trial investigates the effectiveness and potential trade-offs of preoperative ultrasound-guided popliteal sciatic and saphenous nerve blocks in patients undergoing ankle arthroscopy, a procedure often performed in day-case settings but associated with significant early postoperative pain and frequent opioid use. The study evaluates whether these nerve blocks can reduce early postoperative pain-measured by the highest NRS score within 24 hours-and examines their impact on functional recovery, including motor strength and ambulation. All patients receive standardized general anesthesia and multimodal analgesia, with outcomes including opioid consumption, ankle weakness, patient satisfaction, range of motion, muscle strength, hospital stay duration, and analgesia-related costs.

Interventions

PROCEDURE

Ultrasound-guided popliteal sciatic and saphenous nerve block

Ultrasound-guided sciatic (20 mL) and saphenous (10 mL) nerve blocks using 0.25% ropivacaine were administered in the prone position before induction. Block success was confirmed via ultrasound (circumferential spread) and sensory loss in relevant ankle dermatomes.

PROCEDURE

Placebo nerve block

The control group underwent the same procedure, with an equivalent volume of 0.9% normal saline injected instead of local anesthetic.
