New treatment option for Ankle Ligament Injury，Chronic Ankle Instability，Ankle Arthroscopy
Official title Preop US-Guided Nerve Blocks for Pain & Recovery After Ankle Arthroscopy
ClinicalTrials.gov ID: NCT07470021
What this study is testing
- What it's testing
- 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.
