Official title

A Comparison of Analgesic Efficacy of Ultrasound-Guided Genicular Nerve Block Versus Saline Injection for Total Knee Replacement: a Prospective, Randomized Controlled Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Do ultrasound-guided genicular nerve blocks with 0.5% bupivacaine provide improved knee analgesia for patients recovering from total knee replacement surgery compared to saline injection? Hypotheses: The investigators hypothesize that the combination of ultrasound-guided adductor canal block (ACB) and genicular nerve block will achieve lower opioid consumption and therefore lead to decreased systemic side effects and improved overall satisfaction compared to ultrasound-guided saline injection for patients undergoing minimally invasive elective total knee arthroplasty (TKA).
