Official title
Ultrasound Guided Adductor Canal Block vs Intra-Operative Trans-Articular Saphenous Nerve Block: A Prospective Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators will be comparing the efficacy of two different techniques for performing an adductor canal block to the saphenous nerve as a part of the multimodal pain control regimen for total knee arthroplasty. The investigators will be comparing a "low adductor canal block" in which the surgeon administers local anesthetic to the distal aspect of the nerve from the operative site to a "high adductor canal block" in which the anesthesiologist administers the local anesthetic more proximally along the thigh using ultrasound guidance. The investigators will power the study for non-inferiority to compare the newer "low" block to the more commonly performed and more widely studied "high" block.
