NCT07739108

Overview

NCT ID: NCT07739108
Lead Sponsor: Bursa Yuksek Ihtisas Training and Research HospitalOTHER_GOV
Official Title: Comparing Suprainguinal Fascia Iliaca Block Versus Adductor Canal Block for Postoperative Pain Control Following Total Knee Arthroplasty;A Prospective, Double-Blind Controlled Trial
Brief Summary: This study evaluates the analgesic efficacy and motor-sparing properties of ultrasound-guided Suprainguinal Fascia Iliaca Block (S-FIB) compared with Adductor Canal Block (ACB) in patients undergoing primary total knee arthroplasty (TKA). The main hypothesis is that ACB better preserves quadriceps muscle strength, allowing earlier functional mobilization, while providing comparable (non-inferior) analgesia to S-FIB.
Conditions: Arthroplasty
Knee Osteoarthritis

Ages Eligible for Study: Adult (18-64)Older Adult (65+)
Sexes Eligible for Study: All
Accepts Healthy Volunteers?: No
Eligibility Criteria: Inclusion Criteria:

ASA Physical Status I, II, or III
