Adductor Canal Block With Tourniquet for Posterior Knee Pain After Total Knee Arthroplasty

NIH registered a new clinical trial examining whether adding a thigh tourniquet to adductor canal block anesthesia improves posterior knee pain management after total knee replacement surgery. The study compares two intervention groups: Tourniquet-Assisted Adductor Canal Block (T-ACB) versus Standard Adductor Canal Block (S-ACB). This is a Phase 4 randomized trial registered in the ClinicalTrials.gov database.

Healthcare providers and clinical investigators monitoring this trial may be interested in the outcomes for informing regional anesthesia protocols. The trial addresses a documented gap in pain management at the posterior knee, where standard regional anesthesia often provides insufficient coverage for the back of the knee joint.
