Comparative Evaluation of Ultrasound-guided Adductor Canal Block with Intra-articular Infiltration versus Intra-articular Analgesia alone in Postoperative Pain Management and Early Ambulation after Total Knee Replacement

Ultrasound-guided ACB combined with intra-articular infiltration provides superior pain control, preserves quadriceps strength, reduces analgesic requirements, and promotes earlier ambulation compared to intra-articular infiltration alone in TKR patients.
