Study Comparing Combined Adductor Canal and IPACK Blocks to Adductor Canal Block Alone for Pain Relief After High Tibial, Distal Femoral, or Tibial Tubercle Osteotomy in Adults

What this Trial Is About

Researchers are evaluating the effects of combining an adductor canal block with an IPACK infiltration versus using an adductor canal block alone on post-operative pain and opioid use in patients undergoing high tibial osteotomy HTO, distal femoral osteotomy DFO, or tibial tubercle osteotomy TTO. This randomized, single-blind, single-center study focuses on improving pain management after these orthopedic surgeries. Participants are randomly assigned to receive either an adductor canal block ACB combined with an IPACK block or an adductor canal block alone. The ACB involves injecting 15 mL of 0.25% Bupivacaine under ultrasound guidance to block the saphenous nerve, while the IPACK block administers 20 mL of 0.25% Bupivacaine into the space between the popliteal artery and the knee capsule. These treatments are given around the time of surgery to assess their impact on post-operative pain and opioid consumption. During the study, researchers will measure opioid use during the first 24 hours after surgery as the primary outcome. Secondary outcomes include pain scores reported by patients at various time points up to six months after surgery, length of stay in the post-anesthesia care unit, and physical function scores related to knee injury and osteoarthritis. Participants will be monitored for safety, pain control, and recovery progress throughout the post-operative period and follow-up visits up to six months after surgery.
