Ultrasound Guided Combined Adductor Canal, Superior Genicular Nerves and Anterior Femoral Cutaneous Nerves Blocks in Comparison With Periarticular Local Anesthesia Infiltration in Primary Total Knee Arthroplasty
Sponsor: SAMEH ELSHERBINI
Summary
Background: Pain management in total knee arthroplasty continues to evolve especially as an early postoperative analgesia is of paramount importance in achieving patient satisfaction and improving clinical outcomes. The goal of achieving an ideal analgesia modality which facilitates early rehabilitation, prevents knee stiffness, reduces hospital stay due to pain, and promotes good functional outcomes continues to be elusive. Multimodal analgesia has been devised to control postoperative pain and reduce opioid consumption including periarticular injection and peripheral nerve blocks. Rationale: Assess the efficacy of a triple block including Adductor canal block, superior lateral, superior medial genicular nerves block and anterior femoral cutaneous nerves block in comparison with Periarticular infiltration for pain management in patients undergoing a total knee arthroplasty. Methods: Prospective Randomized Control Trial

Periarticular Infiltration
A total volume of 60 mL containing bupivacaine, ketorolac, adrenaline, and tranexamic acid will be infiltrated by the surgeon before prosthesis implantation into the posterior capsule, medial and lateral gutters, quadriceps mechanism, patellar tendon, and medial periosteum.
Ultrasound-Guided Triple Block Technique
Patients will receive a mixture of 45 mL of 0.25% bupivacaine and 8 mg dexamethasone. A total of 15 mL will be injected into the adductor canal, 10 mL for the infrapatellar and medial cutaneous nerve blocks, and 10 mL each for the superior medial and superior lateral genicular nerve blocks.
