Brief Summary
The patients will be randomized into 2 groups, named group A, B. Group A: The patients will receive Ultrasound guided Genicular nerves block combined with Ultrasound guided IPACK block. Group B: The patients will receive Adductor canal block which will be the control group. The Numerical Rating Scale (NRS) will be used to assess pain intensity. Preoperatively, all study subjects will be trained to use NRS pain scores. The spinal block will be performed. In group A, 15 mL of bupivacaine 0.25% with 2.5 g/mL adrenaline at a concentration 1:4,00,000 will be administered immediately following skin closure. GNB will be performed by using the linear ultrasound probe (10-15 MHz) Sono site M-turbo ultrasonography to scan the long bone shaft with up and down movement to recognize the epicondyle of the tibia and femur. The junctions between the epicondyle and the shafts of the femur and tibia are where the genicular arteries are located; these junctions will be defined as the periosteal areas. The superior lateral, superior medial and inferior medial genicular arteries accompany each genicular nerve. After confirmation of the genicular artery by color Doppler, the needle will be introduced using the in-plane approach and presented in the long axis view. The target point of the needle insertion will be the needle tip beside a genicular artery. Then, a 5 mL volume will be administered after gentle aspiration to prevent a faulty intra-arterial injection at 3 target locations: the superior lateral, superior medial and inferior medial genicular nerves. This will be Followed by the procedure for the IPACK block. In group B, A 22 Gauge 80 mm needle will be guided from lateral to medial to this area called the adductor canal using in-plane technique. 20 mL of 0.5% bupivacaine will be injected with peri-arterial spread after negative aspiration under sterile conditions. TKA will be performed by an orthopedic surgeon by placing three-compartment prostheses with a minimally invasive mini-midvastus approach and using hand-mixed cementing techniques.
