Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patient informed written consent and ethical committee approval of Faculty of Medicine; Ain Shams University will be obtained before patient allocation.

• Study procedures: Supervisors and experts will do all the study procedures.

Patients undergoing unilateral Total knee replacement (TKR) will be randomly assigned into one of the following groups using computer generated codes (15 patients in each group):

Group 1 (ACB - IPACK group): will receive spinal anesthesia and ultrasound-guided Adductor canal nerve block, as well as infiltration of the space between the popliteal artery and the capsule of the posterior knee (IPACK) block.

Group 2 (GNB - IPACK group): will recieve spinal anesthesia and US guided Genicular nerves block and IPACK block.
