Comparison between Ultrasound Guided Femoral Nerve Block versus IPACK Block (Interspace between the Popliteal Artery and Capsule of the Posterior Knee) in patients Undergoing Total Knee Replacement on Postoperative Ambulation and Pain .

Total knee replacement (TKR) is a well-known popular surgical procedure for knee diseases, including end-stage knee osteoarthritis that causes severe postoperative pain and prolonged immobility. TKR is associated with significant postoperative pain. The need for effective analgesia without compromising function is a priority.The current study aims to assess the IPACK block concerning postoperative ambulation as a primary outcome and analgesic efficacy as a secondary outcome when compared with femoral nerve block following TKR.
