Objectives. To evaluate the comparative analgesia effectiveness and safety of postoperative continuous femoral nerve block (CFNB) with patient controlled intravenous analgesia (PCIA) and their impact on knee function and chronic postoperative pain.Methods. Participants were randomly allocated to receive postoperative continuous femoral nerve block (group CFNB) or intravenous patient controlled analgesia (group PCIA). Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores for knee and incidence of chronic postoperative pain at 3, 6, and 12 months postoperatively were compared. postoperative pain and salvage medication at rest or during mobilization 24 hours, 48 hours, and 7 days postoperatively were also recorded.Results. After discharge from the hospital and rehabilitation of joint function, patients in group CFNB reported significantly improved knee flexion and less incidence of chronic postoperative pain at 3 months and 6 months postoperatively (P<0.05). Analgesic rescue medications were significantly reduced in patients receiving CFNB (P<0.001andP=0.031, resp.).Conclusion. With standardized rehabilitation therapy, continuous femoral nerve block analgesia reduced the incidence of chronic postoperative pain, improved motility of replaced joints, and reduced the dosages of rescue analgesic medications, suggesting a recovery-enhancing effect of peripheral nerve block analgesia.

Background: The use of epidural analgesia in the management of postoperative pain following orthopedic surgeries has evolved as a critical component of a multimodal approach to achieve the goal of pain relief, early mobilization, and improved compliance with physiotherapy resulting in overall improved outcomes. Aim: The aim of this study is to compare continuous femoral nerve block with continuous epidural block technique for postoperative analgesia in patients undergoing elective total knee replacement surgery.Subjects and Methods:The patients belonging to the ASA I to III scheduled for various knee surgeries under spinal anesthesia were enrolled in this study. They were randomly divided into two equal groups of thirty-three patients each. The Group F patients received continuous femoral nerve blockade and in the Group E patients continuous epidural blocked preoperatively.Results:The analgesic efficacy of both continuous femoral nerve block and continuous epidural nerve block was equal as measured by the visual analogue scores. The incidence of Hypotension was more in the Epidural group. The adverse effects due to the Continuous Femoral Nerve block were lower in comparison with the Continuous Epidural block technique.Conclusion:Continuous femoral nerve blockade provides postoperative analgesia equivalent to that obtained with a continuous epidural blocked but with lesser side effects.
