Abstract :
Introduction: Pain after total knee replacement surgery if not taken care of properly may interfere with early mobilization and recovery process. Infiltrating an anesthetic agent in the joint at the end of surgery is gaining popularity nowadays. So we compared the effects of intraarticular ropivacaine infiltration and single shot femoral nerve block for better post operative pain relief.
Materials and Methods: 60 patients aged 50-75years Scheduled for unilateral total knee replacement surgery under spinal anesthesia were divided in 2 groups. Group I received 150 ml ropivacaine 0.2% (2mg/ml) as an intra-articular infiltration in knee and Group F received single shot femoral block with 0.25% ropivacaine 30ml after surgery. Pain intensity was measured on “Visual Analogue Score” at rest and during passive movement of limb. Rescue opioid consumption and weight bearing ability recorded in all patients for 24hrs postoperative.
Results: Group I subjects had low pain score throughout post operative period (till 24 hours) as compared to group F at rest (p>0.05) as well as with passive limb movements (p
