However, there has been a renewed interest in local infiltration analgesia (LIA), partly due to the work in 2008 of Kerr and Kohan,1 who demonstrated superior analgesia after total knee or hip arthroplasty with extended, diluted infiltration of local anesthesia with epinephrine and ketorolac added and repeated injections through intra-articular catheters. The interest in using LIA in knee and hip surgery may be also due to the lack of the simpler regional anesthesia alternatives that exist for other joints. For instance, analgesia after shoulder and upper extremity surgery can be accomplished with a simple, single injection block of the brachial plexus, whereas analgesia for hip and knee joints requires multiple and more technically challenging nerve blocks. Also, while motor weakness is common with nerve blocks, infiltration analgesia typically spares the motor function.
