Clinical Trial Summary

Study will evaluate the effect of liposomal bupivacaine versus standard bupivacaine on physical therapy measures and pain scores as well as opiate consumption.


Clinical Trial Description

Total knee arthroplasty (TKA) can be associated with a large amount of postoperative pain. This pain can oftentimes be severe enough to limit participation in physical therapy and ultimately delay discharge resulting in increased cost. Several strategies have been developed in an effort to decrease postoperative pain following TKA while maintaining lower extremity strength and maximizing participation in physical therapy. Recently, adductor canal blockade has gained popularity as it is reported to provide analgesia to the anterior knee without resulting in significant quadriceps muscle weakness. One downside of single shot peripheral blockade is the duration of analgesia can oftentimes be short lived. The advent of depot local anesthetics has made this an attractive option, especially in busy practices where placing peri-neural catheters may not be practical or cost effective. This study aims to carefully evaluate this relationship using a physical therapy evaluation method that relies on both motor strength and pain control. In addition, we hope to carefully evaluate motor strength using a novel method of strength measurement in an effort to further evaluate the impact of depot local anesthetic injection into the adductor canal on physical therapy and analgesia.
