Adductor Canal Block Versus Periarticular Bupivicaine Injection in Total

Status Completed

Clinical Trial Summary

The objective of the study is to compare the efficacy of adductor canal blocks versus periarticular bupivacaine injections for pain management in total knee arthroplasty. This randomized clinical trial will compare outcomes between adductor canal blocks, periarticular bupivacaine injections, and periarticular liposomal bupivacaine injections. Results from this study will help determine the most appropriate perioperative pain management strategy for patients undergoing a total knee arthroplasty.

Clinical Trial Description

Over 600,000 total knee arthroplasties (TKAs) are performed each year in the United States, with expectations for greater than 4 million/year by the year 2030. Since the onset of TKAs in the 1960's, there have been developments that have improved both functionality and patient satisfaction. In the last decade, a focus has been made on multimodal pain management protocols, more rapid functional recovery, reduced length of hospital stay, and minimizing side effects of treatment while maintaining function and durability. The widespread use of regional anesthesia has led to improvements in pain control, more rapid functional recovery, and reduced length of stay. In recent years many surgeons have transitioned from femoral nerve blocks (proximal femoral nerve) to adductor canal blocks (distal femoral nerve) to maintain a sensory block for pain control, while minimizing any motor blockade that is typically seen in proximal femoral nerve blocks, which would hamper rehabilitation, and increase risk of falls. In addition to regional blocks, which are typically performed in the preoperative setting, some surgeons favor an intraoperative periarticular anesthetic injection (PAI), typically with bupivacaine or the long acting form liposomal bupivacaine, either in conjunction with an adductor canal block, or independently. In theory, PAI has the advantage of a comparable sensory nerve block as an adductor canal block, without the disadvantages and risks, which include prolonged quadriceps weakness, fall risk, and neurologic dysfunction.

The purpose of this randomized control trial is to compare the efficacy of adductor canal blocks versus periarticular bupivacaine injections for pain management in total knee arthroplasty. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
