Pain Management After TKA: Comparison of Short- and Long-term Nerve Blocks

• Status: Completed
• Trial end date: 2019-05-20
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine if there is any significant difference between using a short-term ON-Q nerve block (which is applied prior to surgery and maintained in place until the medication in the initial balls have been fully used, usually 2-4 days) in comparison to a long-term ON-Q nerve block (which is applied prior to surgery and maintained in place up to seven days after surgery). This study will analyze patient reported levels of pain, range of motion, and narcotic use, as well as investigate whether blood loss, blood thinners, and hemoglobin/hematocrit blood levels influence patient pain levels.

This study will compare patient-reported pain, range of motion and narcotic use in total knee arthroplasty patients who receive the short-term and long-term combination nerve block (saphenous and posterior of the adductor canal and wide-field posterior knee.
