Epidural Catheter With or Without Adductor Canal Nerve Block for Postoperative Analgesia Following Total Knee Arthroplasty

• Status: Completed
• Trial end date: 2017-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to further investigate the efficacy of adductor canal nerve blocks for pain management after total knee replacement. Specifically we are studying adductor canal nerve blocks in conjunction with epidural anesthesia, which is a combination that has not been extensively researched before. Our question is whether combining these modalities will enhance patient satisfaction after surgery and accelerate patients' readiness to discharge.
