Continuous Adductor Canal Block in Outpatient Total Knee Arthroplasty

• Status: Not yet recruiting

• Target enrollment: 0
• Participant gender: All

Summary

Total knee arthroplasty (TKA) is a frequent performed surgery. Many institutions are implementing outpatient programs for this surgery and adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. The purpose of this study is to evaluate effectiveness and safety of using CNB in patients undergoing ambulatory TKA, and its effects on patients' quality of recovery. We hypothesize that continuous adductor canal block would lead to a better quality of recovery in patients undergoing outpatient TKA.
