Comparing Femoral Nerve Catheters to Single Shot Femoral Nerve Blocks for Total Knee Replacement Surgery

• Status: Completed
• Trial end date: 2015-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to compare two methods of pain control used during total knee joint replacement surgery. The pain medication that will be used for this study is not experimental.

The investigators will compare the single shot femoral nerve block (SSFNB) and Femoral Nerve Block (FNB) plus continuous femoral nerve catheter (CFNC) to determine which method gives patients better pain control, increasing the capability to participate in physical therapy and decreasing the consumption of other pain medication. With either the single shot or the catheter the local numbing medication called ropivacaine will be used.
