Continuous Femoral Nerve Block Following Total Knee Replacement
Summary
The purpose of this study is to determine if putting local anesthetic-or numbing medication-through a tiny tube next to the nerves that go to the knee will improve pain control during physical therapy, and ultimately improve the results of surgery. It will also determine if patients having knee replacement surgery may receive the same or better pain control at home compared with staying in the hospital, and if this improves their experience following surgery.
