Effects of Continuous Lumbar Plexus Nerve Block on Functional Restoration and Outcome After Unilateral Total Knee Arthroplasty
Early physical therapy after knee surgery is very painful on top of pain from surgery. Pain
following surgery can limit recovery. One way to treat pain is by giving intravenous (IV)
pain medication with morphine. Another method is to use a “nerve block” which involves
placing a thin catheter (tube) into the lower back near the nerves that sense pain in the
knee and give a local anesthetic to numb the nerves. Sometimes both methods are used
together. This research is being done to determine whether nerve blocks with a local
anesthetic improve knee recovery in addition to providing pain relief as compared to IV pain
medicine alone
