Pain Relief Results After Anterior Cruciate Ligament (ACL) Reconstruction
Outcomes After ACL Reconstruction: The Effect of Femoral Nerve Block Analgesia
Study Overview
Status
Conditions
Detailed Description
In this project, we will measure outcomes of anesthesia and pain management for common orthopedic procedures. The influence of nerve block pain management on outcomes after outpatient anterior cruciate ligament (ACL) reconstruction has not been studied, especially the patient's potential to return to societal productivity during the first week after surgery. Therefore, we have designed a randomized clinical trial to study the role of nerve block pain management techniques on patient outcomes during the first week after surgery and on recovery 3-12 weeks after surgery. Our hypothesis is that patients undergoing nerve block analgesia will manifest better self-reported recovery outcomes, physical function outcomes, and objective measures of neuromuscular function.
We will give consenting patients (n=270) undergoing ACL reconstruction conventional spinal anesthesia and will randomize them to receive femoral nerve block analgesia with either a single injection, a continuous infusion for 2 days, or saline placebo. We will use goniometry to test postoperative range of motion in extension to determine whether the quadriceps femoris torque output is impaired. We will compare patient-reported recovery outcomes across treatment groups using three validated health status measures suitable for daily assessment (Verbal Pain Score, SF-8, and the Quality of Recovery [from anesthesia, QoR-40] Score).
We aim to determine the quality of immediate recovery from anesthesia and the extent of reported pain. We will compare the effects of single injection and continuous infusion on femoral nerve analgesia to determine the better dosing strategy for these patients.
