• Status: Completed
• Trial end date: 2018-12-18
• Target enrollment: 0
• Participant gender: All

Summary

One common anesthetic that is performed for total knee replacement surgery is spinal anesthesia with an adductor canal regional block, which involves injecting numbing medication in the thigh region for pain control after surgery. The aim of this study is to determine whether the addition of another regional block called obturator nerve block, which involves injecting numbing medication in the upper thigh region, will improve pain control after surgery while not sacrificing mobility after surgery.
