April 14, 2014 updated by: Larry Hsu, Northwestern University

Infrapatellar Nerve Block for Post-operative Analgesia for Knee Arthroscopy

The purpose of this study is to determine whether infrapatellar branch of the saphenous nerve blocks are effective in decreasing analgesic use, promoting earlier mobility, and improving long term outcome scores after knee arthroscopy.
