In brief: Depends
Different local anesthetics last for different periods of time.
Depending on the local anesthetic, it can last from 1 to 18 hours. This also depends on if you receive a regional nerve block and if a catheter (tube) is placed to continuously dose local anesthetic to the nerve. Femoral nerve blocks are commonly used for acl repairs.
