The Effect of a Prolonged Peripheral Nerve Block on the Level of Pain After a Knee Replacement

Overview

The aim of this study is to examine the effect of a prolonged peripheral nerve block (utilizing continuous adductor canal block) on the level of pain after a knee replacement surgery

Knee replacement surgery is one of the common orthopedic surgeries for the treatment of chronic knee pain. The period after knee replacement surgery is accompanied by moderate to severe pain that affects the patient's ability to quickly return to function. Peripheral nerve blockers and analgesia of different types, administered as part of the anesthesia process, are optimal in controlling pain after surgery. After the surgery, the patients are admitted in the orthopedic inpatient department for 2-3 days on average after surgery for follow-up and early physical therapy necessary to achieve good results and return the patient to full function as soon as possible. The level of pain greatly affects the success rate of the patient's rehabilitation. Thus, since the duration of peripheral nerve block activity does not exceed 8-16 hours on average, it is suggested to treat the patients with a prolonged peripheral nerve block (utilizing continuous adductor canal block) for 24 hours after surgery.
