Efficacy of Peripheral Cutaneous Nerve (PCN) on postoperative pain and functional outcome after total knee arthroplasty: a single-blind, randomized controlled clinical trial".

ABSTRACT:

Background

Postoperative pain is an important complication that impedes the functional recovery of the total knee arthroplasty (TKA). A variety of analgesic methods including the popliteal artery and capsule of the posterior knee block (IPACK), local infiltration analgesia (LIA) and peripheral cutaneous nerve (PCN) block have been applied via intraoperative or postoperative local injection for alleviating pain after TKA. The purpose of this study was to compare the analgesic effect and function outcome of two local anesthetic methods for reducing postoperative pain after TKA.

Methods

We demonstrated the effect of these two methods on postoperative pain, need for additional analgesics, functional recovery, and pain-related secreted proteins.
