Local infiltration anesthesia after total knee arthroplasty

Introduction: Unsatisfactory pain control after total knee arthroplasty needs to find new approaches and multimodal technique. Recently, local infiltration analgesia has become more popular regardless it’s effect has not be fully investigated.The aim of this study was to investigate the role of local infiltrative anesthesia with postoperative wound local anesthetic solution irrigation in postoperative pain management after primary total knee arthroplasty.Materials and methods: 40 patients with III grade gonarthrosis undergoing total knee arthroplasty under spinal anesthesia were randomly assigned in two groups using envelope method. The main group patients (n=20) were treated with intraoperative local peri- and intraarticular infiltration anesthesia (LIA) and local anesthetic solution irrigation of the wound through 16G catheter 4-6 hours after surgery and on the first postoperative day. The control group patients (n=20) didn’t receive any local anesthesia, but multimodal systemic analgesia (MSA) only...
