Improved Pain Management in Knee Osteoarthritis-related Surgeries

Evaluating the Effectiveness of Continuously Improved Pain Management in Knee Osteoarthritis-related Surgeries

In recent years, pain management coordinated with enhanced recovery after surgery (ERAS) has been widely applied and rapidly developed in orthopedics, showing promising prospects. Since 2016, our hospital has used a series of continuously improved pain management schemes for patients with knee OA who underwent total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), and high tibial osteotomy (HTO). Here, we retrospectively analyze these patients' clinical data to compare the effects of different pain intervention measures during the perioperative period on postoperative pain, functional exercise, hospital stay, and prognosis of the three surgical methods in an attempt to provide a feasible solution for pain management of these patients.

We retrospectively analyzed the clinical data of patients with knee osteoarthritis (OA) who received surgical treatment to provide a feasible solution for perioperative pain management of these patients. The medical records of 714 patients with knee OA who had undergone total knee arthroplasty (n=551), unicompartmental knee arthroplasty (n=92) and high tibial osteotomy (n=71) were retrospectively analyzed and the cases were divided into Groups A, B, and C, according to the continuously optimized pain management. Clinical data including anesthesia grade, surgery time, functional exercise, hospital stay, pain, emotion, complications and prognosis were compared.
