Pain assessment in elderly patients undergoing total knee arthroplasty: integration of the sane scale

Abstract

Objective: This study evaluates the effectiveness of surgical intervention on pain levels and functionality in patients with knee osteoarthritis. Using validated instruments—the Visual Analog Scale (VAS), McGill Pain Questionnaire, and Single Assessment Numeric Evaluation (SANE)the study assessed changes over three time points: preoperative, 24 hours postoperative, and 30 days postoperative. Methods: Data were collected and analyzed using statistical methods, demonstrating significant reductions in pain and improvements in functional perception. Multidisciplinary approaches were also considered. Results: Pain levels decreased progressively, with significant improvements in functionality. The findings align with prior studies highlighting the role of surgical and multidisciplinary interventions. Conclusion: Surgical intervention effectively reduces pain and enhances functionality, improving quality of life in patients with knee osteoarthritis.
