Clinical and Functional Analysis After Total Knee Arthroplasty

Abstract

Osteoarthritis is a major cause of disability worldwide. Objective: To evaluate the effects of Total Knee Arthroplasty of subjects with knee osteoarthritis by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC ). Methods: Prospective, non-randomized study with convenience sampling. We included subjects with knee osteoarthritis with indication for surgical treatment. We used WOMAC to evaluate the level of pain, joint stiffness, physical activity, and quality of life in the preoperative and postoperative phase six months after unilateral surgery. We compared WOMAC to the factors age, gender, Body Mass Index and the type of angular deformity of the knee. Results: In total, we analyzed 58 patients with significant improvements in pain relief, joint stiffness, level of physical activity, and quality of life six months after total knee arthroplasty according to WOMAC. Conclusion: Total knee arthroplasty showed positive effects on the quality of life of patients with knee osteoarthritis. Level of Evidence II, Cohort Study.
