Abstract
Background: Knee osteoarthritis affects daily activities and quality of life. Treatment options include both non-surgical management and total knee replacement surgery. Comparing the quality of life outcomes between these two approaches will provide useful insights for patient management. This study aim to compare the quality of life of knee osteoarthritis patients undergoing non-surgical treatment versus surgical treatment.
Design: A cross-sectional descriptive study
Methods: Patients with knee osteoarthritis attending the orthopedic clinic were interviewed using the Thai version of the EQ-5D and the Thai version of the Modified WOMAC Scale. Data were analyzed using descriptive statistics and comparative statistical methods, including the Chi-Square test and T-test.
Results: The study included a total of 162 knee osteoarthritis cases, with an average patient age of 70.35 ± 7.4 years. Of these, 72.22% did not undergo surgery. When comparing quality of life using the Thai version of EQ-5D, the surgical group had a better quality of life, as indicated by the overall health assessment score (EQ-VAS) (non-surgical group: 61.1 ± 24.3 vs. surgical group: 72 ± 23.7, p = 0.011). Regarding the Thai version of the Modified WOMAC Scale, the surgical group had significantly lower pain levels (non-surgical group: 17.38 ± 12.32 vs. surgical group: 10.13 ± 13.47, p = 0.001). The most significant differences in pain were observed during stair climbing and walking. Additionally, the surgical group demonstrated better joint functionality.
Conclusion: Total knee replacement surgery improves the quality of life of patients compared to the non-surgical group by significantly reducing pain and enhancing daily functional abilities. These findings provide valuable information for healthcare professionals and patients in selecting the most appropriate treatment approach.
