Abstract

Research on 157 patients with stage 0 - 1 knee osteoarthritis ( KOA) according to Kellgren - Lawrence (K/L) who were examined and treated at the Rheumatology Department - Military Hospital 103 from September 2023 to April 2024 . The results showed no relationship between knee joint effusion on ultrasound with age, BMI, and disease duration. Ultrasound detected joint effusion lesions in 89.8%, significantly higher with p < 0.001 compared to clinical examination at 7%. The effusion group had statistically higher VAS and WOMAC scores than the non-effusion group with p < 0.05. Ultrasound detected articular cartilage damage such as changes in cartilage properties and decreases in cartilage thickness, while clinical examination and X-ray did not. There was no relationship between the degree of cartilage damage on ultrasound with age, VAS and WOMAC with p > 0.05. There was no correlation between the cartilage thickness at the lateral tibial plateau, medial tibial plateau, and intercondylar area on ultrasound and the degree of pain on clinical examination according to the WOMAC scale, however, there was a trend of negativen inverse correlation tendency from descriptive statistics that the thinner the cartilage thickness, the higher the WOMAC score and vice versa. Ultrasound should be introduced as an initial screening method and applied routinely for diagnosis and treatment.
