Abstract

Research objective: To describe the relationship between ultrasound imaging and some para-clinical characteristics in patients with knee osteoarthritis (KOA) stages 0 - 1 according to Kellgren - Lawrence (K/L). Research subjects and methods: Prospective cross-sectional study on 157 patients diagnosed with KOA stage 0 - I according to K/L at the Rheumatology Department - Military Hospital 103 from September 2023 to April 2024. Result: On ultrasound, cartilage damage accounted for 52.22%, knee joint effusion 89.8%, osteophytes at the medial tibial plateau and lateral tibial plateau accounted for 33.75% and 24.47% respectively, 20.38% of cases had synovial membrane hypertrophy, 26.11% had periarticular tendonitis and 17.83% had Baker's cysts. Regarding the relationship between ultrasound and para-clinical characteristics, the detection rate of osteophytes on ultrasound and X-ray was equivalent. The relationship between the degree of joint effusion on ultrasound and X-ray was not statistically significant. There was no relationship between cartilage damage and disease stage on X-ray as well as between synovitis lesions on ultrasound and inflammatory factors in blood tests (white blood cells, CRP). Conclusion: The detection rate of osteophytes on ultrasound and X-ray was equivalent. Ultrasound can detect other lesions that X-ray and clionical examniation cannot. There was no relationship between the degree of joint effusion on ultrasound and X-ray. There was no relationship between cartilage damage and disease stage on X-ray. There was no relationship between synovial inflammation on ultrasound and inflammatory factors in blood tests. Ultrasound should be used as a screening and diagnostic method for treating patients with KOA.
