Abstract

Objective: To describe the characteristics and role of knee ultrasound in patients with primary knee osteoarthritis at Gia Lam General Hospital. Subjects and Methods: A cross-sectional descriptive study conducted on 350 patients with primary knee osteoarthritis at Gia Lam General Hospital. Results and Conclusion: Among the 350 patients, the female-to-male ratio was 3:1, and the majority were over 59 years old (65%), overweight patients accounted for 75%. Clinically, 28% of patients experienced mild pain, 33% had moderate pain, and 28% had severe pain. Ultrasound findings showed that 90% had cartilage damage, 74.6% had osteophytes, 73.1% had joint effusion, with an average synovial fluid thickness of 11.6 ± 2.1 mm. Additionally, 33.7% had Baker's cysts, and 21.7% had synovial membrane hyperplasia. The detection rate of joint effusion on ultrasound was significantly higher than on X-ray, with a 95% confidence level.
