Abstract

Objectives: To describe clinical characteristics, laboratory findings, and chronic pain features in elderly patients with primary knee osteoarthritis. Subjects and methods: A descriptive cross-sectional study on 199 patients ³ 60 years old diagnosed with primary knee osteoarthritis according to the ACR 1991 criteria who were being treated at the National Geriatric Hospital from October 2021 to August 2022. Results: the most common clinical symptom is chronic knee pain (84.9%), crunching joints (39.7%), and signs of wood shavings (38.7%). The proportion of patients with stage I, II, III, and IV on knee X-ray were 22.4%; 48%; 23.4%, and 2.4%, respectively. Knee ultrasound results showed that 38.1% of patients had joint effusion; 46.2% of patients had thickened synovial membrane; 87.4% of patients had bone spurs. 45% of patients have chronic pain duration from 3-6 months, and 56.4% of pain lasts more than 6 months. The total WOMAC score was 31.5 ± 19.9. The average VAS score at rest was: 3.04 ± 1.82; when walking was: 4.85 ± 2.23 and when climbing stairs was: 5.5 ± 2.13. Conclusion: Main clinical symptoms were knee pain, and knee OA stage II-III, with spine-shaped, thickened activity. The rate of chronic knee pain was 84.9%; persists repeatedly for 6 months and affects the patient's daily activities.
