CHARACTERISTICS OF CHRONIC KNEE PAIN AND ITS ASSOCIATION WITH SOME GERIATRIC SYNDROMES IN ELDERLY KNEE OSTEOARTHRITIS PATIENTS
Main Article Content
Abstract
Objectives: To describe chronic knee pain and explore its association with some geriatric syndromes in elderly primary knee osteoarthritis patients. Subjects and methods: A cross-sectional descriptive study on 199 patients aged ³ 60 years, diagnosed with primary knee osteoarthritis according to the ACR (1991) criteria and treated at the National Geriatric Hospital from October 2021 to August 2022. Information collected includes: Characteristics of chronic knee pain (duration, location, pain intensity according to the VAS scale); quality of life (EQ-VAS scale); geriatric syndromes (depression, daily functioning, history of falls). Results: The prevalence of chronic knee pain was 84.9%. Among 169 patients with knee osteoarthritis with chronic pain, 76 patients (45%) had pain duration of 3 - 6 months, 93 patients (55%) had pain over 6 months. 85.8% of patients had chronic knee pain on both sides. The average pain intensity, according to the VAS scale at rest, when walking and climbing stairs were 3.19 ± 1.85, 5.05 ± 1.99, and 5.7 ± 2.1, respectively. The rate of activities of daily living impairment (ADL) in the group with chronic knee pain was higher than that in the group without chronic knee pain (p = 0.045). No statistically significant association between chronic knee pain and quality of life, risk of depression, IADL, and history of falls in the past 1 year was found. Conclusion: Chronic knee pain is a common symptom in patients with primary knee osteoarthritis, mainly on both sides of the knee. Chronic knee pain increases the risk of impaired activities of daily living (ADL).
