Abstract

Backgrounds: Osteoarthritis (OA)is a prevalent disorder characterized by focal loss of articular cartilage in weight-bearing synovial 
joints and associated with significant pain and functional impairment. Sleep disturbances are common symptoms in adults and are 
related to numerous chronic conditions like osteoarthritis.
Aim of the study: To discover the relationship between knee osteoarthritis with sleep disturbances 
Materials and methods: Cross-sectional study, including 102 with knee osteoarthritis consulted outpatient clinic in Al-Sader 
Teaching Hospital / in Al-Basrah during the period from September 2023 to December 2023 assessed for the presence of sleep 
disturbance. Knee osteoarthritis pain was assessed by the VAS scale and the radiological grade of OA was recorded. A sleep scale 
from the Medical Outcome Study (MOS) was used to assess sleep disturbances in patients with knee osteoarthritis over the past 4 
weeks.
Results: Out of the 102 patients with knee osteoarthritis, 73.5 % were female and 72.5% of them were married. The mean age was 
(53.9 ± 11.4) years and the majority 73.5% of the participants were homemakers. Most of the participants had high BMI values 
(31.05 ± 5.7) kg/m2 with increased waist circumference (103.4 ±14.9) cm. About 75% of participants were in grade 2 and 3 
osteoarthritis and about 94% of the patients complained of moderate to severe pain when assessed using Visual Analog Score 
Analysis (VAS). There is a significant association between knee osteoarthritis grades and the MOS sleep scale on one hand and pain 
score assessed by the visual analogue scale on the other hand. Conclusion Sleep disturbances become more prevalent with an increase 
in the grades of knee osteoarthritis and are associated with worse pain scores.
