Abstract
Knee OA is one of the most frequent joint disorders in adults around the world. KOA frequency increases with advancing age, and women are more likely to have it than males. It can be divided into primary or secondary depending on the presence or absence of risk factors such as repetitive knee injuries, previous knee surgery, and joint overuse.
The diagnosis of knee OA is based on both clinical and radiological findings. Clinically Knee OA manifests as joint pain, morning stiffness < 30minutes, joint tenderness, limited movement and joint effusion.
The most common imaging modality used to confirm the clinical diagnosis is a plain x-ray, which shows joint space narrowing, osteophytes and sclerosis.
The aim of the work was to estimate the prevalence of comorbidities and assess the health related quality of life in elderly patients with knee osteoarthritis compared with those of a corresponding non-OA population after adjustment for socioeconomic and life-style characteristics
The study included seventy (70) elderly patients of both sexes aged ≥65 years. 40% of the participants had KOA, while non-OA group made 60%.
Diabetes mellitus, hypertension, Dyslipidemia and Kidney disease were more likely to affect KOA group compared to non-OA subjects with statistically significant difference between the two groups.
We found a statistically significant difference of reduced health related quality of life (both physical and mental) in patients with symptomatic knee OA compared to non-OA subjects.
