Association of physical performance among community dwelling elderly population with and without knee joint osteoarthritis: cross-sectional study

Background: Knee-osteoarthritis (OA) is a degenerative articular cartilage disease, combined with variable and gradually advancing thigh muscle weakness leading to functional impairments. The population worldwide, is ageing and age-related osteoarthritis is the leading cause of disability, radiographically evident in one out of four individuals between 56–84 years’ old. Osteoarthritis is the primary cause of long-term disability and is ranked second among all pathologies that result in reduced physical activity of all joints, the knee is most frequently affected by OA, which leads to the greatest loss in functional performance and incurs the highest social costs as compared to any other type of arthritis or site of OA. Purpose: The purpose of this study is to find the association of physical performance among community dwelling elderly population with and without knee joint osteoarthritis. Subject and Method: 12 subject were selected on the basis of inclusion and exclusion criteria. Subjects were selected by convenient sampling method. They were divided into 2 groups of knee osteoarthritis and without knee osteoarthritis. To evaluate physical performance in elder’s time up and go test was conducted. The time taken to complete the task of TUG is recorded and then analyse. Result: Time taken to complete the time up and go test was analysed and compare between groups of knee osteoarthritis and without knee osteoarthritis by Unpaired t test (pvalue = <0.0001). Age was compared in between group and it came not significant. BMI in participants with knee OA was higher than in participate without knee OA. When KL Grading and TUGT was compared in group A pvalue: <0.0001 extremely significant. As KL grading was higher the time taken to complete TUGT was also more. Conclusion: Participant with knee joint osteoarthritis takes more time to complete the TUGT than participant without knee osteoarthritis. BMI in participant with OA was higher than in participant without OA. Higher KL Grading value also leads to more time to complete TUGT.
