Correlation of Knee Injury and Osteoarthritis Outcome Scores with Anthropometric measure and Flexibility in subjects with OA Knee

Abstract

Background of the study: Osteoarthritis knee is the most common joint disease that affects the aged people and result in long term disability. Osteoarthritis knee cause degenerative joint disease, wear and tear changes occurring in old age due to weight bearing and loss of articular cartilage. It occurs in 12.1% population approximately. Increased BMI is a well-recognized risk factor for radiographic knee osteoarthritis however, the contributions from joint mobility also have an impact on subjects with knee osteoarthritis. The objective of the study is to find out the correlation of knee injury and osteoarthritis outcome score (KOOS) with anthropometric measures and flexibility in subjects with Knee OA. Methodology: This is an observational study of analytical type, total of 100 subjects. 47 male and 53 female subjects aged above 55years with pre-diagnosed knee osteoarthitis were included for the study. Subjects with knee pain for last 3 months will be included in this study by convenient sampling method. Visual Analogue scale, knee injury and osteoarthritis outcome score (KOOS) questionnaire were used as an outcome measure, weighing scale, goniometer were the tools used for this study. The study was carried out at old aged home for 3 months. Result: A Positive Association and correlation between Knee ROM and Knee Injury and Osteoarthritis Outcome Score (KOOS) with Pearson value is 0.573 indicates an increase in KOOS score decreases knee range of motion in subjects with knee osteoarthritis. Conclusion: The study concluded that there is significant correlation with Knee injury and osteoarthritis outcome score (KOOS) and anthropometric measures in subjects with knee osteoarthritis.
