Verification of phycological factors related to health-related quality of life in elderly knee osteoarthritis: A prospective cohort study.

Abstract

BACKGROUND:

In recent years, locomotive syndrome, which is a condition requiring nursing care due to musculoskeletal disease, has been reported, and interest in knee osteoarthritis has been increasing. Several studies have reported the physical factors influencing the relationship between knee osteoarthritis and health-related quality of life (HRQOL), but there have been no reports verifying the changes over time in the relationship between psychosocial factors and HRQOL. This study aimed to investigate the influence of psychosocial factors on HRQOL in elderly patients with knee osteoarthritis.

METHODS:

Evaluations were conducted at four time points: before exercise therapy intervention, 1 month into intervention, 3 months into intervention, and 1 month after completion of intervention. The items investigated were (1) Japanese Orthopedic Association (JOA) score, (2) Kellgren-Lawrence (K-L) grading system, (3) Fall Efficacy Scale (FES), (4) Frenchay Activities Index (FAI), (5) Geriatric Depression Scale (GDS), and (6) Short Form-8 (SF-8).

RESULTS:

No significant differences were seen between each time point of exercise therapy intervention in depression and HRQOL scale but a significant improvement was seen in instrumental ADL and fear of falling at 3 months into intervention. On multiple regression analysis with SF-8 subscales, fear of falling and degree of depression were determined as significant factors affecting physical and mental summary scores.

CONCLUSION:

Elderly patients with knee osteoarthritis require not only intervention for knee function, but also psychological intervention to address decreased activity and depression to improve their HRQOL.
