The impact of OA is not limited to physical symptoms only; several studies have shown that OA has a negative effect on a person’s mental well-being and their health-related quality of life [4, 13]. A recent US study measured the health-related quality of life of patients with OA using a generic quality of well-being scale. The quality of well-being scale score of these patients was 0.64, which was lower than that of the community-matched cohort (0.71) and similar to scores from patients with depression (0.64) or advanced cancer (0.63) [4, 17].
