Factors associated with knee pain in 5148 women aged 50 years and older: A population-based study.

The presence of depressive symptoms may aggravate knee pain in women with knee osteoarthritis. Attention needs to be focused on concomitant musculoskeletal problems such as lumbar spinal and hip diseases in women with knee pain.
