Impact (means, 95% confidence intervals) of knee pain on the WOMAC pain and function scores in patients with hip OA. The existence of knee pain, in addition to hip OA has a significant effect on the self-reported pain (t test for equality of means, P=.004) and physical function (t test for equality of means, P=.012).
