Insomnia and progression to total joint replacement in hip (41 737) and knee pain (81 958): a prospective UK biobank cohort study

Abstract

Objective Insomnia often co-exists with hip or knee pain and is associated with greater pain severity. However, there is limited evidence on whether insomnia contributes to progression to joint replacement. Using data from the UK Biobank, we tested whether symptoms of insomnia among people with hip or knee pain are associated with undergoing total hip or knee joint replacement surgery.

Using self-reported baseline data, participants were classified as ‘never’, ‘sometimes’ or ‘usually’ having insomnia symptoms (ie, trouble falling asleep or waking in the night). We examined ..
