Pre-existing or chronic pain is an established risk factor for severe post-operative pain. In this prospective observational cohort-study, we investigate whether a history of chronic pain, beyond the presence of hip-related pain, affects other post-operative factors including early mobilization, function, and psychological distress following hip surgery.Patients undergoing total hip replacement surgery were observed from the pre-operative day until the seventh post-operative day. Prior to surgery, they were characterized by their pain history, pain intensity, function and psychological characteristics.
