Management of knee pain.

People who have osteoarthritis (OA) and health care professionals who treat and/or research it have helped to develop a guidebook on OA. The guidebook, which includes both lay experiential and clinical evidence-based knowledge, is intended to be used in the consultation and to provide an ongoing resource for patients. The inclusion of lay experiences means professional advice is set in the everyday world of patients and that health care professionals are made aware of lay priorities and different ways of coping. The guidebook is still in the research phase but will be part of a complex intervention in a forthcoming study.
