Background: Cutpoints (CPs) for mild, moderate and severe pain are established and used primarily in cancer pain. In this study, we wanted to determine the optimal CPs for mild, moderate, and severe pain in joint replacement surgery candidates with osteoarthritis (OA) of the hip or knee, and to validate the different CPs.

Stein E Vollset (1997) Patient-related risk factors for early revision of total hip replacements: A population register-based case-control study of 674 revised hips, Acta Orthopaedica Scandinavica, 68:3,[207][208][209][210][211][212][213][214][215]

Patients with OA of the hip reported no change in pain, stiffness or physical function while waiting for joint replacement surgery, whereas patients with OA of the knee deteriorated on the stiffness and total scales of the WOMAC. This suggests a difference in patient selection, referral pattern or disease development between the patient categories.
