Abstract excerpt

OBJECTIVE: Knee osteoarthritis (OA) is a broadly applied diagnosis that may describe multiple subtypes of pain. The purpose of this study was to identify phenotypes of knee OA, using measures from the following pain-related domains: 1) knee OA pathology, 2) psychological distress, and 3) altered pain neurophysiology. METHODS: Data were selected from a total of 3,494 participants at visit 6 of the Osteoarthritis...
