Pain is the prevailing symptom of knee osteoarthritis. Central sensitisation creates discordance between pain and joint pathology. We previously reported a central pain mechanisms trait derived from 8 discrete characteristics: neuropathic-like pain, fatigue, cognitive-impact, catastrophising, anxiety, sleep disturbance, depression, and pain distribution. We here validate and show that an 8-item questionnaire, Central Aspects of Pain in the Knee (CAP-Knee) is associated both with sensory and affective components of knee pain severity.
