Abstract
Frequency of neuropathic pain and its impact on functional status in primary knee osteoarthritis patients
Highlights
Osteoarthritis (OA) is the most common form of joint disorder, with knee OA being a leading cause of disability among older adults globally[1]
Knee OA has been considered the archetypal model of inflammatory or nociceptive pain[9], it is increasingly apparent that people with knee OA may present with different pain phenotypes
It is recognized that some individuals with knee OA exhibit features of neuropathic pain[9]
Summary
Osteoarthritis (OA) is the most common form of joint disorder, with knee OA being a leading cause of disability among older adults globally[1]. It causes significant morbidity in elderly individuals, and its age of onset is gradually decreasing[2]. Neuropathic mechanisms are considered to play a role in development of pain in knee osteoarthritis (OA). Pain severity was assessed by Numerical rating scale (NRS), neuropathic pain was assessed by Douleur Neuropathique en 4 (DN4) questionnaire and functional status was assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale. Neuropathic pain is a factor that increases pain and disability and disrupts functional status in osteoarthritis patients.
