What the trial is, and whether it could suit you

Osteoarthritis (OA) is a degenerative joint disease characterized by structural changes such as cartilage loss and osteophyte formation, leading to functional limitations and disability. Pain in knee OA involves a complex pathophysiological structure including both nociceptive and neuropathic mechanisms. Identifying the neuropathic pain component is clinically significant for improving quality of life and functional recovery. This cross-sectional controlled clinical study aims to determine the prevalence of neuropathic pain in patients with knee OA and evaluate its impact on pain severity and functional status. Patients will be categorized based on the Douleur Neuropathique 4 (DN4) questionnaire and assessed using various pain and functional scales.
