. Pain is the most common symptom of knee osteoarthritis. Until recently, this pain was referred to as nociceptive pain. However, the difficulties of pain management in knee osteoarthritis indicate the possible presence of a neuropathic component. The objective of this study was to determine how often neuropathic component is part of chronic pain in knee osteoarthritis. Material and Methods. The study included 417 patients with knee osteoarthritis. The patients were tested using the Neuropathic Pain (Douleur Neuropathique) 4 Questions and a Numeric Pain Rating Scale. Patients were divided into 2 groups. The first group included patients with a Neuropathic Pain 4 Questions score ? 4, and the second group with a score < 4. Results. The majority of patients included in this study were females (301, 72.2%), and most of the patients scored less than 4 in the questionnaire (231, 55.4%). Among the patients with a score ? 4, 144 (77.4%) were female, which is significantly higher compared to the group of patients who scored < 4, 157 (68%) (p = 0.037). There was no statistically significant difference in age between the two groups (p = 0.231). The current pain intensity, average pain, and maximum pain during the last 4 weeks were significantly higher in the group with a score ? 4 (p < 0.001). Conclusion. A significant number of patients with knee osteoarthritis had a neuropathic component of pain. There were significantly more women in the group with score ? 4, and this group also reported significantly higher current, as well as average and maximum pain during last 4 weeks than the other group.
