Osteoarthritis (OA) is the most common form of arthritis and a leading cause of disability worldwide, largely due to pain, the primary symptom of the disease. The pain experience in knee OA in particular is well-recognized as typically transitioning from intermittent weight-bearing pain to a more persistent, chronic pain. Methods to validly assess pain in OA studies have been developed to address the complex nature of the pain experience. The etiology of pain in OA is recognized to be multifactorial, with both intra-articular and extra-articular risk factors. Nonetheless, greater insights are needed into pain mechanisms in OA to enable rational mechanism-based management of pain. Consequences of pain related to OA contribute to a substantial socioeconomic burden.
骨关节炎(OA)是最常见的关节炎类型,也是全球范围内导致残疾的主要原因,主要是由于疼痛,这是该疾病的主要症状。特别是膝关节 OA 的疼痛体验被认为通常从间歇性承重疼痛转变为更持久的慢性疼痛。为了解决疼痛体验的复杂性,已经开发出了有效的评估 OA 研究中疼痛的方法。OA 中疼痛的病因被认为是多因素的,包括关节内和关节外的危险因素。尽管如此,仍需要更多地了解 OA 中的疼痛机制,以便对疼痛进行合理的基于机制的管理。与 OA 相关的疼痛后果导致了巨大的社会经济负担。
