原发性膝关节骨关节炎

定义

原发性骨关节炎发生于原本完整膝关节，涉及遗传相关、年龄相关或使用相关性退行性变性，伴微观和宏观解剖变化，最终限制一个或多个关节运动。关节变化包括越来越多的软骨损失和骨质转化，如硬化、骨赘形成和囊肿，以及周围软组织结构的潜在炎症变化。 [possible translation]

Primary osteoarthritis occurring in an otherwise intact knee joint, involving genetically related, age-related or use-related degeneration with microscopic and macroscopic anatomical changes, which ultimately limit motion in one or more joints. Changes to the joint include increasing cartilage loss and osseous transformation such as sclerosis, osteophyte formation and cysts as well as potential inflammatory changes in surrounding soft tissue structures.
