OA is the most prevalent disease affecting movable joints, primarily targeting the knee, hip, and hands. Characterized by the progressive erosion of articular cartilage, OA is marked by increasing pain during joint movement and a decreasing ability for the joint to withstand mechanical stress. Over time, this condition restricts joint mobility and impairs its function. However, current OA treatments remain largely symptomatic, providing temporary relief from pain but falling short of preventing cartilage damage and the destruction of other joint tissues. Given this treatment gap, the OA disease model plays a crucial role. This model is a representation of the disease that simulates its pathogenesis, symptoms, and progression. It serves as a valuable tool for researchers to better understand OA's underlying mechanisms, evaluate the efficacy of potential therapeutic agents, and explore new treatment strategies.
