中文摘要：

膝关节间隙作为评价膝关节炎等疾病的主要指标,其距离的准确测量,为病灶的诊断和治疗提供重要依据。利用精确的膝关节三维骨骼模型,通过数值化求解和三维可视化技术,计算出股骨和胫骨的关节界面间隙,在三维空间中呈现出完整的膝关节间隙,自动地测量和显示任意一层的关节界面间隙,直观且形象地表征出膝关节间隙,为膝关节炎等相关疾病的诊断和治疗提供新方法。

英文摘要：

Knee joint space is the main index to evaluate some knee joint diseases, and can provide an important reference for the diagnosis and treatment of these diseases. By numerical so- lution methods and 3D visualization technologies, this paper provides a tool to visualize the knee joint space in 3D and automatically calculate the knee joint space. Based on the precise3D knee joint bone model, this tool can not only show the whole knee joint space, but also display each layer knee joint space, which is valuable to diagnose the knee arthritis or other related diseases.
