摘要

目前探討後方穩定型人工膝關節於高彎曲時其Cam-Post接觸情形的文獻相當缺乏。因此本研究目的，期望能建立一套電腦模擬平台，進而以了解Cam-Post於高彎曲時其接觸的情形。
本研究是利用X光斷層掃描影像重建其骨頭模型再用繪圖軟體(SolidWorks)繪製出後方穩定型之人工膝關節。本模型是以彈簧代替韌帶的方式，運用動態模擬軟體(COSMOS Motion)來模擬高度彎曲的運動情形。
本研究之完成，可以達成下列兩個目標：(1)確切的模擬人工膝關節的高彎曲運動行為；(2)預測Cam與Post之間的接觸情形。

As the high flexion research of the knee has become a new studying interest, the understanding for dynamic contact force for the posterior-stabilized type total knee replacement in a high flexion angle is still lacking. The objective of this study is to create a model to simulate and the dynamic contact force for the posterior-stabilized type total knee replacement in a high flexion angle.
The artificial knee model is constructed by the computed tomography (CT) image of human knee joints using the SolidWorks software. The motion of the knee joints were simulated using the spring instead of the ligament models.
The methodology will contribute to an effective modeling for the knee joint in extreme flexions and predict the distribution of contact force between Cam and Post.
