Riassunto

單髁膝關節置換為近代治療單側脛股骨關節疾病的有效手術方式之一。近年來單髁膝關節置換於十年內的存活率通常可達到九成以上。不過術後的存活率往往會因為脛骨元件幾何外形與手術操作等不同因素而有產生差異。導致單髁膝關節置換失敗進而必須施行再置換手術的原因，絕大部分為脛骨元件沉陷、持續性疼痛或是近端脛骨平台骨折所引起。臨床上發現脛骨元件與骨截面上的覆蓋率不佳，或是手術操作不當與骨截面轉角外形導致應變增加及骨質退化是造成術後失敗的主因。因此，本研究將分析國人內/外側近端脛骨平台幾何外形，並與不同單髁膝關節元件置換系統比較其尺寸與特徽；另一方面，希望藉由改良骨截面上轉角幾何外形以降低應變值，並利用有限元素法模擬評估與材料試驗 機進行模型驗證。本研究結果也將提供臨床醫師在針對罹患單側脛股骨關節退化性關節炎的患者進行單髁膝關節置換手術前挑選脛骨元件及手術操作的參考。
