找尋股骨植入物最佳擺放位置 Easy Steps to Optimal Femur Alignment
雖然全人工膝關節置換術存活率相當高，多數研究也顯示10年存活率高達95%1，近年研究卻顯示病患滿意度逐漸下降。高達20%患者在術後一年評估表示不滿意2，最近一份研究也顯示10-34%患者在置換後的3個月至5年中有顯著疼痛感3。雖然已有許多研究指出患者相關因素(如年齡、術前OKS和EQ5D、合併症、健康及心理因素)是影響手術結果最大關鍵，手術相關因素(植入物品牌、醫院類型及植入物擺放位置)其實也扮演著重要的角色4。
據研究顯示造成全人工膝關節置換術重建有7%原因是植入物排列不良所導致5，進而導致植入物存活率降低6和不良的病患術後結果報告4。
