The longevity of total knee prostheses depends mostly on the correct alignment (frontal, sagittal and axial) of the prosthetic components, soft tissue balancing and restoring the mechanical axis of the lower limb.The use of computer-assisted navigation allows more accurate and reproducible restoration of mechanical axis and component positioning, better results in patients with extra-articular deformities and it has an important role in surgical training.Better alignment should lead to an improved functional outcome and an increased long-term survival of the prosthesis. Several studies have proven an improved function in the short and mid-term but we still lack long-term data regarding functional outcome and longevity of the prostheses.
全膝关节假体的使用寿命主要取决于假体组件的正确对线（冠状面、矢状面和轴向）、软组织平衡以及恢复下肢的机械轴。计算机辅助导航的应用可实现更精确且可重复的机械轴恢复和组件定位，对于关节外畸形患者能取得更好的效果，并且在手术训练中具有重要作用。更好的对线应能带来功能结局的改善以及假体长期生存率的提高。多项研究已证实短期内和中期功能有所改善，但我们仍缺乏关于假体功能结局和使用寿命的长期数据。
