The cause of dissatisfaction following total knee arthroplasty (TKA) remains elusive. Much attention has been focused on static mechanical alignment as a basis for surgical success and optimising outcomes. More recently, research on both normal and osteoarthritic knees, as well as kinematically aligned TKAs, has suggested that other specific and dynamic factors may be more important than a generic target of 0 ± 3º of a neutral axis. Consideration of these other variables is necessary to understand ideal targets and move beyond generic results.
全膝关节置换术（TKA）后患者不满的原因仍不明确。很多注意力都集中在静态机械对线，将其作为手术成功及优化疗效的基础。最近，针对正常膝关节和骨关节炎膝关节以及运动学对线全膝关节置换术的研究表明，其他特定的动态因素可能比中立轴0±3°的通用目标更为重要。考虑这些其他变量对于理解理想目标并超越一般结果是必要的。
