Title: (EN) Systems and methods for providing deeper knee flexion capabilities for knee prosthesis patients
(ZH) 用于为膝假体患者提供更深膝屈曲能力的系统和方法
Abstract: front page image
(EN) Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing and improved patellar tracking for knee prosthesis patients. Such systems and methods include (i) adding more articular surface to the antero-proximal posterior condyles of a femoral component, including methods to achieve that result, (ii) modifications to the internal geometry of the femoral component and the associated femoral bone cuts with methods of implantation, (iii) asymmetrical tibial components that have an unique articular surface that allows for deeper knee flexion than has previously been available and (iv) asymmetrical femoral condyles that result in more physiologic loading of the joint and improved patellar tracking.
(ZH)

用于为膝假体患者提供更深膝屈曲能力、更大的生理学载荷支撑和改进的髌骨循轨的系统和方法。这样的系统和方法包括:(i)为股骨部件的前近后骨节添加更多的关节表面,包括实现此结果的方法,(ii)对于股骨部件的内几何形状的修改以及使用植入方法对相关股骨切割部的修改,(iii)具有允许比现有情况更深的膝屈曲的独特关节表面的非对称胫骨部件,和(iv)导致更大的生理学关节载荷和改进的髌骨循轨的非对称股骨节。
