In the context of rising numbers in primary total knee arthroplasty, alternative insert designs are being established, which are supposed to show superior results in terms of knee joint kinematics, clinical results and long-term survival in comparison to the traditional cruciate retaining or posterior stabilized insert designs.
The medial pivot design presents equivalent results to the cruciate retaining design with presumed superiority combined with kinematic alignment.
Current data for the dual pivot design is still very limited. A benefit in comparison to traditional insert designs has not yet been demonstrated.
Forthe ultracongruent design, similar clinical results and revision rates as for the posterior stabilized design have been shown so far, but a superiority in this respect cannot be indicated.
The bicruciate retaining design does not present as a meaningful alternative to the traditional insert designs due to a more challenging surgical technique and significantly increased revision rates based on aseptic partial loosening.
在初次全膝关节置换数量不断增加的背景下，正在确立替代的假体设计，与传统的保留交叉韧带或后稳定型假体设计相比，这些设计在膝关节运动学、临床结果和长期生存率方面应显示出更优的结果。
内侧旋转平台设计与保留交叉韧带设计的结果相当，推测其在运动学对线方面具有优势。
双旋转平台设计的现有数据仍然非常有限。与传统假体设计相比的优势尚未得到证实。
到目前为止，超匹配型设计显示出与后稳定型设计相似的临床结果和翻修率，但在这方面不能表明其具有优越性。
双交叉韧带保留型设计并不是传统假体设计的一个有意义的替代方案，因为其手术技术更具挑战性，且由于无菌性部分松动导致翻修率显著增加。
