Medial pivot total knee arthroplasty implants are designed to function in a similar manner to that of the native knee with a relatively fixed medial center of rotation and a less conforming lateral compartment that follows an arcuate path. Medial pivot implants in total knee arthroplasty have increased in popularity with many companies offering medial pivot or retrofitted medial congruent implants, and there are variations between the various medial pivot and medial congruent implants. Existing literature on medial pivot implants have demonstrated high survivorship and patient outcomes. More studies are needed to compare newer medial pivot implants with each other and with retrofitted medial congruent implants.
内侧旋转铰链式全膝关节假体的设计理念是使其在功能上类似于自然膝关节，即相对固定的内侧旋转中心和顺应性较差的外侧间室，后者遵循弧形轨迹。随着越来越多的公司提供内侧旋转铰链或改良的内侧吻合假体，内侧旋转铰链式全膝关节假体的应用也越来越广泛，各种内侧旋转铰链和内侧吻合假体之间存在差异。现有的内侧旋转铰链式假体文献表明其具有较高的生存率和患者预后。需要更多的研究来比较新型的内侧旋转铰链式假体彼此之间以及与改良的内侧吻合假体之间的差异。
