Knee kinematics is an analysis of motion pattern that is utilized to assess a comparative, biomechanical performance of healthy nonimplanted knees, injured nonimplanted knees, and various prosthetic knee designs. Unfortunately, a consensus between implanted knee kinematics and outcomes has not been reached. One might hypothesize that the kinematic variances between the nonimplanted and implanted knee might play a role in patient dissatisfaction following TKA. There is a wide range of TKA designs available today. With such variety, it is important for surgeons and engineers to understand the various geometries and kinematic profiles of available prostheses. The purpose of this review is to provide readers with the pertinent information related to TKA kinematics.
膝关节运动学分析是一种运动模式分析，用于评估健康未植入膝关节、受伤未植入膝关节和各种人工膝关节设计的比较生物力学性能。不幸的是，植入膝关节运动学和结果之间尚未达成共识。人们可能假设，非植入膝关节和植入膝关节之间的运动学差异可能在 TKA 后患者不满意方面发挥作用。目前有多种 TKA 设计。由于这种多样性，外科医生和工程师了解可用假体的各种几何形状和运动学特征非常重要。本文综述的目的是为读者提供与 TKA 运动学相关的相关信息。
