This paper will review three-dimensional (3D) motion analysis studies done in my laboratory to present an overview of what we have found.
We have looked at parameters such as roll-back, rotation, the pivot center of rotation etc. using a 2D-3D registration technique by evaluating knees before and after implantation of a total knee arthroplasty.
This technique allows comparison of preoperative motion to that after total knee surgery. We have found the phenomenon of "reverse screw-home" to be a common motion pattern in osteoarthritis and it is often present after implantation of a total knee prosthesis.
本文将回顾在我的实验室中进行的三维(3D)运动分析研究,以概述我们的发现。
我们通过评估全膝关节置换术前和术后的膝关节,使用二维-三维配准技术研究了诸如后滚、旋转、旋转枢轴中心等参数。
该技术允许将术前运动与全膝关节置换术后的运动进行比较。我们发现“反向旋入”现象是骨关节炎中一种常见的运动模式,并且在全膝关节假体植入后经常出现。
