Three-dimensional motion analysis and its application in total knee arthroplasty: what we know, and what we should

Introduction:
This paper will review three-dimensional (3D) motion analysis studies done in my laboratory to present an overview of what we have found.
Materials And Methods:
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.
Conclusion:
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.

01:24Absolute Motion Analysis- General Plane Motion
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the...

However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...
