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

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.
