Abstract

IntroductionThis paper will review three-dimensional 3D motion analysis studies done in my laboratory to present an overview of what we have found.

Materials and methodsWe 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.

ConclusionThis 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.

This review article was presented at the 87th Annual Meeting of the Japanese Orthopaedic Association as an Instructional Lecture.
