Abstract:
Objective To explore the feasibility of constructing three-dimensional model after the unicompartmental knee arthroplasty using the point-to-point image registration technology,so as to provide experimental basis for further application and optimization.Methods Patients of medial compartment knee osteoarthritis undergoing UKA were chosen and their postoperative three-dimensional knee models were established based on the MRI and CT scans.The virtual prosthetic replacement and finite element models were constructed using point-to-point image registration technology,and the kinematic changes were analyzed.Results The complete postoperative three-dimensional knee models of UKA were established,and the kinematic charateristics were similar to those conducted in traditional methods.Conclusion The virtual surgery can be performed using the point-to-point image registration technology,and it is both easier and more convenient than the traditional methods.
