In vivo kinematic measurement of transfibular total ankle arthroplasty and natural ankles using bi-plane fluoroscopy.
Background: We aimed to evaluate the in vivo kinematics of transfibular fixed-bearing total ankle arthroplasty (TAA) and compared them with those of natural ankles.
Methods: Eleven TAA patients and 11 participants with natural ankles performed weightbearing and nonweightbearing dorsi-plantarflexion, deep squats, and kneeling. The activities were recorded using bi-plane fluoroscopy. The joint angles for each activity were estimated utilizing the model-image registration technique.
Results: TAA restored physiological kinematic patterns, with consistent inversion and internal rotation during plantarflexion. However, the range of motion in the TAA group was significantly reduced compared to those of the natural ankles group. In deep squat and kneeling postures, joint angles in the TAA group were only 30-40 % of those in natural ankles.
Conclusion: Despite restoring physiological motion patterns, TAA demonstrated substantial limitations in mobility, emphasizing the need for advancements in surgical techniques and implant design.
期刊介绍：
Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society.
The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
