Background:Despite the advent of innovative knee prosthesis design,a consistent first-option knee implant design in total knee arthroplasty(TKA)remained unsettled.This study aimed to compare the clinical effects among...
Background: Tibial polyethylene wear is related late failure in total knee arthroplasty. The cruciate substitute design depending on the campost mechanism to secure the knee cinematics after a posterior stabilized tot...
Post cam mechanism of Posterior Stabilized (PS) knee prostheses is useful to realize intrinsic stability for cases with severe degeneration. However, some retrieval studies report severe failure of the polyethylene ti...
Acknowledgments We would like to thank the subjects for their time and enthusiasm. We also thank our fluoroscopy technologist Qing-Hua Liu.This work was supported by a grant from the National Natural Science Foundation of China (No. 81472139).
Background: Joint line (JL) is a very important factor for total knee arthroplasty (TKA) to restore. The objective of this study was to evaluate the early clinical and kinematic results of TKAs with posterior-sta...
Purpose: To determine the effect of the posterior condylar offset (PCO) on clinical results after total knee arthroplasty (TKA) using a high-flex posterior-stabilized (PS) fixed-bearing prosthesis. Methods: We...
Background:The goal of total knee arthroplasty (TKA) is to restore knee kinematics.Knee prosthesis design plays a very important role in successful restoration.Here,kinematics models of normal and prosthetic knees ...
