Radiographic and Navigation Measurements of TKA Limb Alignment Do Not Correlate

Design modifications of high-flexion TKA do not improve short term clinical and radiographic outcomes

BACKGROUND The prosthesis of contemporary total knee arthroplasty (TKA) has been modified to provide a more familiar environment for higher flexion angle of the replaced knee. The design modifications continue based on evidence reported in the literature. However, whether these modifications of the prosthesis design lead to improvements in clinical results needs further investigation. We determ...

Title:design Modifications of High-flexion Tka Do Not Improve Short Term Clinical and Radiographic Outcomes

Novel approach to reducing discrepancies in radiographic and navigational limb alignments in computer-assisted TKA.

This study was conducted (1) to document discrepancies between preoperative and postoperative radiographic measurements and postregistration and postimplantation intraoperative navigational measurements of coronal limb alignments, and (2) to identify predictors of discrepancies between radiographic and navigational measures. In addition, we propose the use of a novel radiographic measuring meth...

Do small changes in rotation affect measurements of lower extremity limb alignment?

BACKGROUND The alignment of the lower extremity has important implications in the development of knee arthritis. The effect of incremental rotations of the limb on common parameters of alignment has not been studied. The purpose of the study was to (1) determine the standardized neutral position measurements of alignment and (2) determine the effect of rotation on commonly used measurements of ...

Bone Cement Solidifiliation Influence the Limb Alignment and Gap Balance during TKA

INTRODUCTION Mechanical alignment deviation after total knee arthroplasty is a major reason for early loosening of the prosthesis. Achieving optimum cement penetration during fixation of the femoral and tibial component is an essential step in performing a successful total knee arthroplasty. Bone cement is used to solidify the bone and prosthesis. Thickness imbalance of bone cement leads to the...
