Mobile-bearing Total Knee Prostheses Reduce Axial Rotational Constraint Torque
INTRODUCTION: The current study compared in-vitro tibiofemoral axial rotational constraint between 2 posterior stabilized mobile-bearing knee prosthesis and their fixed-bearing counterparts. It was demonstrated that both mobile-bearing knees induced significantly less constraint torque compared to their fixed-bearing counterparts. Highly-constrained design of the fixed-bearing knees substantial...
متن کاملAdvantages of Mobile-bearing Total Knee Arthroplasty
Early historical failure of total knee arthroplasty (TKA) was frequently secondary to aseptic loosening, often associated with malalignment, instability, or use of excessively constrained prosthetic components. With the addition of better surgical instrumentation and operative techniques (ligamentous balancing, improved alignment, etc.) and the use of lowerconformity prosthetic devices, looseni...
متن کاملModular, mobile-bearing hinge total knee arthroplasty.
Early reports of hinge total knee arthroplasty showed high rates of complications and implant failure. Third-generation modular, mobile-bearing, hinge knee arthroplasty systems have evolved to decrease the deleterious stresses that contributed to the failures of earlier designs. The combined series of Barrack et al and Jones et al documents midterm results using the S-ROM Hinge Knee System for ...
متن کاملFixed or mobile-bearing total knee arthroplasty
Fixed and mobile-bearing in total knee arthroplasty are still discussed controversially. In this article, biomechanical and clinical aspects in both fixed and mobile-bearing designs were reviewed. In biomechanical aspect, the mobile-bearing design has proved to provide less tibiofemoral contact stresses under tibiofemoral malalignment conditions. It also provides less wear rate in in-vitro simu...
متن کاملEffect of rotational alignment on outcome of total knee arthroplasty
BACKGROUND AND PURPOSE Poor outcomes have been linked to errors in rotational alignment of total knee arthroplasty components. The aims of this study were to determine the correlation between rotational alignment and outcome, to review the success of revision for malrotated total knee arthroplasty, and to determine whether evidence-based guidelines for malrotated total knee arthroplasty can be ...
