Combined Rotational Alignment Change after Total Knee Arthroplasty in Different Tibial Component Designs: Implications for Optimal Tibial Component Rotational Alignment
Purpose The rotational alignment of the femoral and tibial components is closely related to the results after total knee arthroplasty (TKA). In this study, we measured the combined rotational alignment change (ΔCR) after TKA and compared the different influence of symmetric and asymmetric tibial component designs on the combined rotational alignment. Materials and Methods Eighty-four patients...
متن کاملAnterior tibial curved cortex is a reliable landmark for tibial rotational alignment in total knee arthroplasty
BACKGROUND Rotational alignment of the tibial component is important for long-term success of total knee arthroplasty (TKA). This study aimed to compare five axes in normal and osteoarthritic (OA) knees to determine a reliable landmark for tibial rotational alignment in TKA. METHODS One hundred twenty patients with OA knees and 40 with normal knees were included. The angle between a line perp...
متن کاملIs There a Gold Standard for Rotational Alignment of the Tibial Component During
INTRODUCTION A successful total knee arthroplasty (TKA) is dependent on many factors, but component alignment is particularly critical. Aligning the femoral component parallel to the transepicondylar axis is generally regarded as the optimal rotational position, since it has been shown to produce a balanced joint, optimize patellar tracking, and minimize patellofemoral shear forces [1,2] the fe...
متن کاملDetermining the rotational alignment of the tibial component at total knee replacement: a comparison of two techniques.
We prospectively assessed the benefits of using either a range-of-movement technique or an anatomical landmark method to determine the rotational alignment of the tibial component during total knee replacement. We analysed the cut proximal tibia intraoperatively, determining anteroposterior axes by the range-of-movement technique and comparing them with the anatomical anteroposterior axis. We f...
متن کاملRelationship between Tibial Baseplate Design and Rotational Alignment Landmarks in Primary Total Knee Arthroplasty
This study evaluated the influence of modern tibial baseplate designs when using the anterior tibial cortex as a primary rotational landmark for the tibial baseplate in TKA. Eighty patients undergoing TKA were randomized in two groups. Group 1 included 25 females and 15 males receiving a posterior-stabilized (PS) symmetric tibial baseplate while Group 2 included 24 females and 16 males receivin...
