Background : Tibial rotation in total knee arthroplasty remains controversial. The aim was to investigate which anatomical reference was closer to SEA in 10 tibial markers in Chinese adult. Methods : The study included 122 normal lower extremities. 10 axes were drawn on the axial sections: ...
It has been reported that medially wedged foot orthoses reduce the range of rearfoot pronation during stance [15], [16], [17], the maximum angle of calcaneal eversion, maximum calcaneal eversion moment during stance [18] and the range of internal tibial rotation associated with rearfoot ...
All reference axes were used for external rotation to the line perpendicular to SEA or SEA itself, except for the MPET axis, which was used for internal rotation to the line perpendicular to SEA. The Akagi line was the closest Discussion Tibial rotation in TKA remains controversial. In the ...
Sagittal translation of the fibula, anterior and posterior widths of the distal tibiofibular syndesmosis, tibiofibular clear space (TFCS), and rotation of the fibula were measured.In the neutrally loaded ankle, the fibula was located anteriorly in the tibial incisura in 88% of the subjects....
They show that the reconstructions do not restore normal tibial rotation. Steadman's group in Vail, CO, USA some years ago showed that hamstring reconstructions of the ACL led to a reduced internal-rotation torque. They pointed out that since all downhill skiing is done in internal rotation (...
angle on the hamstrings muscles suggest that mechanoreceptor feedback is important in the planning and execution of motion and processed in such a way as to result in selective muscular excitation restricting ligamentous strain due to anterior drawer, internal tibial rotation, or a combination of ...
The maximum and minimum flexion/extension, maximum internal rotation and tibial lateral translations increased with the increase of speed. The maximum and minimum tibial proximal translations in running were found being greater than walking. A phenomenon between walking and running was observed: both ...
The eversion to tibial internal rotation excursion ratio was significantly lower in the pronator subjects. Correlation analyses revealed significant relationships between a number of rearfoot and knee parameters. Results suggest that increased motion of the rearfoot can lead to excessiv...
This differential motion equates to femoral external rotation (or tibial internal rotation). It is proposed that this axial rotation is driven by the shapes of the articular surfaces, and not the ligaments. The findings have far-reaching implications for arthroplasty and the understanding of ...
CT-matched tibial grafts had lower peak pressures than unmatched grafts. Peak pressures were on average 24.8% (range [18.3%, 29.6%]) greater than in the native glenoids for unmatched allografts, 21.8% ([17.0%, 25.5%]) greater for the matched allografts, and 4.9% ([3.8%, 5.5%]) ...
