Because opening wedge medial HTO and HTO with external fixator enable the surgeon to modify the tibial slope, they are the only osteotomies that can be performed in patients with a PCL/PLC-deficient knee, and only these osteotomies are discussed in this section.
[61], the amount of posterior tibial slope after HTO depends on the position of the plate used to stabilize the osteotomy; for example, an anteromedial plate increases the slope on average by 5.5° and a posteromedial plate tends not to modify the posterior tibial slope (Fig. 4).
The epigenome modifies the genome.
In a multiple linear regression model of tibial lead concentrations, the VDR genotype modified the relation between age and tibial lead concentrations; subjects with the B allele had larger increases in tibial lead concentrations with increasing age (0.37, 0.48, and 0.67 microg/g per year of age in subjects with bb, Bb, and BB, respectively; the adjusted p-value for trend in slopes = 0.04).
Levy et al. [9] modified the Synthes® Lateral Tibial Head Buttress Plate for use at the distal humerus.
In contrast, the navigation system allows the surgeon to modify the femoral flexion and tibial slope, according to the patient's original anatomy.
The VDR genotype also modified the relation between years since last exposure to lead and tibial lead concentrations.
Since meniscal tears are associated with structural changes of OA (including cartilage defect scores, reduced tibial cartilage volume, and increased tibial bone area [ 2- 7, 24]), it is possible that modifying the gait parameters examined in this study (for example, via gait retraining or orthoses) may also help to reduce the incidence and burden of knee OA.
Heatley modified the angle of the osteotomy to achieve anteriorisation with minimal medialisation of the tibial tubercle.
To address this problem we first modified the surgical technique and then introduced a new design with a convex domed tibial plateau.
