Exploring the effect of step length and shank angle during split squats with the rear foot on the ground, Schütz et al. (2014) compared step lengths of 55 %, 70 %, and 85 % of leg length and
tibia angles of 60, 75, 90 (tibia perpendicular to the ground) and 105 degrees across both front and rear legs.
«Do foot and
tibia angles affect loading impact rates in runners?.»
This study shows that
tibia angle and step length are important variables to consider during the split squat.
With the exceptions of the one about the 120 - degree femur -
tibia angle, and the slope of the pasterns, they are scientifically insupportable and unnecessary.

To address this, researchers recently studied the relationship between foot
angle (
angle formed between the ground and foot on initial contact with the ground) & tibial
angle (
angle of the
tibia from perpendicular landing) with vertical average load rate as well as vertical instantaneous load rates.
Instead of rotating the bone to flatten the plateau like TPLO, a cut is made on the non-weight bearing front part of the
tibia and the patellar tendon is advanced and plated as a wedge at a new perpendicular
angle.
``... if the femur has achieved its genetically determined normal length at eight months when a dog gets spayed or neutered, but the
tibia, which normally stops growing at 12 to 14 months of age continues to grow, then an abnormal
angle may develop at the stifle.
More radiographs are taken after surgery and new measurements are taken to Model of
tibia after TPLOdetermine the new
angle of the slope at the top of the
tibia.
«We change the
angle of the top of the
tibia (shin bone) by cutting the bone and rotating it so that the other muscles supporting the knee can take over the functions of the CCL.»
Many radiographs are necessary to calculate the
angle of the osteotomy (the cut in the
tibia).
The idea is to change the
angle at which the femur bears weight on the flat «plateau» of the
tibia.
If an x-ray of the knee is taken, it can be seen that there is an
angle formed between the top of the
