We have described the morphology of the tibia and have introduced a new anatomic AP axis for the tibia. Its geometry has long been a problem for all surgeons aspiring to undertake accurate surgery. This part of the study contributes to this field by providing a way for the surgeon to describe the tibial plateau and orient their surgery in a reliable way. We have also described the morphology of the flexion facet of the femoral condyles, confirming the asymmetry between these spherical objects. Currently we are looking at the extension facets of the femoral condyles which have more complicated shapes. As part of this study, the 3D relationship between conventionally described axes and the flexion axes of the femur (spherical axes) was measured in terms of angles and distances.
Knee kinematics has been addressed; however, the relationship between the physiologic patellar tracking and the surface geometry of the patella-femoral joint has not been addressed. The objectives of the current sty are:
- to redefine the tibio-femoral kinematics based on robust and reproducible frames of reference.
- to investigate three-dimensional patellar tracking in relation to trochlea flexion axis and tibio-femoral flexion axis, and various surfaces of the joint.
- to look at the patella not just as a point, but as a free body, and establish the rules governing its excursion on the trochlea in full extension.
