Tibial bearing insert replacement
WebbIntroduction. Over the years significant progress has been achieved in the management of open tibial fractures as reflected by the temporal trend of improving outcomes. 1–3 Nonetheless, open tibial fractures continue to remain one of the most challenging injuries to manage in orthopaedic traumatology. This is primarily due to the relative paucity of … Webb16 maj 2024 · In total knee replacement (TKR), the degree of conformity between tibial and femoral articulating surfaces can be described as the ratio of the radius of curvature of the tibial component (R 2) to the radius of curvature of the femoral component (R 1 ): R 2 /R 1. Such an analysis can be done for the sagittal and coronal geometries.
