About

General Aim: to explore the iKA in TKA related to clinical, biomechanical, and functional outcomes.

Full description

First specific aim: to investigate the kinematics during daily functional movements in individuals with the iKA TKA to those with aMA TKA, as well as the healthy control group.

Second specific aim: to investigate kinetics and muscle activation patterns during functional movements in individuals with the iKA aligned TKA to those with aMA TKA, as well as a healthy control group.

Third specific aim: to investigate the impact of the whole body on functional outcomes following iKA and aMA TKA, in comparison to the healthy control group, and to explore the underlying factors contributing to suboptimal outcomes.
