Impact of foot modeling on the quantification of the effect of total ankle replacement: A pilot study

Kinematic and kinetic foot models showed that computing ankle joint angles, moments power with a one-segment modeling approach alters kinematics tends to overestimate power. Nevertheless, gait studies continue implement assess the effect of total replacement. The objective this pilot study was investigate (one-segment versus multi-segment) on how replacement is estimated benefit or degrade patient’s biomechanical performance. Ten subjects post-traumatic osteoarthritis scheduled for 10 asymptomatic were recruited. A multi-segment model used calculate intrinsic joints kinetics during gait. linear mixed kinematic analysis Differences in range motion due significant all subphases interest except midstance. Peak generation significantly overestimated when computed model. Ankle shank-calcaneus dorsi-/plantarflexion did not increase post-operatively loading response phase. ‘group’ found stance pre-swing phase motion, patients showing lower values than controls dorsi/plantarflexion. outcome ‘foot model’ had estimates generation. findings our therefore emphasize clinical assessing therapeutic intervention.
