“…Similar deterioration of the spatial-temporal parameters and abnormal muscular activation have also been noted more recently [12]. Despite the improved AOFAS scores and function, only 6 months after surgery [13,14], and some restoration of the main gait parameters [15,16], current total ankle arthroplasty does not seem able to re-establish normal joint function fully.…”

“…The only study on energy expenditure after TAA we are aware of is the study by Detrembleur and Leemrijse (2009). In a prospective study, they found an increase in walking speed and a decrease in external mechanical work and energy expenditure at an average of 7 months after TAA surgery.…”

The aim of this study was to investigate whether impaired ankle function after total ankle arthroplasty (TAA) affects the mechanical work during step-to-step transition and the metabolic cost of walking. Respiratory and force plate data were recorded in 11 patients and 11 healthy controls while they walked barefoot at a fixed walking speed (FWS, 1.25 m/s) and at their self-selected speed (SWS). At FWS metabolic cost of transport was 28% higher for the TAA group, but at SWS there was no significant increase. During the stepto-step transition, positive mechanical work generated by the trailing TAA leg was lower and negative mechanical work in the leading intact leg was larger. Despite the increase in mechanical work dissipation during double support, no significant differences in total mechanical work were found over a complete stride. This might be a result of methodological limitations of calculating mechanical work. Nevertheless, mechanical work dissipated during the step-to-step transition at FWS correlated significantly with metabolic cost of transport: r = .540. It was concluded that patients after successful TAA still experienced an impaired lower leg function, which contributed to an increase in mechanical energy dissipation during the step-to-step transition, and to an increase in the metabolic demand of walking.

“…Abnormal early activation of gastrocnemius and peroneus longus at initial contact, was found on electromyography. Finally, a recent paper [13] has claimed that TAR has a beneficial effect on locomotor function, assessed by gait analysis and energy consumption variables.…”
