Resumen

Objective: The objective of our research was to describe the recovery behavior of the ankle joint forces and their mechanical factors during gait in subjects with total ankle replacement with unilateral HINTEGRA prosthesis secondary to trauma during the functional phase. Material and methods: Sixteen male subjects, 8 with unilateral HINTEGRA prosthesis secondary to trauma and 8 subjects without HINTEGRA prosthesis underwent gait analysis. The ankle joint forces behavior and its mechanical factors during gait were obtained. A cross correlation analysis was used with a non-paired Mann-Whitney U test (α = 0.05). Results: There was statistical significance with a smaller cross-correlation coefficient in the anteroposterior, mediolateral joint forces and in shear force environment; lesser second compressive peak, posterior peak, first anterior peak, second anterior peak, time of the second vertical peak, plantar flexion moment peak; and a higher first vertical peak time in subjects with HINTEGRA prosthesis. Conclusions: These results suggest that subjects with HINTEGRA prosthesis secondary to trauma have impaired behavior of the ankle joint forces during the functional phase, creating an inefficient damping and propulsion function, this creating a pathomechanic shear environment that predisposes to higher wear of the interface in the functional phase.
