Analysis of the Ligamentization Process in the Anatomical Ligamentoplasty of the Lateral Ankle Plane to the Hamstrings
Sponsor: Assistance Publique - Hôpitaux de Paris
Summary
This is a prospective bi-centric study, which evaluate the evolution of RMI signal of transplant till 12 months after ligament plasty surgery. As the primary objective, the study aims to define the post-operative timeframe needed to obtain an optimal quality of repair, especially in their restarting of sportive activities, by analysis of RMI signal and biomechanic features modifications. As secondary objectives, the study aims to: * study the correlation between the RMI signal of plasty and the Young's modulus; * study the evolution of RMI of plasty at M3, M6 and M12; * study the evolution of Young's modulus at M3, M6 and M12; * evaluate the reproductibility between 2 lector of RMI measurements; * evaluate the reproductibility between 2 lector of elastography measurements of LTFA; * evaluate the optimal delay of return to sport after ligament plasty surgery of ankle; * develope a score of type SNQ for ankle ligament plasty surgery; * evolution of AOFAS and EVA scores.
