Brief 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.

Detailed description

The eligible patients will be enrolled in the department of orthopaedic surgery of Ambroise Paré hospital, each patient will undergo a 12-months follow-up in the department of orthopaedic surgery in Armand Trousseau hospital for the elastography evaluations.

Interventions

PROCEDURELigament plastic surgery

Ligament plastic surgery of ankle under arthroscopy for recurrent instable ankle reason and failure of medical treatment.

DIAGNOSTIC_TESTRMI and ultrasound

RMI examination at 3 months on operated ankle, and 3 CT scan examinations with elastography module will be performed at planned timeframes.

Design outcomes

Primary

MeasureTime frameDescription
Classification of RMI signalAt 3 monthsThe classification of RMI signal will be defined as: * frank hyposignal: stage 1; * intermediary signal (close to muscles of T2): stage 2; * moderate hypersignal (close to cartilage of T2): stage 3; * intensive hypersignal (close tointra-articular liquid of T2): stage 4.

Secondary

MeasureTime frameDescription
Anterior talofibular ligament measurementAt 3, 6 and 12 monthsanterior talofibular ligament measurement will be performed by RMI
Calcaneofibular ligament measurementAt 3, 6 and 12 monthscalcaneofibular ligament measurement will be performed by RMI
ElastographyAt 3, 6 and 12 monthsElastography measurements: Young's Modulu
Pain evaluationAt baseline and 3, 6 and 12 monthsBy the American Orthopedic Foot and Ankle Score (AOFAS) to evaluate the pain.
