The goal of this clinical trial is to compare at 5 years the sporting activity of patients whose ankle had been treated by reconstruction or repair following chronic lateral instability. The main question it aims to answer is:
What is the long-term sporting activity status of patients whose ankle had been treated by reconstruction or repair following chronic lateral instability ?
Participants will visit the clinic once every year during 5 years for clinical checkup.
Patient, male or female, aged ≥ 18 years
A history of trauma including a severe ankle sprain.
Clinical symptoms persisting for at least 3 months at the time of inclusion: pain, swelling, sensation of 'giving way', sensation of instability, recurrent sprains; Clinical tests (drawer test, varus provocation test) confirming grade III laxity; Imaging results (MRI) confirming clinically suspected ligament damage.
Patient affiliated to or benefiting from a social security scheme
Patient with deltoid ligament injury, severe fracture or open trauma
Patient with insufficient ligament remnant and/or in too poor a condition to allow Broström-type repair.
Patient with a symptomatic osteochondral lesion
Patient with ankle hyperlaxity (Beighton score > 3)
Parallel
Anatomical reconstruction
Procedure/SurgeryAnatomical ligamentoplasty or anatomical reconstruction is performed under arthroscopy. The principle of this method, which lasts around 40 minutes under spinal anaesthetic or general anaesthetic, is to reconstruct the LTFA and sometimes also the LCF, if it has been damaged, using a fragment of the tendon gracilis, located in the thigh, removed through an incision under the knee
Broström anatomical repair
Procedure/SurgeryBroström's anatomical repair is performed under arthroscopy. The principle of this method is to tighten and reattach the LTFA using very small anchors, when it is detached from the fibula but not too retracted and still of good quality. If necessary, this may also be accompanied by ligament reinforcement ('gould'), using a fragment of a fibrous structure in the ankle, the extensor retinaculum
Sporting activity
Patients' sporting activity will be assessed using the "Sport" subscale of the Quick FAAM (Foot and Ankle Ability Measure) questionnaire. Minimum value is 0 and maximum value is 32. 32 means a better outcome.
