Predictive Factors of Good Results After Multiligamentar Knee Reconstruction (MLKR)

Study Overview
=================
Brief Summary
-----------------
Multiligamentar knee injury has consequences on knee function (instability, arthritis, life disagreement). Surgical reconstructions have known recent evolutions. The goal of this study is to evaluate functional and clinical results at one year of those new surgical technics. A clinical and functional follow up will be performed before the surgery, then at 6 months and one year.

Detailed Description
-----------------
Patients will also benefit of a Magnetic Resonance Imaging (MRI) and isokinetic evaluations at one year.

Arms and Interventions

| --- | --- |
| multiligamentar knee reconstruction<br>Any patient who benefits of a multiligamentar knee reconstruction at hospital of Saint-Etienne will be included. Datas collected by medical record. | Other: Datas collected<br>* Datas collected by medical record: medical data (weight, height, smoking status, history) and socio-demographic data (age, occupation, type of injury) information, assessment of knee function before surgery, at 6 months and 1 year after surgery, magnetic resonance imaging (MRI) and radiological imaging at 1 year after surgery, results of the Iso-kinetic Muscle Assessment Test at 1 year after surgery to objectively determine the recovery of muscle function The data collected will be used to perform a statistical analysis to evaluate the factors predicting a good long-term post-surgical evolution<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional score : International Knee Documentation Committee (IKDC) | The International Knee Documentation Committee (IKDC) is a questionnaire that assigns patients an overall functional score. Three categories are examined by the questionnaire: symptoms, sports activity and knee function, on a scale of 0 to 100. | Months : 0, 6 and 12 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional score : Knee Injury and Osteoarthritis Outcome Score (KOOS) | The Knee Injury and Osteoarthritis Outcome Score (KOOS) is used to assess immediate and long-term patient outcomes after knee injury. Five outcomes are assessed by the self-administered KOOS: pain, symptoms, activities of daily living, sport and recreation function, and knee-related quality of life, on a scale of 0 to 100. | Months : 0, 6 and 12 | 
| Visual Analogue Scale (VAS) scale | Analysis of the Visual Analogue Scale (VAS) scale (from 0 to 10, 10 = pain ++) | Months: 0, 6 and 12 | 
| Laxity | Laxity assessed by Magnetic Resonance Imaging (MRI) | Month : 12 | 
| Joint amplitudes | Joint amplitudes assessed by the iso-cinetic test | Months: 0, 6 and 12 | 
| Clinical data | Data collected at inclusion | Month : 0 | 
| Recovery of muscle function | Recovery of muscle function measured by iso kinetic muscle assessment | Month : 12 |
