Effect of Lower Extremity Traction on the Popliteal Angle After Percutaneous Needle Tenotomy of the Knee Flexor Muscles.

Study Overview
=================
Brief Summary
-----------------
People with neuromotor disability (i.e. following an inborn or acquired spinal cord, cerebral or peripheral neurological lesion) are at risk of neuro-orthopaedic disorders. Microinvasive percutaneous needle tenotomy is a frequent use alternative to open surgery to treat limb deformities. A lower extremity traction is performed in our unit during 2 to 7 days after surgery of the knee flexor muscles. The aim of this study is to describe the efficiency of lower extremity traction on the popliteal angle after percutaneous needle tenotomy of the knee flexor muscles.

Detailed Description
-----------------
This is a prospective, monocentric, cohort study of neurological disabled inpatients subjects treated in the perioperative disability unit (UPOH) of our university hospital for limb deformities by percutaneous needle tenotomy of the knee flexor muscles. All eligible inpatient subjects with neuromotor disability and admitted for the treatment of limb deformities by percutaneous needle tenotomy of the knee flexor muscles will be consecutively included. Data will be collected from the patients' medical records, in particular data related to their clinical, radiological, biological, and physiological examinations. This is a routine care study; no procedures are added for research purposes. It is an ancillary study to the NO-AGING study.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Popliteal angle at the end of the traction | Difference in popliteal angle between the beginning and end of traction, evaluated with the Kinovea angle measurement tool. In case of bilateral traction, the average of the differences of each limb will be considered. | Daily, during the traction (up to 7 days). | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Success of surgery | Evaluated by the Goal Assessment Scale (GAS). Minimum and maximum values : -2 (worse outcome) / +2 (better outcome) | At 30 days after surgery | 
| Popliteal angle | Evaluated by goniometry or Kinovea | Daily, during the traction (up to 7 days). | 
| Knee angle | Evaluated by goniometry or Kinovea | Daily, during the traction (up to 7 days). | 
| Pain | Numeric scale or Algoplus according to disability. Minimum and maximum values for the Numeric scale : 0 (no pain) / 10 (worst pain). Minimum and maximum values for the Algoplus scale : 0 (no pain) / 5 (worst pain). | Daily, during the traction (up to 7 days). | 
| Skin condition | Presence of erythema, phlyctens or superficial pressure sores | Daily, during the traction (up to 7 days). |
