Assessment of surgical correction of patello-femoral instability by EOS 3D kinematics
Patella instability induces repetitive patella dislocation, which impairs day-to-day life. Surgery is commonly used to stabilise the patella during knee flexion. However proofs of efficacy of surgery on patello-femoral kinematics have not yet been found. Analysis of the patello-femoral kinematics is crucial to understand, assess et correct the patella instability. The investigators have developed, validated and published a 3D analysis method from biplanar X-rays (EOS 3D imaging). Our aim in this study is to assess the correction of the patello-femoral kinematics after surgery using the EOS 3D imaging method.

Exclusion Criteria:
Patients with patello-femoral instability will undergo EOS 3D Imaging protocol before and after undergoing corrective surgery
Procedure: EOS 3D imaging protocol pre- and post-surgery
Patients will undergo a EOS 3D Imaging protocol before and 6 months after undergoing patello-femoral surgery. This protocol is already used routinely in the hospital before every patello-femoral surgery.
Comparison of patella lateral tilt before and after surgery
Efficacy of corrective surgery on patello-femoral instability will be assessed by measuring the patella lateral tilt (Ry) with the knee bending at 0, 20 and 45 degrees, before and after surgery. This measurement will be done using the EOS 3D Imaging technique.
Time frame: During the presurgery appointment and up to 6 months after surgery
Comparison of patella secondary shifts before and after surgery
Anterior (Tx), distal (Ty) and lateral (Tz) patella shifts, with the knee bending at 0, 20 and 45 degrees will be measured, before and after surgery. This measurement will be done using the EOS 3D Imaging technique.
Time frame: During the presurgery appointment and up to 6 months after surgery
Comparison of patella secondary rotations before and after surgery
External (Rx) and flexion (Rz) rotation of the patella, with the knee bending at 0, 20 and 45 degrees will be measured, before and after surgery. This measurement will be done using the EOS 3D Imaging technique.
Time frame: During the presurgery appointment and up to 6 months after surgery
Assessment of functional and life quality changes pre- and post-surgery
The Kujala score and 12-Item Short Form Survey (SF12) life quality questionnaire will be answered by the participants before and after the surgery.
Time frame: During the presurgery appointment and up to 6 months after surgery
