简要总结
Assessment of surgical correction of patello-femoral instability by EOS 3D kinematics
详细描述
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.

结局指标
主要结局
Comparison of patella lateral tilt before and after surgery
时间窗: During the presurgery appointment and up to 6 months 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.
次要结局
- Comparison of patella secondary shifts before and after surgery(During the presurgery appointment and up to 6 months after surgery)
- Assessment of functional and life quality changes pre- and post-surgery(During the presurgery appointment and up to 6 months after surgery)
- Comparison of patella secondary rotations before and after surgery(During the presurgery appointment and up to 6 months after surgery)
