Brief Summary

Patellar instability (recurrent patellar dislocation) can occur at any age. It is most often seen in young subjects, especially among adolescents. It is commonly accompanied by anatomical factors. A new factor not described in bibliographic sources and characterized by an external torsion of the tibial tuberosity is frequently found in patients with patellar instability thanks to MRIs. This does not seem to be the case when there is no patellar pathology. A statistical study is needed to assess this rotary anomaly. Validate the predictive benefits when measuring the torsion of tibial tuberosity in cases with recurrent patellar dislocation.

Secondary Outcomes (2)

• Measure of Patellar Tilt

  4 reviewers Assessment of 92 IRM of patients. Study data collection from April 2010 until december 2016. Patient duration follow up not applicable. Unit in degre
