An observational study in Ligament; Laxity and Recurrent Patellar Dislocation, sponsored by Polish Mother Memorial Hospital Research Institute. Completed at 2 sites in Poland.

Sponsored by Polish Mother Memorial Hospital Research Institute · Observational
The purpose of this study is to assess correlation between recurrent patella dislocation and genetic polymorphism rs1800012 of the COL1A1 Gene and rs12722 of the COL5A1 Gene.
After being informed about the study and potential risk all of participants were performed phisical examination and genetic test. In the study we established two groups: In first group- 50 patients with recurrent patellar dislocation and without any genetic disorders. In the second one 200 patients without recurrent patellar dislocation and genetic disorders. All pediatric patients were between 7 and 17 years old in two groups respectivly.
115 studies on the registry are indexed under Joint Instability; 21 are open to participants now.
This study's enrollment of 250 is above the median of 60 across 54 observational studies indexed under Joint Instability.
