About

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.

Full description

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.

Enrollment: 250 patients

Sex: All

Ages: 7 to 17 years old

Volunteers: Accepts Healthy Volunteers
