Taking Part
This website explains the Op NON-STOP study for people who might be interested in joining.

We are recruiting children aged between 5 and 12 years old with newly diagnosed Perthes’ Disease
If you are considering taking part, please follow the link below for more information about what will happen if you decide to take part:
What to Expect
For those who agree to take part, the only way to compare the treatments fairly is to create two groups of children who are the same.
You can’t choose the treatment, and neither can the doctors, otherwise the groups would not be equal. When we have groups of patients who are as identical as possible, we can then compare them fairly in terms of outcomes.
-
Active Containment
Physiotherapy, activity restriction, education and pain relief.
-
Surgical Containment
Surgery to reorient the ball and socket of the hip.
During the research study, we will have brief contact with you by text message and/or email. We will ask questions about pain, activities, how your child feels, hospital attendances, school attendance and costs that you may have incurred in relation to this hip problem (i.e. days absent from work etc.).
