Design outcomes

Primary

Measure	Time frame
Reduction of pain: The aim is to demonstrate the superiority of the periacetabular pelvic osteotomy (PAO) after Ganz compared to the surgery after Tönnies with reduction of the pain on the VAS scale by the value of 1. For this purpose, the patients are written to, they receive the patient information and are asked to fill out the enclosed questionnaires. The patient fills out the VAS scale in comparison "before surgery" and "now".	—

Secondary

Measure	Time frame
The secondary Outcome is improved functionality, which should be demonstrated by the following clinical scores: Harris Hip Score, HOOS Score, UCLA Activity Score For this purpose, the patients are written to, they receive the patient information and are asked to fill out the enclosed questionnaires. The patient is asked to complete the Harris Hip Score, HOOS Score, and UCLA Activity Score for their pre-surgery condition and at the current time.	—
