Periacetabular Osteotomy with and without Arthroscopy for Hip Dysplasia

This study is looking at whether adding a hip arthroscopy (a minimally invasive surgery using a small camera) at the same time as a Periacetabular Osteotomy (PAO) improves outcomes for people with hip dysplasia. Hip dysplasia is a condition where the hip socket is not formed correctly, which can lead to pain and arthritis. The PAO surgery reorients the hip socket to reduce stress. Sometimes, people with hip dysplasia also have other problems inside the hip joint, like labral tears, which a hip arthroscopy can address. This study will randomly assign participants to receive either a PAO alone or a PAO with a hip arthroscopy. Researchers will measure your hip function using a questionnaire called iHOT-33 after 24 months to see which approach works best. You may be able to join if you are between 16 and 50 years old, have symptomatic hip dysplasia requiring PAO, and have had a pre-operative MRI.

Study design
This study is an interventional trial that will randomly assign participants to one of two treatment groups: PAO with hip arthroscopy or PAO without hip arthroscopy. It plans to enroll 204 participants.

Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 2 years after surgery to assess their hip function.

What this trial measures

  • iHOT-3324 months

    Patient-reported quality of life will be the primary outcome used for comparison between the two treatment groups as measured by the International Hip Outcome Tool (iHOT-33). The iHOT-33 is a validated, self-administered quality of life assessment tool for young, active patients with hip symptoms.
