Hip shape, movement, and recovery after hip-preserving surgery for hip dysplasia
Longitudinal Biomechanics and Patient-Reported Outcomes after Periacetabular Osteotomy for Developmental Dysplasia of the Hip
Looks at how hip shape, movement forces, and patient-reported pain and function change over the year after periacetabular osteotomy in people with developmental dysplasia of the hip.

What this research studies
You would join a group of about 60 people having periacetabular osteotomy (PAO) for hip dysplasia and have tests before surgery and at 6 and 12 months after. Before surgery you'll get an MRI, motion-capture walking tests, and muscle/force modeling to measure hip geometry and how your hip loads during movement. The same measurements will be repeated after surgery to see how changes in bone shape affect muscle strength, joint forces, and your symptoms. The team will use those results to define target ranges for the surgical correction that best link to improved pain and function.
Who could benefit from this research
Good fit: People (typically adolescents and young adults) with symptomatic developmental dysplasia of the hip who are scheduled to undergo periacetabular osteotomy.
Not a fit: People without hip dysplasia, those not having PAO surgery, or those with advanced hip arthritis likely needing total hip replacement are unlikely to benefit directly.
Why it matters
Potential benefit: Could help surgeons tailor PAO correction to improve pain, function, and long-term hip health for people with hip dysplasia.
How similar studies have performed: Previous work has linked abnormal hip mechanics to worse outcomes, but using combined MRI, motion capture, and modeling to set surgical target ranges is relatively new.
