Interventions and Outcome Measures

Arms

experimental: Periacetabular osteotomy

Standard periacetabular osteotomy on the day of surgery.

active comparator: Periacetabular osteotomy with hip arthroscopy

Hip arthroscopy on the day of surgery, followed by a standard periacetabular osteotomy.

Interventions

Periacetabular osteotomy

The Bernese periacetabular osteotomy has become the osteotomy of choice in North America for correction of the dysplastic hip. The ability to position the acetabular component in a specifically desired position for each individual patient improves joint biomechanics, restores joint balance and stability, and offloads the structures at risk for damage such as the labrum and the adjacent articular cartilage.

Periacetabular osteotomy with hip arthroscopy

An intraarticular assessment with hip arthroscopy (HA) at the time of periacetabular osteotomy allows the surgeon to assess and treat the associated labral and chondral pathology and allows the surgeon to treat abnormalities of the femoral head junction.

Primary outcome measure

  • Mean score of Western Ontario and McMaster Universities Arthritis Index (WOMAC) [ Time Frame: 1 year follow-up time point ]
  • Mean score of University California Los Angeles (UCLA) activity assessment [ Time Frame: 1 year follow-up time point ]
  • Mean score of the Marx Activity Scale (MARX) [ Time Frame: 1 year follow-up time point ]
