Single-Blind Randomized Clinical Trial of Concomitant Hip Arthroscopy During Periacetabular Osteotomy for the Management of Hip Dysplasia
Mayo Clinic
Summary
The study will assess the outcomes of patients treated with concomitant hip arthroscopy at the time of periacetabular osteotomy (PAO) for patients with hip dysplasia compared with patients treated with PAO alone.
Description
There are currently no absolute indications for intraarticular assessment at the time of periacetabular osteotomy (PAO). Based on investigators' review of the literature and experience, patients who may benefit from intraarticular assessment are those with radiographic or MRI evidence of damage where an intraarticular inspection may help in determining whether a PAO is a reasonable procedure, those with mechanical symptoms likely related to labral pathology, round ligament or cartilage problems and those with hip dysplasia and cam deformities with limited range of motion that may benefit from…

Interventions
- ProcedurePeriacetabular 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.
- ProcedurePeriacetabular 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.
