Periacetabular Osteotomy With and Without Arthroscopic Management of Central Compartment Pathology: A Multicenter Randomized Controlled Trial
Ottawa Hospital Research Institute
Summary
At present, it is not clear whether performing a hip arthroscopy at the same time as a PAO improves patient outcomes after surgery compared to a PAO alone. This research project will randomize patients to receive either a PAO alone, or a PAO and a hip arthroscopy at the same time.
Description
Hip dysplasia is a developmental abnormality of the acetabulum (hip socket) that causes abnormal stresses inside the hip joint and leads to painful arthritis at a young age. Many patients develop painful symptoms in their hip before advanced arthritis occurs. The periacetabular osteotomy (PAO) is a surgical procedure that reorients the acetabulum to reduce the stresses inside the hip joint. The PAO is very effective at improving symptoms and quality of life. However, some patients may have residual symptoms. Frequently, people with hip dysplasia will have an MRI done before their surgery, wh…

Inclusion Criteria: * Skeletally mature patient undergoing Bernese periacetabular osteotomy for symptomatic acetabular dysplasia/hip instability * Pre-Operative MRI at 3T and/or gadolinium MR arthrogram * Age, 16-50 years old * Patient capable of giving informed consent Exclusion Criteria: * Prior hip/pelvis surgery of any kind on the surgical side * Prior hip arthroplasty surgery on either side * Radiographic evidence of arthritis (i.e. Tönnis grade =2) * Known connective tissue disorder (e.g. Ehlers-Danlos Syndrome, etc.) * Known neuromuscular disorder (e.g. Cerebral Palsy, Spina bifida,…
Interventions
- ProcedurePAO with hip arthroscopy
Participants who are randomized to the Scope-PAO group will receive central compartment hip arthroscopy in addition to the PAO.
- ProcedurePAO without hip arthroscopy
Participants who are randomized to the "PAO-only" group will receive a Bernese Periacetabular Osteotomy (PAO) for treatment of hip dysplasia.
