Hip Arthroscopy Versus Total Hip Arthroplasty RCT

Summary

The aim of the proposed study is to perform a comparative pilot, randomized controlled trial of hip arthroscopy versus definitive total hip arthroplasty (THA) for the treatment of early hip osteoarthritis (Tönnis Grade 1-2) in patients between the ages of 40-60 years.

Eligibility

Inclusion criteria:

1. Between the ages of 40-60 years at the time of surgery.
2. Radiographic evidence of mild to moderate hip OA (Tönnis Gr 0 with MRI chondral wear, Tönnis Gr 1 and 2).
3. Patients must have completed ≥3 months of non-operative management with ongoing symptoms.

Exclusion criteria:

1. Advanced OA, defined as \<2 mm joint space (Tönnis Gr 3) or those with acetabular or femoral head cysts.
2. Patients who are pregnant or may become pregnant around the time of surgery.
3. Prior arthroplasty of the contralateral hip.
4. Current or prior hip dysplasia (defined by a lateral centre edge angle of \<20 degrees).
5. Acetabular protrusio or coxa profunda, making arthroscopic access unsafe/unfeasible.
