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.

Conditions

  • Hip Osteoarthritis

Interventions

PROCEDURE

Hip Arthroscopy

Patients in the Hip Arthroscopy group will undergo arthroscopy in the supine position under general anesthesia, with all procedures performed by two subspecialty-trained hip arthroscopists. An algorithmic surgical approach will be utilized to sequentially address pathology in the central and peripheral compartments of the hip based on both preoperative imaging findings and intraoperative findings. Emphasis will be placed on labral preservation and refixation, with osseous decompression under fluoroscopic guidance.

PROCEDURE

Total Hip Arthroplasty

Patients randomized to the Total Hip Replacement (THR) group will undergo THR via a direct anterior approach. A slightly oblique skin incision measuring approximately 8 cm will be used, starting 3 cm distally and laterally to the anterosuperior iliac spine. The intervals between tensor fascia lata (TFL) and sartorius will be developed superficially, and between rectus femoris and gluteus minimus deeper. Capsulotomy will be performed. A double osteotomy of the femoral neck will be performed to facilitate removal of the head followed by traditional preparation of the acetabulum using an offset reamer and the acetabular component will be inserted. Next, the superior capsule will be released to elevate the femur to allow access to the femoral canal, followed by standard preparation by use of an offset broach and the stem will be implanted
