Hip Arthroscopy Versus Total Hip Arthroplasty RCT
April 25, 2023 updated by: Ryan Degen, Western University, Canada
Clinical and Cost-effectiveness of Hip Arthroscopy Versus Definitive Total Hip Arthroplasty in 40-60 Year Olds With Early Hip Osteoarthritis: A Randomized Trial
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.

Detailed Description
The purpose of this study is to conduct a randomized trial to compare hip arthroscopy to THR and estimate the long-term cost-effectiveness. Specifically, we aim to:
- Estimate the magnitude of the between-groups difference in the primary outcome (Hip Dysfunction and Osteoarthritis Outcome Score - HOOS);
- Evaluate the clinical and cost-effectiveness of early definitive THA compared to arthroscopy for early-stage hip OA at 1-year postoperative;
- Estimate the lifetime cost-effectiveness of arthroscopy vs THA using a Markov model; and
- Identify imaging and biomechanical predictors of outcomes following hip arthroscopy

No
Description
Inclusion criteria:
- Between the ages of 40-60 years at the time of surgery.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: 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.

|
Active Comparator: 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

---|---|---|
Change in Hip Dysfunction and Osteoarthritis Outcome Score (HOOS)
Time Frame: 6 weeks, 3, 6 and 12 months
|
Subscales measuring Pain, Symptoms, Activity limitations daily living and Function in sport and recreation The outcome measure is transformed in a worst to best scale from 0 to 100, with 100 indicating no symptoms and 0 indicating extreme symptoms.

Time Frame: 6 weeks, 3, 6 and 12 months
|
The iHOT-33 is a validated, self-administered quality of life assessment tool for young, active patients with hip symptoms.
Each question is scored from 0-100 and the average for all questions is calculated, where 100 represents the best possible outcome or highest level of function.
