About this study

Official title: A Randomized Controlled Pilot Trial of Postoperative Hip Bracing After Arthroscopic Osteoplasty and Labral Repair for Femoroacetabular Impingement Syndrome

Hip arthroscopy for treatment of femoroacetabular impingement syndrome (FAIS) involves reshaping of the osseous sources of impingement ("osteoplasty") and treatment of impingement-associated labral tears with labral repair. Postoperative hip braces are advocated to decrease postoperative pain by offloading hip musculature. However there are no studies looking at efficacy of hip braces after hip arthroscopy, and on average 50% of high-volume hip arthroscopists use bracing. The objective of this study is to use a randomized controlled trial to test the cited benefits of postoperative hip bracing on short term patient reported pain scores, validated hip-specific pain scores, and physical exam findings of hip flexor tendonitis.

Read the detailed description

Hip arthroscopy for treatment of femoroacetabular impingement syndrome (FAIS) involves reshaping of the osseous sources of impingement ("osteoplasty") and treatment of impingement-associated labral tears with labral repair. The hip joint is subluxated with traction to accomplish this procedure. The diagnoses of FAIS and the incidence of hip arthroscopy have both increased dramatically in the last 20 years in the US -- in a recent study using IBM Marketscan to evaluate rates of hip arthroscopic treatment of FAIS, the investigators found this incidence doubled from 1.2 to 2.1 per 100,000 person-years in just a 3-year period. Despite the increasing incidence of hip arthroscopy in the US, on a recent review the investigators have found few evidence-based studies on postoperative care. A particular area of debate is the use of postoperative hip braces. Postoperative hip braces are advocated to decrease postoperative pain by offloading hip musculature. They may also prevent overuse of the hip flexors by supporting the hip during gait. However there are no studies looking at efficacy of hip braces after hip arthroscopy, and on average 50% of high-volume hip arthroscopists use bracing. The utility of bracing is important because hip braces are expensive (averaging $350-$600): if there are over 7000 hip arthroscopies performed nationwide and 50% of surgeons use hip braces, this amounts to over $2,000,000. The investigator's overall objective is to use a randomized controlled trial to test the cited benefits of postoperative hip bracing on short term patient reported pain scores, validated hip-specific pain scores, and physical exam findings of hip flexor tendonitis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Patient Numerical Pain Ranking Scale (NPRS)

    Validated pain scale, subject reported. Min 0, Max 10, Higher score means worse outcome.

    Measured: 6 weeks after surgery date

Secondary outcomes (6)
  1. HOOS - Hip Disability and Osteoarthritis Outcome Score

    questionnaire used to assess the patient's opinion about their hip and associated problems and to evaluate symptoms and functional limitations related to the hip during a therapeutic process. Min 0, Max 100. Lower score means worse outcome.

    Measured: at 6 week and 6 month after surgery date

  2. VR12 - Veteran RAND 12 Item Health Survey

    general health outcome survey. The results of the VR-12 are summarized as two scores - a Mental Component Score (MCS) and a Physical Component Score (PCS). The scores may be reported as Z-scores (difference compared to the population average, measured in standard deviations). The United States population average PCS and MCS are both 50 points. The United States population standard deviation is 10 points. Therefore, each increment of 10 points above or below 50 corresponds to one standard deviation away from the population average.

    Measured: at 6 week and 6 month after surgery date

  3. Patient Using Topical Non-steroidal Medication

    Number of patient using a topical nonsteroidal medication is listed here.

    Measured: 6 week and 6 month after surgery date

  4. Patient Received Cortisone Injection to Hip Flexor Sheath or Bursa

    Number of patients who received a cortisone injection to hip flexor sheath or bursa is listed here.

    Measured: 6 week and 6 month after surgery date

  5. Patient Using Opioid Medication

    Number of patients using opioids is listed here.

    Measured: 6 week and 6 month after surgery date

  6. NPRS - Numerical Pain Ranking Scale

    Validated pain scale, subject reported. Min 0, Max 10, Higher score means worse outcome.

    Measured: 6 months after surgery date
