Study summary

The purpose of this study is to compare the clinical response of intra-articular platelet rich plasma (PRP) versus corticosteroid injection in patients affected by femoroacetabular impingement (FAI).

Read the detailed description

This study will determine if PRP treatment of FAI improves (i) patient reported outcome scores and (ii) hip functional stability compared to standard corticosteroid treatment and if PRP treatment of FAI reduces (i) radiographic and (ii) biochemical markers of joint inflammation and cartilage degradation.

What researchers measure

Primary outcomes

  1. Change From Baseline in Pain Score on the Visual Analog Scale

    VAS score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.

    Time frame: 12 months

Secondary outcomes

  1. Hip Disability and Osteoarthritis Outcome Score (HOOS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), Calculated as a Sub-score of the HOOS

    Measure Description: Hip Disability and Osteoarthritis Outcome Score (HOOS) is a hip-specific patient-reported outcome measure that has 5 subscales. Each subscale is score separately and ranges from 0-100, 100 = no disability, therefore higher values indicate a better outcome. The WOMAC (Western Ontario and McMaster Universities) index is used to assess patients with osteoarthritis of the hip or knee and contains 24 questions, targeting areas of pain, stiffness and physical function. The WOMAC measures five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). WOMAC total is the sum of the three components and it ranges from 0 to 96 points, being 96 the worst outcome. The questions that are included in the WOMAC are a subgroup of questions that are included in the HOOS, so because of this the HOOS survey can also be used to calculate the WOMAC score for patients.

    Time frame: 12 months

  2. Patient Reported Outcome Measurement Information System (PROMIS) Global Health Scale

    Global mental health measures mental health, quality of life, satisfaction with social activities and emotional problems. Global mental health scores range from 0 - 100, and higher scores indicate better mental health. Global physical health measures overall physical health, physical function, pain and fatigue. Physical global health scores range from 0 - 100, and higher scores indicate better physical health.

    Time frame: 12 months

  3. Serum Biomarker Analysis: IFN-g, IL-6, MCP-1, MIP-1b, IL-1b, TNF-alpha, Highly Sensitive CRP, COMP.

    Time frame: 12 months

  4. Change in Kellgren-Lawrence Classification Scores

    Calculated from anterior-posterior (AP) pelvis radiographs. Kellgren Lawrence grading system was intended to be utilized analyzing pre-treatment and post-treatment radiographs of the knee. Grading is from 1 to 4 with 1 being minimal to mild disease and 4 being end stage joint disease.

    Time frame: 12 months

Limitations and caveats
Recruitment was supposed to take place in the first year, but was extended due to low enrollment. The study was terminated early due to an inability to enroll subjects. All participants left the study before outcome measure data could be collected.
