Brief Summary:
The purpose of this study is to compare the outcomes for patients that receive two different treatments used for FAI (Femoroacetabular Impingement). The programs are 1) a 6-week supervised physical therapy program and 2) arthroscopic surgery. Enrollment is limited to patients that have already been determined surgical candidates. The study is following patients for a 2-year period.

Condition or disease Intervention/treatment Phase
Femoroacetabular Impingement Procedure: Arthroscopic Surgery Procedure: Physical Therapy Not Applicable

Detailed Description:

This study plans to enroll a total of 60 Tricare beneficiaries primarily from the Madigan Healthcare System with a diagnosis of FAI that are surgical candidates and have already failed at least six weeks of conservative treatment.

This is a randomized controlled study comparing outcomes for the standard treatment for FAI and/or acetabular labral pathology (arthroscopy with or without labral repair) versus physical therapy. For subjects in the arthroscopy group, the surgery will be performed by the Orthopedic Surgical Service at Madigan Army Medical Center.

Subjects randomized to the physical therapy group will follow a treatment plan implemented by a physical therapist within the Madigan Army Healthcare System.

After consent, subjects will be randomized into one of two arms (Group I = hip arthroscopy, Group II = physical therapy). Group I will undergo hip arthroscopy with or without labral repair. Group II will follow a FAI-based physical therapy program x 12 sessions (6 weeks).

The arthroscopy group will complete outcome measures at time of consent and following surgery at 6 months, 1 year and 2 year time periods. Subjects in this group will follow a standardized post-operative rehabilitation protocol.

The physical therapy group will complete outcomes measures at time of consent and at 6 month, 1 year and 2 year time periods following the initial physical therapy evaluation. Subjects in this group will complete 6 weeks of an impairment-based physical therapy program.

In addition to the outcome measures taken, healthcare utilization and associated costs for hip-related care during this 2-year period will also calculated for comparison between the 2 groups.

Arm Intervention/treatment
Active Comparator: Arthroscopic Surgery
Arthroscopic surgery at the femoroacetbular joint, followed by a standardized post-operative rehabilitation protocol in physical therapy.
Procedure: Arthroscopic Surgery
The hip arthroscopy will consist of acetabular rim trimming, labral repair or debridement and femoroplasty, all as indicated based on the surgeon's clinical judgment with input from pre-operative imaging, exam findings and intra-operative findings.

Active Comparator: Physical Therapy
An impairment-based supervised in-clinic physical therapy program.
Procedure: Physical Therapy
Subjects will participate in two 45-minute sessions for six weeks (total of 12 sessions). The physical therapy treatment plan will be based on individual impairments identified during the initial evaluation, and include manual therapy to the hip, lumbar spine, and pelvis, as well as therapeutic exercise all tailored to individual patient impairments.

Primary Outcome Measures :
  1. Change from Baseline in Hip Outcome Score at 24 months [ Time Frame: 24 months ]
    The Hip Outcome Score is designed to assess higher level activities (i.e. those required in athletics) and has demonstrated validity in a study of patients at a mean of three years following hip arthroscopy. Additionally, a 2011 study states that the HOS has the greatest amount of clinimetric evidence (rigor of rating scales and indexes for the description of clinical phenomena). Only three published patient-reported outcome instruments utilized to assess FAI and labral pathology use clinimetric evidence and the HOS was identified as the most proven instrument.

  2. Change from Baseline in International Hip Outcome Score (IHOT33) to 24 months [ Time Frame: 24 months ]
    The iHOT33 is a quality-of-life patient-reported outcome measure that uses a visual analog scale response format for young, active patients with hip pathology. This 33-item questionnaire includes four sections: symptoms and functional limitations, sports and recreational activities, job related concerns and social, emotional and lifestyle concerns. This outcome measure has shown to be reliable; shows face, content and contrast validity and is highly responsive to clinical change.

Secondary Outcome Measures :
  1. Global Rating of Change [ Time Frame: 24 months ]
    The GROC will be administered to patients at the 6 months, one year and two year time points. The GROC questionnaire is a common, feasible, and useful method for assessing short term outcomes and overall changes in quality of life and is a valid measurement of change in patient status in a variety of pain populations. The GROC has a 15-point scale with a change of positive three points or higher demonstrating clinically significant improvement in a patient's perception of quality of life.

Other Outcome Measures:
  1. Self-Motivation Inventory [ Time Frame: Baseline ]
    The Self-Motivation Inventory is an outcome measure that was developed to determine level of motivation. The Self-Motivation Inventory is a 40-item tool that has been found to measure an individual's tendency to persevere independent of situational reinforcement. It has also been used to predict successful weight loss and may correlate with number of sessions attended in weight loss program [29]. This tool underwent refinement in 1980 with the original 60-item tool being tested in undergraduate male and females. Items correlating less than 0.30 were deleted. The final 40-item scale yielded an exceptionally high internal reliability (α = 0.91) suggesting that a unitary common concept is evident for the obtained factor structure. The tool is widely used and has been tested in weight loss and therapeutic exercise studies

  2. Changes from Baseline Pain Catastrophizing Scale at 24 Months [ Time Frame: 24 months ]
    The PCS is a 13-item patient-report scale developed to measure the extent to which people catastrophize in response to pain. Each item is scored from 0 ('not at all') to 4 ('all the time'). The PCS is reported as a total score, with higher scores indicating greater catastrophizing, and is composed of three sub-scales: Rumination (four items; e.g. 'When I am in pain, I keep thinking about how badly I want the pain to stop'), Magnification (three items; e.g. 'When I am in pain, I become afraid that the pain will get worse'), and Helplessness (six items; e.g. 'When I am in pain, I feel I can't go on'). The PCS has been shown to have high levels of internal consistency and construct validity.
