Purpose

The purpose of this systematic review is to evaluate the consistency of the reporting of clinical and radiographic outcomes after arthroscopic management of femoroacetabular impingement (FAI).

Methods

Two databases (Medline and EMBASE) were screened for clinical studies involving the arthroscopic management of FAI. A full-text review of eligible studies was conducted, and the references were searched. Inclusion and exclusion criteria were applied to the searched studies, and a quality assessment was completed for included studies.

Results

We identified 29 eligible studies involving 2,816 patients. There was a lack of consensus with regard to reported outcomes (clinical and radiographic) after arthroscopic treatment of FAI. Clinical outcomes reported include the Harris Hip Score (45%) and the Non-Arthritic Hip Scale (28%), range of motion (34%), pain scores (24%), and patient satisfaction (28%). The most commonly reported radiographic outcomes included the alpha angle (38%), head-neck offset (14%), and degenerative changes (21%).

Conclusions

There is significant variation in reported clinical and radiographic outcomes after arthroscopic treatment of FAI. This study highlights the need for consistent outcome reporting after arthroscopic FAI surgery.

Level of Evidence

Level IV, systematic review of Level II, III, and IV studies.

Identification of Studies

Two reviewers (M.K. and B.M.H.) searched Medline and EMBASE (1946 to June 2012) for clinical studies reporting on outcomes after arthroscopic FAI surgery. The search strategy combined the following terms: arthroscopy or hip arthroscopy, hip, impingement, and femoroacetabular impingement. All articles published during this period were reviewed for inclusion in this study.

The reviewers also completed a search of the references of recent reviews, as well as a review of the references of each

Study Identification

Our initial literature search yielded 727 studies, of which 29 met the inclusion and exclusion criteria for this review17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45 (Fig 1). There was 100% agreement between the reviewers during the study identification process.

Study Characteristics

All included studies were conducted between 2007 and 2012. The articles included in this review involved a total of 2,816 patients. Of the studies, 14 were conducted in

Key Findings

This systematic review explores the consistency of outcome reporting after arthroscopic FAI surgery and identifies significant variation in reported clinical and radiographic outcomes after arthroscopic treatment of FAI. The 3 most commonly reported clinical outcomes were the MHHS (45%), the NAHS (28%), and the WOMAC survey (18%). The most commonly reported radiographic outcomes included the alpha angle and progression of degenerative changes.

Importance of Findings

There is tremendous interest in the evaluation and

Conclusions

There is significant variation in reported clinical and radiographic outcomes after arthroscopic treatment of FAI. This study highlights the need for consistent outcome reporting after arthroscopic FAI surgery.

      Despite the large body of evidence that suggests successful outcomes in active populations, the question remains as to why coverage was not provided sooner than 2016. It is likely because of the variability of reporting clinical findings, radiographic findings, and outcomes in the literature.1-4 TRICARE is not the only health care insurance entity that has been hesitant to provide coverage for FAI surgery.

      Other studies similarly reported improved hip function,4,6 although many used the HHS,4,6 which was excluded from the MDS.12 Recent systematic reviews have suggested use of the iHOT in preference to the HHS for young to middle-aged adults with groin pain31 and encouraged standardization of outcome reporting,8 whereas a recent consensus statement encouraged routine collection of hip-specific scores (including iHOT-12) and HRQoL instruments (e.g., EQ-5D),10 both of which have been adopted in the NAHR12 and the Swedish hip arthroscopy registry.17 Surgeons who perform hip arthroscopy have also acknowledged the need for functional outcome reporting.9

      Patient-centered outcomes, primarily pain relief, were shown to be principal to identifying success after FAI surgery. Future research determining which combination of outcome scores and radiographic and advanced imaging findings is most beneficial and, potentially, future advances in cartilage biomarkers have been identified in the literature as the next steps forward in assessing successful surgical interventions.4,26 In general, most respondents agreed that weak to moderate evidence exists regarding the diagnosis and treatment of FAI.
