Abstract
PURPOSE To investigate the patient reported outcomes (PROs) of patients undergoing hip arthroscopy (HA) for femeroacetabular impingement syndrome (FAIS), a condition where irregular bone growth in the hip joint leads to friction and pain during movement, who have worker's compensation (WC) or no-fault insurance (NF) versus commercial insurance (CI) at both 2 year and 5 year follow-up. METHODS This was a single center, single surgeon, retrospective analysis performed between August 2007 and May 2023 of consecutive patients that underwent HA, a minimally invasive surgical procedure used to diagnose and treat problems inside the hip joint through small incisions, for FAIS. Patients were divided into two cohorts-those with WC/NF and those with commercial insurance (CI). Patient reported outcomes (PROs), which included modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS), were collected preoperatively, as well as at least 2-year postoperatively. Additionally, other clinically relevant outcomes variables including prevalence of revision surgery and conversion to total hip arthroplasty were recorded. RESULTS Three hundred and forty three patients met inclusion criteria. There were 32 patients in the WC/NF cohort and 311 patients in the commercial cohort. When controlling for age, sex, and Body Mass Index (BMI), WC/NF status was associated with lower mHHS at both 2 year (β = - 8.190, p < 0.01, R2 = 0.092) and 5 year follow-up (β = - 16.60, p < 0.01, R2 = 0.179) and NAHS at 5 year follow up (β = - 13.462, p = 0.03, R2 = 0.148). The WC/NF cohort had a lower rate of achieving Substantial Clinical Benefit (SCB) for mHHS at 2-years follow-up (66.7% vs. 84.1%, p = 0.02).The rate of revision hip arthroscopy was significantly higher in the worker's compensation/no fault cohort than the commercial insurance cohort (15.6% vs. 3.5%, p < 0.01). The rate of conversion to total hip arthroplasty (THA) in the WC/NF cohort was not significantly different than the rate of conversion to THA in the commercial insurance cohort (0.0% vs. 3.2%, p = 0.30). CONCLUSION Patients with WC/NF insurance may expect a significant improvement from baseline mHHS and NAHS following HA for FAIS at short-term follow-up. However, this improvement may not be as durable as those experienced by patients with CI. Additionally, WC/NF patients should be counseled that they have a higher risk of undergoing revision hip arthroscopy than similar CI patients.

Abstract
PURPOSE OF REVIEW Femoroacetabular impingement (FAI) is a pathomechanical process whereby abnormal contact between proximal femur and acetabulum at end range of hip motion induces chondrolabral lesions within the hip joint. Surgery followed by a rehabilitation program or physical therapy with possible addition of an intra-articular corticosteroid injection are the two predominant treatments. The majority of authors recognize that a well-designed rehabilitation protocol is essential to achieve good outcomes with both nonoperative and surgical treatment. However, there is little evidence about what is the best rehabilitation protocol and most of the literature available is based on expert level opinion. This current review investigates the recent literature on nonoperative and postoperative rehabilitation protocol and return to play in FAI patients and describes our approach. RECENT FINDINGS Historically, rehabilitation protocols for treatment of FAI as well as return to play protocols were based on experts' opinion and low-level evidence studies. In order to improve standardization of protocols and to allow a better comparison in between different protocols, different authors have created standardized rehabilitation protocols with consensus building methods comparing them with other treatment options in high-level evidence trials (FASHIoN trial, etc.). Despite the excellent results reported after nonoperative and post-surgical rehabilitation, and the high RTP rate after FAI treatment, there is a significant variability in between protocols. Further high-level evidence studies are necessary in order to establish a gold standard in rehabilitation and RTP protocols.

Abstract
BACKGROUND There are few well-studied clinical tests for the diagnosis of hip labral tears. As the differential diagnosis for hip pain is broad, accurate clinical examination is important in guiding advanced imaging and identifying patients who may benefit from surgical management. PURPOSE To determine the diagnostic accuracy of 2 novel clinical tests for the diagnosis of hip labral tears. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 2. METHODS Clinical examination findings including the Arlington, twist, and flexion-adduction-internal rotation (FADIR)/impingement tests as performed by a fellowship-trained orthopaedic surgeon specializing in hip arthroscopy were obtained from retrospective chart review. The Arlington test ranges the hip from flexion-abduction-external rotation to FADIR while applying subtle internal rotation and external rotation motion. The twist test involves internal rotation and external rotation of the hip while weightbearing. Diagnostic accuracy statistics for each of the tests were calculated using magnetic resonance arthrography as the reference standard. RESULTS A total of 283 patients were included in the study with a mean age of 40.7 years (range, 13-77 years) and 66.4% were women. The Arlington test was found to have a sensitivity of 0.94 (95% CI, 0.90-0.96), specificity of 0.33 (95% CI, 0.16-0.56), positive predictive value (PPV) of 0.95 (95% CI, 0.92-0.97), and negative predictive value (NPV) of 0.26 (95% CI, 0.13-0.46). The twist test was found to have a sensitivity of 0.68 (95% CI, 0.62-0.73), specificity of 0.72 (95% CI, 0.49-0.88), PPV of 0.97 (95% CI, 0.94-0.99), and NPV of 0.13 (95% CI, 0.08-0.21). The FADIR/impingement test was found to have a sensitivity of 0.43 (95% CI, 0.37-0.49), specificity of 0.56 (95% CI, 0.34-0.75), PPV of 0.93 (95% CI, 0.87-0.97), and NPV of 0.06 (95% CI, 0.03-0.11). The Arlington test was significantly more sensitive than both the twist and FADIR/impingement tests (P < .05), while the twist test was significantly more specific than the Arlington test (P < .05). CONCLUSION The Arlington test is more sensitive than the traditional FADIR/impingement test, while the twist test is more specific than the FADIR/impingement test in diagnosing hip labral tears in the hands of an experienced orthopaedic surgeon.

Abstract
OBJECTIVE The American Medical Association and National Institutes of Health have recommended that patient education materials should be written at the sixth-grade reading level to maximize patient comprehension. The objective of the present study was to evaluate the readability of Internet information for the 9 most common spinal surgeries. METHODS We reviewed 90 online patient educational materials regarding the 9 most common spinal surgeries as reported by the North American Spine Society. A Google search was performed on March 23, 2019 for each surgery, and the top 10 most visited websites for each surgery were assessed for reading level using the Flesch-Kincaid formula. RESULTS Using the Flesch-Kincaid formula, the average grade reading level of the 90 websites included was 12.82, with a reading ease of 37.04 ("difficult college"). Only 6 websites relayed information to patients at or below the national average of an eighth-grade reading level. The websites for bone morphogenic protein had the highest average grade reading level at 15.88 ± 2.6. Lumbar microscopic discectomy had the lowest average grade reading level at 10.37 ± 2.89. All surgical options discussed had an average readability above the recommended sixth-grade reading level. CONCLUSIONS The most accessed online materials for common spinal surgeries, not only exceeded the readability limits recommended by both the American Medical Association and the National Institutes of Health, but they also exceeded the average reading ability of most adults in the United States. Patients, therefore, might not fully comprehend the information from commonly accessed websites regarding surgical spine treatment options.

Abstract
This systematic review aims to assess the diagnosis, indications and treatment of femoroacetabular impingement (FAI) prior to the year 2000 and to determine if historical concepts remain applicable today. PUBMED, MEDLINE and EMBASE were searched for literature evaluating the diagnosis/treatment of FAI prior to 2000. Cadaver/non-human, non-English and review studies were excluded. Quality assessment was performed using the Methodological Index for Non-Randomized Studies. Nine studies comprising 307 patients [315 hips; mean age of 32.6 ± 2.4 years (range, 12-58)] were included. Patients reported groin pain. Magnetic resonance arthrography (MRA; n = 76) and the anterior impingement test (AIT) (n = 88) were used to diagnose impingement. Surgical dislocation with a trochanteric flip osteotomy (n = 237) and Bernese periacetabular osteotomy (n = 40) were common treatments. Pain and range of motion improved for patients. Overall complication rate was 35% (n = 99), with heterotopic ossification (n = 79) most commonly reported. Prior to 2000, there was low quantity and quality of research on the diagnosis/management of FAI. Diagnostic evaluation was primarily through clinical examination (i.e. groin pain and AIT). MRA was occasionally used to detect labral degeneration; however, utilization of computed tomography (CT) and diagnostic injections were not reported. Surgical dislocation and osteotomies of the acetabulum yielded desirable short-term clinical outcomes with a moderate complication rate. No study reported using arthroscopy for FAI management prior to 2000. Clinicians today can learn from historical principles (i.e. clinical diagnosis of FAI, management with surgical correction of femoral head-neck offset) while applying novel techniques (i.e. CT, injections, arthroscopic surgical techniques and rehabilitation) to improve patient outcomes. Level of Evidence IV (systematic review of III and IV evidence).

Abstract
BACKGROUND Although p values are standard for reporting statistical significance of patient-reported outcome measures (PROMs), the shift toward clinically important outcome values, including minimal clinically important difference (MCID) and substantial clinical benefit (SCB), necessitates re-evaluation of the current literature. QUESTIONS/PURPOSES We sought to answer two questions regarding studies on primary hip arthroscopy performed for the treatment of femoroacetabular impingement syndrome (FAIS). (1) Do such studies reporting statistical significance on common PROMs meet published MCID/SCB thresholds? (2) What proportion of such studies report both statistical and clinical significance? METHODS We identified four papers published in two journals defining MCID/SCB values on the modified Harris Hip Score (mHHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sport (HOS-Sport), international Hip Outcome Tool (iHOT-33), and its short version (iHOT-12) for different groups of FAIS patients undergoing hip arthroscopy. We reviewed these two journals from the dates of publication to the present to identify papers reporting changes in post-operative PROMs. The difference in pre- and post-operative scores on each PROM was calculated and compared to MCID/SCB thresholds. RESULTS Twelve studies were included. Ten studies (83%) evaluated mHHS (90% met MCID, 50% met SCB), seven (58%) evaluated HOS-ADL (100% met MCID/SCB) and HOS-Sport (100% met MCID, 57% met SCB), and one (8%) evaluated iHOT-33 (met MCID/SCB) and iHOT-12 (met MCID). Most studies met MCID and SCB at both 1- and 2-year timepoints. Of the studies evaluated, 50% reported clinical relevance. CONCLUSIONS Nearly all studies evaluated met MCID, while fewer met SCB. Only half discussed these clinical measures. It is proposed that all future studies report both statistical and clinical significance as standard best practice.

Abstract
Background The use of hip arthroscopic surgery in the treatment of femoroacetabular impingement (FAI) is increasing, but it is universally known as a technically demanding procedure with a "steep" learning curve. There are limited data investigating the correlation between surgeon experience and patient-reported outcomes (PROs) as well as procedure and traction times. Purpose To prospectively evaluate the relationship between surgeon experience and PROs after hip arthroscopic surgery for the treatment of FAI. Study Design Cohort study; Level of evidence, 2. Methods A total of 190 patients undergoing primary hip arthroscopic surgery for FAI were prospectively enrolled during a sports medicine fellowship-trained surgeon's first 36 months of practice. A radiographic evaluation as well as PRO surveys including the 12-Item Short Form Health Survey (SF-12), the modified Harris Hip Score (mHHS), and the Hip disability and Osteoarthritis Outcome Score (HOOS) were administered preoperatively and at 2 years postoperatively. Logistic regression as well as analysis of variance was performed to evaluate for correlations between surgical experience and PROs, procedure time, and traction time. Results Of the 190 patients, 168 (88%; mean age, 35.3 ± 9.6 years; mean body mass index, 25.07 ± 3.98) completed a 2-year follow-up and were included for analysis. The mean procedure time was 91.5 ± 23.9 minutes, and the mean traction time was 54.0 ± 17.7 minutes. Patients demonstrated significant improvements at 2 years after surgery for all PRO scores (mHHS, HOOS, and SF-12 physical component summary; P < .001), except the SF-12 mental component summary, which had no change (P = .43). The procedure time significantly decreased after 70 cases, while the traction time continued to decrease until 110 cases (R 2 = 0.99; P < .0001). There was no correlation between increasing case volume and 2-year PRO scores (P > .2 for mHHS, HOOS, and SF-12). There was also no difference with increasing case volume and amount of improvement from preoperative to 2-year postoperative PRO scores for the SF-12 and HOOS. Case volume did not affect the complication rate, as this cohort experienced 4 minor cases of neurapraxia. Conclusion Surgical efficiency in hip arthroscopic surgery for the treatment of FAI was maximized after 110 cases in this cohort. However, significant PRO improvements can be achieved early in a surgeon's practice prior to maximizing surgical efficiency.

The evolution of femoroacetabular impingement surgical management as a model for introducing new surgical techniques. Knee Surg Sports Traumatol Arthrosc 2020; 28:1333-1340. [PMID: 30949748 DOI: 10.1007/s00167-019-05497-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Accepted: 03/26/2019] [Indexed: 10/27/2022]
Abstract
Introducing new surgical techniques and concepts can be difficult. There are many hurdles to overcome initially, such as the learning curve, equipment and technique development, before a standard of care can be established. In the past, new surgical techniques have been developed, and even widely accepted, before any scientific evaluation has been made. At that stage, it may be too late properly to evaluate the effectiveness of treatments, as the objectiveness and/or randomisation process may be obstructed. Since the introduction of evidence-based medicine (EBM), there have been high standards of scientific rigour to prove the efficacy of treatments. Based on the nature of evidence-based acceptance, innovations cannot be subjected to this final process before their evolution process is complete and, as a result, there is a need for the staged scientific development of new surgical techniques that should be adopted. This paper presents a model for this kind of stepwise introduction based on the actual evolution of FAI syndrome surgery. By following a scientific algorithmic methodology, new surgical techniques and concepts can be introduced in a stepwise manner to ensure the evidence-based progression of knowledge.

Abstract
Purpose The purpose of this study was to evaluate the reliability and educational content of YouTube videos concerning injuries to the posterior cruciate ligament (PCL) of the knee. Methods The first 50 videos specific to the PCL identified through the YouTube query posterior cruciate ligament were evaluated by a method of video selection demonstrated to be feasible in prior YouTube studies. Videos were classified by content and upload source. Video reliability was assessed using the Journal of the American Medical Association (JAMA) benchmark criteria (score range 0-5). Video educational content was assessed using the Global Quality Score (GQS) (range 0-4) and the PCL Score (PCLS) (score range 0-18). Analysis of variance was used to determine differences in video reliability and educational content quality based on video content and upload source. Multivariate linear regressions were used to identify predictors of video reliability and educational content quality. Results The mean number of views per video was 50,477.9 ± 15,036. Collectively, the 50 videos were viewed 14,141,285 times. Video content was classified primarily as information about disease (62.0%). The most common upload sources were physicians (24.0%) and nonphysician health care providers (26.0%). Significant between-group interactions were found between video source and the JAMA score, with physicians and medical sources having significantly higher mean JAMA scores (P = 0.037). Videos uploaded by physicians were an independent positive predictor of greater JAMA scores (β:1.27; P = 0.008). Videos uploaded by a medical source (β:2.06; P = 0.038) were an independent positive predictor of a greater GQS. There were no independent associations between video content category or upload source and the PCLS. Conclusions Videos concerning the PCL were frequently viewed on YouTube, but the educational quality and reliability of these videos were low. Clinical Relevance Physicians and health care providers treating PCL pathology should take the initiative to counsel patients about which outside resources are reliable to better inform patients about their treatment decisions. With regard to YouTube videos specifically, providers should caution their patients that this source of information may be unreliable.

Abstract
Purpose To report the return-to-duty rate and surgical outcomes in a military population after mini-open arthroscopic-assisted surgery for femoroacetabular impingement (FAI) in an effort to affirm its efficacy. Methods A retrospective review of consecutive active-duty patients receiving mini-open arthroscopic-assisted surgery for FAI between 2007 and 2011 was performed. Patients younger than 18 years, non–active-duty patients, and patients with prior hip surgery were excluded. Demographic, radiographic, and duty-status data were collected. The primary outcome measure was a return to duty. Outcome scores were obtained in a proportion of the cohort, including the modified Harris Hip Score, Single Assessment Numeric Evaluation score, Western Ontario and McMaster Universities Osteoarthritis Index score, patient satisfaction score, and Veterans RAND 12 (VR-12) score. All patients had achieved a minimum of 1 year of follow-up at the time of assessment. All P values for significance were set at .05 or lower. Results Of 182 patients (average age, 30.4 years), 156 (86%) were available for follow-up with return-to-duty data at an average of 2.8 years (range, 1-6 years). Of the patients, 78% returned to full duty (53%) or returned to duty with restrictions (25%). Outcome scores were available for 101 of 182 patients (55%) with duty rates similar to the total cohort (81% who returned to duty: 58% with no restrictions and 23% with restrictions). Return to duty correlated with improved outcomes compared with those who were medically discharged with respect to the modified Harris Hip Score (68.2 vs 54.5, P < .03), Single Assessment Numeric Evaluation score (48.2 vs 25.3, P < .02), and VR-12 physical (39.7 vs 33.2, P < .05) and VR-12 mental (54.5 vs 43.4, P < .005) scores. Conclusions Mini-open arthroscopic-assisted surgery for FAI is successful in returning most service members to duty at short-term follow-up. Return correlates with improved outcome scores, although previously reported minimally clinical important difference and patient acceptable symptomatic state threshold values were not uniformly achieved. Level of Evidence Level IV, retrospective case series.

Abstract
The field of hip arthroscopy has undergone considerable change in the past 25 years and continues to evolve at a rapid pace. Lessons from the early complications and challenges of hip arthroscopy have led to improved safety and refinement of instrumentation and techniques. The pathophysiology of hip injuries is better understood, and advances in surgical technique have helped expand indications, particularly as a shift from pathology resection to anatomic repair and reconstructive procedures has occurred. As the field has progressed, longitudinal outcome studies are now available to help judge efficacy. The purpose of this review is to highlight the past 30 years of hip arthroscopy, the current practice trends, and future directions of the field.

Abstract
Femoroacetabular impingement has been established as an impactful cause of hip pain and dysfunction in the young active individual. Improving evidence from well-conducted studies will continue to refine indications and outcomes and perhaps lead to more questions, such as: "How was the capsule managed?" "What was the patient compliance rate with rehabilitation?" "What was the impact of surgical morphology correction on clinical outcome?" "Did cartilage status impact clinical outcome?" and "Was there a noticeable learning curve reflected in outcomes?" These are all important questions that should be addressed in future studies.

Abstract
BACKGROUND Hip arthroscopy has emerged as a successful option for the treatment of femoroacetabular impingement and related hip disorders, but the procedure is technically challenging. PURPOSE To define the learning curve through which surgeons become proficient at hip arthroscopy. STUDY DESIGN Cohort study; level of evidence, 3. METHODS The authors identified hip arthroscopy procedures performed by surgeons through a New York State database (Statewide Planning and Research Cooperative System) and followed those cases for additional hip surgery (total hip arthroplasty, hip resurfacing, or ipsilateral hip arthroscopy) within 5 years of the original procedure. Career volume for each case was calculated as the number of hip arthroscopy procedures that the surgeon had performed. Volume strata were identified via the stratum-specific likelihood ratio method. A Cox proportional hazards model was used to measure the effect of surgeon career volume on risk of additional hip surgery, adjusting for the following patient characteristics: age, sex, race/ethnicity, insurance type, and concurrent diagnosis of hip osteoarthritis. RESULTS Among 8041 hip arthroscopies performed by 251 surgeons, 989 (12.3%) cases underwent additional hip surgery within 5 years. Four strata of surgeon career volume associated with distinct frequencies of reoperation were identified: cases in the lowest stratum (0-97) had the highest frequency of additional surgery (15.4%). Frequencies declined for cases in the medium (98-388), high (389-518), and highest (≥519) strata (13.8%, 10.1%, and 2.6%, respectively). There was an increased risk of subsequent surgery in each stratum when compared with the highest stratum (hazard ratio [95% CI]: low volume, 3.22 [2.29-4.54]; medium, 3.40 [2.41-4.82]; high, 2.81 [1.86-4.25]; P < .0001 for all). Patients with a diagnosis of hip osteoarthritis had increased risk of subsequent hip arthroplasty or resurfacing (2.46 [2.09-2.89], P < .0001) . Risk also increased with age: 30 to 39 vs ≤29 years (5.12 [3.29-8.00], P < .0001), 40 to 49 vs ≤29 years (11.30 [7.43-17.190], P < .0001), ≥50 vs ≤29 years (18.39 [12.10-27.96], P < .0001). Increased age and osteoarthritis were not risk factors for revision hip arthroscopy. CONCLUSION The learning curve for hip arthroscopy was unexpectedly demanding. Cases performed by surgeons with career volumes ≥519 had significantly lower risk of subsequent hip surgery than those performed by lower-volume surgeons.

Abstract
Femoroacetabular impingement (FAI) is a common cause of hip pain that can affect a wide range of patients. It is due to altered bony morphology of the proximal femur and acetabulum, resulting in decreased function and progression to early osteoarthritis. Until the early 2000s, little was known or understood about the significance of FAI as a clinical entity. The field of hip preservation has grown exponentially since that time, and has led to many advances in caring for those with symptomatic impingement. This review details the early diagnosis and proper management of femoroacetabular impingement for the sports medicine practitioner.

Abstract
BACKGROUND Hip arthroscopy utilization has increased dramatically over the last decade. However, the lack of a formal training curriculum raises concern that inconsistent technical performance may be an issue for early-career hip arthroscopists. The purpose of the present study was to investigate hip arthroscopy utilization by early-career orthopaedic surgeons while focusing on fellowship training status to better guide future development of a hip arthroscopy training curriculum. METHODS The American Board of Orthopaedic Surgery (ABOS) Part-II database was used to identify candidates who had performed ≥1 hip arthroscopy procedures between 2006 and 2015. Procedures were categorized using Common Procedural Terminology (CPT) codes, and candidates were categorized by fellowship training experience. Trends in hip arthroscopy utilization were evaluated using univariate and regression analyses while stratifying by fellowship training experience. RESULTS Overall, 9.2% (643) of 6,987 ABOS candidates had performed ≥1 hip arthroscopy procedures. Over the study period, both the proportion of candidates performing hip arthroscopy and the proportion of hip arthroscopy procedures performed (relative to all procedures performed, of any type) increased (p < 0.001). Candidates performing hip arthroscopy most frequently reported sports medicine fellowship training (74.5%; 479 of 643). Also, among the candidates who performed hip arthroscopy, the proportion who had sports medicine fellowship training increased over the study period (p = 0.001). The majority of candidates performing hip arthroscopy (67.2%; 432 of 643) performed ≤5 hip arthroscopy procedures, while a small number of high-volume hip arthroscopists (6.5%; 42 of 643) performed 34.6% (1,403 of 4,054) of all hip arthroscopy procedures. CONCLUSIONS The increase in hip arthroscopy utilization in this cohort appears to have been driven primarily by the increased number of candidates performing hip arthroscopy and less by an increasing number of hip arthroscopy procedures being performed by individual candidates. The majority of candidates performing hip arthroscopy were sports-medicine-fellowship trained. This information is valuable for both trainees and educators interested in improving education and defining a curriculum for future hip arthroscopy training.

Abstract
The purpose of this study is to define the incidence of hip arthroscopy-related procedures in the United States prior to and following 2011 and to determine if the rise in incidence has coincided with an increase in the complexity and diversity of procedures performed. Patients who underwent hip arthroscopy were identified from a publicly available US database. A distinction was made between 'traditional' and 'extended' codes. CPT-29999 (unlisted arthroscopy) was considered extended and counted only if associated with a hip pathology diagnosis. Codes directed toward femoroacetabular impingement pathology were also considered extended codes and were analyzed separately based on increased technical skill. Unpaired student t-tests and z-score tests were performed. From 2007 to 2014, there were a total of 2581 hip arthroscopies performed in the database (1.06 cases per 10 000 patients). The number of hip arthroscopies increased 117% from 2007 to 2014 (P < 0.001) and 12.5% from 2011 to 2014 (P = 0.045). Hip arthroscopies using extended codes increased 475% from 2007 to 2014 (P < 0.001) compared to 24% for traditional codes (P < 0.001). Codes addressing femoroacetabular impingement (FAI) pathology increased 55.7% between 2011 to 2014 (P < 0.001). The ratio of labral repair to labral debridement in patients younger than 50 years exceeded >1.0 starting in 2011 (P < 0.001). The total number of hip arthroscopies in addition to the complexity and diversity of hip arthroscopy procedures performed in the United States continues to rise. FAI-based procedures and labral repairs are being performed more frequently in younger patients, likely reflecting both improved technical ability and current evidence-based research.

Abstract
PURPOSE This review provides a bibliometric analysis of the contributors to the field of FAI research. METHODS A comprehensive search of three databases (MEDLINE, EMBASE, and PubMed) was performed to identify all clinical research articles on the topic of FAI (from inception to 2015). Cadaveric and animal studies were excluded. Study characteristics including authors, residing country of corresponding author, and journal were abstracted from the respective databases. RESULTS In total, 1073 articles were included in this review. There were a total of 5471 different authors who contributed to the field of FAI research, 28.3 % of whom were only published in one article. The top 20 authors were associated with over half of all publications, and research studies were typically performed in their countries of residence. The greatest proportion of FAI-related articles was published in the Journal of Arthroscopy and Clinical Orthopaedics and Related Research. CONCLUSIONS The number of authors contributing to FAI research is increasing, suggesting not only increasing prevalence of FAI treatment among orthopaedic surgeons but also increasing interest among hip arthroscopists in furthering understanding regarding the diagnosis and management of the condition. The number of publications produced by the top 20 authors (and their affiliated countries: USA, Switzerland, Canada, and the UK) is expected to contribute to a majority of future publications. Current trends suggest that the quality of evidence will continue to improve in the near future, as large-scale, collaborative studies are currently underway.

Abstract
A systematic review was performed to explore the current trends over the last 5 years in femoroacetabular impingement (FAI) literature and compare the quality and sources of publications in the literature to that published previously. We identified 1066 relevant studies including 186,572 patients. The number of publications increased during the reviewed time period with the most dramatic increase from 2011 to 2013. Seventy-three percent (N = 786) of all studies were of levels 4 and 5 quality evidence. The percent of publications which were levels 1, 2 and 3 increased by almost twofold from 16.1 % (N = 26) to 28.7 % (N = 51) between 2011 and 2015. In comparison to previous work, there has been 3.5-fold increase in the number of publications over the past 5 years with a shift towards improving the level of evidence available guiding the arthroscopic management of FAI.

Abstract
PURPOSE Surgical hip dislocation (SHD) and hip arthroscopy are surgical methods used to correct deformity associated with femoroacetabular impingement (FAI). Though both of these approaches appear to benefit patients, no studies exist comparing healthcare resource utilization of the two surgical approaches. This systematic review examines the literature and the records of two surgeons to evaluate the resource utilization associated with treating symptomatic FAI via these two methods. METHODS EMBASE, MEDLINE and PubMed were searched for relevant articles. The articles were systematically screened, and data was abstracted in duplicate. To further supplement resource utilization data, a retrospective chart review of two surgeon's patient data (one using SHD and another using an arthroscopic approach) was completed. Experts in pharmacy, physiotherapy, radiology, anaesthesia, physiatry and the local hospital finance department were also consulted. RESULTS There were 52 studies included with a total of 460 patients (535 hips) and 3886 patients (4147 hips) who underwent SHD and arthroscopic surgery for FAI, respectively. Regardless of approach, most patients treated for symptomatic FAI improved across various outcomes measures with low complication rates. Surgical time across all approaches was similar, averaging 118 ± 2 min. On a per patient basis, hip arthroscopy ($10,976) uses approximately 41 % of the resources of SHD ($24,379). CONCLUSION There were no significant differences in outcomes for FAI treated with SHD or arthroscopy. However, with regard to healthcare resource utilization based on the OHIP healthcare system, hip arthroscopy uses substantially less resources than SHD within the first post-operative year.

Abstract
PURPOSE This international survey was conducted to assess the perceptions of orthopaedic surgeons regarding the diagnosis and management of femoroacetabular impingement (FAI) as well as to explore the current demographic characteristics of surgeons performing FAI surgery. METHODS A survey was developed using previous literature, focus groups, and a sample-to-redundancy strategy. The survey contained 46 questions and was e-mailed to national orthopaedic associations and orthopaedic sports medicine societies for member responses. Members were contacted on multiple occasions to increase the response rate. RESULTS Nine hundred orthopaedic surgeons from 20 national and international organizations completed the survey. Surgeons responded across 6 continents, 58.2% from developed nations, with 35.4% having sports fellowship training. North American and European surgeons reported significantly greater exposure to hip arthroscopy during residency and fellowship training in comparison to international respondents (48.0% and 44.5% respectively, v 25.6%; P < .001). Surgeons performing a higher volume of FAI surgery (> 100 cases per year) were significantly more likely to have practiced for more than 20 years (odds ratio [OR], 1.91; 95% confidence interval [CI], 1.01 to 3.63), to be practicing at an academic hospital (OR, 2.25; 95% CI, 1.22 to 4.15), and to have formal arthroscopy training (OR, 46.17; 95% CI, 20.28 to 105.15). High-volume surgeons were over two-fold more likely to practice in North America and Europe (OR, 2.26; 95% CI, 1.08 to 4.72). CONCLUSIONS The exponential rise in the diagnosis and surgical management of FAI appears to be driven largely by experienced surgeons in developed nations. Significant variability exists regarding the diagnosis and management of FAI. Our analysis suggests that although FAI management is early in the innovation cycle, we are at a tipping point toward wider uptake and use.

PURPOSE To evaluate any trends in the level of clinical evidence in the papers presented at the Arthroscopy Association of North America (AANA) annual scientific meetings from 2006 to 2015. METHODS The online abstracts of the paper presentations presented at the AANA meetings were independently evaluated by 2 reviewers (664 total presentations). The reviewers independently screened these results for clinical studies and graded their level of evidence from Level I (i.e., randomized trials) to IV (i.e., case series) based on the American Academy of Orthopaedic Surgeons classification system. RESULTS Five hundred thirteen presentations met the inclusion criteria and were evaluated. Overall, 16% of the presentations were Level I evidence, 15% were Level II, 26% were Level III, and 43% were Level IV. We observed a significant non-random improvement in the level of evidence of presentations at the AANA meetings (P ≤ .001) between 2006 and 2015. In particular, the percentage of papers with Level IV evidence presented significantly decreased (P ≤ .001) and the percentage of papers with Level III evidence increased (P = .004) over the study period. CONCLUSIONS Statistical trends show that the influence of evidence-based medicine in orthopaedics has had a positive impact on the quality of research presented at the AANA meetings. LEVEL OF EVIDENCE Level IV, review of abstracts of Level I to Level IV evidence.

Abstract
Femoroacetabular impingement (FAI) is characterized by an abnormality in the shape of the femoral head-neck or acetabulum that results in impingement between these two structures. Arthroscopic treatment has become the preferred method of management of FAI owing to its minimally invasive approach. Surgical correction involves resection of impinging osseous structures as well as concurrent management of the associated chondral and labral pathology. Research from the past 5 years has shown that repair of the labrum results in a better anatomic correction and improved outcomes compared with labral debridement. Research is underway to improve cartilage assessment by using innovative imaging techniques and biochemical tests to inform predictions of prognosis. Several ongoing randomized controlled trials, including the Femoroacetabular Impingement Trial (FAIT) and the Femoroacetabular Impingement Randomized Controlled Trial (FIRST), will provide critical information regarding the diagnosis, management and prognosis of patients undergoing arthroscopic management of FAI.

Abstract
Health care facilities produce significant waste (2200 kg/bed/year) creating 2% of greenhouse gas emissions and 1% total solid waste nationwide, with 20–70% of waste coming from operating rooms. We performed a waste audit of hip arthroscopy for femoroacetabular impingement (FAI) to understand its environmental impact and identify areas for greening practices. A waste audit of five hip arthroscopy procedures for FAI was performed. All waste was collected and separated into six waste streams in real time: (i) normal/landfill waste; (ii) recyclable cardboards and plastics; (iii) biohazard waste; (iv) sharp items; (v) linens and (vi) sterile wrapping. The surgical waste (except laundered linens) from five FAI surgeries totaled 47.4 kg, including 21.7 kg (45.7%) of biohazard waste, 11.7 kg (24.6%) of sterile wrap, 6.4 kg (13.5%) of normal/landfill waste, 6.4 kg (13.5%) of recyclable plastics and 1.2 kg (2.6%) of sharp items. An average of 9.4 kg (excluding laundered linens) of waste was produced per procedure. Given the considerable biohazard waste produced by FAI procedures, additional recycling programs, continued adherence to proper waste segregation and an emphasis on ‘green outcomes’ is encouraged to demonstrate environmental responsibility and effectively manage and allocate finite resources.

Abstract
Femoro-acetabular impingement (FAI) is increasingly recognized as an important cause of hip pain in the young adult. However, the methods of evaluating the efficacy of surgical intervention are often not validated and/or inconsistently reported. Important clinical, gait, radiographic and biomarker outcomes are discussed. This article (1) presents the rationale for considering a composite outcome for FAI patients; (2) examines a variety of important end points currently used to evaluate FAI surgery; (3) discusses a strategy to generate a composite outcome by combining these end points; and (4) highlights the challenges and current areas of controversy that such an approach to evaluating symptomatic FAI patients may present.

Abstract
PURPOSE To provide a comprehensive review and summary of the research published in Arthroscopy: The Journal of Arthroscopic and Related Surgery and The American Journal of Sports Medicine (AJSM) related to hip arthroscopy for femoroacetabular impingement (FAI). METHODS A comprehensive review was conducted in duplicate of Arthroscopy and AJSM from February 2012 to February 2015 for all articles related to FAI, and a quality assessment was completed for all included studies. Clinical outcomes were dichotomized into short-term (<6 months) and midterm (<24 months) outcomes, and values were pooled when possible. RESULTS We identified 60 studies in Arthroscopy and 44 studies in AJSM, primarily from North America (78.8%), that predominantly assessed clinical outcomes after arthroscopic hip surgery (46.1%). Seventy-one percent of Arthroscopy studies and 20.5% of AJSM studies were Level IV evidence. The modified Harris Hip Score (mHHS) was used by 81.5% of included studies. Pooled weighted mean mHHS values after arthroscopic surgery for FAI showed improvements at the midterm from 60.5 points (range, 56.6 to 83.6 points) to 80.5 points (range, 72.1 to 98.0 points) out of a possible 100 points. Pooled weighted outcomes for labral repair showed mean mHHS improvements from 63.8 points (range, 62.5 to 69.0 points) preoperatively to 86.9 points (range, 85.5 to 89.9 points) up to 24 months postoperatively. CONCLUSIONS This comprehensive review of research published in Arthroscopy and AJSM over the past 3 years identified a number of key findings. Arthroscopic intervention results in improvements in functional outcomes at both the short-term and midterm for patients with symptomatic FAI in the absence of significant existing degenerative changes. Labral repair may result in improvements over labral debridement. The most commonly used outcome score was the mHHS for objective assessment of surgical success. There is a need for continued focus on improvement of methodologic quality and reporting of research pertaining to FAI. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.

Abstract
The International Society for Hip Arthroscopy (ISHA) Annual Scientific Meeting is at the forefront of informing today's orthopaedic surgeons and society of the rapid advances in the exponentially growing field of hip arthroscopy. The purpose of this study was to evaluate and observe any trends in the level of clinical evidence in the papers and posters presented at the ISHA Annual Scientific Meeting from 2010 to 2014. The online abstracts of the paper and poster presentations presented at the ISHA Annual Scientific Meetings were independently evaluated by two reviewers (582 total resulting presentations). Two reviewers screened these results for clinical studies and graded the quality of evidence from level I (i.e. randomized trials) to IV (i.e. case series) based on the American Academy of Orthopaedic Surgeons classification system. Four hundred and twenty-eight presentations met the inclusion criteria and were evaluated. Overall, 10.1% of the presentations were level I, 12.8% were level II, 30.1% were level III and 47.0% were level IV evidence. Over time, from 2010 to 2014, we observed an increase in the percentage of level II paper presentations, an increase in the proportion of level III poster presentations, and a decrease in the proportion of both level IV paper and poster presentations. Significant non-random improvement in the level of evidence presented was noted for the poster presentations (P = 0.012) but not for the paper presentations (P = 0.61) over the study period. Statistical trends demonstrate ISHA's increased awareness and commitment to presenting higher quality evidence as the availability of this evidence increases.

Methodological quality of systematic reviews addressing femoroacetabular impingement. Knee Surg Sports Traumatol Arthrosc 2015; 23:2583-9. [PMID: 25037984 DOI: 10.1007/s00167-014-3151-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2014] [Accepted: 06/19/2014] [Indexed: 01/11/2023]
Abstract
PURPOSE As the body of literature on femoroacetabular impingement (FAI) continues to grow, clinicians turn to systematic reviews to remain current with the best available evidence. The quality of systematic reviews in the FAI literature is currently unknown. The goal of this study was to assess the quality of the reporting of systematic reviews addressing FAI over the last 11 years (2003-2014) and to identify the specific methodological shortcomings and strengths. METHODS A search of the electronic databases, MEDLINE, EMBASE and PubMed, was performed to identify relevant systematic reviews. Methodological quality was assessed by two reviewers using the revised assessment of multiple systematic reviews (R-AMSTAR) scoring tool. An intraclass correlation coefficient (ICC) with 95 % confidence intervals (CI) was used to determine agreement between reviewers on R-AMSTAR quality scores. RESULTS A total of 22 systematic reviews were assessed for methodological quality. The mean consensus R-AMSTAR score across all studies was 26.7 out of 40.0, indicating fair methodological quality. An ICC of 0.931, 95 % CI 0.843-0.971 indicated excellent agreement between reviewers during the scoring process. CONCLUSIONS The systematic reviews addressing FAI are generally of fair methodological quality. Use of tools such as the R-AMSTAR score or PRISMA guidelines while designing future systematic reviews can assist in eliminating methodological shortcomings identified in this review. These shortcomings need to be kept in mind by clinicians when applying the current literature to their patient populations and making treatment decisions. Systematic reviews of highest methodological quality should be used by clinicians when possible to answer clinical questions.

A multi-centre randomized controlled trial comparing arthroscopic osteochondroplasty and lavage with arthroscopic lavage alone on patient important outcomes and quality of life in the treatment of young adult (18-50) femoroacetabular impingement. BMC Musculoskelet Disord 2015; 16:64. [PMID: 25886958 PMCID: PMC4387581 DOI: 10.1186/s12891-015-0500-y] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2014] [Accepted: 02/12/2015] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Several cross-sectional studies have estimated that the prevalence of femoroacetabular impingement (FAI) ranges from 14-17% among asymptomatic young adults to almost 95% among competitive athletes. With FAI, there is abnormal contact between the proximal femur and the acetabulum, resulting in abnormal mechanics with terminal motion such as hip flexion and rotation. This condition results from bony anomalies of the acetabular rim (Pincer) and or femoral head/neck junction (CAM) and typically causes hip pain and decreased hip function. The development of hip pain potentially serves as an indicator for early cartilage and labral damage that may result in hip osteoarthritis. Although surgical correction of the misshaped bony anatomy and associated intra-articular soft tissue damage of the hip is thought to improve hip pain and alter the natural history of degenerative disease, the supportive evidence is based upon low quality observational studies. The Femoroacetabular Impingement RandomiSed controlled Trial (FIRST) compares outcomes following surgical correction of the impingement morphology (arthroscopic osteochondroplasty) with/without labral repair versus arthroscopic lavage of the hip joint in adults aged 18 to 50 diagnosed with FAI. METHODS AND DESIGN FIRST is a multi-centre, randomized controlled trial with a sample size of 220 patients. Exclusion criteria include the presence of hip syndromes, previous surgery or trauma to the affected hip, and significant medical comorbidities. The primary outcome is pain and the secondary outcomes include patient function, quality of life, complications, and cost-effectiveness--all within one year of follow-up. Patients are stratified based on centre and impingement sub-type. Patients, outcome assessors, data analysts, and the Steering Committee are blinded to surgical allocation. Using an intention-to-treat approach, outcome analyses will be performed using an analysis of covariance and descriptive statistics. DISCUSSION Symptomatic FAI is associated with chronic hip pain, functional limitations, and secondary osteoarthritis. Therefore, optimizing treatment has the potential to improve the lives millions of young, active persons who are diagnosed with this condition. Few orthopaedic surgical trials have similar potential to shift the paradigm of care dramatically towards (or away) from surgical bony and soft tissue interventions. TRIAL REGISTRATION The FIRST trial is registered with clinicaltrials.gov (NCT01623843).

Abstract
PURPOSE This study was carried out to assess the quality of information available on YouTube regarding femoroacetabular impingement (FAI). METHODS YouTube was searched on September 7, 2013 using the search terms FAI, femoroacetabular impingement, and hip impingement. Analysis was restricted to the first 3 pages of results for each search term. English language was a prerequisite for inclusion. Videos were evaluated by 2 independent reviewers (M.G.M., D.J.H.) using novel scoring checklists for diagnosis and treatment of FAI. Interobserver reliability analysis was evaluated using the intraclass correlation coefficient (ICC). Videos were grouped according to quality assessment score, and the group means were analyzed for differences in video characteristics using the analysis of variance (ANOVA) model. Videos were characterized by the source of content. RESULTS After filtering 1,288,324 potential videos, 52 videos were identified and included for analysis. The mean video quality assessment scores were 3.1 for diagnosis and 2.9 for treatment (maximum score = 16). No videos were scored as excellent (quality assessment score > 12). Effective resources included 3 videos on diagnosis and one video on treatment. No statistically significant differences were found between high- and low-scoring videos for duration, days online, views per day, likes, likes per day, likes per view, dislikes, or likes-dislikes difference for either diagnosis or treatment (P > .05 for all). The source of most of the videos was educational (67%), and most of these included physicians (66%). CONCLUSIONS Patients searching YouTube for videos pertaining to FAI will be presented with a sizeable repository of content of overall low quality. As such, physicians need to recognize the potential influence of YouTube videos on patients' preconceptions of their conditions and the effect on the physician-patient consultation. This review highlights the need for evidence-based, comprehensive educational videos addressing FAI diagnosis and treatment.

Abstract
PURPOSE The purpose of this study was to review the global pattern of surgical management of femoroacetabular impingement (FAI), particularly in diagnosis, outcome measurement, and management. METHODS We performed a systematic search in duplicate for surgical studies addressing FAI published up to June 2013. Study parameters, including sample size, study location, surgical intervention technique, diagnostic imaging, outcome measures used, sex distribution, and level of evidence, were obtained. The number of trials and cumulative sample size were analyzed. The surgical interventions, sex distribution, outcome measures, and diagnostic imaging used were compared between geographic regions. RESULTS We identified 105 studies reporting surgical interventions for FAI. Most studies were completed in North America (52 studies, 3,629 patients) and in Europe (44 studies, 3,745 patients). Asia (3 studies, 49 patients) and Oceania (6 studies, 394 patients) had smaller contributions. There were no studies from South America or Africa. Most research performed in North America, Europe, and Oceania investigated arthroscopic FAI surgery (55% of studies) followed by surgical dislocation (33%), and miniopen (15%) and combined approaches (8%). Methods of diagnosis were consistent worldwide, with radiography being the mainstay of diagnosis (84% of studies). Case series were the most common type of study globally (75% of studies). Outcome measures varied by region; Harris hip scores were most common in North America, Oceania, and Asia, whereas Non-Arthritic Hip Scores and Western Ontario McMaster scores predominated in Europe. CONCLUSIONS Global surgical trends for FAI show a predominance of North American and European studies, studies of lower level evidence, and inconsistent use of outcome measures. However, patterns of diagnostic imaging, sex proportions, and predominance of arthroscopic techniques are consistent worldwide. Future research should focus on development of reliable validated outcome measures and international collaboration to conduct high-quality research and improve our understanding of FAI diagnosis and management.

Abstract
BACKGROUND AND AIMS Femoroacetabular impingement is the abnormal contact of the proximal femur and acetabulum during motion. It causes hip pain and joint degeneration in young patients. This systematic review aims to clarify the clinical effect of arthroscopic femoral osteochondroplasty for cam lesions and to review the available literature for the general medical readership, including providers of primary and secondary care. METHODS AND RESULTS Electronic databases were searched for studies of arthroscopic femoral osteochondroplasty in primary femoroacetabular impingement. A total of 2618 article titles, 242 abstracts and 33 full text articles were considered. Ultimately nine studies with clinical outcome scores met the inclusion criteria and were included in the qualitative systematic review. Six studies were suitable for meta-analysis using an inverse variance, random effects model (RevMan software). In the nine studies, improvements were seen in Western Ontario and McMaster Universities Osteoarthritis index, Non-arthritic Hip Score and Modified Harris Hip Scores. Across the six studies suitable for meta-analysis (537 patients), a 24-point weighted mean improvement in Non-arthritic hip score was seen. This yielded a large overall effect size of 1.6. CONCLUSION Arthroscopic femoral osteochondroplasty appears to be a beneficial treatment for primary femoroacetabular impingement, with a large effect size seen across six eligible studies.

Abstract
BACKGROUND Surgery is sometimes recommended for femoroacetabular impingement where non-operative interventions have failed. OBJECTIVES To determine the benefits and safety of surgery for femoroacetabular impingement. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 11); MEDLINE (Ovid) (1946 to 19 November 2013); and EMBASE (Ovid) (1980 to 19 November 2013) for studies, unrestricted by language. SELECTION CRITERIA Randomised and quasi-randomised clinical trials assessing surgical intervention compared with placebo treatment, non-operative treatment or no treatment in adults with femoroacetabular impingement. DATA COLLECTION AND ANALYSIS Two authors independently selected trials for inclusion, assessed risk of bias and extracted data. MAIN RESULTS There were no studies that met the inclusion criteria, with 11 studies that were excluded following detailed review. There were four ongoing studies identified that may meet the inclusion criteria when they are completed; the results from these ongoing studies may begin to become available within the next five years. Three of the four ongoing studies are comparing hip arthroscopy versus non-operative care. The fourth study is comparing hip arthroscopy versus a sham arthroscopic hip procedure. All of the ongoing studies are recording at least one of our preferred clinical outcome measures for benefit and safety. AUTHORS' CONCLUSIONS There is no high quality evidence examining the effectiveness of surgery for femoroacetabular impingement. There are four ongoing studies, which may provide evidence for the benefit and safety of this type of surgery in the future.

Abstract
Background: A diagnosis of femoroacetabular impingement (FAI) requires careful history and physical examination, as well as an accurate and reliable radiologic evaluation using plain radiographs as a screening modality. Radiographic markers in the diagnosis of FAI are numerous and not fully validated. In particular, reliability in their assessment across health care providers is unclear. Purpose: To determine inter- and intraobserver reliability between orthopaedic surgeons and musculoskeletal radiologists. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Six physicians (3 orthopaedic surgeons, 3 musculoskeletal radiologists) independently evaluated a broad spectrum of FAI pathologies across 51 hip radiographs on 2 occasions separated by at least 4 weeks. Reviewers used 8 common criteria to diagnose FAI, including (1) pistol-grip deformity, (2) size of alpha angle, (3) femoral head-neck offset, (4) posterior wall sign abnormality, (5) ischial spine sign abnormality, (6) coxa profunda abnormality, (7) crossover sign abnormality, and (8) acetabular protrusion. Agreement was calculated using the intraclass correlation coefficient (ICC). Results: When establishing an FAI diagnosis, there was poor interobserver reliability between the surgeons and radiologists (ICC batch 1 = 0.33; ICC batch 2 = 0.15). In contrast, there was higher interobserver reliability within each specialty, ranging from fair to good (surgeons: ICC batch 1 = 0.72; ICC batch 2 = 0.70 vs radiologists: ICC batch 1 = 0.59; ICC batch 2 = 0.74). Orthopaedic surgeons had the highest interobserver reliability when identifying pistol-grip deformities (ICC = 0.81) or abnormal alpha angles (ICC = 0.81). Similarly, radiologists had the highest agreement for detecting pistol-grip deformities (ICC = 0.75). Conclusion: These results suggest that surgeons and radiologists agree among themselves, but there is a need to improve the reliability of radiographic interpretations for FAI between the 2 specialties. The observed degree of low reliability may ultimately lead to missed, delayed, or inappropriate treatments for patients with symptomatic FAI.

Abstract
Context: Several risk factors may cause femoroacetabular impingement (FAI). Knowledge of causation would identify patients for early intervention, prior to the development of painful intra-articular damage. Data Sources: PubMed, MEDLINE, EMBASE, and related article reference lists were screened for relevant studies published between January 2000 and December 2013. Study Selection: Inclusion criteria were (1) etiology of FAI, (2) original FAI clinical data, and (3) English language. Case reports of fewer than 3 patients were excluded. Study Design: Systematic review. Level of Evidence: Level 4. Results: In all, 754 studies were screened, with 18 meeting the eligibility criteria. There were 13 comparative observational studies and 5 case series. The studies pertained to intrinsic patient factors (n = 2), activity/developmental factors (n = 8), hip disease (n = 5), postsurgical changes (n = 2), and malunion after hip fracture (n = 1). Conclusion: A combination of intrinsic patient and developmental factors, activities involving repetitive hip motion, pediatric hip disease, and hip-related surgical procedures may contribute to the development of FAI.

Abstract
PURPOSE The learning curve for hip arthroscopy is consistently characterized as "steep." The purpose of this systematic review was to (1) identify the various learning curves reported in the literature, (2) examine the evidence supporting these curves, and (3) determine whether this evidence supports an accepted number of cases needed to achieve proficiency. METHODS The electronic databases Embase and Medline were screened for any clinical studies reporting learning curves in hip arthroscopy. Two reviewers conducted a full-text review of eligible studies and a hand search of conference proceedings and reference sections of the included articles. Inclusion/exclusion criteria were applied, and a quality assessment was completed for each included article. Descriptive statistics were compiled. RESULTS We identified 6 studies with a total of 1,063 patients. Studies grouped surgical cases into "early" versus "late" in a surgeon's experience, with 30 cases being the most common cutoff used. Most of these studies used descriptive statistics and operative time and complication rates as measures of competence. Five of 6 studies showed improvement in these measures between early and late experience, but only one study proposed a bona fide curve. CONCLUSIONS This review shows that when 30 cases was used as the cutoff point to differentiate between early and late cases in a surgeon's experience, there were significant reductions in operative time and complication rates. However, there was insufficient evidence to quantify the learning curve and validate 30, or any number of cases, as the point at which the learning curve plateaus. As a result, this number should be interpreted with caution. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.
