Abstract
BACKGROUND Arthroscopic labral repair has been shown to result in favorable short- and midterm outcomes; however, the durability of outcomes specifically in older patients remains underreported. PURPOSE To (1) report prospectively collected hip preservation rates and patient-reported outcome measures (PROMs) at a minimum 10-year follow-up in patients aged ≥40 years after primary hip arthroscopy with labral repair and (2) perform a matched analysis comparing patients aged ≥40 years with patients aged <40 years. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed on all patients who underwent primary hip arthroscopy between February 2008 and December 2011. Patients aged ≥40 years who underwent labral repair were included. Preoperative and minimum 10-year follow-up scores were collected for multiple PROMs. Propensity score matching was utilized to compare these patients with a cohort of patients <40 years. RESULTS Of the 113 hips eligible, 91 hips (80.5%) on 85 patients (6 bilateral) had a minimum 10-year follow-up. There were 58 women (68%) and 27 men (32%) with a mean age and body mass index of 47.8 years and 25.8, respectively. The hip preservation rate for patients aged ≥40 years was 78%, with 20 patients requiring arthroplasty during the study period. There was significant improvement in all PROMs from baseline to minimum 10-year follow-up with high rates of achieving the minimal clinically important difference and Patient Acceptable Symptom State clinical outcome thresholds. In total, 69 patients aged ≥40 years were propensity matched to 107 patients <40 years. Patients ≥40 tended to have a lower hip preservation rate (81.2% vs 91.6%; P = .06), while patients in the younger cohort had significantly higher rates of secondary hip arthroscopy (14% vs 3%; P = .02). Improvement in PROMs was comparable between the groups. CONCLUSION Patients ≥40 years who underwent primary hip arthroscopy with labral repair demonstrated a hip preservation rate of 78%, significant and durable improvement in PROMs, and high rates of satisfaction at a minimum 10-year follow-up. Matched analysis with patients <40 years revealed comparable improvement in patient-reported outcomes between the 2 groups, with a tendency to a higher level of arthroplasty in patients ≥40 years.

Abstract
PURPOSE To report minimum 5-year follow-up patient-reported outcome measurement (PROM) scores and return-to-dance rates in dancers who underwent primary hip arthroscopy and to identify predictors of secondary surgical procedures. METHODS Prospectively collected data from patients who underwent hip arthroscopy between May 2010 and June 2016 were retrospectively reviewed. Patients were included if they participated in dance at any level 1 year prior to surgery and had preoperative and minimum 5-year follow-up scores consisting of the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale pain score. The exclusion criteria were previous hip conditions, previous ipsilateral hip surgery, Tönnis grade greater than 1, or lateral center-edge angle less than 18°. The minimal clinically important difference (MCID) was reported. Dancers who discontinued dance for reasons other than pain in the operative hip were excluded from the return-to-dance analysis. A logistic regression model was used to identify predictors of secondary surgical procedures. RESULTS Fifty-one hips (48 female dancers) were included. The average age and average follow-up period were 29.8 ± 17.2 years and 79.1 ± 23.2 months, respectively. Improvement in all PROM scores (P < .001) was reported. Achievement rates of the MCID for the modified Harris Hip Score, Nonarthritic Hip Score, and visual analog scale pain score were 83.3%, 85.7%, and 85.7%, respectively. Revision hip arthroscopy was performed in 5 dancers (9.8%). Conversion to total hip arthroplasty was performed in 4 dancers (7.8%). The return-to-dance rate was 78.6%, with 57.6% returning to the preinjury performance level or a higher level. Higher femoral head Outerbridge grade was identified as a predictor of secondary surgical procedures (P = .045; odds ratio, 6.752 [95% confidence interval, 1.043-43.688]). CONCLUSIONS After primary hip arthroscopy, dancers experienced significant improvement in all PROM scores collected and achieved the MCID at a high rate at minimum 5-year follow-up. The return-to-dance rate in dancers who did not discontinue dance because of lifestyle transitions was 78.6%, with 57.6% returning to the preinjury performance level or a higher level. Higher femoral head Outerbridge grade was found to be a predictor of secondary surgical procedures. LEVEL OF EVIDENCE Level IV, case series.

Abstract
PURPOSE OF REVIEW Arthroscopic treatment of femoroacetabular impingement syndrome (FAIS) continues to rise in incidence, and thus there is an increased focus on factors that predict patient outcomes. The factors that impact the outcomes of arthroscopic FAIS treatment are complex. The purpose of this review is to outline the current literature concerning predictors of patient outcomes for arthroscopic treatment of FAIS. RECENT FINDINGS Multiple studies have shown that various patient demographics, joint parameters, and surgical techniques are all correlated with postoperative outcomes after arthroscopic FAIS surgery, as measured by both validated patient-reported outcome (PRO) scores and rates of revision surgery including hip arthroplasty. To accurately predict patient outcomes for arthroscopic FAIS surgery, consideration should be directed toward preoperative patient-specific factors and intraoperative technical factors. The future of accurately selecting patient predictors for outcomes will only improve with increased data, improved techniques, and technological advancement.

Abstract
BACKGROUND Previous studies evaluating the outcomes of hip arthroscopy for patients with global acetabular overcoverage and focal superolateral acetabular overcoverage suffer from short-term follow-up and inconsistent radiographic criteria when defining these subpopulations of patients with femoroacetabular impingement syndrome (FAIS). PURPOSE To evaluate the intermediate-term postoperative outcomes for patients with FAIS in the setting of global acetabular overcoverage, lateral acetabular overcoverage, and normal acetabular coverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients undergoing hip arthroscopy for FAIS were enrolled in a prospective cohort study, and those with a minimum follow-up of 5 years were included in this analysis. Patients were grouped based on type of acetabular coverage: global overcoverage (lateral center-edge angle [LCEA] ≥40°, with coxa profunda), lateral overcoverage (LCEA ≥40°, without coxa profunda), and no overcoverage (LCEA <40°). Functional outcomes (modified Harris Hip Score and Nonarthritic Hip Score) and failure of primary hip arthroscopy were compared between groups. RESULTS In total, 94 patients (mean age, 41.9 ± 14.2 years) were included with a mean follow-up duration of 6.1 ± 0.9 years. Of these patients, 40.4% had no acetabular overcoverage, 36.2% had lateral overcoverage, and 23.4% had global overcoverage. There was no difference between groups with respect to percentage of patients who underwent reoperation for either revision arthroscopy or conversion to total hip arthroplasty (28.9% for the normal acetabular coverage group, 29.4% for the lateral overcoverage group, and 31.8% for the global overcoverage group; P = .971). Among patients for whom primary hip arthroscopy did not fail, there was no difference in 5-year functional outcomes between groups. Postoperative LCEA >40° (β = -13.3; 95% CI, -24.1 to -2.6; P = .016), female sex (β = -14.5; 95% CI, -22.7 to -6.2; P = .001), and higher body mass index (β = -1.9; 95% CI, -2.8 to -1.0; P < .001) were associated with worse intermediate-term hip function in terms of modified Harris Hip Score. CONCLUSION There was no difference in functional outcomes or rate of reoperation at a minimum of 5 years postoperatively between those with global acetabular overcoverage, those with regional lateral overcoverage, and those with normal acetabular coverage. Provided that an appropriate acetabuloplasty is performed, there is no evidence to suggest that global acetabular overcoverage portends a worse prognosis than other FAIS subtypes.

Abstract
PURPOSE Femoroacetabular impingement (FAI) is a known risk factor for hip osteoarthritis. The gold standard for diagnostics is X-ray and MRI. The accuracy of hip joint alpha angle measurements obtained using sonography is equal to measurements in MRI for patients with cam impingement of the hip joint. MATERIALS AND METHODS Patients with hip pain and MRI and sonography were evaluated between January 2015 and December 2019 in a single center. Musculoskeletal sonography was performed according to the DEGUM guidelines by ultrasound-certified specialists. Measurements were repeated three times by two independent investigators. RESULTS 285 patients were screened, and 110 patients (49 females, 61 males) met the inclusion criteria. The mean age at time of investigation of 54 left and 56 right hip joints was 54.2 years. 1320 measurements were performed. The mean alpha angle was 50.7° in MRI and 50.4° in sonography with a mean difference of 0.28° (p>0.05). CONCLUSION Determining hip alpha angle using sonography is a safe and reproducible method. No statistically significant differences between results in MRI and sonography could be seen. Although this is a retrospective, single-center study including only Caucasian mid-Europeans and with the known limitations of ultrasound imaging, it nevertheless shows that sonography can be used as a simple, cheap, and fast technique to assess the hip alpha angle without losing diagnostic quality.

Abstract
PURPOSE (1) To report minimum 5-year patient-reported outcomes (PROs) and return to sport (RTS) rates in high-level athletes with borderline hip dysplasia (BHD) following primary hip arthroscopy for labral pathology and femoroacetabular impingement syndrome and (2) to compare results to a propensity-matched control group of athletes with normal acetabular coverage. METHODS Data were reviewed for surgeries performed between February 2009 and February 2016. Patients were eligible if they underwent primary hip arthroscopy in the setting of BHD (lateral center-edge angle [LCEA] 18-25°) and competed in professional, collegiate, or high school sports. Inclusion criteria were preoperative and minimum 5-year follow-up scores for the modified Harris Hip Score (mHHS), Non-Arthritis Hip Score, Hip Outcome Score-Sport Specific Subscale (HOS-SSS), and visual analog scale for pain. Rates of achieving the minimal clinically importance difference (MCID), patient acceptable symptomatic state (PASS), and maximum outcome improvement satisfaction threshold (MOIST) were recorded in addition to RTS. BHD athletes were matched by age at the time of surgery, sex, body mass index, Tönnis grade, follow-up time, sport type, and competition level to a control group of 58 athletes with normal acetabular coverage (LCEA 25°-40°) for comparison. RESULTS A total of 34 BHD athletes were included with a mean follow-up of 73.6 ± 10.7 months. BHD athletes showed significant improvements in all PROs, demonstrated high RTS rates (90.0%), and achieved PASS/MCID/MOIST for mHHS (MCID: 80.0%, PASS: 93.3%, MOIST: 80.0%) and HOS-SSS (MCID: 76.7%, PASS: 73.3%) at high rates. When compared to a propensity-matched group with normal acetabular coverage, BHD athletes demonstrated similar postoperative PROs, rates of achieving psychometric thresholds, and RTS rates (P > .05). Additionally, by the latest follow-up, no athlete in either group required conversion to total hip arthroplasty. CONCLUSIONS High-level athletes with BHD undergoing primary hip arthroscopy for labral pathology and femoroacetabular impingement syndrome may expect favorable midterm outcomes and high RTS rates. These results were comparable to a control group of athletes with normal coverage. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
PURPOSE To assess whether preoperative joint space measures would be predictive of survivorship in patients undergoing hip arthroscopy (HA) for femoroacetabular impingement (FAI). METHODS Data on consecutive patients who underwent hip arthroscopy between February 2008 and February 2018 were retrospectively reviewed. To be eligible for final analysis, patients were required to have preoperative radiographs for joint space measurements and data indicating conversion to a total hip arthroplasty (THA), hip resurfacing, or neither; at a minimum of 2 years after primary hip arthroscopy. Survivorship following HA was defined as remaining conversion free and served as the primary outcome. A multivariate logistic regression analysis and receiver operator curve (ROC) were used to evaluate the correlation between joint space measurements and survivorship following HA. RESULTS A total of 1,885 primary arthroscopy cases were included in this study. The multivariate regression analysis found preoperative lateral-to-medial joint space ratio (L/M ratio) to be the strongest predictive factor of survivorship after primary hip arthroscopy (OR = 2.084, CI95% = 1.239-3.503; P = .006). The ROC curve for the model demonstrated acceptable discrimination with an area under the curve (AUC) of 0.792. Patients with an L/M ratio ≥0.75 had a survivorship rate of 91.7% compared to a rate of 75% for patients with an L/M ratio <0.75 (OR: 3.68). CONCLUSIONS This study found that, of the factors evaluated in this study, the most significant factor in predicting survivorship at 2 years after undergoing primary hip arthroscopy was a larger lateral-to-medial joint space ratio. This may suggest an initiation of primary arthritis at the edge-loading area of the lateral acetabulum. LEVEL OF EVIDENCE: III, retrospective comparative observation study.

Abstract
PURPOSE To report minimum 10-year follow-up survivorship, defined as non-conversion to total hip arthroplasty (THA), and patient-reported outcome scores (PROS) after primary hip arthroscopy with acetabular microfracture in the setting of femoroacetabular impingement syndrome (FAIS) and acetabular chondral lesions, respectively. METHODS Data were prospectively collected and retrospectively analyzed on all patients who underwent a primary hip arthroscopy and received an acetabular microfracture between June 2009 and January 2011. Patients with a minimum 10-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and the visual analog scale (VAS) for pain were included. If available, the minimum 10-year follow-up for the Hip Outcome Score-Sport-Specific Subscale was reported. The demographics, intraoperative findings, surgical procedures, PROS, rate of achieving the minimal clinical important difference (MCID), and secondary surgeries were analyzed and reported. RESULTS Twenty-two hips (20 patients) were included in the study, and the mean follow-up time was 124.5 ± 2.2 months. There were 17 hips (77.3%) from males and 5 hips (22.7%) from females. The average patient age at the time of surgery was 42.3 years ± 9.6. All patients on average experienced statistically significant improvement (P < .05) between preoperative and minimum 10-year follow-up scores for all PROs. In total, 77.3% of the patients did not require conversion to THA. Additionally, 83.3% of the patients achieved the MCID for the mHHS, NAHS, and VAS for pain. CONCLUSION At a minimum 10-year follow-up, survivorship of 77.3% was reported for patients who underwent primary hip arthroscopy with acetabular microfracture for the treatment of FAIS and focal/full-thickness acetabular cartilage lesions. Further, in the patients that did not require THA conversion, significant improvement in all PROS was demonstrated. LEVEL OF EVIDENCE IV, case-series study.

Abstract
BACKGROUND The minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), substantial clinical benefit (SCB), and maximum outcome improvement (MOI) satisfaction threshold for the Hip Outcome Score Sport-Specific Subscale (HOS-SSS) have not been established in athletes undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). PURPOSE To determine threshold MCID, PASS, SCB, and MOI satisfaction threshold values for the HOS-SSS in athletes undergoing hip arthroscopy for FAIS at minimum 2-year follow-up. STUDY DESIGN Cohort study (Diagnosis); Level of evidence, 3. METHODS Anchor questions were administered to recreational, organized amateur, high school, college, and professional athletes who underwent primary hip arthroscopy for FAIS between May 2015 and March 2019. Patients were included if they were younger than 50 years, answered the anchor questions, and had preoperative and minimum 2-year follow-up for the HOS-SSS, modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and visual analog scale (VAS) for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia (lateral center-edge angle <18°), and previous ipsilateral hip surgery or conditions. Receiver operating characteristic (ROC) analysis was used to determine PASS, SCB, and MOI satisfaction for the HOS-SSS. Two distribution methods were used to calculate MCID for HOS-SSS. RESULTS A total of 225 athletes who underwent primary hip arthroscopy met the inclusion criteria. Of those athletes, 200 (88.9%) who had minimum 2-year follow-up and information regarding return to sport (RTS) were included. The cohort included 124 (62.0%) women and 76 (38.0%) men with a mean ± standard deviation age of 29.4 ± 10.4 years, body mass index of 25.6 ± 5.4, and follow-up of 29.5 ± 5.1 months. Athletes experienced significant improvements in HOS-SSS, mHHS, NAHS, and VAS from preoperative to latest postoperative follow-up (P < .001), and mean satisfaction was 8.2. The RTS rate was 83.7%. ROC analysis determined that the PASS, MOI satisfaction threshold, SCB absolute score, SCB change score, and MCID (baseline/change score methods) for the HOS-SSS were 77.0, 44.6%, 92.7, 30.6, and 10.6, respectively, with athletes achieving thresholds at high rates (80.0%, 80.5%, 45.0%, 54.0%, and 79.5%, respectively). CONCLUSION This study identified values for the HOS-SSS that can be used to define clinically meaningful outcomes in athletes after primary hip arthroscopy for FAIS. The PASS, MOI satisfaction threshold, SCB absolute score, SCB change score, and MCID for the HOS-SSS at minimum 2-year follow-up in athletes after primary hip arthroscopy were 77.0, 44.6%, 92.7, 30.6, and 10.6, respectively.

[PMID: 35809979 DOI: 10.1016/j.arthro.2022.01.041] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 01/19/2022] [Indexed: 02/02/2023]
Abstract
Complex statistical approaches are increasingly being used in the orthopaedic literature, and this is especially true in the field of sports medicine. Tools such as machine learning provide the opportunity to analyze certain research areas that would often require the complex assessment of large amounts of data. Generally, decision making is multifactorial and based upon experience, personal capabilities, available utilities, and literature. Given the difficulty associated with determining the optimal patient treatment, many studies have moved toward more complex statistical approaches to create algorithms that take large amounts of data and distill it into a formula that may guide surgeons to better patient outcomes while estimating and even optimizing costs. In the future, this clinical and economic information will play an important role in patient management.

Outcomes and Return-to-Sport Rates for Elite Athletes With Femoral Retroversion Undergoing Hip Arthroscopy: A Propensity-Matched Analysis With Minimum 2-Year Follow-up. Orthop J Sports Med 2022; 10:23259671221099840. [PMID: 35677020 PMCID: PMC9168879 DOI: 10.1177/23259671221099840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 03/22/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Return to sports (RTS) and patient-reported outcomes (PROs) for elite
athletes with femoral version abnormalities undergoing hip arthroscopy have
not been well established. Purposes: To (1) report minimum 2-year PROs and RTS rates in elite athletes with
femoral retroversion who underwent primary hip arthroscopy and (2) compare
clinical results to those of a propensity-matched control group of elite
athletes with normal femoral version who underwent primary hip
arthroscopy. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected and retrospectively reviewed for elite
(professional and collegiate) athletes with femoral version <5°, as
measured on magnetic resonance imaging scans, who underwent hip arthroscopy
for femoroacetabular impingement syndrome between March 2010 and April 2018.
Inclusion criteria were preoperative and minimum 2-year follow-up PROs for
the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome
Score–Sports Specific Subscale (HOS-SSS), and visual analog scale for pain.
Exclusion criteria were Tönnis grade >1, hip dysplasia, and previous
ipsilateral hip surgery or conditions. Rates of achieving the minimal
clinically important difference (MCID), Patient Acceptable Symptom State
(PASS), and maximum outcome improvement satisfaction threshold were recorded
in addition to RTS. Athletes with retroversion were propensity matched in a
1:2 ratio to elite athletes with normal femoral version (5°-20°) for
comparison. Results: A total of 33 elite athletes (33 hips) with femoral retroversion who
underwent hip arthroscopy met the inclusion criteria, and follow-up was
available for 30 hips in 30 athletes (90.9%) at an average of 36.1 ± 25.6
months. Elite athletes with femoral retroversion demonstrated significant
improvements in all recorded PROs, achieved the MCID and PASS for the
HOS-SSS at high rates (86.7%), and returned to sports at a rate of 83.3%.
PROs, rates of achieving MCID and PASS for the HOS-SSS, and RTS rates were
similar between the study and propensity-matched control group. Conclusion: Elite athletes with femoral retroversion undergoing primary hip arthroscopy
demonstrated favorable PROs and high RTS rates at a minimum 2-year
follow-up. These results were comparable with those of a propensity-matched
control group of elite athletes with normal femoral version.

Abstract
Background: There is a paucity of literature comparing sex-based outcome differences in
athletes after primary hip arthroscopy with labral reconstruction for
femoroacetabular impingement syndrome (FAIS) and irreparable labral
tears. Purpose: To report sex-based differences in clinical characteristics, patient-reported
outcome (PRO) scores, and return-to-sports (RTS) rates in athlete who
underwent primary hip arthroscopy with labral reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: Data were reviewed for recreational, organized amateur, high school,
collegiate, and professional athletes who underwent primary hip arthroscopy
with labral reconstruction for FAIS and irreparable labral tears between
July 2014 and May 2019. Inclusion criteria included preoperative and minimum
2-year postoperative PRO scores (modified Harris Hip Score, Non-Arthritic
Hip Score, Hip Outcome Score–Sports Specific Subscale, International Hip
Outcome Tool [iHOT-12], and visual analog scale [VAS] for pain). Exclusion
criteria were Tönnis grade >1, hip dysplasia (lateral center-edge angle,
<18°), or prior ipsilateral hip surgery/conditions. Patients were divided
into groups by sex and were propensity-matched in a 1:1 ratio by age, body
mass index, graft type, labral tear size, and sports level. Results: A total of 101 hips were eligible, and 94 hips (93.1%) had a minimum 2-year
follow-up. Twenty-nine female athlete hips were propensity-matched to 29
male athlete hips. Female athletes underwent higher rates of capsular repair
(79.3% vs 24.1% for men; P < .001) and lower rates of
acetabular microfracture (0.0% vs 20.7% for men; P = .024).
Both female and male athletes experienced significant improvement on all PRO
scores (P < .001 for all), high RTS rates (women, 84% vs
men, 80.8%), and high rates of achieving the minimal clinically important
difference for the iHOT-12 and VAS pain (women, 88.5% vs men, 71.4% for
both) and achieving the patient acceptable symptom state for the iHOT-12
(women, 88.5% vs men, 71.4%), with no significant difference between the
sexes. Conclusion: Despite different clinical characteristics and surgical procedures, both
female and male athletes undergoing primary hip arthroscopy with labral
reconstruction had significant improvements in all PROs at the minimum
2-year follow-up, high RTS rates, and similar rates of achieving the minimal
clinically important difference and patient acceptable symptom state.

Arthroscopy 2022; 38:1890-1899. [PMID: 34920010 DOI: 10.1016/j.arthro.2021.11.048] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 11/17/2021] [Accepted: 11/30/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To report minimum 2-year patient-reported outcome measures (PROMs) following primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and painful external snapping hip (ESH) treatment and ESH resolution, and to compare these PROMs to a benchmark FAIS propensity-matched control group without ESH. METHODS Data were prospectively collected and retrospectively reviewed between November 2009 and April 2018. Patients were eligible if they were preoperatively diagnosed with FAIS and painful ESH and received primary hip arthroscopy to address these pathologies. ESH was treated with gluteus maximus and iliotibial band releases. Inclusion criteria were baseline and minimum two-year follow-up scores for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale for pain. Exclusion criteria were Tönnis grade >1 and previous hip conditions. A secondary subanalysis was performed to benchmark these outcomes to a FAIS propensity-matched control group without ESH, according to age, sex, body mass index (BMI), Tönnis grade, and preoperative lateral center-edge and α-angles using a 1:3 ratio. The minimal clinically important difference (MCID) and the maximum outcome improvement (MOI) rates were reported. RESULTS Twenty-two hips (21 patients) were included. The mean age, BMI, and follow-up were 31.3 years ± 14.0, 26 kg/m2 ± 5.0, and 31.4 months ± 4.4, respectively, with 68.2% being female. ESH was resolved in 100% of patients. Significant improvement for all PROMs at a minimum two-year (P < .001) was reported. The minimum two-year PROMs and the rate of achieving the MCID and MOI threshold were comparable to the control group. CONCLUSION Following primary hip arthroscopy for FAIS and painful ESH, patients demonstrated significant improvement in all PROMs, and the rate of resolution of ESH was 100% at minimum two-year follow-up: with gluteus maximus and iliotibial band releases. Functional outcomes and rates of MCID and MOI achievement were comparable to a FAIS propensity-matched benchmark control group without ESH. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Background: There is limited literature evaluating patient-reported outcomes (PROs) in
cigarette smokers undergoing hip arthroscopy for femoroacetabular
impingement syndrome (FAIS) at midterm follow-up. Purpose: (1) To report minimum 5-year PROs for cigarette-smoking patients who
underwent primary hip arthroscopy for FAIS and (2) to compare these results
with a propensity-matched control group of never-smoking patients. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected for all patients who underwent primary hip arthroscopy
for FAIS between June 2009 and March 2016. Patients were eligible if they
indicated that they smoked cigarettes within 1 month of surgery and had
minimum 5-year postoperative outcomes for the modified Harris Hip Score,
Nonarthritic Hip Score, Hip Outcome Score–Sport Specific Subscale (HOS-SSS),
and International Hip Outcome Tool–12 (iHOT-12). The percentages of patients
achieving the Patient Acceptable Symptom State (PASS) and maximum outcome
improvement satisfaction threshold were recorded. The study group was then
propensity matched in a 1:2 ratio to patients who had never smoked for
comparison. Results: Included were 35 patients (35 hips) with a mean age of 39.4 ± 13.0 years and
mean follow-up of 64.6 ± 4.1 months. These patients demonstrated significant
improvement from preoperatively to a minimum 5-year follow-up for all
recorded PROs (P < .05). When compared with 70 control
patients (70 hips), smoking patients demonstrated significantly worse
preoperative scores for all PROs (P < .05). Study
patients also demonstrated worse minimum 5-year scores for all recorded PROs
compared with control patients, which did not reach statistical significance
but trended toward significance for HOS-SSS (70.4 vs 81.9;
P = .076) and iHOT-12 (74.7 vs 82.2; P
= .122). Smoking patients also trended toward lower rates of achieving PASS
for the iHOT-12 compared with never-smoking patients (50.0% vs 68.2%;
P = .120). Conclusion: Patients who smoked cigarettes and underwent primary hip arthroscopy for FAIS
demonstrated significant improvement in PROs at a minimum 5-year follow-up.
When compared with a propensity-matched control group of never-smokers, they
trended toward lower postoperative HOS-SSS and iHOT-12 scores and lower
rates of achieving PASS on the iHOT-12.

Abstract
Background: There is a paucity of literature evaluating the effect of cigarette smoking
on outcomes in patients undergoing hip arthroscopy and labral
reconstruction. Purpose: (1) To report minimum 2-year patient-reported outcome (PRO) scores for
patients who smoke cigarettes and underwent primary hip arthroscopic labral
reconstruction and (2) to compare these results with those of a
propensity-matched control group of patients who have never smoked. Study Design: Cohort study; Level of evidence, 3. Methods: Data were collected for all patients who underwent primary hip arthroscopy
for labral reconstruction between January 2011 and January 2019. Patients
were eligible for the study if they indicated that they smoked cigarettes
within 1 month of surgery and had minimum 2-year postoperative outcome
scores for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score
(NAHS), and the visual analog scale (VAS) for pain. The percentage of
patients achieving the minimal clinically important difference (MCID) and
patient-acceptable symptom state (PASS) was recorded. Rates of revision
surgery were also documented. These patients were then propensity matched in
a 1:3 ratio to patients who had never smoked (controls) for comparison. Results: A total of 20 patients (20 hips) were included with a mean follow-up of 39.9
± 13.0 months and mean age of 41.4 ± 10.4 years. These patients demonstrated
significant improvement from preoperatively to the minimum 2-year follow-up
for mHHS, NAHS, and VAS (P < .05). They also achieved
MCID for mHHS and VAS at acceptable rates, 70% for both. When outcomes were
compared with those of 60 control patients (60 hips), patients who smoke
demonstrated lower preoperative PRO scores but similar minimum 2-year
postoperative PRO scores for mHHS and NAHS. Patients who smoke demonstrated
lower rates of achieving PASS for mHHS (55% vs 75%) and NAHS (40% vs 61.7%)
compared with controls; however, these findings were not statistically
significant. Rates of secondary surgery were statistically significantly
higher in the smoking group compared with controls (25% vs 5%;
P = .031). Survivorship for the smoking patients was
80% and 98.3% for the control group. At the two-year mark survivorship was
90% for the smoking group and 100% for the control group (P
= .06) Conclusion: While smokers can still derive significant improvement from hip arthroscopy,
their ultimate functional outcome and rate of secondary surgeries are
inferior to those of nonsmokers. As smoking is a significant and modifiable
risk factor, we should continue to counsel smokers on smoking cessation
prior to and after surgery

Multicenter Outcomes After Primary Hip Arthroscopy: A Comparative Analysis of Two-Year Outcomes After Labral Repair, Segmental Labral Reconstruction, or Circumferential Labral Reconstruction. Arthroscopy 2022; 38:352-361. [PMID: 34052367 DOI: 10.1016/j.arthro.2021.05.013] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Revised: 05/04/2021] [Accepted: 05/12/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE (1) To report minimum 2-year follow-up patient-reported outcome measures in patients undergoing labral repair (LR), segmental labral reconstruction (SLR), or circumferential labral reconstruction (CLR) in the primary setting; and (2) to compare minimum 2-year follow-up patient-reported outcome measures among these groups. METHODS A retrospective review of a prospectively maintained multicenter database of patients undergoing hip arthroscopy was performed. Inclusion criteria were patients undergoing hip arthroscopy for treatment of labral tear and femoroacetabular impingement syndrome between January 2014 and October 2017, and completion of minimum 2-year postoperative outcome scores. Exclusion criteria were patients undergoing revision hip surgery, labral treatment limited to debridement, lateral center-edge angle <20°, osteoarthritis (Tönnis grade > 1), slipped capital femoral epiphysis, workers compensation status, and patients undergoing concomitant gluteus medius and/or minimus repair. Labral reconstruction patients were matched (1:3) with labral repair patients on age, sex, and body mass index. The labral reconstruction group was further stratified into SLR, and CLR groups. Patient demographic characteristics and clinical outcomes including Hip Outcome Score - Activities of Daily Living, Hip Outcome Score - Sport Subscale, modified Harris Hip Score, international Hip Outcome Tool, and visual analog scale for pain were analyzed, as well as achievement of the minimal clinical improvement difference (MCID). A P-value less than .05 indicated statistical significance. RESULTS A total of 416 patients were included (LR, n = 312; SLR, n = 53; CLR, n = 51). The age, body mass index, and sex of the matched cohort were 42.3 ± 11.2 years, 24.7 ± 3.7, and 55.0% female. At a minimum of 2-year after hip arthroscopic surgery, no differences were found in preoperative, postoperative, or the delta visual analog scale for pain, modified Harris Hip Score, Hip Outcome Score - Activities of Daily Living, Hip Outcome Score - Sport Subscale, or international Hip Outcome Tool. Subsequently, the proportion of patients achieving the MCID and the PASS at latest follow-up were analyzed. This analysis revealed that no significant differences in the rate of MCID or PASS achievement for any outcome measure existed based on labral treatment. CONCLUSIONS In this multicenter study on labral treatment in the primary setting, patients undergoing LR, SLR, and CLR demonstrated no difference in preoperative or postoperative scores, nor the proportion of patients achieving clinically significant outcome improvement. LEVEL OF EVIDENCE III; therapeutic outcome study with controls.

Abstract
BACKGROUND Sex differences are frequently encountered when diagnosing orthopaedic problems. Current literature suggests specific sex differences, such as a higher prevalence of cam-type femoroacetabular impingement syndrome in male patients and features of hip instability in female patients. PURPOSE To identify hip pathology patterns according to sex, alpha angle deformity, and generalized ligamentous laxity (GLL) in a nonarthritic patient population that underwent primary hip arthroscopy in the setting of femoroacetabular impingement syndrome and labral tears. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Patients who underwent primary hip arthroscopy between February 2008 and February 2017 were included and separated into male and female groups for initial analysis. Patients were excluded if they had Tönnis osteoarthritis grade >1, previous ipsilateral hip surgery, or previous hip conditions. The demographics, radiographic findings, intraoperative findings, and surgical procedures were then analyzed and compared. Subanalyses were performed for both groups. A threshold of 1 SD above the mean alpha angle in the male group was used to create 2 subgroups. For female patients, GLL based on a Beighton score ≥4 was used to divide the group. Intraoperative findings were compared for both subanalyses. RESULTS A total of 2701 hips met all inclusion and exclusion criteria. Of those, 994 hips were in the male group and 1707 in the female group. The mean ± SD age was 36.6 ± 13.8 and 37.1 ± 15.0 years for the male and female groups, respectively(P = .6288). The average body mass index was significantly higher in the male group (P < .0001). GLL was more common in women (38.6%) than men (13.6%) (P < .001). The male group had a higher proportion of acetabular Outerbridge grade 3 (21.8%) and 4 (19.2%) lesions when compared with the female group (9.3% and 6.3%, respectively) (P < .0001). Men in the subgroup with an alpha angle ≥78° reported higher rates of acetabular Outerbridge grade 4 damage than men with an alpha angle <78° (P < .001). Mean lateral center-edge angle was lower in the female subgroup with Beighton score ≥4 vs <4 (23.7°± 4.2° vs 31.3°± 5.8°; P < .0001). CONCLUSION In this analysis of a large cohort of patients who underwent hip arthroscopy, 2 patterns of hip pathologies were related to sex. On average, male patients had larger alpha angles and increased acetabular chondral damage when compared with their female counterparts. Furthermore, a larger cam-type anatomy was associated with more severe acetabular chondral damage in men. In the female group, the incidence of features of hip instability such as GLL were significantly higher than in the male group.

Abstract
BACKGROUND Patient-reported outcomes (PROs) and return to sports (RTS) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) have not been established in elite athletes with coexisting low back pain (LBP). PURPOSE (1) To report minimum 2-year PROs and RTS rates after primary hip arthroscopy for FAIS in elite athletes with coexisting LBP and (2) to compare clinical results with a propensity-matched control group of elite athletes without back pain. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were reviewed for elite athletes (college and professional) who underwent hip arthroscopy for FAIS and had coexisting LBP between October 2009 and October 2018. Inclusion criteria were preoperative and minimum 2-year follow-up for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia (lateral center-edge angle <18°), and previous ipsilateral hip or spine surgery or conditions. Rates of achieving the minimal clinically importance difference (MCID), patient acceptable symptomatic state (PASS), and maximum outcome improvement satisfaction threshold were recorded in addition to RTS. For the subanalysis, the elite athlete study group was propensity matched to an elite athlete control group without back pain. RESULTS A total of 48 elite athletes with LBP who underwent primary hip arthroscopy met inclusion criteria, and follow-up was available for 42 (87.5%) at 53.2 ± 31.6 months (mean ± SD). Elite athletes with coexisting LBP demonstrated significant improvements in all recorded PROs and achieved the MCID and PASS for the HOS-SSS at rates of 82.5% and 67.5%, respectively. They also returned to sports at a high rate (75.8%), and 79% of them did not report LBP postoperatively. PROs, rates of achieving the MCID and PASS for the HOS-SSS, and RTS rates were similar between the study group and propensity-matched control group. CONCLUSION Elite athletes with coexisting LBP who undergo primary hip arthroscopy for FAIS may expect favorable PROs, rates of achieving the MCID and PASS for the HOS-SSS, and RTS rates at minimum 2-year follow-up. These results were comparable to those of a propensity-matched control group of elite athletes without back pain. In athletes with hip-spine syndrome, successful treatment of their hip pathology may help resolve their back pain.

Abstract
BACKGROUND Previous literature has suggested that primary acetabular labral reconstruction leads to lower secondary surgery rates than does labral repair for patients aged ≥40 years. PURPOSE To report minimum 2-year patient-reported outcome (PRO) scores, survivorship, and secondary surgeries in patients aged ≥40 years who underwent primary hip arthroscopy with labral reconstruction compared with a propensity-matched primary labral repair group. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for patients who underwent a primary hip arthroscopy for femoroacetabular impingement syndrome between January 2014 and June 2018. Patients aged ≥40 years who underwent a labral reconstruction or a labral repair and had preoperative and minimum 2-year PROs for the modified Harris Hip Score, Nonarthritic Hip Score, and visual analog scale (VAS) for pain were included. Patients with previous ipsilateral hip conditions and surgery, Tönnis grade >1, hip dysplasia, or workers' compensation status were excluded. Patients in the reconstruction group were propensity matched 1:2 to patients in the repair group based on age, sex, and body mass index. Secondary surgeries and achievement of the minimal clinically important difference (MCID), patient acceptable symptom state (PASS), and maximum outcome improvement (MOI) were recorded. RESULTS A total of 53 and 106 hips were included in the labral reconstruction and repair groups, respectively. The average follow-up time was 37.6 months. The average ages for the reconstruction and repair groups were 48.01 ± 5.4 years and 48.61 ± 6.0 years, respectively. Both groups achieved significant improvements in all PROs at a minimum of 2 years, with similar achievements of MCID, PASS, and MOI, and comparable secondary surgery rates. CONCLUSION Patients aged ≥40 years who received primary labral repair and primary labral reconstruction achieved similar significant improvements in all PROs, VAS pain, and patient satisfaction at the minimum 2-year follow-up, with comparable rates of secondary surgeries and achieving MCID, PASS, and MOI. Based on these findings, labral repair remains the gold standard treatment for viable labrum in this population group, while reconstruction is a useful alternative for irreparable labrum.

Abstract
BACKGROUND Return to sports (RTS) and patient-reported outcomes (PROs) for high-level athletes after bilateral hip arthroscopy have not been well established. PURPOSE (1) To report minimum 2-year PROs and RTS rates in high-level athletes who underwent staged bilateral primary hip arthroscopies and (2) to compare clinical results against a propensity-matched control group of high-level athletes who underwent unilateral primary hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for high-level athletes (professional, college, or high school) who underwent staged bilateral hip arthroscopy for femoroacetabular impingement syndrome between September 2009 and October 2018. Inclusion criteria were preoperative and minimum 2-year follow-up for modified Harris Hip Score, Non-arthritic Hip Score, Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia (lateral center-edge angle <18°), and previous ipsilateral hip surgery/conditions. Rates of achieving the minimal clinically important difference (MCID), patient acceptable symptomatic state (PASS), and maximum outcome improvement satisfaction threshold were recorded in addition to RTS. These athletes were then propensity matched in a 1:3 ratio to high-level athletes who underwent unilateral arthroscopy for comparison. Outcomes were compared among the first hip of the study group, the second hip of the study group, and the control group. RESULTS A total of 74 high-level athletes who underwent bilateral hip arthroscopy met the inclusion criteria, and follow-up was available for 68 (91.9%) at 58.9 ± 24.5 months (mean ± SD). Athletes undergoing bilateral hip arthroscopy returned to sports at a high rate (81.7%), demonstrated significant improvements in all recorded PROs, and achieved the MCID and PASS for the HOS-SSS at rates of 80.9% and 64.7%, respectively. PROs, RTS rate, and rates of achieving the MCID and PASS for the HOS-SSS were similar when the bilateral study group was compared with the unilateral control group (P > .05). CONCLUSION High-level athletes who undergo staged bilateral primary hip arthroscopy for femoroacetabular impingement syndrome may expect favorable PROs and RTS rates at minimum 2-year follow-up. These results were comparable with those of a propensity-matched control group of high-level athletes who underwent unilateral primary hip arthroscopy.

Abstract
BACKGROUND Femoroacetabular Impingement (FAI) is a common cause of hip pain in adolescent patients. Clinical exam and radiographic markers, such as α angle and lateral center edge angle (LCEA), are commonly used to aid in the diagnosis of this condition. The purpose of this study was to correlate preoperative α angle and LCEA with preoperative symptoms, intraoperative findings, and preoperative and postoperative patient reported outcomes (PROs) in the adolescent patient. METHODS A retrospective analysis of prospectively collected data was conducted for all patients who underwent operative intervention for FAI at an academic institution over an 11-year period. Preoperative imaging was obtained and measured for LCEA and α angle. PROs (modified Harris Hip Score, Hip Disability and Osteoarthritis Outcome Score, and UCLA score) were collected preoperatively, as well as 1, 2, and 5 years postoperatively. Operative intervention was either open surgical hip dislocation or arthroscopic, and intraoperative disease was graded using the Beck Classification system. Patients with minimum 1-year follow-up were included in statistical analysis. RESULTS There were 86 hips (64 female hips) included with an average age of 16.3 years (range, 10.4 to 20.5 y), with an average of 37 months of follow-up. There was no correlation between severity of preoperative symptoms or difference between pre and postoperative PROs for both α angle and LCEA. Overall, significant improvement was noted in modified Harris Hip Score, Hip Disability and Osteoarthritis Outcome Score, and UCLA Score (P<0.001 for each). Independent of preoperative symptoms, increased α angle correlated with more severe intraoperative labral disease (P<0.001), and longer length of labral tear (Corr 0.295, P<0.01). Femoral head and acetabular articular cartilage damage did not correlate with α angle or LCEA, nor did overall severity of disease. CONCLUSIONS In adolescent patients with FAI, increased α angle was found to significantly correlate with labral pathology, including increased length of tear and severity of disease, irrespective of preoperative symptoms or postoperative patient reported outcomes. LEVEL OF EVIDENCE Level III-retrospective.

Abstract
BACKGROUND Improvement in patient-reported outcomes (PROs) has been reported in the short term after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear in the setting of acetabular overcoverage. Yet, there is a paucity of information in the literature on midterm PROs. PURPOSE To (1) report minimum 5-year PROs in patients who underwent primary hip arthroscopy for FAIS and acetabular labral tears in the context of acetabular overcoverage and (2) compare outcomes with those of a propensity-matched control group without acetabular overcoverage. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively analyzed on all patients who underwent hip arthroscopy for FAIS and labral tears between February 2008 and November 2013. Inclusion criteria were lateral center-edge angle >40° and minimum 5-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and the Hip Outcome Score-Sports-Specific Subscale (HOS-SSS). Exclusion criteria were previous ipsilateral hip surgery or conditions, active workers' compensation claims, or lack of minimum 5-year outcomes. A 1:1 propensity-matched comparison was made between the study group and a control group without acetabular overcoverage (lateral center-edge angle, 25°-40°) based on age at surgery, sex, body mass index, Tönnis grade, laterality, and follow-up time. The minimal clinically important difference (MCID) was calculated for the mHHS, HOS-SSS, and NAHS. Secondary surgical procedures were recorded. RESULTS A total of 54 patients satisfied the inclusion criteria for the study group, of whom 45 (83.3%; 45 hips) had a minimum 5-year follow-up and were matched without differences in age at surgery, sex, body mass index, or follow-up time. The study and control groups demonstrated significant and comparable improvements for the mHHS (mean ± SD Δ, 24.06 ± 24.19 vs 26.33 ± 17.27; P = .625), NAHS (Δ, 31.22 ± 25.31 vs 27.15 ± 17.61; P = .399), and HOS-SSS (Δ, 33.16 ± 34.73 vs 34.75 ± 26.15; P = .557). The rates for achieving the MCID were similar for the study and control groups for the mHHS (76.7% vs 84.2%; P = .399), HOS-SSS (79.1% vs 75.8%; P = .731), and NAHS (81.4% vs 84.2%; P = .738). Need for revision surgery was similar (P = .748). A lower conversion rate to total hip arthroplasty was reported for the study than for the control group (2.2% vs 15.6%; P = .026). CONCLUSION In the context of FAIS, labral tears, and acetabular overcoverage, patients who underwent hip arthroscopy reported significant improvement in several PROs at minimum 5-year follow-up. Moreover, outcomes were comparable with those of a propensity-matched control group without acetabular overcoverage. Furthermore, the rate of achieving the MCID for the mHHS, HOS-SSS, and NAHS was similar between these groups.

Abstract
The function and importance of the acetabular labrum in hip biomechanics have been determined. A labral tear is one of the most common findings in the hip preservation field, commonly associated with femoroacetabular impingement (FAI) syndrome. It has been established that the restoration of labral anatomy and function are key factors to improve patient-reported outcome measurements (PROMs) and psychometric tools following arthroscopic hip arthroscopy in the context of FAI syndrome. Labral repair or refixation is currently the gold-standard surgical option when facing labral tears, with clinical mid to long-term data supporting its use. Labral selective debridement has proven to be a valid alternative in selective patients. Acetabular labral reconstruction has risen as an alternative to labral excision or resection when repair is not an option due to labral tissue deficiency. Restoring the labral sealing mechanism is the goal behind the acetabular labral reconstruction. It has been proven that labral reconstruction leads to superior PROMs when compared with resection. This review presents an analysis of the indications, techniques, and outcomes for arthroscopic acetabular labral reconstruction.

Abstract
BACKGROUND Labral tears are the most common abnormalities in patients undergoing hip arthroscopic surgery. Appropriate management is crucial, as it has been shown that better overall outcomes can be achieved with labral restoration. PURPOSE To report the patient-reported outcomes (PROs) at minimum 2-year follow-up of patients who underwent hip arthroscopic surgery for labral tear repair using the knotless controlled-tension anatomic technique in the setting of femoroacetabular impingement syndrome (FAIS). STUDY DESIGN Case series; Level of evidence, 4. METHODS Data were prospectively collected for patients who underwent hip arthroscopic surgery for FAIS for labral tear repair using the knotless controlled-tension anatomic technique. Patients were excluded if they had prior hip conditions, prior ipsilateral surgery, Tönnis grade >1, a lateral center-edge angle (LCEA) <25°, or workers' compensation claims. Preoperative and postoperative scores at minimum 2-year follow-up were recorded for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), and visual analog scale (VAS) for pain. The proportion of patients who achieved the minimal clinically important difference (MCID) or patient acceptable symptomatic state (PASS) for the mHHS, HOS-SSS, and iHOT-12 were also reported. RESULTS A total of 309 hips were included. The mean patient age was 36.2 years (range, 12.8-75.9 years). The mean preoperative LCEA and alpha angle were 31.9° and 57.1°, respectively. A significant improvement on the mHHS (62.6 ± 15.7 preoperatively vs 86.9 ± 16.2 at 2-year follow-up), NAHS (63.1 ± 16.7 vs 86.1 ± 16.7), and HOS-SSS (39.8 ± 22.0 vs 74.2 ± 27.3) was found (P < .001 for all). A significant decrease was shown for VAS scores (P < .001). Also, 78.6% and 82.2% of patients achieved the MCID and PASS for the mHHS, respectively; 60.8% and 69.9% of patients met the MCID and PASS for the HOS-SSS, respectively; and the MCID for the iHOT-12 was met by 77.3% of patients. CONCLUSION In the setting of FAIS and labral tears, patients who underwent hip arthroscopic surgery for labral tear repair using the knotless controlled-tension anatomic technique demonstrated significant improvement in several validated PRO measures, the VAS pain score, and patient satisfaction at a minimum 2 years of follow-up. Based on this evidence, labral tear repair using the knotless controlled-tension anatomic technique seems to be a safe option.
