Abstract
Background There is a paucity of aggregate data documenting mid- to long-term outcomes of patients after hip arthroscopy with labral reconstruction. Purpose To report mid- to long-term outcomes in patients after undergoing either primary or revision hip arthroscopy with labral reconstruction for the treatment of irreparable labral tears. Study Design Systematic review; Level of evidence, 4. Methods A systematic review of the PubMed, Cochrane, and Scopus databases in May 2022 was conducted with the following keywords: "hip arthroscopy,""labral reconstruction,""irreparable,""labrum,""reconstruction,""five-year,""midterm,""5 year,""long-term,""10 year," ten-year," and "femoroacetabular impingement" using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Midterm was defined as mean 5-year follow-up, and long-term was defined as mean 10-year or longer follow-up. For each included article, the demographic, radiographic, intraoperative, and surgical variables, as well as patient-reported outcomes (PROs), psychometric thresholds, and secondary surgeries were recorded. Forest plots were created for PROs that were reported in ≥3 studies; heterogeneity was assessed using I2 values. Results Out of 463 initial articles, 5 studies including 178 hips with primary and 41 hips with revision surgeries were included. One study had an average 5-year follow-up, three studies had a minimum 5-year follow-up and one study had a minimum 10-year follow-up. The most common indications for hip arthroscopy with labral reconstruction were irreparable labral tears. The most common PRO was the modified Harris Hip Score (mHHS), which was reported in all 5 studies. The mean preoperative mHHS ranged from 58.9 to 66, and the mean postoperative mHHS at minimum 5-year follow-up ranged from 80.2 to 89. The preoperative and postoperative mHHSs for the single long-term follow-up study were 60 and 82, respectively. All 5 studies demonstrated significant improvements in reported PROs. All 5 studies reported secondary surgery rates, with 1 study reporting rates at both 5- and 10-year follow-up. Conversion to total hip arthroplasty ranged from 0% to 27%, while overall secondary surgery rates ranged from 0% to 36%. Conclusion Findings demonstrated that patients undergoing primary and revision hip arthroscopy with labral reconstruction experienced favorable outcomes and high rates of clinical benefit and survivorship at mid- to long-term follow-up.

Hip arthroscopy with initial access to the peripheral compartment for femoroacetabular impingement: midterm results from a large-scale patient cohort. J Orthop Traumatol 2024; 25:29. [PMID: 38789896 PMCID: PMC11126547 DOI: 10.1186/s10195-024-00770-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 05/09/2024] [Indexed: 05/26/2024] Open
Abstract
BACKGROUND Hip arthroscopy with initial access to the peripheral compartment could reduce the risk of iatrogenic injury to the labrum and cartilage; furthermore, it avoids the need for large capsulotomies with separate portals for peripheral and central (intra-articular) arthroscopy. Clinical results of the peripheral-compartment-first technique remain sparse, in contrast to those of conventional hip arthroscopy starting in the intra-articular central compartment. The purpose of this study was to assess outcome of hip arthroscopy with the peripheral-compartment-first technique, including complication rates, revision rates and patient-reported outcome scores. MATERIALS AND METHODS This outcome study included 704 hips with femoroacetabular impingement. All arthroscopies were performed using the peripheral-compartment-first technique. A joint replacement registry and the institutional database were used to assess the revision and complication rates, while patient-reported outcome measures were used to assess functional outcomes and patient satisfaction. RESULTS In total, 704 hips (615 patients) were followed up for a mean of 6.2 years (range 1 to 9 years). The mean age of the patients was 32.1 ± 9.2 years. During the follow-up period, 26 of 704 (3.7%) hips underwent total hip arthroplasty (THA) after a mean of 1.8 ± 1.2 years, and 18 of the 704 (2.6%) hips required revision hip arthroscopy after a mean of 1.2 ± 2.1 years. 9.8% of the hips had an unsatisfactory patient-reported outcome at final follow-up. CONCLUSIONS The results for the peripheral-compartment-first technique were promising. We recommend a well-conducted randomized controlled clinical trial to guide future therapeutic recommendations regarding the most favorable hip arthroscopy technique. LEVEL OF EVIDENCE Level IV, therapeutic study. TRIAL REGISTRATION This study was registered at ClinicalTrials.gov (U.S. National Library of Medicine; ID: NCT05310240).

Abstract
Aims Hip arthroscopy (HA) has become the treatment of choice for femoroacetabular impingement (FAI). However, less favourable outcomes following arthroscopic surgery are expected in patients with severe chondral lesions. The aim of this study was to assess the outcomes of HA in patients with FAI and associated chondral lesions, classified according to the Outerbridge system. Methods A systematic search was performed on four databases. Studies which involved HA as the primary management of FAI and reported on chondral lesions as classified according to the Outerbridge classification were included. The study was registered on PROSPERO. Demographic data, patient-reported outcome measures (PROMs), complications, and rates of conversion to total hip arthroplasty (THA) were collected. Results A total of 24 studies were included with a total of 3,198 patients (3,233 hips). Patients had significantly less improvement in PROMs if they had Outerbridge grade III and IV lesions (p = 0.012). Compared with microfracture, autologous matrix-induced chondrogenesis (AMIC) resulted in significantly reduced rates of conversion to THA (p = 0.042) and of revision arthroscopy (p = 0.038). Chondral repair procedures in these patients also did not significantly reduce the rates of conversion to THA (p = 0.931), or of revision arthroscopy (p = 0.218). However, compared with microfracture, AMIC significantly reduced the rates of conversion to THA (p = 0.001) and of revision arthroscopy (p = 0.011) in these patients. Those with Outerbridge grade III and IV lesions also had significantly increased rates of conversion to THA (p = 0.029) and of revision arthroscopy (p = 0.023) if they had associated lesions of the acetabulum and femoral head. Those who underwent labral debridement had a significantly increased rate of conversion to THA compared with those who underwent labral repair (p = 0.015). Conclusion There is universal improvement in PROMs following HA in patients with FAI and associated chondral lesions. However, those with Outerbridge grade III and IV lesions had significantly less improvement in PROMs and a significantly increased rate of conversion to THA than those with Outerbridge grade I and II. This suggests that the outcome of HA in patients with FAI and severe articular cartilage damage may not be favourable.

Abstract
Many techniques have been described for reconstruction of the acetabular labrum, but the procedure is known to be technically rigorous leading to lengthy procedure times and traction times. Increasing efficiency of the procedure with respect to graft preparation and delivery remain areas for potential improvement. We describe a simplified procedure for arthroscopic segmental labral reconstruction using peroneus longus allograft and a single working portal to shuttle the graft into the joint via suture anchors placed at the terminal extents of the graft defect. This method allows for efficient preparation, placement and fixation of the graft that can be completed in under 15 minutes.

Abstract
BACKGROUND The aim of this study was to explore the tissue healing process and changes in articular cartilage following acetabular labral augmentation in a porcine model. METHODS The labrum was resected unilaterally from 10 o'clock to 1 o'clock on the capsular side in 36 pigs. Eighteen pigs underwent labral augmentation (AUG group) using autologous Achilles tendon. No additional procedures were performed in the remaining pigs (control group). The pigs were killed at 6, 12, or 24 weeks postoperatively for histological assessment and measurement of the inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α in synovial fluid. RESULTS All autografts were well placed in the labral defect in the AUG group, and good integration of the autograft with the remnant chondrolabral junction was observed at 24 weeks; only scar tissue was observed in the control group at 6, 12, and 24 weeks. Fibrochondrocytes were concentrated at the transition between the autograft and native labrum at early time points, and the cells within the autograft labrum were predominantly fibrochondrocytes at 24 weeks. Rough and irregular articular cartilage surfaces were observed in 3 of the 6 samples in the AUG group at 24 weeks; the others appeared smooth. Focal cartilage erosion (predominantly in the acetabulum) occurred in all samples in the control group at 12 and 24 weeks. The Mankin score at 24 weeks was significantly lower in the AUG group than in the control group (mean [95% confidence interval]: 2.33 [1.06 to 3.6] versus 9 [8.06 to 9.94], p < 0.001). Likewise, the concentrations of all cytokines (in pg/mL) were significantly lower in the AUG group than in the control group at 24 weeks (IL-6: 166.6 [155.22 to 177.94] versus 245.9 [242.66 to 249.14], p < 0.001; IL-1β: 122.1 [116.4 to 127.83] versus 282.9 [280.29 to 285.51], p < 0.001; and TNF-α: 56.22 [53.15 to 59.29] versus 135 [131.66 to 138.24], p < 0.001). CONCLUSIONS Autograft tendon used for labral augmentation was able to integrate well with the native labrum, which may help to preserve the articular cartilage. CLINICAL RELEVANCE Labral augmentation with autograft tendon may be a feasible option in cases of viable labral remnants.

Arthroscopy 2023:S0749-8063(23)00182-2. [PMID: 36828155 DOI: 10.1016/j.arthro.2023.02.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 02/02/2023] [Accepted: 02/07/2023] [Indexed: 02/26/2023]
Abstract
PURPOSE To systematically review and report the mid- to long-term patient reported outcomes (PROs) following hip labral reconstruction. METHODS A literature search of the Pubmed, Embase, and Cochrane Library databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting mid- to long-term PROs at minimum five year follow-up following arthroscopic hip labral reconstruction. A quality assessment was performed using the Methodological Index of Non-Randomized Studies (MINORS) grading system. Data collection included study characteristics, demographics, indications, radiographic metrics, perioperative findings, surgical technique, baseline and most recent PROs, and subsequent surgeries. RESULTS Four studies met inclusion criteria, with 182 hips (age range, 27.9 to 38.7 years) undergoing labral reconstruction in primary and revision hip surgery with minimum five year follow-up. There were three level III studies and one level IV study, with an average MINORS score of 16.6. All studies cited labral tissue characteristics as a factor for surgical indications, including the quality and/or size of the labrum. Three studies performed segmental labral reconstructions, while another study utilized a circumferential technique. Varying grafts were selected, including hamstring autograft/allograft, ligamentum teres autograft, iliotibial band autograft, and tensor fascia lata autograft. All studies demonstrated improved PROs from baseline to most recent follow-up, with four studies reporting modified Harris Hip Score (mHHS) values that increased from baseline (range, 58.9 to 66.8) to most recent follow-up (range, 80.1 to 86.3). After labral reconstruction, rates of revision arthroscopy ranged from 4.8% to 13.3% and conversion to total hip arthroplasty ranged from 1.6% to 27%. CONCLUSION Improved PROs were observed in all studies at minimum 5-year follow-up, suggesting that labral reconstruction can offer durable results beyond short-term follow-up. While surgical indications for all studies included labral tissue characteristics, differing graft selection and surgical techniques were utilized across studies, limiting the ability to determine an optimal treatment approach.

Treatment of Severe Pincer-Type Femoroacetabular Impingement With Arthroscopic Significant Acetabular Rim Correction and Circumferential Labral Reconstruction Improves Patient-Reported Outcome Measures. Arthroscopy 2023; 39:41-50. [PMID: 35724802 DOI: 10.1016/j.arthro.2022.05.014] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 05/27/2022] [Accepted: 05/27/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To validate an arthroscopic approach for performing significant acetabular rim correction and circumferential labral reconstruction required to treat severe pincer-type femoroacetabular impingement. METHODS Using a minimum of 2-year follow-up, data from 48 hips, including 47 patients (11 male, 36 female; mean age of 42 years) having undergone significant arthroscopic acetabuloplasty for severe pincer impingement (center edge angle >45°) with concomitant circumferential allograft labral reconstruction were analyzed to determine improvements in patient-reported outcomes and degree of radiographic correction. RESULTS Findings demonstrated a 98% success rate, including substantial improvements on all radiographic measurements and patient-reported outcomes. Minimal clinically important differences were met with extremely strong measures of effect. The mean center edge angle improved from 49° to 36° (MΔ = 13.96, P ≤ .001, standard deviation [SD] = 55.97, confidence interval [CI] 12.17- 15.62, d = 2.33) and the mean Tönnis angle improved from -6° to 0° (MΔ = 6.2, P ≤ .001, SD = 2.76 CI -7.1 to -5.39, d = 2.29). Modified Hip Harris Scores improved by a mean of 34.45 points (P ≤ .001, SD = 20.64, 95% CI 28.45-40.44, d = 1.66). Lower extremity functional scale scores improved by a mean of 27.35 points (P ≤ .001, SD = 18.37, 95% CI 22.02-32.69, d =1.48). No complications were reported. One case converted to a total hip arthroplasty (2%). CONCLUSIONS Findings validated that the significant acetabular rim correction required to treat severe pincer morphology is safe and feasible via an arthroscopic approach. This, in addition to concomitant circumferential allograft labral reconstruction, resulted in improvement in patient-reported outcomes and radiographic measurements. LEVEL OF EVIDENCE Level IV, therapeutic case-series.

Abstract
Labral calcification may be part of the natural history of untreated femoroacetabular impingement syndrome (FAIS) in certain patients, making it a potential target for intervention with the goal of preserving the hip joint. The purpose of this study was to investigate if calcified labra create the appearance of lateral joint space narrowing and report minimum 2-year patient-reported outcome measures (PROMs) after treating patients with arthroscopic acetabuloplasty and labral reconstruction. Prospectively collected data on patients who underwent primary hip arthroscopy for FAIS and labral tearing from February 2015 to April 2021 were reviewed. Patients treated with primary labral reconstruction for an intraoperatively confirmed diagnosis of labral calcification were included. A sub-analysis was performed for patients with a minimum of 2-year follow-up. Preoperative and postoperative PROMs for the modified Harris hip score, nonarthritic hip score, the International Hip Outcome Tool-12 and visual analog scale for pain were recorded. Forty-six hips (46 patients) were included, with 19 hips in the sub-analysis. There was a significant increase in apparent lateral joint space width (JSW) measured on supine anteroposterior (AP) pelvis radiographs with no significant changes in medial and central JSW and significant decreases in the lateral and anterior center-edge angles and alpha angle. Patients experienced significant increases in PROMs and high rates of achieving psychometric thresholds. Patients presenting with FAIS and calcified labra may have apparent lateral joint space narrowing on pre-operative supine AP pelvis radiographs. These patients have low rates of full-thickness femoral head and acetabular cartilage pathology, this apparent narrowing can be corrected and excellent outcomes and survivorship can be achieved, with primary labral reconstruction.

Abstract
BACKGROUND The maximal outcome improvement threshold for willingness to undergo revision hip arthroscopy (MOWT) has not been defined yet. PURPOSE To determine the percentage MOWT in patients who underwent revision hip arthroscopy and to identify predictors of achieving the MOWT. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS An anchor question was provided to patients who underwent revision hip arthroscopy between April 2008 and June 2020 who returned for follow-up between August 2019 and June 2021 at one institution. Patients were included if they underwent revision hip arthroscopy, had answered the anchor question, and had baseline and postoperative minimum 1-year follow-up scores for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and the visual analog scale (VAS) for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia, previous hip conditions, or unwillingness to participate. Receiver operating characteristic analysis was used to determine the MOWT. Multivariate logistic regression was used to determine intraoperative predictors of achieving the MOWT. RESULTS In total, 153 patients (163 hips) were included, with 117 female hips (71.8%), a mean patient age of 34.3 ± 12.4 years, and an average follow-up time of 61.6 ± 42.7 months. It was determined that 77.3% of the patients reported that they would choose to undergo the revision hip arthroscopy again. The MOWT for the mHHS, NAHS, and VAS was 43.1%, 53%, and 33.4%, respectively. The probability of choosing to undergo revision surgery if the MOWT was achieved was 77.5%, 77.6%, and 79.2%, for the mHHS, NAHS, and VAS, respectively. Patients with residual cam-type morphology, which was addressed during the revision, were 2.3 times more likely to achieve the MOWT for the VAS (P = .014). CONCLUSION Patients who improved 43.1%, 53%, and 33.4% of their MOWT for the mHHS, NAHS, and VAS, respectively, were likely to be willing to undergo revision hip arthroscopy again. Moreover, the presence of residual cam-type femoroacetabular impingement morphology before their revision surgery was identified as a predictor to achieve the MOWT for the VAS.

[PMID: 34738159 DOI: 10.1007/s00167-021-06756-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Accepted: 09/27/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE The purpose of this study was to determine and establish the MCID for the NAHS at 2 years in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). METHODS Patients that underwent primary hip arthroscopy for FAIS between 2010 and 2016 were analyzed for eligibility. Data were collected from a single surgeon's hip arthroscopy database. MCID was calculated for the NAHS utilizing a distribution-based method. RESULTS The study included 298 patients (184 females) with an average age of 40.4 ± 13.0 years and average body mass index (BMI) of 25.7 ± 4.2 kg/m2. At baseline, the cohort's average NAHS score was 48.7 ± 13.6 and demonstrated an improvement of 36.5 ± 17.0 for NAHS at follow-up. This resulted in MCID values of + 8.5 for NAHS. CONCLUSION This is the first study to report the MCID (+ 8.5) for NAHS following primary hip arthroscopy, and as such, is a valuable contribution to future hip arthroscopy research.

Abstract
BACKGROUND Questions remain about whether circumferential labral reconstruction (CLR) using an iliotibial band (ITB) allograft can effectively restore the labral suction seal of the hip. HYPOTHESES (1) CLR with an ITB allograft >6.5 mm would restore distractive stability force to that of the intact labrum. (2) CLR with an ITB allograft >6.5 mm would achieve significantly superior distractive stability force compared with CLR with an ITB allograft <6.5 mm. STUDY DESIGN Controlled laboratory study. METHODS A total of 6 fresh-frozen pelves with attached femurs (n = 12 matched hemipelves) from male donors were procured and dissected free of all soft tissue, including the hip capsule but preserving the native labrum, transverse acetabular ligament, and ligamentum teres. Potted hemipelves were placed in a saline bath and securely fixed to the frame of a hydraulic testing system. A 500-N compressive load was applied, followed by femoral distraction at a rate of 5.0 mm/s until the suction seal ruptured. Force and femoral displacement were continually recorded. Force versus displacement curves were plotted, the maximum force was recorded, and the amount of femoral distraction to rupture the suction seal was determined. After intact testing, the labrum was excised, and specimens were retested using the same protocol. CLR was subsequently performed twice in a randomized fashion using (1) an ITB allograft with a width >6.5 mm (7.5-9.0 mm) and (2) an ITB allograft with a width <6.5 mm (4.5-6.0 mm). Specimens were retested after each CLR procedure. Force (in Newtons) and femoral distraction (in millimeters) required to rupture the suction seal were measured and compared between the 4 testing states (intact, deficient, CLR <6.5 mm, and CLR >6.5 mm) using repeated-measures analysis of variance. RESULTS On average, intact specimens required 148.4 ± 33.1 N of force to rupture the hip suction seal, which significantly decreased to 44.3 N in the deficient state (P < .001). CLR with ITB allografts <6.5 mm did not improve the maximum force (63 ± 62 N) from the deficient state (P = .42) and remained significantly lower than the intact state (P < .01). CLR with ITB allografts >6.5 mm recorded significantly greater force to rupture the suction seal (135.8 ± 44.6 N) compared with both the deficient and CLR <6.5 mm states (P < .01), with a mean force comparable with the intact labrum (P = .59). The amount of femoral distraction to rupture the suction seal demonstrated similar findings. CONCLUSION In a cadaveric model, CLR using ITB allografts >6.5 mm restored the distractive force and distance to the suction seal rupture to values comparable with hips with an intact labrum. CLR using ITB allografts >6.5 mm outperformed CLR with ITB allografts <6.5 mm, demonstrated by a significantly higher force to rupture the suction seal and increased distraction before the rupture. CLINICAL RELEVANCE The results of this cadaveric investigation suggest that using wider labral allografts during CLR will provide the distractive force required to rupture the suction seal and immediate postoperative stability of the hip, although further studies are required to determine if these results translate to improved clinical outcomes.

Patients With Concomitant Painful External Snapping Hip and Femoroacetabular Impingement Syndromes Reported Complete Snapping Resolution With Release of the Gluteus Maximus and Iliotibial Band, and Comparable Minimum 2-Year Outcomes to a Propensity-Matched Control Group. 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.

Lower Center Edge Angle and Bioipolar Cartilage Lesions Are Associated With Conversion to Hip Arthroplasty Within 2 Years Following Hip Arthroscopy: A Matched Cohort Analysis. Arthroscopy 2022; 38:1480-1485. [PMID: 34601009 DOI: 10.1016/j.arthro.2021.09.025] [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: 05/05/2021] [Revised: 09/17/2021] [Accepted: 09/19/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to determine whether radiographic parameters, intraoperative findings, patient-reported outcome measures, or intraoperative interventions that were performed differentiate those patients with >2 mm of joint space who convert under two years to total hip arthroplasty (THA) after undergoing hip arthroscopy for femoroacetabular impingement (FAI) when compared to those converting after 2 years. METHODS Included in this study were patients who underwent conversion to THA within 2 years of primary hip arthroscopy from a prospectively collected patient registry from 2007 to 2017. Patients who underwent early conversions to arthroplasty were matched 1:1 with patients who converted after 2 years, based upon age and gender. Preoperative outcome scores were collected, including Short Form-12, modified Harris Hip Score, and Hip Outcome Score. Additionally, variables from the preoperative radiographic evaluation, surgical findings, and procedures performed were also compared. RESULTS Forty-nine patients were included in the early conversion group and were matched with 49 patients in the later conversion group. Patients with lateral center edge angles of less than 25° were more likely to be in the early failure group [OR: 3.9; 95% CI: 1.01 to 15]. Patients with unipolar chondral defects on either the femoral (P = .128) or acetabular side (P = .656) were not at increased odds for early conversion compared to later conversion; however, those with bipolar chondral lesions at the time of surgery had increased odds of early conversions [OR: 3.3; 95% CI: 1.4 to 8] (P = .01). Neither surgical treatment nor preoperative patient-reported outcome measures were associated with early conversion. CONCLUSIONS In patient with >2 mm of joint space, lateral center edge angles of less than 25° and those with bipolar articular cartilage lesions seen at the time of hip arthroscopy are at increased risk for conversion to total hip arthroplasty within two years.

Abstract
PURPOSE To perform a systematic review comparing outcomes of segmental versus circumferential arthroscopic labral reconstruction as a treatment for symptomatic irreparable or unsalvageable acetabular labral pathology. METHODS A systematic review was conducted according to PRISMA guidelines using defined inclusion and exclusion criteria. The study groups were divided into segmental and circumferential labral reconstructions. Studies with <2 years follow up, overlapping patient populations, or indications for labral reconstruction other than irreparable or unsalvageable pathology were excluded. RESULTS The literature search resulted in nine included publications. Five studies presented data on segmental labral reconstruction (166 hips in 164 patients), and seven studies presented data on circumferential labral reconstruction (261 hips in 253 patients). All circumferential reconstruction studies used allograft only, while segmental studies used a combination of autograft and allograft. The range of conversion to total hip arthroplasty was 9.1% to 26.8% in the segmental studies and 3.1% to 9.9% in the circumferential studies. The modified Harris Hip Score (mHHS) was the only patient-reported outcome measure reported in three or more studies in both groups. The mean change from preoperative to postoperative mHHS ranged from 17.8 to 29 in the segmental group and from 20.4 to 31.7 in the circumferential group. Weighted estimates were not calculated due to significant heterogeneity for both the segmental and circumferential groups (I2 = 63.9% and 72.9%, respectively). CONCLUSIONS Segmental and circumferential reconstructions are both reasonable options for arthroscopic treatment of irreparable or unsalvageable labral pathology. Articles in both groups demonstrated improvement in patient-reported outcomes (mHHS). Because of study heterogeneity, low level of evidence, and high risk of bias, the scores were unable to be directly compared. Although there are theoretical biomechanical and technical advantages of one technique over another, this systematic review did not demonstrate clinical superiority of either technique. LEVEL OF EVIDENCE Level IV, systematic review of level III and IV studies.

Abstract
The aim of this study was to analyze the long-term clinical outcomes of labral reconstruction in patients undergoing femoro-acetabular impingement (FAI) surgery and compare them with labral repair and debridement. This is a single-center, single-surgeon, retrospective match-paired study from a prospectively collected hip preservation database. All patients underwent a hip surgical dislocation for FAI surgery. Eight patients underwent labral reconstruction with the ligamentum teres and were matched on sex, age and body mass index with 24 labral repair and 24 labral debridement (1:3). Failure was defined as conversion to total hip replacement (THR) and patient-reported outcome measures (PROMs) were collected. Mean follow-up was 9.8 years ±2.6 (5.2–13.9). There was a significant improvement in postoperative PROMs in the three groups regarding the WOMAC total, WOMAC function, HOOS-QoL, HOOS-ADL and HOOS-SRA (P < 0.05). There was no statistical difference between the three groups regarding postoperative PROMs and change in PROMs (P > 0.05). A total of 10 hips underwent joint replacement surgery at a mean time of 7.9 ± 3.5 years (2.4–12). There was no statistically significant difference between the three groups regarding the conversion rate to THR (P = 0.64) or time between surgery and conversion to THR (P = 0.15). Compared to a match-pair group of labral repair and debridement, labral reconstruction with ligamentum teres provides similar survival with conversion to a THR as an endpoint, as well as similar improvement in PROMs. Labral treatment can be safely adapted at the nature of the labral lesion with a treatment ‘à la carte’.

Abstract
PURPOSE To determine whether arthroscopic osteochondroplasty demonstrated effectiveness in a pragmatic femoroacetabular impingement patient population embedded within FIRST (the Femoroacetabular Impingement RandomiSed controlled Trial). METHODS All cohort patients were not randomized and were followed prospectively with a follow-up assessment protocol identical to that in FIRST. The primary outcome was hip pain using a 100-point visual analog scale. Secondary outcomes included hip function (Hip Outcome Score, International Hip Outcome Tool-12), health utility (EuroQol 5 Dimensions), and health-related quality of life (Short Form-12) at 12 months, as well as operatively and nonoperatively treated hip complications at 24 months. We performed multivariable regressions to compare these outcomes between 3 groups of patients: (1) those randomized to lavage in FIRST, (2) those randomized to osteochondroplasty in FIRST, and (3) those who received osteochondroplasty as part of the cohort study. RESULTS All groups had improvements across all questionnaire outcomes from baseline to 12 months, with no significant differences. There were significantly more reoperations in the lavage trial group compared with those in the embedded cohort (adjusted odds ratio [aOR] 3.08; 95% confidence interval [CI] 1.23-7.73; P = .016). There were significantly more nonoperatively treated hip complications in the lavage trial group and in the osteochondroplasty trial group when compared with those in the embedded cohort (aOR 3.81; 95% CI 1.19-12.17; P = .024 and aOR 4.55; 95% CI 1.43-14.42; P = .010, respectively). CONCLUSIONS Hip arthroscopic osteochondroplasty and lavage led to improvement in hip pain, function, and health-related quality of life at 12 months across both randomized controlled trial (RCT) and cohort patients. The pragmatic cohort receiving osteochondroplasty had (1) significantly fewer complications than RCT patients, (2) significantly less reoperations than RCT patients randomized to arthroscopic lavage, and (3) fewer, although nonsignificant, reoperations than RCT osteochondroplasty patients. LEVEL OF EVIDENCE II, therapeutic.

Abstract
Purpose of Review The current review investigates outcomes and failure rates associated with arthroscopic circumferential allograft labral reconstruction of the hip, both as a revision and primary procedure in treating femoroacetabular hip impingement and labral-related pathology. Recent Findings Numerous studies within the last decade have demonstrated excellent patient-reported outcomes, high rates of return-to-play in athletes, and low failure rates in patients having undergone arthroscopic circumferential allograft labral reconstruction of the hip. Removal of chronically diseased and injured labral tissue can eliminate a significant pain-generator from the hip joint. Additionally, circumferential reconstruction of the labrum restores the hoop fiber strength and fluid seal akin to what would be seen with native, healthy labral tissue. Recent research has shown that arthroscopic circumferential allograft labral reconstruction may be used not only in the revision setting, but as a primary procedure. Circumferential labral reconstruction should be considered when a surgeon feels that the labrum is irreparable or has failed previous repair. Summary Arthroscopic circumferential allograft labral reconstruction of the hip can be utilized as treatment option not only in revision settings, but also in primary treatment for femoroacetabular impingement and labral pathology

Abstract
It is essential to be aware of the anatomy and biomechanics of the acetabular labrum in order to understand why it should be conserved. Vascularization comes from the capsule and also from the bone. The joint side contains numerous nerve endings, which explains why labral lesions are painful. It is involved in joint stabilization by maintaining a negative pressure inside the joint able to resist distraction. It acts as a seal. There are two main suture techniques: trans- and peri-labral. Translabral suture is better suited to a wide and solid labrum free of degenerative lesions. Both techniques should be known, and may be associated. Results are comparable. It is essential to manage the underlying pathology responsible for the labral lesion. Joint degeneration is associated with poor prognosis. It needs to be recognized and discussed with the patient, to avoid unrealistic expectations.

Abstract
PURPOSE To compare minimum 2-year follow-up patient-reported outcome scores (PROs) in patients who underwent primary acetabular circumferential and segmental labral reconstruction for irreparable labral tears and femoroacetabular impingement syndrome (FAIS). METHODS Data were reviewed from August 2010 to December 2017. Patients with primary labral reconstruction and minimum 2-year follow-up for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain were included. Circumferential and segmental reconstruction were selected in each case based on the extent of the labral pathology. Exclusion criteria were previous ipsilateral hip surgery/conditions, dysplasia, or Tönnis grade >1. Patients were propensity matched 1:1 based on age, sex, and body mass index. Secondary surgeries were reported. The P value was set at <.05. RESULTS In total, 144 hips were eligible, and 17 hips were lost to follow-up, leaving 127 hips (88.2%) for analysis. Eighty hips underwent a segmental reconstruction, and 47 hips underwent a circumferential reconstruction. Forty-seven hips with circumferential reconstruction were matched to 47 hips with segmental reconstruction. The average follow-up and age for the segmental and circumferential groups were 29.0 ± 7.8 and 27.9 ± 7.0 months (P = .732) and 43.1 ± 9.4 and 44.7 ± 10.2 years (P = .442) respectively. The segmental and circumferential groups were 48.9% and 51.1% female, respectively. The groups achieved significant and comparable improvement for all PROs and rates of secondary surgeries. No differences were found for achieving the minimal clinically important difference (MCID) and the patient acceptable symptomatic state (PASS). The MCIDs for the segmental and circumferential groups were 76.7% and 77.8% for the mHHS, 64.9% and 77.8% for the HOS-SSS, 71.1% and 68.9% for the VAS, and 68.9% and 73.9% for the NAHS, respectively. The PASSs for the segmental and circumferential groups were 78.3% and 73.3% for the mHHS, 55.3% and 55.0% for the HOS-SSS, and 75.6% and 71.1% for the International Hip Outcome Tool 12, respectively. CONCLUSIONS At minimum 2-year follow-up, patients who underwent primary hip arthroscopy for either circumferential or segmental labral reconstruction for irreparable labra and FAIS reported significant improvement and similar postoperative scores for all PROs, with no difference in psychometric outcomes and rate of secondary surgeries. A customized approach, using the extent of the irreparable labral tear, seems to be an appropriate strategy. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

Minimum 2-Year Outcomes Following Arthroscopic Hip Labral Reconstruction in Adolescents and Young Adults. J Pediatr Orthop 2022; 42:83-89. [PMID: 34657092 DOI: 10.1097/bpo.0000000000001984] [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] [Indexed: 02/07/2023]
Abstract
BACKGROUND Labral repair is generally preferred when facing labral tears. When an irreparable labral tear in the context of femoroacetabular impingement syndrome is present, arthroscopic labral reconstruction has been proven to be a valid option for labral restoration. However, data on this procedure for the adolescent population is scarce. The purpose of the present study was to report minimum 2-year follow-up patient-reported outcome measures (PROMs) on adolescents and young adults following arthroscopic acetabular labral reconstruction. METHODS Data were prospectively collected and retrospectively reviewed on adolescents and young adults who underwent hip arthroscopy between March 2009 and June 2018. Inclusion criteria were labral reconstruction, baseline and minimum 2-year follow-up PROMs. Patients were excluded if they were unwilling to participate in the study, had Tönnis grade >1, or dysplasia. RESULTS Twenty-three hips (22 patients) that underwent labral reconstruction were included. Ten hips (10 patients) underwent primary labral reconstruction, and 13 hips (12 patients) underwent revision reconstruction. The mean age was 19.3 years and 56.5% of patients were males. All patients improved significantly at minimum 2 years for all PROMs (P<0.001) with high satisfaction. Patients in both groups demonstrated improvement for all PROMs, patient satisfaction, and a rate of achieving the minimal clinically important difference. CONCLUSION Arthroscopic labral reconstruction in adolescents and young adults demonstrated significant improvement and high patient satisfaction at minimum 2-year follow-up in the setting of irreparable labral tear. Favorable outcomes, high patient satisfaction, and high achievement rate for the minimal clinically important difference were obtained following labral reconstruction in this population the primary and revision scenarios. LEVEL OF EVIDENCE Level IV, case-series.

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 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.

Patients Require Less Time to Complete Preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Than Legacy Patient-Reported Outcome Measures. Arthrosc Sports Med Rehabil 2021; 3:e1413-e1419. [PMID: 34746845 PMCID: PMC8551417 DOI: 10.1016/j.asmr.2021.06.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 06/25/2021] [Indexed: 11/21/2022] Open
Abstract
Purpose To analyze time to completion of preoperative legacy patient-reported outcomes (PROs) and more recent computer adaptive Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires in patients with symptomatic femoroacetabular impingement syndrome undergoing primary hip arthroscopy. Methods A retrospective analysis was conducted on patients undergoing hip arthroscopy by a single fellowship-trained hip arthroscopist. Inclusion criteria were patients undergoing primary arthroscopic hip surgery and completion of at least 1 legacy PRO or PROMIS questionnaire at the preoperative time point. Exclusion criteria were history of contralateral or ipsilateral hip surgery, non-English-speaking patients, patients who completed PROs by phone or by paper form, and patients who did not complete preoperative PROs. Legacy PROs included modified Harris Hip Score (mHHS), Hip Outcome Score (HOS), International Hip Outcome Tool (iHOT-12), and Hip Pain Visual Analog Scale (VAS-Pain). PROMIS PROs included Physical Function (PROMIS-PF), Pain Interference (PROMIS-PI), and Depression (PROMIS-D). Only preoperative PROs were included in the analysis. Completion time was calculated using the questionnaire start and stop time reported by the survey collecting software. The median and interquartile range of each PRO were reported for analysis of central tendency and statistical dispersion, respectively. Results A total of 1,901 patients and 269 patients were included in the legacy and PROMIS groups, respectively. The median time required for completion of each PRO in (minutes: seconds) format was as follows: mHHS (1:29), HOS (3:58), iHOT (2:11), VAS-Pain (0:32), PROMIS-PF (0:46), PROMIS-PI (0:37), and PROMIS-D (0:43). The interquartile range of the middle 50% of respondents was as follows; mHHS (0:58), HOS (2:46), iHOT (1:22), VAS-Pain (0:28), PROMIS-PI (0:19), PROMIS-D (0:29), and PROMIS-PF (0:20). Conclusions This study supports that preoperative PROMIS forms require less time to complete than preoperative legacy PROs and are not significantly influenced by age, race, or workers compensation status.

Abstract
PURPOSE To perform a systematic review comparing patient-reported outcomes (PROs) in patients who underwent hip arthroscopy with labral repair versus labral reconstruction in the setting of femoroacetabular impingement syndrome (FAIS) and labral tears. METHODS A systematic review of the PubMed, Embase, and Cochrane databases was performed in May 2020 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and checklist. Articles were included in the analysis if they compared PROs between a labral repair and labral reconstruction cohort. For all PROs, the standardised mean difference (SMD) was calculated to compare the effect size of labral repair and labral reconstruction. RESULTS 10 comparative studies, with 582 reconstruction cases and 631 repair cases, were included in this analysis. The mean age for the reconstruction and the repair groups ranged from 27.0 years to 52.6 years and 27.5 years to 47.0 years, respectively. The mean follow-up for the reconstruction and the repair groups ranged from 24.0 months to 66.0 months and 24.0 months to 71.0 months, respectively. The modified Harris Hip Scores (mHHS) was favourable in 8 reconstruction studies (range 80.4-95.0) and 9 repair studies (range 84.1-93.0). Average NAHS scores for the repair and reconstruction cohorts ranged from 77.9-88.6 and 73.9-92.4, respectively. Additionally, the effect sizes regarding NAHS and mHHS scores were large (SMD > 0.8) in both the reconstruction and repair groups for the majority of studies. Finally, reconstruction patients underwent a subsequent total hip arthroplasty (THA) at a slightly higher rate. CONCLUSIONS In the setting of FAIS and labral tears, patients who underwent hip arthroscopy may expect significant improvement in PROs at short-term follow-up with either labral repair or labral reconstruction. Although, not statistically significant, the repair group trended towards higher scores and exhibited a lower risk of conversion to THA.

Abstract
Objective To report on the clinical outcome of patients undergoing combined arthroscopic treatment of labral resection and microfracture at the rim of acetabulum at a minimum 2‐year follow‐up. Methods The retrospective study included 38 patients undergoing hip arthroscopy for irreparable labral injury from 24 February 2014 to 26 February 2018. Thirteen patients were excluded owing to patient refusal of participation and concomitant diseases like synovial chondromatosis and dysplasia hip. The study group consisted of patients undergoing combined arthroscopic labral resection and microfracture at the rim of acetabulum (MICRO Group: 20 patients), arthroscopic labral resection alone (RESEC Group: five patients). Postoperative three‐dimensional (3D) double‐echo steady‐state (DESS) sequence with radial imaging at 3 Tesla were obtained and fluoroscopic image of the involved hip under distraction were used to observe the restoration of vacuum effect. Patient‐reported outcome scores (PROs) including the Harris Hip Score (HHS), Visual Analogue Score (VAS), Hip Outcome Score Activities of Daily Living Subscale (HOS‐ADL), Hip Outcome Score Sport‐Specific Subscale (HOS‐SSS) were collected and compared between two groups. Results All patients were followed up for at least 6 months. The follow‐up time of RESEC group is longer than MICRO group (46.6 months vs 23.9 months, P < 0.05). The 3D DESS imaging demonstrated intermediate signal intensity at the relative area where the labrum resected followed by microfracture at the acetabular rim in MICRO group. Meanwhile, regrowth of labrum‐like tissue was not observed in MRI imaging of the RESEC group. Furthermore, vacuum effect was more apparent in MICRO group compared with RESEC group. All PROs in both groups showed a statistically significant improvement at follow‐up compared with preoperative levels. RESEC group: HHS (73.0 vs 93.8, P < 0.05); HOS‐ADL (51.5 vs 89.1, P < 0.05); HOS‐SSS (47.8 vs 88.3, P < 0.05); VAS (6.4 vs 2.0, P < 0.05). MICRO group: HHS (70.5 vs 91.5, P < 0.05); HOS‐ADL (52.4 vs 87.0, P < 0.05); HOS‐SSS (48.1 vs 86.5, P < 0.05); VAS (6.3 vs 1.6, P < 0.05). One patient of MICRO group had transient neurapraxias of the pudendal nerve that resolved completely by 3 months. There showed no statistically significant difference between groups regarding the preoperative and postoperative PROs. Conclusion Compared to labral resection, combined arthroscopic labral resection and microfracture at the rim of acetabulum is able to fulfill the labral defect area with the potential to restore the seal effect of labrum as an effective and safe option for irreparable segmental labral tears.

Abstract
Appropriate labral tear management is one of the principal priorities of hip-preservation surgery. The labrum's role in the stability and biomechanics of the hip and preservation of the suction seal has been thoroughly demonstrated. Favorable patient-reported outcomes with labral reconstruction and, more recently, labral augmentation have shown that these are viable reconstructive procedures in the setting of irreparable labra. A wide variety of grafts have been used for these advanced labral restoration techniques. The present Technical Note will describe a detailed arthroscopic circumferential labral reconstruction using the pull-through technique with knotless all-suture anchors. The benefits of such can be applied to both segmental and circumferential labral reconstruction procedures, as well as labral augmentation, based on the intraoperative findings and preference of the surgeon.

Abstract
BACKGROUND There is a paucity of literature on arthroscopic capsular autograft labral reconstruction. PURPOSE To report midterm functional outcomes for patients undergoing acetabular labral repair with capsular autograft labral reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS This is a retrospective case series of prospectively collected data on patients who underwent arthroscopic acetabular labral repair by the senior surgeon between March 2013 and August 2018. The inclusion criteria for this study were adult patients aged 18 years or older who underwent primary hip arthroscopy for arthroscopic capsular autograft labral reconstruction. Exclusion criteria were <2 years of postoperative follow-up, elective disenrollment from study before 2-year follow-up, or repeat ipsilateral hip surgery before 2-year follow-up. Intraoperatively, patients underwent capsular autograft hip labral reconstruction if they were found to have a labrum with hypoplastic tissue (width <5 mm), complex tearing, or frank degeneration of native tissue. Clinical outcome data consisted of patient-reported outcome measures. RESULTS A total of 97 hips (94 patients) met the inclusion criteria with a mean final follow-up of 28.2 months (95% CI, 26.0-30.4). Patients had a mean age of 39.0 years (95% CI, 36.8-41.2) with a mean body mass index of 25.8 (95% CI, 24.9-26.7). When compared with baseline (40.4 [95% CI, 36.7-44.2]), the mean international Hip-Outcome Tool-33 (iHOT-33) scores were significantly greater at 3-month (60.9 [95% CI, 56.8-64.9]; P < .001), 6-month (68.8 [95% CI, 64.7-72.9]; P < .001), 12-month (73.2 [95% CI, 68.9-77.5]; P < .001), and final (76.6 [95% CI, 72.4-80.8]; P < .001) follow-up. At 2-year follow-up, 76.3%, 65.5%, and 60.8% of patients' iHOT-33 scores exceeded clinically meaningful outcome thresholds for minimally clinically important difference (MCID), patient-acceptable symptomatic state, and substantial clinical benefit, respectively. CONCLUSIONS In this study of 97 hips undergoing arthroscopic labral repair with capsular autograft labral reconstruction, we found favorable outcomes that exceeded the MCID thresholds in the majority of patients at a mean 28.2 months' follow-up. Future studies should compare outcomes between this technique and other methods of autograft and allograft reconstruction to determine differences in patient-reported outcomes, donor-site morbidity, and complications.

Abstract
BACKGROUND There is a paucity of midterm outcome data on hip revision arthroscopic surgery. PURPOSE (1) To report minimum 5-year patient-reported outcome measurement scores (PROMSs) in patients who underwent revision hip arthroscopy, (2) to compare minimum 5-year PROMSs with a propensity-matched control group that underwent primary hip arthroscopy, and (3) to compare the rate of achieving the minimal clinically important difference (MCID) at minimum 5-year follow-up between the revision group and the propensity-matched control primary group. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected between June 2008 and April 2014. Patients were included who underwent revision hip arthroscopy with preoperative and minimum 5-year follow-up scores for the modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. Patients with Tönnis grade >1 or with hip conditions such as avascular necrosis, Legg-Calve-Perthes disease, Ehlers-Danlos syndrome, and pigmented villonodular synovitis were excluded. A subanalysis was performed against a propensity-matched control group that underwent primary surgery. Groups were propensity matched in a 1:2 ratio for sex, age, body mass index, and follow-up time. RESULTS A total of 127 revision arthroscopies (113 patients) were included, and the mean ± SD follow-up time was 72.8 ± 23.3 months. The revision group was 74.0% female, and the average age and body mass index were 34.9 ± 12.4 years and 24.8 ± 4.2, respectively. The revision group demonstrated improvement for all PROMSs and reached the MCID for the mHHS (66.1%), HOS-SSS (68.4%), NAHS (66.9%), and VAS (80.0%). All revision cases were propensity matched to 254 primary arthroscopy cases. PROMSs in the revision group were lower than those of the control group before and after surgery. Delta values were similar between groups for all PROMSs. There were no differences in rates of achieving the MCID. The relative risk of arthroplasty conversion was 2.6 (95% CI, 1.5-4.6) for the revision group as compared with the primary group. CONCLUSION Significant improvement in all PROMSs, including the VAS, and high patient satisfaction at minimum 5-year follow-up were reported after revision hip arthroscopy. A high proportion of patients in the revision cohort reached the MCID for the mHHS, HOS-SSS, NAHS, and VAS, with similar rates and magnitudes of improvement relative to the control group. As expected, these data indicate that patients undergoing primary hip arthroscopy have higher PROMSs before and after surgery and lower rates of conversion to arthroplasty.

Abstract
BACKGROUND There is a paucity in the literature reporting patient-reported outcome (PRO) scores and the minimal clinically important difference (MCID) after revision hip arthroscopic surgery with circumferential labral reconstruction. PURPOSE To report minimum 2-year PRO scores and the rate of achieving the MCID in patients who underwent revision hip arthroscopic surgery with circumferential labral reconstruction in the setting of irreparable labral tears. STUDY DESIGN Case series; Level of evidence, 4. METHODS Data were retrospectively reviewed for all patients who underwent revision hip arthroscopic surgery between February 2016 and November 2017. Patients were included if they had undergone circumferential labral reconstruction and had preoperative and postoperative scores for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sport-Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), 12-Item Short Form Health Survey physical and mental components (SF-12 P and SF-12 M, respectively), Veterans RAND 12-Item Health Survey physical and mental components (VR-12 P and VR-12 M, respectively), and visual analog scale (VAS) for pain. Exclusion criteria were Tönnis grade >1, Legg-Calve-Perthes disease, slipped capital femoral epiphysis, fractures, hip dysplasia, or revision labral treatment different from circumferential labral reconstruction. The MCID was calculated. Secondary surgical procedures were documented. RESULTS A total of 26 hips (26 patients; 61.5% female) were included. The mean age and body mass index were 33.2 ± 10.4 years and 25.5 ± 4.9, respectively. Significant improvements were reported for the mHHS (17.0 ± 19.5; P = .0002), NAHS (17.9 ± 16.7; P < .0001), HOS-SSS (21.7 ± 23.1; P = .0005), VAS (-2.2 ± 3.0; P = .006), iHOT-12 (25.8 ± 32.5; P = .0007), SF-12 P (8.5 ± 11.2; P = .001), and VR-12 P (8.9 ± 11.6; P = .001). Rates of meeting the MCID for the mHHS, NAHS, HOS-SSS, iHOT-12, and VAS were 76.9%, 80.0%, 65.0%, 62.5%, and 69.2%, respectively. No case of re-revision arthroscopic surgery was documented, but 1 case of conversion to total hip arthroplasty was documented at 38.6 months. CONCLUSION In the setting of revision hip arthroscopic surgery and irreparable labral tears, circumferential labral reconstruction resulted in significant improvements in all PRO and VAS scores at a minimum 2-year follow-up with a high rate of achieving the MCID.

Consensus-based classification system for intra-operative management of labral tears during hip arthroscopy-aggregate recommendations from high-volume hip preservation surgeons. J Hip Preserv Surg 2021; 7:644-654. [PMID: 34377508 PMCID: PMC8349576 DOI: 10.1093/jhps/hnab043] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 03/16/2021] [Indexed: 11/13/2022] Open
Abstract
The purpose of this study was to survey high-volume hip preservation surgeons regarding their perspectives on intra-operative management of labral tears to improve decision-making and produce an effective classification system. A cross-sectional survey of high-volume hip preservation surgeons was conducted in person and anonymously, using a questionnaire that is repeated for indications of labral debridement, repair and reconstruction given the torn labra are stable, unstable, viable or non-viable. Twenty-six high-volume arthroscopic hip surgeons participated in this survey. Provided the labrum was viable (torn tissue that is likely to heal) and stable, labral debridement would be performed by 76.92% of respondents for patients >40 years of age and by >84% of respondents for stable intra-substance labral tears in patients without dysplasia. If the labrum was viable but unstable, labral repair would be performed by >80% of respondents for patients ≤40 years of age and > 80% of respondents if the labral size was >3 mm and located anteriorly. Presence of calcified labra or the Os acetabuli mattered while deciding whether to repair a labrum. In non-viable (torn tissue that is unlikely to heal) and unstable labra, labral reconstruction would be performed by 84.62% of respondents if labral size was <3 mm. The majority of respondents would reconstruct calcified and non-viable, unstable labra that no longer maintained a suction seal. Surgeons performing arthroscopic hip labral treatment may utilize this comprehensive classification system, which takes into consideration patient age, labral characteristics (viability and stability) and bony morphology of the hip joint. When choosing between labral debridement, repair or reconstruction, consensus recommendations from high-volume hip preservation surgeons can enhance decision-making.

Abstract
PURPOSE To assess mid- to long-term patient-reported outcomes (PROs) of hip arthroscopy as well as the rates of secondary surgery and to identify indications for surgery and noted predictors of failure. METHODS A systematic review of the current literature was performed with the terms "hip arthroscopy," "outcomes," "patient-reported outcomes," "mid-term," "5-year," "long-term," and "10-year" in the PubMed, Cochrane, and Embase databases in April of 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Data for study characteristics, patient demographics, follow-up time, indications for surgery, PROs, predictors of failure or unfavorable PROs, and rates of secondary hip preservation surgery and conversion to total hip arthroplasty were collected. RESULTS Thirteen articles were included. Four studies were level III and 9 were level IV. In total, 1571 hips were included, and the average follow-up time ranged from 60 to 240 months. The most common indications for hip arthroscopy were labral tears and femoroacetabular impingement syndrome. Twelve studies reported on PROs and all reported improvement at latest follow-up. The most reported on scores were the modified Harris Hip Score, Harris Hip Score, and the Hip Outcome Score-Sport Specific Subscale. When grouped based on average follow-up time, the conversion rates at the 5- and 10-year time points ranged from 3.0% to 17.9% and 2.4% to 32.5%, respectively. One study with 20-year follow-up reported a conversion rate of 41.0%. Osteoarthritis and increased age were the most cited predictors for secondary surgery or decreased PROs. CONCLUSIONS At mid- to long-term follow-up, patients who underwent primary hip arthroscopy demonstrated improvement in several PROs. There was great variability in rates for revision surgery and conversion to total hip arthroplasty. The most common indications for hip arthroscopy were labral tears and femoroacetabular impingement syndrome. Osteoarthritis and increased age were the most cited predictors for unfavorable outcomes. LEVEL OF EVIDENCE Level IV, systematic review of Level III and IV studies.

Abstract
Hip labrum reconstruction has been demonstrated to be a viable option for patients with irreparable labral tears. However, there is a lack of data analyzing patient and labral characteristics in those undergoing primary hip labral reconstruction. To use a machine learning technique to subcategorize patients who underwent labral reconstruction during primary hip arthroscopy and to determine if there may be varying pathology resulting in severe labral damage. Patients who underwent primary labral reconstruction between 2015 and 2018 were included. Patients with a prior ipsilateral hip surgery, who were unwilling to participate, or had incomplete preoperative data were excluded. Agglomerative hierarchical clustering analysis was conducted to identify the subgroups of patients. A comparison was performed for preoperative characteristics, intraoperative findings and procedures. Of the 191 patients who underwent primary labral reconstruction and were eligible, 174 were included in the clustering analysis. Two distinct groups were identified (Group 1: 112 patients, 64.4%; Group 2: 62 patients, 35.6%). Group 1 had a significantly higher proportion of females (61.6% versus 43.5%; P < 0.05), combined Seldes I and II labral tears (94.6% versus 54.8%; P < 0.05), and larger tears. Group 2 had a significantly higher rate of labral calcification (82.3% versus 3.6%; P < 0.05). The results of this study demonstrate two distinct groups of patients who underwent primary hip labral reconstruction: those with severe labral damage, and those with a calcified labrum. Approximately two-thirds were placed in the group with severe labral damage, while the other third had diminished quality secondary to calcific changes.

Abstract
PURPOSE OF REVIEW The last decade has seen a boom in hip arthroscopy with refined indications. Improved understanding of pathoanatomy and disease progression has allowed for the development of advanced techniques. Labral reconstruction has been developed to substitute a non-functional or absent labrum. It has become an important technique in the armamentarium of high-volume arthroscopic hip surgeons. RECENT FINDINGS Basic science studies have improved understanding of hip biomechanics in the presence and absence of a labrum with a labral reconstruction allowing for reconstitution of normalcy. Current techniques have shown success with autograft and allograft tissue options. While autograft tissue allows for easy access intra-operatively and maintains patient biology, donor site morbidity is possible. Allografts negate donor site morbidity and allow for an abundance of tissue but can be resource-intensive and face availability concerns. Recent studies support outcomes of labral reconstructions using both autograft and allograft. Promising results have also allowed for performing labral reconstruction in a primary setting. Labral reconstruction can be successfully performed using both autograft and allograft. Patient biology should be respected, and native hip biomechanics restored. The literature is plentiful for appropriate surgical decision-making allowing the surgeon with multiple graft choices depending on training, experience, and resources.

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
BACKGROUND Although hip arthroscopy has been shown to have favorable results, there is a paucity of literature describing predictive factors of 5-year clinical outcomes. PURPOSE To identify predictive factors of midterm outcomes after hip arthroscopy in a cohort of 1038 patients whose outcomes at minimum 2-year follow-up were previously reported. In addition, to provide a comparison of short- and midterm predictive factors in outcome measures after hip arthroscopy. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed on all patients undergoing hip arthroscopy between February 2008 and June 2012. Patients were included if they had minimum 5-year follow-up on 2 patient-reported outcomes: Nonarthritic Hip Score (NAHS) and modified Harris Hip Score. Patients were excluded if they had any previous ipsilateral hip conditions. Using bivariate and multivariate analyses, we analyzed the effect of 36 pre- and intraoperative variables on the NAHS, modified Harris Hip Score, and conversion to total hip arthroplasty. RESULTS A total of 1038 patients met the inclusion criteria for the 2-year study, and 860 met our listed inclusion criteria for the 5-year study. The mean follow-up time was 62.0 months (range, 60.0-120.0 months). The bivariate analysis identified 10 variables (4 categorical and 6 continuous) that were predictive of 5-year postoperative NAHS. For the multivariate analysis, 7 variables were identified as being significant: preoperative NAHS, body mass index (BMI), age, lateral joint space, alpha angle, revision hip arthroscopy, and acetabular microfracture. These 7 variables were also predictive in the bivariate analysis. Age, BMI, revision hip arthroscopy, Tönnis grade, sex, trochanteric bursectomy, femoral head cartilage damage, and acetabular inclination were significant predictors of conversion to total hip arthroplasty. CONCLUSION This study reports favorable midterm clinical outcomes in the largest cohort of hip arthroscopies with minimum 5-year follow-up in the literature to date. Seven variables were identified as being significant predictors of postoperative NAHS in the bivariate and multivariate analyses: preoperative NAHS, BMI, age, lateral joint space, alpha angle, revision hip arthroscopy, and acetabular microfracture. Of these, preoperative NAHS, BMI, age, and revision hip arthroscopy were predictive of 2- and 5-year postoperative NAHS. These predictive factors may prove useful to clinicians in determining indications for hip arthroscopy and counseling patients on its expected outcomes.

Abstract
Preservation of hip labral function is a primary goal in hip preservation surgery. Arthroscopic labral reconstruction in the hip is an alternative procedure for irreparable labrum in the nonarthritic hip population, with beneficial outcomes reported. Several challenges occur during labral reconstruction that make the procedure more difficult. The first is measuring the labral defect and matching the graft perfectly to the patient. The second is subsequent suture fixation and passage around the graft when it is loose within the joint. We propose a modification to the pull-through technique that both eliminates the inaccuracies in graft measurement and minimizes graft damage by eliminating the step of suture passage around the graft. This technique can be used for both segmental reconstruction or circumferential reconstruction of the hip labrum and can also accommodate knotless and knot-tied anchors. The advantages of this technique are increased procedure accuracy and efficiency.

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.

Circumferential Labral Reconstruction for Irreparable Labral Tears in the Primary Setting: Minimum 2-Year Outcomes With a Nested Matched-Pair Labral Repair Control Group. Arthroscopy 2020; 36:2583-2597. [PMID: 32109574 DOI: 10.1016/j.arthro.2020.02.014] [Citation(s) in RCA: 57] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 02/04/2020] [Accepted: 02/05/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE (1) To report minimum 2-year patient-reported outcome (PRO) scores of primary circumferential acetabular labral reconstruction using anterior tibialis allograft and the knotless pull-through technique in the setting of femoroacetabular impingement syndrome (FAIS) and irreparable labral tears and (2) to compare these PROs with a matched-pair primary labral repair group. METHODS Data were prospectively collected and retrospectively reviewed. Patients were included if they underwent primary circumferential labral reconstruction with anterior tibialis tendon allograft during February 2016 to April 2017 for irreparable labral tears and FAIS and had preoperative and minimum 2-year follow-up for modified Harris Hip Score (mHHS), Hip Outcome Score-Sport-Specific Subscale, Non-arthritic Hip Score, International Hip Outcome Tool 12 (iHOT-12), 12-Item Short Form Health Survey physical component and mental component, Veterans RAND 12-Item Health Survey physical component and mental component, and visual analog scale for pain. The exclusion criteria were previous ipsilateral hip conditions or surgical procedures, Tönnis grade 2 or higher, or dysplasia (lateral center-edge angle ≤ 18°). Labral tears were considered irreparable if the labrum appeared (1) to be mostly or completely calcified and (2) to be inadequate (nonviable) and not amenable for labral repair. The reconstruction group was matched 1:3 based on age, sex, and body mass index to a benchmark control group of hips undergoing labral repair from the same period. The minimal clinically important difference and patient acceptable symptomatic state for the mHHS and iHOT-12 score were calculated. RESULTS A total of 37 hips (37 patients) underwent circumferential labral reconstruction. There were 19 female patients (51.4%) and 18 male patients (48.6%). The mean age was 45.6 ± 11.6 years, and the average body mass index was 27.1 ± 5. At minimum 2-year follow-up, the circumferential labral reconstruction group showed statistically significant improvements in the mHHS, Non-arthritic Hip Score, Hip Outcome Score-Sport-Specific Subscale, iHOT-12 score, and visual analog scale score. All hips in the reconstruction group were successfully matched to 111 labral repair hips. At latest follow-up, improvements in all PROs between the 2 groups were comparable. The revision rates were 0% and 3.6% in the reconstruction and repair groups, respectively. CONCLUSIONS After primary hip arthroscopy, primary circumferential labral reconstruction using anterior tibialis allograft and the knotless pull-through technique in the setting of FAIS and irreparable labral tears resulted in significant improvements in several PROs at minimum 2-year follow-up and high patient satisfaction. Primary circumferential labral reconstruction reached comparable functional outcomes to those of a benchmark matched-pair primary labral repair control group. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
BACKGROUND Playing tennis is associated with various movements that can lead to labral injuries and may require arthroscopic surgery. While hip arthroscopies have demonstrated good outcomes in athletes, there is limited literature reporting patient reported outcomes (PROs) and return to sport (RTS) in competitive or recreational tennis players after arthroscopic hip surgery. Therefore, the purpose of the present study was to (1) report minimum five-year PROs and RTS in tennis players who underwent arthroscopic hip surgery and (2) compare outcomes between recreational and competitive tennis players. METHODS Data for patients who underwent hip arthroscopy surgery in the setting of femoroacetabular impingement and labral tears between March 2009 and January 2014 and who played tennis within one-year of surgery were retrospectively reviewed. Patients with preoperative and minimum five-year postoperative scores for the following PROs were included: modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sport Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. Patient Acceptable Symptomatic State (PASS) and Minimal Clinically Important Difference (MCID) for mHHS and HOS-SSS were calculated. RESULTS Of 28 patients, 31 hips met all inclusion and exclusion criteria of which 28 (90.3%) had minimum 5-year follow-up (mean: 72.8 ± 13.9 months). There were 3 professional, 3 collegiate, 2 high school, 2 organized amateur, and 18 recreational level tennis players. All PROs significantly improved at latest follow-up: mHHS from 67.0 to 86.7 (P < 0.001), NAHS from 65.9 to 87.2 (P < 0.001), HOS-SSS from 50.0 to 77.9 (P = 0.009), and VAS from 5.4 to 1.8 (P < 0.001). There was a 75.0% RTS rate. Additionally, 66.7% of patients achieved MCID and 83.3% achieved PASS for mHHS, and 63.6% achieved MCID and 58.3% achieved PASS for HOS-SSS. CONCLUSION Regardless of the level of participation, tennis players who underwent arthroscopic hip surgery reported statistically significant PRO improvements. A favorable rate of RTS was also achieved by players with a continued interest in playing. The data here may be useful in counseling tennis players of various levels who are considering arthroscopic treatment of a hip injury. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE OF REVIEW Hip arthroscopy and its indications continue to expand. Understanding the durability of hip arthroscopic procedures remains important not only for counseling patients, but also for determining the success of certain procedures or in certain populations. Survivorship is defined as the proportion of hip arthroscopy patients who have not yet gone on to periacetabular osteotomy (PAO), total hip arthroplasty (THA), and/or revision surgery. The purpose of this review is to summarize the recent literature pertaining to survivorship after certain hip arthroscopic procedures and certain special populations. RECENT FINDINGS There is yet to be level 1 evidence published with relation to survivorship following hip arthroscopy. The best evidence in the recent literature is contained in just rew long-term prospective studies demonstrating good to excellent survivorship following hip arthroscopy for femoroacetabular impingement (FAI). Unfortunately, the follow-up for other conditions treated by hip arthroscopy is more limited. In summary, hip arthroscopy indications continue to expand. The most common indication for surgery is FAI, and its recently published long-term survivorship demonstrates excellent durability. Other hip arthroscopic procedures, including labral reconstruction, adjunctive procedures such as capsular closure, and special populations such as athletes, also demonstrate excellent survivorship in shorter term follow-up. Further prospective research is needed to further define survivorship of various hip conditions, associated procedures, and special populations commonly treated with hip arthroscopy.

Abstract
BACKGROUND Different options, from reverse (anteverting) periacetabular osteotomy to hip arthroscopy, have been proposed for surgical treatment of femoroacetabular impingement syndrome (FAIS) in the setting of acetabular retroversion. PURPOSE (1) To report and analyze midterm patient-reported outcome scores (PROs) in patients with FAIS and labral tears in the setting of acetabular retroversion after isolated hip arthroscopy and (2) to compare these PROs with those of a propensity-matched control group without acetabular retroversion. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Prospectively collected data were retrospectively reviewed for patients who underwent hip arthroscopy for FAIS and labral tear treatment between June 2008 and March 2014. Inclusion criteria were as follows: acetabular retroversion, pre- and postoperative PROs for modified Harris Hip Score (mHHS), Non-arthritic Hip Score, Hip Outcome Score-Sports Specific Scale (HOS-SSS), and visual analog scale (VAS). Propensity score matching was utilized to identify a control group without acetabular retroversion matched 1:1 with similar age, sex, body mass index, acetabular and femoral head Outerbridge grade, preoperative lateral center-edge angle, and labral treatment. Patient acceptable symptomatic state (PASS) and/or minimal clinically important difference (MCID) for the mHHS, HOS-SSS, International Hip Outcome Tool-12, and VAS was calculated. RESULTS A total of 205 hips with acetabular retroversion were matched to a control group. The groups showed no difference in demographic variables. The retroversion group was composed of 139 female and 66 male hips, with a mean ± SD age of 23.81 ± 7.28 years and follow-up time of 65.24 ± 20.31 months. Intraoperative diagnostic data and procedures performed were similar between groups, except more femoroplasties were performed in the retroversion group. Significant improvements for the mHHS, Non-arthritic Hip Score, HOS-SSS, and VAS were seen for both groups at a mean 5-year follow-up. The proportion of patients who reached the PASS and MCID were similar. CONCLUSION In the setting of FAIS and labral tears, patients with acetabular retroversion can be safely treated with advanced hip arthroscopic techniques without reverse (anteverting) periacetabular osteotomy in a high-volume surgeon's hands. Patients with acetabular retroversion demonstrated favorable PROs at midterm follow-up. Furthermore, the proportion of patients reaching the MCID and PASS for several PROs were comparable with those of a propensity-matched control group without acetabular retroversion.

Abstract
BACKGROUND Labral tears are the most common findings in patients with symptomatic femoroacetabular impingement (FAI). The restoration of labral function is critical, and labral reconstruction has been proposed as an alternative for irreparable tears. PURPOSE To compare preoperative radiographic measurements and demographics of patients who underwent primary arthroscopic labral reconstruction versus primary labral repair and to identify factors that are predictive of the need for reconstruction. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Patients who underwent their index hip arthroscopic procedure between October 2010 and November 2018 and underwent either labral reconstruction or repair were included in the study. A total of 18 variables (14 radiographic and 4 demographic) were assessed in a bivariate comparison and analyzed in a multivariate logistic model. RESULTS A total of 251 primary reconstruction and 1147 primary repair procedures were included. The logistic model selected age, body mass index (BMI), Tönnis grade, lateral center-edge angle (LCEA), and alpha angle. The odds of reconstruction were 2.52 times higher in patients with Tönnis grade 1 than 0 (odds ratio [OR], 2.52 [95% CI, 1.82-3.49]). Each additional degree in the LCEA was associated with a 6% increase in the odds of reconstruction (OR, 1.06 [95% CI, 1.04-1.09]) and 4% for each additional degree in the alpha angle (OR, 1.04 [95% CI, 1.03-1.05]). Higher age (per log 10 unit) and BMI also increased the likelihood of reconstruction (OR, 11.29 [95% CI, 4.23-30.10] and OR, 1.03 [95% CI, 1.00-1.06], respectively). CONCLUSION In a multivariate analysis, factors identified as preoperative predictors for primary arthroscopic labral reconstruction in the setting of FAI and labral tears were Tönnis grade, LCEA, age, and BMI. These predictive factors may be useful for the clinician in determining the preoperative likelihood of primary labral reconstruction.
