Abstract
Background Symptomatic acetabular labral insufficiency in young, active patients is often treated with labral repair or reconstruction using fresh-frozen allografts. However, fresh-frozen tendon allografts do not have tissue or material properties that closely mimic acetabular labral fibrocartilage. Recent studies suggest meniscal allografts may be a better biomechanical, geometric, and material alternative for acetabular labrum reconstruction (ALR). Hypothesis Patients undergoing open ALR using fresh meniscus allograft transplants (MAT) will have better outcomes than those using fresh-frozen tendon allografts transplants (TAT) when comparing initial treatment success, diagnostic imaging assessments, and patient-reported pain and function scores. Study design Cohort Study. Methods With IRB approval, patients undergoing ALR with either TAT or MAT were included when initial (>1-year) outcomes data related to treatment success, pain, and function were available. In addition, a subcohort of patients underwent magnetic resonance imaging at least 6-months after surgery to evaluate allograft healing. Results Initial success rate, defined as no need for ALR revision or conversion to total hip arthroplasty (THA), was 88.9% for the entire group (n = 27, TAT = 5, MAT = 22) with 1 (20%) patient in the TAT cohort and 2 patients (9.9%) in the MAT cohort undergoing THA. In the MAT cohort, significant improvements were documented for physical function and pain scores at 1 year and final follow-up (FFU)(mean 26.8 months). Improvements in pain and function were noted at 1-year, but not at FFU (mean 59.6 months) in the TAT group. MRIs completed at least 6 months after labrum reconstruction showed improved allograft integrity and integration in the MAT cohort over the TAT cohort. Conclusion For acetabular labrum reconstructions, MAT was associated with a higher initial success rate, superior patient reported outcomes, and subjectively better MRI findings when compared to TAT.

[PMID: 37732715 PMCID: PMC10776144 DOI: 10.1097/corr.0000000000002860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Accepted: 08/17/2023] [Indexed: 09/22/2023]
Abstract
BACKGROUND No single graft type has been shown to have a benefit in acetabular labral reconstruction. The native labrum and lateral meniscus share many similarities, suggesting that the meniscus may be a promising source of graft material in labral reconstruction. QUESTIONS/PURPOSES Using a pig model, we sought to evaluate the healing process of fresh-frozen meniscus allograft for acetabular reconstruction by assessing (1) MRI and macroscopic observations of the meniscus allograft; (2) histologic appearance and immunohistologic evaluation of the meniscus allograft, native meniscus, and labrum; (3) microscopic assessment of the native labrum and meniscus via scanning electron microscopy; and (4) biomechanical assessment of tensile properties. METHODS Twelve skeletally mature male miniature Bama pigs (24 hips) were randomly divided into two groups: labral defect group (control) and lateral meniscus allograft group. The selection of Bama pig specimens was based on the similarity of their acetabular labrum to that of the human acetabular labrum, characterized by the presence of fibrocartilage-like tissue lacking blood vessels. The pigs underwent bilateral hip surgery. Briefly, a 1.5-cm-long section was resected in the anterior dorsal labrum, which was left untreated or reconstructed using an allogeneic lateral meniscus. The pigs were euthanized at 12 and 24 weeks postoperatively, and then evaluated by macroscopic observations and MRI measurement to assess the extent of coverage of the labral defect. We also performed a histologic analysis and immunohistologic evaluation to assess the composition and structure of meniscus allograft, native labrum, and meniscus, as well as scanning electron microscopy assessment of the microstructure of the native labrum and meniscus and biomechanical assessment of tensile properties. RESULTS Imaging measurement and macroscopic observations revealed that the resected area of the labrum was fully filled in the lateral meniscus allograft group, whereas in the control group, the labral defect remained at 24 weeks. The macroscopic scores of the meniscus allograft group (8.2 ± 0.8) were higher than those of the control groups (4.8 ± 1.0) (mean difference 3.3 [95% CI 1.6 to 5.0]; p < 0.001). Moreover, in the meniscus allograft group, histologic assessment identified fibrocartilage-like cell cluster formation at the interface between the graft and acetabulum; cells and fibers arranged perpendicularly to the acetabulum and tideline structure that were similar to those of native labrum could be observed at 24 weeks. Immunohistochemical results showed that the average optical density value of Type II collagen at the graft-acetabulum interface was increased in the meniscus allograft group at 24 weeks compared with at 12 weeks (0.259 ± 0.031 versus 0.228 ± 0.023, mean difference 0.032 [95% CI 0.003 to 0.061]; p = 0.013). Furthermore, the tensile modulus of the lateral meniscus allograft was near that of the native labrum at 24 weeks (54.7 ± 9.9 MPa versus 63.2 ± 11.3 MPa, mean difference -8.4 MPa [95% CI -38.3 to 21.4]; p = 0.212). CONCLUSION In a pig model, lateral meniscus allografts fully filled labral defects in labral reconstruction. Regeneration of a fibrocartilage transition zone at the graft-acetabulum interface was observed at 24 weeks. CLINICAL RELEVANCE The use of an autograft meniscus for labral reconstruction may be a viable option when labral tears are deemed irreparable. Before its clinical implementation, it is imperative to conduct a comparative study involving tendon grafts, which are extensively used in current clinical practice.

Abstract
The acetabular labrum is essential to maintaining the functional health of the hip joint through contributions to joint congruity, stability, and the negative pressure suction seal. Injury, overuse, long-standing developmental disorders, or failed primary labral repair can eventually lead to functional labral insufficiency requiring management via labral reconstruction. While numerous graft options exist for hip labral reconstruction, there is no current gold standard. The optimal graft should best mimic the native labrum with regard to geometry, structure, mechanical properties, and durability. This has led to the development of an arthroscopic technique for labral reconstruction with fresh meniscal allograft tissue.

Abstract
The acetabular labrum plays an important role in hip stability, intra-articular fluid pressurization and force distribution. For irreparable labral pathology, labral reconstruction is an increasingly adopted technique shown to decrease hip pain and improve function. We evaluated survivorship and clinical outcomes of allograft labral reconstruction using the mini-open anterior surgical approach. Twelve patients who underwent labral reconstruction using a semitendinosus tendon allograft (reconstruction group) were matched 1:3 based on age, gender, body mass index, year of surgery, preoperative Tönnis grade, previous hip surgery, residual hip pathology and extent of acetabular chondral lesion to a control group of 36 patients who underwent direct labral repair with anchors (refixation group). At a minimum follow-up of 2 years, patient-reported outcomes, radiological findings and failure rates were compared. The average age was 31.3 years (±13.6) for reconstruction and 34.7 (±10.2) for refixation. Both groups had similar preoperative symptomatic periods (P = 0.3), prevalence of residual hip pathology (P = 1.0) and prevalence of prior hip surgeries (P = 1.0). both groups had a significant improvement of modified Harris Hip scores and 36-Item Short-Form Health Survey physical scores. There was no statistically significant difference in conversion rates to total hip arthroplasty (25% versus 8.3%, P = 0.2); however, time to conversion was significantly longer in the reconstruction group (3.58 years ±1.04) compared to the refixation group (1.20 years± 0.93; P = 0.04). In conclusion, at a minimum of 2 years of follow-up, mini-open labrum reconstruction for severe insufficiency of acetabular labrum demonstrated comparable improvements in functional outcomes and significantly longer survivorship compared to labral refixation.

Abstract
➢ Arthroscopic hip labral reconstruction is a complex procedure which is growing in use as indications, techniques, and surgical expertise advance. ➢ Graft selection is an important component of labral reconstruction based on relative advantages and disadvantages of available types of autografts and allografts. ➢ The ideal graft should mimic the native acetabular labrum form and function while also being affordable, readily available, and associated with low morbidity. ➢ High rates of patient satisfaction and positive patient-reported outcomes have been reported after labral reconstruction using several graft types.

Abstract
Purpose of Review This literature review aims to survey the current knowledge about the management FAI in the setting of borderline hip dysplasia. Recent Findings With better understanding, hip arthroscopy has recently been advocated for treating mild or borderline hip dysplasia (BDH) with concomitant femoroacetabular impingement (FAI) despite early studies that condemned its use. Recent outcome data have demonstrated that hip arthroscopy is a viable option in BDH, with and without FAI, and has been gaining wider acceptance. Hip arthroscopy can address the concomitant soft tissue and bony intra-articular pathologies and obviate the necessity for other surgeries. Moreover, hip arthroscopy may be used as an adjuvant treatment to other procedures such as a periacetabular osteotomy (PAO). Summary Hip arthroscopy for BDH is an evolving procedure with promising short- and mid-term outcomes. The combination of BDH and FAI is becoming recognized as a problem in its own right, requiring dedicated treatment.

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
Currently, there is no consensus on the ideal graft for hip labral reconstruction. The purpose of this study was to describe the surgical technique and report the short-term outcomes after hip labral reconstruction using a peroneal longus allograft. Eleven patients diagnosed with femoracetabular impingement and irreparable damage to the acetabular labrum underwent labral reconstruction with a peroneus longus allograft. The average follow-up time was 227 days (range: 26-457 days). Pre-operative radiographic measurements included an average pre-operative center edge angle of 29.0° (range: 19° to 37°) and an average alpha angle of 62.9° (range: 55° to 71°). All patients underwent femoroplasty, with additional procedures including 7 acetabuloplasties and 6 microfractures. The average visual analogue score for pain improved from 4.91±2.17 preoperatively to 3.85±2.0 postoperatively but this was not significant (P=.26). No patients sustained post-operative complications or allograft failures during follow up. Compared to other acetabular labral reconstruction options, the strength and shape of thedcd peroneus tendon may best replicate the native hip labrum. The current findings of no immediate post-operative complications or early failures suggests the peroneus longus allograft may be a viable option for hip labrum reconstruction.

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
The acetabular labrum is essential for stability during physiologic motion of the hip. Labral repairs frequently are attempted in cases of primary tears, although labral reconstruction is an important alternative in the revision setting or in the primary setting when the tissue is unsalvageable. Labral reconstruction has been shown to restore the hip's suction-seal and fluid pressurization to that of the premorbid state, and cohort studies have demonstrated significantly improved patient-reported outcomes at midterm follow-up. Notably, the cost is of consideration during any reconstruction, and techniques have been described using both allograft and autograft sources. Autograft sources include the iliotibial band, ligamentum teres, gracilis tendon, and hip capsule. A previously described technique using the capsule was noted to hinder routine capsular closure. We present an alternative method for labral reconstruction using hip capsular tissue that is easily performed and allows for routine capsular closure.

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
Surgical treatment of labral injuries has shifted from debridement to preservation over the past decades. Primary repair and secondary augmentation or reconstruction techniques are aimed at restoring the labral seal and preserving or improving contact mechanics. Currently, the standard of care for non-repairable tears favours the use of auto- or allografts. As an alternative, we present our initial experience using a synthetic, off-the-shelf polyurethane scaffold for augmentation and reconstruction of segmental labral tissue loss or irreparable labral damage. Three patients aged 37–44 (two male, one female) with femoroacetabular impingement without associated dysplasia (Wiberg > 25°) or osteoarthritis (Tönnis <2) were included in this series. Labral reconstruction (one case) and augmentation (two cases) were performed using a synthetic polyurethane scaffold developed for meniscal substitution (Actifit®, Orteq Ltd, London, UK) and adapted to the hip. Clinical results were analysed with patient-reported outcomes (PROMs) using non-arthritic hip score (NAHS) and daily live activities hip outcome score (DLA HOS) and magnetic resonance images (MRI) at 2- and 4-year follow-up. Clinically improvement was seen in all PROMs at 4 years. The NAHS scores improved from 57.7 to 82.3 (50.9% improvement) and HOS from 59 to 79.3 (35.3% improvement). Last follow-up MRIs confirmed the presence of the scaffold; however, the scaffold signal was still hyperintense compared to native labrum. There was no shrinkage in any scaffold and no progression to hip osteoarthritis seen. Reconstruction or augmentation of segmental labral defects with a polyurethane scaffold may be an effective procedure. At 4 years after implantation, our small cases series resulted in improved hip joint function, reduced pain and scaffold preservation on follow-up imaging.

Acetabular labral reconstruction with medial meniscal allograft: preliminary results of a new surgical technique. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:515-521. [PMID: 34028622 DOI: 10.1007/s00590-021-02986-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/13/2021] [Accepted: 04/14/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE Reconstruction of the acetabular labrum during femoroacetabular impingement (FAI) surgery is accepted when the labrum is deficient and irreparable. Here we describe a novel technique using fresh-frozen medial meniscal allograft for labral reconstruction during surgical hip dislocation for correction of pincer FAI due to acetabular overcoverage. METHODS The results from seven hips (six patients) that underwent this procedure with 1 year minimum follow-up, and radiographs are presented. RESULTS Six of the seven hips had improvements in pain, hip flexion, hip abduction, and Merle d'Aubigné-Postel scores. Only one patient with pre-existing osteoarthritis underwent reoperation with conversion to total hip arthroplasty. All digastric trochanteric osteotomies healed, and there were no cases of femoral head osteonecrosis or progression of Tönnis grades. CONCLUSIONS The medial meniscus is a morphologically and clinically suitable option for labral reconstruction and effectively restores the hip fluid seal.

Arthroscopic Triple Reconstruction in the Hip Joint: Restoration of Soft-Tissue Stabilizers in Revision Surgery for Gross Instability. Arthrosc Tech 2021; 10:e1239-e1248.

Abstract
Gross hip instability in an active adult with previous normal hip anatomy is usually due to disruption of the static stabilizers of the hip joint. Although such a disruption can result from a high-grade injury, it can be iatrogenic after previous hip arthroscopy. The patient may present with a painful limp and recurrent subluxation sensation in the affected hip joint. Revision hip arthroscopy in this scenario is generally complicated, and it is not uncommon for all the soft-tissue stabilizers to be compromised. The labrum, ligamentum teres (LT), and capsule of the hip joint are often so damaged that reparation is not an option. Reconstruction of the torn LT is an established method to add secondary stability while addressing the labral pathology in the hip joint with microinstability. Concomitant reconstruction of all the static restraints has yet to be described addressing triple instability. This Technical Note presents a stepwise approach, including tips and pearls, for arthroscopic triple reconstruction of the labrum, LT, and capsule. We believe this method is a safe and reproducible way to effectively treat gross hip instability in young patients.

Abstract
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
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
The Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ) was created for patient-reported outcome measures (PROMs) and to evaluate the conditions of patients with hip disease. Nevertheless, the validity of the JHEQ for patients with hip labral tears remains unclear. Therefore, we validated the JHEQ in patients with labral tears. There were 51 patients (mean age 44.5, range 18-60 years; 31 women). Thirty-two patients had right-sided tears, 29 underwent hip arthroscopy, 32 had femoroacetabular impingement and 15 had developmental hip dysplasia. Five PROMs included in the JHEQ were evaluated using test-retest methods. Statistical analysis was performed using SPSS software according to the COnsensus-based Standards for the selection of health status Measurement Instruments checklist. The intra-class correlation coefficient (1, 2) of all JHEQ scores (84 points) was 0.88 and Cronbach's α was 0.94. Bland-Altman analysis revealed good test-retest reliability for the JHEQ. The Spearman's rank test, including the SF-36 subscale, showed a high correlation with physical functioning [1, 0.67 (P < 0.01); 2, 0.65 (P < 0.01)], body pain [1, 0.54 (P < 0.01); 2, 0.53 (P < 0.01)] and physical component summary [1, 0.55 (P < 0.01); 2, 0.55 (P < 0.01)]. The value of minimal important change (22.9) was higher than that of smallest detectable change (3.21), suggesting that the JHEQ has adequate responsiveness. We demonstrated the reliability, validity and responsiveness of the JHEQ in Japanese patients with hip labral tears. JHEQ is a valid assessment tool not only for patients with hip osteoarthritis or osteonecrosis but also for those with hip labral tears.

Abstract
In the last 15 years, the diagnosis of femoroacetabular impingement has become more frequent; with the advance of surgical indications, different techniques have been developed. Surgical treatment includes a wide variety of options, namely: periacetabular osteotomy, surgical hip dislocation, arthroscopy with osteochondroplasty via a small incision, modified anterior approach technique, and exclusively arthroscopic technique. The type of approach should be chosen according to the complexity of the morphology of the femoroacetabular impingement and to the surgeon's training. The techniques most used today are arthroscopy, surgical dislocation of the hip, and periacetabular osteotomy. The present article aims to describe the current main surgical techniques used to treat femoroacetabular impingement, their indications, advantages and disadvantages, complications and clinical results.
