Failed labral reconstruction of the hip can be successfully revised to another labral reconstruction: improved patient-reported outcomes at a minimum of 2-year follow-up

Abstract The purpose of this study was to validate the success of revision arthroscopic circumferential allograft labral reconstruction (CLR) in nonarthritic hips, which, in the rare case of failure, had previously undergone labral reconstruction by the same surgeon. Using a minimum of 24-month follow-up, data from 24 hips having undergone revision CLR were analyzed to determine improvements in patient-reported outcomes (PROs). All included cases completed a minimum of 24 months follow-up, with a success rate of 96%. All PROs improved significantly, with exceptionally strong measures of effect. Modified Harris Hip Scores improved by a mean of 26.68 points, with 88% of patients meeting the minimal clinically important difference (MCID) (+6.49, P ≤ .001, d = 1.32). Lower Extremity Functional Scale scores improved by a mean of 21.88 points, with 78% of patients meeting the MCID (+7.79, P ≤ .001, d = 1.32). Pain as rated by the Visual Analog Scale, including at rest, during activities of daily living, and with sports, was significantly improved with strong measures of effect, with >75% of patients having met the MCID. This study validated that a failed labral reconstruction of the hip can be revised safely and effectively to another labral reconstruction of the hip. While labral reconstruction has broadly been shown to result in highly favorable outcomes, this study demonstrated that in the rare case of failure, revision CLR is not only feasible but results in improved pain and functionality.

Indirect Head of the Rectus Femoris Tendon as a Graft for Segmental Hip Labral Reconstruction: An Anatomic, Radiographical, and Biomechanical Study in Comparison With Iliotibial Labral Reconstruction

Background: The indirect head of the rectus femoris (IHRF) tendon has been used as an autograft for segmental labral reconstruction. However, the biomechanical properties and anatomic characteristics of the IHRF, as they relate to surgical applications, have yet to be investigated. Purpose: To (1) quantitatively and qualitatively describe the anatomy of IHRF and its relationship with surrounding arthroscopically relevant landmarks; (2) detail radiographic findings pertinent to IHRF; (3) biomechanically assess segmental labral reconstruction with IHRF, including restoration of the suction seal and contact pressures in comparison with iliotibial band (ITB) reconstruction; and (4) assess potential donor-site morbidity caused by graft harvesting. Study Design: Descriptive laboratory study. Methods: A cadaveric study was performed using 8 fresh-frozen human cadaveric full pelvises and 7 hemipelvises. Three-dimensional anatomic measurements were collected using a 3-dimensional coordinate digitizer. Radiographic analysis was accomplished by securing radiopaque markers of different sizes to the evaluated anatomic structures of the assigned hip.Suction seal and contact pressure testing were performed over 3 trials on 6 pelvises under 4 different testing conditions for each specimen: intact, labral tear, segmental labral reconstruction with ITB, and segmental labral reconstruction with IHRF. After IHRF tendon harvest, each full pelvis had both the intact and contralateral hip tested under tension along its anatomic direction to assess potential site morbidity, such as tendon failure or bony avulsion. Results: The centroid and posterior apex of the indirect rectus femoris attachment are respectively located 10.3 ± 2.6 mm and 21.0 ± 6.5 mm posteriorly, 2.5 ± 7.8 mm and 0.7 ± 8.0 mm superiorly, and 5.0 ± 2.8 mm and 22.2 ± 4.4 mm laterally to the 12:30 labral position. Radiographically, the mean distance of the IHRF to the following landmarks was determined as follows: anterior inferior iliac spine (8.8 ± 2.5 mm), direct head of the rectus femoris (8.0 ± 3.9 mm), 12-o’clock labral position (14.1 ± 2.8 mm), and 3-o’clock labral position (36.5 ± 4.4 mm). During suction seal testing, both the ITB and the IHRF reconstruction groups had significantly lower peak loads and lower energy to peak loads compared with both intact and tear groups (P = .01 to .02 for all comparisons). There were no significant differences between the reconstruction groups for peak loads, energy, and displacement at peak load. In 60° of flexion, there were no differences in normalized contact pressure and contact area between ITB or IHRF reconstruction groups (P > .99). There were no significant differences between intact and harvested specimen groups in donor-site morbidity testing. Conclusion: The IHRF tendon is within close anatomic proximity to arthroscopic acetabular landmarks. In the cadaveric model, harvesting of the IHRF tendon as an autograft does not lead to significant donor-site morbidity in the remaining tendon. Segmental labral reconstruction performed with the IHRF tendon exhibits similar biomechanical outcomes compared with that performed with ITB. Clinical Relevance: This study demonstrates the viability of segmental labral reconstruction with an IHRF tendon and provides a detailed anatomic description of the tendon in the context of an arthroscopic labral reconstruction. Clinicians can use this information during the selection of a graft and as a guide during an arthroscopic graft harvest.

Secondary Hip Labral Reconstruction Yields Inferior Minimum 2-Year Functional Outcomes to Primary Reconstruction Despite Comparable Intraoperative Labral Characteristics

PurposeTo compare intraoperative labral characteristics and minimum 2-year functional outcomes of allograft labral reconstruction in primary versus revision hip arthroscopy across multiple orthopedic centers. MethodsA retrospective multicenter hip arthroscopy registry was queried for patients with completed labral reconstruction surgeries from January 2014 to March 2023 with completed 2-year international Hip Outcome Tool-12 (iHOT-12) reports. Age, sex, and major intraoperative variables were also collected. Patients were placed in cohorts based on whether their arthroscopic allograft labral reconstruction was a primary procedure or secondary procedure (reconstruction following failed hip arthroscopy). One-way ANOVA was performed on continuous variables. Chi-squared test was performed on categorical variables. Achievement of minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and Substantial Clinical Benefit (SCB) was also assessed. ResultsIn total, 77 patients met the inclusion and exclusion criteria and had complete information. The primary reconstruction group (n=50) was significantly older than the secondary reconstruction group (n=27) (47.5 ± 10.5 vs 39.1 ± 8.8 years; P = 0.001). In both cohorts, most patients had labral bruising, advanced labral degeneration, and/or grade III complexity of labral tearing. There was no difference in any recorded intraoperative findings (P = 0.160, P = 0.783, P = 0.357, respectively). Each cohort experienced significant improvement in iHOT-12 scores (P < .0001). However, patients undergoing secondary labral reconstruction reported inferior iHOT-12 scores (60.1 ± 29.2 vs 74.8 ± 27.0; P = 0.030). Patients undergoing primary reconstruction were more likely to reach MCID, PASS, and nearly normal SCB (92 vs 66.7%, P = 0.024; 68.0 vs. 40.7%, P = 0.021; 76.0 vs 48.1%, P = 0.014, respectively). ConclusionsPrimary and secondary allograft labral reconstruction show clinical improvement, but primary reconstruction demonstrates better outcomes and higher percentage of patients reaching MCID, PASS and nearly normal SCB than reconstruction in the revision setting. Level of EvidenceIII, retrospective comparative prognostic case-control study.

Similar Clinical Outcomes for Arthroscopic Labral Reconstruction in Irreparable Cases Using the Indirect Head of the Rectus Femoris Tendon With an All-Inside Technique for Small Defects and the Iliotibial Band for Large Defects

To evaluate the clinical outcomes and satisfaction rate of patients who underwent arthroscopic labral reconstruction for an irreparable labral tear with a minimum follow-up period of 2 years. Additionally, this study aimed to compare 2 different reconstructive techniques for small and large labral defects: the indirect head of the rectus femoris tendon (IHRFT) autograft with an all-inside technique used to repair small defects (≤3 hours) and the iliotibial band (ITB) autograft for large defects (>3 hours). A total of 24 hips treated with the IHRFT were compared with 24 hips treated with the ITB. All patients underwent clinical evaluation before surgery and during the most recent follow-up (42 ± 18 months). The evaluation included patient satisfaction, the modified Harris Hip Score, the Non-Arthritic Hip Score, the Hip Outcome Score, the Hip Outcome Score-sport subscale, the 12-item International Hip Outcome Tool, and the visual analog scale pain score. All clinical scores were significantly improved (P < .001) at the latest follow-up in both groups. The final satisfaction was 7.1 ± 2.8 and 8.8 ± 1.6 for the IHRFT and ITB groups, respectively (P= .006). There was a significant difference in age (41.2 ± 6.0 years for the IHRFT group and 33 ± 8.5 for the ITB group; P= .004) and in surgery time (147.3 ± 39.4 minutes for the ITB group and 105.3 ± 25.7 for the IHRFT group; P < .001). One patient (4.2%) in the IHRFT group underwent total hip arthroplasty after 21.3 months (P= .999). At the 2-year follow-up, treating small defects using IHRFT and larger defects using ITB resulted in good patient-reported outcome measures with a low rate of complications and failures. The ITB group reported a higher level of satisfaction at the final follow-up. Level III, retrospective comparative therapeutic trial.

Statistical fragility analysis of reported outcomes associated with surgical management of acetabular labral pathology.

The purpose of this study was to analyse the robustness of comparative research that evaluated arthroscopic labral reconstruction versus other surgical management of labral pathology. Key measures of statistical fragility include the fragility index and fragility quotient.ß. 12 comparative studies that evaluated the use of arthroscopic labral reconstruction were included in this study. Particular attention was placed on evaluating trends, either statistically significant or not, of functional improvement, complication rates, need for total hip arthroplasty (THA) and revision rates with associated p-values. The analysis involved in this study was the Fragility Index, which is the median number of events required to change the statistical significance of a particular outcome, thus changing the study conclusions. Fragility quotient was calculated for each study as the fragility index divided by sample size. Of the 12 studies that were included for analysis, there were a total of 25 reported outcomes, 8 of which were statistically significant (p < 0.05). The statistical fragility for the significant outcomes were 2.5 (interquartile range [IQR]: 1.5-3.5), whereas the median statistical fragility for insignificant results was 6 (IQR 4-9). The overall fragility index was 4 (IQR 3-7). The median of fragility quotients was 0.04 (IQR 0.01-0.07). This study demonstrated that comparative research regarding arthroscopic techniques of labral reconstruction may not be as statistically stable as previously hoped. In many of the reported outcomes, particularly the ones that were statistically significant, only a small percentage of event changes was required to change the significance of the study conclusions. This fragility is worrisome, since clinical decisions that rely on these reported outcomes may have a significant impact on long-term patient outcomes. It is, therefore, crucial to optimise patient outcomes by incorporating past literature and reported outcomes.

Arthroscopic Labral Reconstruction With a Modified Inferior Capsular Shift Allows Return to Sport and Excellent Outcomes in Contact and Noncontact Athletes With Anterior Shoulder Instability at Minimum 5-Year Follow-Up

PurposeTo compare return to sport, functional outcomes, recurrence of instability, and osteoarthritis(OA) between collision/contact and limited/non-contact athletes following arthroscopic labral reconstruction with a modified inferior capsular shift for anterior shoulder instability. MethodsAthletes underwent an arthroscopic labral reconstruction with a modified inferior capsular shift, by the senior author between 1999 and 2017. Inclusion criteria were labral stripping from 12(just beyond the biceps anchor) to 6 o’clock, less than 20% glenoid bone loss, active sports participation, and no prior surgery. Athletes were divided into collision/contact and limited/non-contact groups. Outcome measures, physical examination, and radiographic evaluation were collected at a minimum 5-year follow-up. Re-operations or any subjective laxity were considered failures. Radiographs were analyzed for OA utilizing Samilson-Prieto Radiological Classification. ResultsNinety-two patients underwent arthroscopic labral reconstruction with a modified inferior capsular shift. Sixty-four met the inclusion criteria. Thirty-eight(age=26.0±8.0 years) participated in at least one collision/contact sport, and 26(age=38.0±9.0 years) participated in limited/non-contact sports. Two(5%) collision/contact and 3(12%) limited/non-contact athletes had traumatic re-injury requiring revision surgery. Of the remaining athletes (59/64), minimum 5-year follow-up was obtained on 54(92%) with a mean follow-up of 12±4 years(range 5 to 23 years). All athletes returned to their original sport at the same level. There was no significant difference between collision/contact and limited/non-contact athletes in timing of return to sports (5.2±1.9 and 6.0±3.1 months, respectively; p=0.389). There were no significant differences between groups on any outcomes scores. ConclusionArthroscopic labral reconstruction with a modified inferior capsular shift addressed anterior instability with return to sport for both collision/contact and limited/non-contact athletes with excellent functional and clinical outcomes, full shoulder ROM, and a low prevalence of advanced OA at minimum 5-year follow-up. This modified technique resulted in a low failure rate in both limited/non-contact and collision/contact athletes.

Long-Term Outcomes Following Arthroscopic Labral Reconstruction with a Modified Inferior Capsular Shift for Anterior Shoulder Instability

Long-Term Outcomes Following Arthroscopic Labral Reconstruction with a Modified Inferior Capsular Shift for Anterior Shoulder Instability

Labral Pull-Through Technique for Arthroscopic Labral Reconstruction of the Hip

Background: The goal of hip labral reconstruction is to restore the suction seal, requiring the labral graft to be precisely secured along the acetabular rim. When performed arthroscopically, controlling the graft as it is suspended in the hip joint between 2 cannulas can be challenging, making fixation in the optimal position to restore the suction seal difficult to achieve. Indications: Labral reconstruction/augmentation is indicated for patients with a deficient/dysfunctional labrum when repair alone cannot restore/maintain the suction seal. Technique Description: Following diagnostic arthroscopy, debridement, and measurement of the labral deficiency (30 mm), 70 mm tibialis anterior allograft was tubularized with a whipstitch and prepared with long suture tails at both ends and a single mattress stitch placed through the graft at the medial end. Holes for the anchors were pre-drilled. Viewing from the anterolateral portal, the graft was introduced down a sled through the modified anterior portal, pulled through the joint, and guided into the posterolateral portal cannula via instrumentation through the distal anterolateral accessory portal. With initial fixation achieved medially with the mattress stitch, directing the graft into position while achieving optimal coverage of the deficient area was facilitated by the excess graft length pulled into the posterolateral portal cannula. Results: Labral reconstruction can restore the suction seal of the hip joint when repair alone is not sufficient. Comparative studies with matched repair cohorts have demonstrated comparable survivorship and patient-reported outcomes between groups, with similar rates of patient acceptable symptomatic state and minimal clinically important difference between groups, and similar rates of return to sport in high-level athletes. Recent systematic reviews have largely corroborated these findings. Discussion/Conclusions: Arthroscopic labral reconstruction is an effective treatment option when repair alone cannot restore the suction seal when the graft is secured in an optimal position, but controlling the graft during passage and fixation while achieving a final length spanning the segmental deficiency in continuity with native tissue at both ends can present technical challenges. The labral pull-through technique greatly facilitates this process.

Single Portal Segmental Labral Reconstruction of the Hip

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.

Quel est l’impact des traitements hormonaux féminins sur le système cardiovasculaire ?

To systematically review and report the mid- to long-term patient reported outcomes (PROs) following hip labral reconstruction.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.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%.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.

Graft Options for Hip Labral Reconstruction

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.

It's not arthritis! Resolution of the illusion of joint space narrowing with acetabuloplasty and labral reconstruction for the calcified labrum.

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.

Primary Arthroscopic Labral Management: Labral Repair and Complete Labral Reconstruction Both Offer Durable, Promising Results at Minimum 5-Year Follow-up

Background: Increased understanding of the acetabular labrum’s role in hip joint biomechanics has led to a greater focus on the conservation and restoration of normal labral anatomic characteristics; however, labral repair is often not possible in the setting of severe intrasubstance damage or deficiency. Purpose: To compare 5-year postoperative patient-reported outcomes between hips treated with primary complete arthroscopic labral reconstruction and those treated with primary labral repair. Study Design: Cohort study; Level of evidence, 3. Methods: All hips that underwent primary labral repair or reconstruction by the senior surgeon between January 2015 and December 2015 were included. Hips that had undergone a previous intra-articular procedure were excluded. Visual analog scales and patient-reported outcome (PRO) instruments were completed by patients within 1 week before surgery as a baseline measurement, between 22 and 26 months postoperatively for 2-year outcomes, and between 58 and 62 months for 5-year outcomes. PRO scores collected included the modified Harris Hip Score (mHHS), the 12-Item International Hip Outcome Tool, and the visual analog scale for pain and satisfaction. Pain and satisfaction were assessed using visual analog scales. Results: A total of 68 primary labral repairs and 62 primary complete labral reconstructions were included in the final analysis. Patients in the reconstruction cohort were older (38.3 vs 29.9 years; P < .001), had a higher incidence of severe labral tearing (62.90% vs 5.88%; P < .001), required a greater number of concomitant procedures (P < .001), and were more likely to have Beck grade III or IV chondral damage (12.94% vs 1.47%; P < .001). Both groups demonstrated statistically significant increases in outcome scores at minimum 5-year follow-up. Patients who underwent labral reconstruction had a significantly greater increase in mHHS from the preoperative assessment to latest follow-up compared with patients undergoing labral repair (27.43 vs 17.13; P = .04). No statistically significant differences between the 2 cohorts were found in achievement of minimal clinically important difference, Patient Acceptable Symptom State, maximum outcome improvement, and substantial clinical benefit at latest follow-up (P > .05). In total, 2 patients in the repair cohort and 3 patients in the reconstruction cohort required revision arthroscopy (P = .574). Further, 1 patient from each group converted to arthroplasty (P = .947). Conclusion: The results of this study suggest that primary complete labral reconstruction is a viable surgical option for hips with moderate to severe labral pathology. At minimum 5-year follow-up, labral reconstruction produced similar outcomes to labral repair despite less favorable preoperative patient characteristics in the reconstruction cohort.

Comparison of Acetabular Labral Reconstruction With 7-mm Tibialis Anterior Allograft and 5-mm Iliotibial Band Autograft at Minimum 2-Year Follow-up

Background: Labral reconstruction has been described as a treatment option for irreparable labral tear. Labral graft size ranges from 5 to 7 mm2 for reconstruction. A thicker labral graft could support mechanical stability and protect cartilage better. No study has compared the effect of graft thickness on clinical outcomes. Purpose/Hypothesis: The purpose of this study was to compare patient-reported outcomes between hips reconstructed with an autologous iliotibial band (AUITB; 5 mm2) graft and with an allogenic tibialis anterior (ALTA; 7 mm2) tendon graft. Our hypothesis was that hips reconstructed with a thicker allograft (7 mm2) would have better clinical outcomes than those with a smaller autograft (5 mm2). Study Design: Cohort study; Level of evidence, 2. Methods: A total of 42 patients (aged 21 to 54 years) underwent arthroscopic hip segmental labral reconstruction during the study period of January 2016 to November 2018. Twenty patients had reconstruction with AUITB grafts (5 mm2) and 22 with ALTA grafts (7 mm2). Both groups had minimum 2 year follow-up. Patients were evaluated with patient-related outcome scores: modified Harris Hip Score, Nonarthritic Hip Score, and Hip Outcome Score–Sports Specific. Pain evaluation was performed using a visual analog scale. Results: There were significant differences in all studied variables when comparing pre- and postoperative scores. Yet, there were no differences in terms of patient-related outcome scores between the groups postoperatively. Postoperative visual analog scale scores averaged 2.1 for the AUITB group vs 1.9 for the ALTA group (P = .89); modified Harris Hip Score, 82.7 vs 83.3 (P = .77); Nonarthritic Hip Score, 81.1 vs 82.2 (P = .81); and Hip Outcome Score–Sports Specific, 81.6 vs 82.5 (P = .67). Conclusion: No differences were found in terms of clinical outcomes between the 7-mm2 ALTA graft and the 5-mm2 AUITB graft. Both graft types and thicknesses might be considered comparable choices for primary reconstruction. Although a thicker-graft labral reconstruction seemed to have more ability to cover joint surface, clinical results did not show any superiority of a thicker graft whether it is autologous or allogenic.

Allograft Labral Reconstruction of the Hip: Expanding Evidence Supporting Greater Utilization in Hip Arthroscopy.

Purpose of ReviewThe 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 FindingsNumerous 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.SummaryArthroscopic 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

Effect of Cigarette Smoking on Outcomes in Patients Undergoing Primary Hip Arthroscopy and Labral Reconstruction: A Propensity-Matched Controlled Study With Minimum 2-Year Follow-up.

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

Postoperative Doxycycline Did Not Improve Early Postoperative Outcomes in Hip Arthroscopy Patients: A Retrospective Cohort Study

AbstractDoxycycline has been shown to reduce fibroblast activity in the treatment of multiple pathologies, and was utilized as part of the postoperative medication protocol to help prevent adhesions from developing after hip arthroscopy. The purpose of this study was to compare early postoperative pain outcomes between consecutive case series of femoroacetabular impingement syndrome (FAIS) patients treated with or without a 7-day postoperative course of doxycycline following hip arthroscopy. We hypothesized that the doxycycline-treated group would have superior patient-reported outcomes at 6 weeks, and the effect would be more pronounced for patients with low preoperative mental health scores.Our institutional review board–approved prospective outcomes registry was queried for patients who had undergone arthroscopic femoral osteochondroplasty and/or labral repair or reconstruction secondary to FAIS performed by a single, fellowship-trained surgeon. A 7-day postoperative course of doxycycline was initiated in 2018. Six-week postoperative Hip Disability and Osteoarthritis Outcome Score (HOOS) global (HOOSglobal) and International Hip Outcome Tool (iHOT) scores were compared between the consecutive series treated with versus without doxycycline. Additional subgroup analysis was performed on patients with low preoperative Veterans RAND 12-Item Health Survey (VR-12) mental component scores to determine possible additional benefit of postoperative doxycycline in this group.A total of 134 patients (98 female, 36 male, age = 36.2 ± 13.4 years, body mass index [BMI] = 27.2 ± 5 kg/m2) were identified between 2013 and 2020. There were no differences between the control (n = 84) and doxycycline group (n = 50) in age, sex, or BMI. Postoperative HOOSglobal scores (control = 58.5 ± 13.1, doxycycline = 58.7 ± 14.7, p = 0.96) and iHOT scores (control = 54.4 ± 22.2, doxycycline = 52.3 ± 24.8, p = 0.61) did not differ between groups. The subset of 83 patients with low preoperative mental scores showed no differences in HOOSglobal (control = 51.6 ± 13.3, doxycycline = 57.3 ± 7.4, p = 0.12) or iHOT scores (control = 45.5 ± 20.3, doxycycline = 53.6 ± 23.1, p = 0.250).Our results do not support the hypothesis that postoperative doxycycline leads to significant improvement in early postoperative pain scores or functional outcomes in patients undergoing hip arthroscopy for FAIS.

Minimum 2-Year Outcomes Following Arthroscopic Hip Labral Reconstruction in Adolescents and Young Adults.

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. 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. 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. 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 IV, case-series.

Circumferential and Segmental Labral Reconstruction: A Systematic Review

The purposes of this study were to synthesize, report, and compare patient-reported outcomes (PROs) between arthroscopic segmental and circumferential labral reconstruction. A systematic review was performed in February 2019 using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) method. Inclusion criteria were levels I to IV evidence, articles in English, arthroscopic labral reconstruction, and PROs data. Exclusion criteria were labral treatment without reconstruction, open surgery, and less than 6-month follow-up. Eleven studies were identified. Nine studies (212 hips) reported outcomes of segmental reconstruction. Two studies (194 hips) reported outcomes of circumferential reconstruction. Significant improvement in PROs at short-term with either segmental or circumferential reconstruction was found. [Orthopedics. 2021;44(6):361-366.].

Circumferential and Segmental Arthroscopic Labral Reconstruction of the Hip Utilizing the Knotless Pull-Through Technique with All-Suture Anchors

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.
