Abstract
BACKGROUND The capsular ligaments at the hip joint work in synchrony with the acetabulum and femoral head for articular stability. There is a lack of understanding about ischiofemoral ligament (ISFL) anatomy and function. PURPOSE To assess the insertion of the ISFL in non-arthritic adult hips. MATERIAL AND METHODS A retrospective analysis was performed in 72 patients who underwent magnetic resonance arthrogram (MRA) for the assessment of hip pain. The distribution of the ISFL components, the thickness, and the insertion site were assessed by concomitantly using the axial oblique, coronal, and sagittal MRA images. RESULTS Two insertions of the ISFL anterior to the center of the femoral head were identified in 71 (99%) hips: (i) predominant anterior merging with the iliofemoral ligament as continuation of zona orbicularis, observed in all hips; and (ii) anterolateral junction of femoral neck and greater trochanter. Two ISFL parts (proximal and distal) were identified in 70 (97%) of the 72 studied hips. The proximal part was always thinner (mean 2.6 ± 0.7 mm) and originated from the ischium at the acetabular rim. The distal part was a continuation of the zona orbicularis, and the mean thickness was 6.7 ± 1.6 mm. Both parts merged as they coursed over the superior portion of the femoral head. CONCLUSION The predominant insertion of the ischiofemoral ligament is a merging to the iliofemoral ligament anteriorly. Surgical procedures such as hip arthroscopy involving the ISFL will affect the function of the iliofemoral ligament, and vice versa.

Orthop J Sports Med 2024; 12:23259671241251413. [PMID: 38831873 PMCID: PMC11144363 DOI: 10.1177/23259671241251413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 11/14/2023] [Indexed: 06/05/2024] Open
Abstract
Background Many recent studies have shown that patients who undergo capsular repair after hip arthroscopy achieve superior clinical outcomes compared with those who do not. However, patients with dysplasia or generalized ligamentous laxity (GLL) were not excluded from most of these studies, which may have affected the outcomes. Purpose To determine whether capsular repair influences the outcomes of hip arthroscopy for patients without dysplasia or GLL. Study Design Systematic review; Level of evidence, 1. Methods Under the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, randomized controlled trials comparing the outcomes of capsulotomy with versus without repair were included, but studies that included patients with dysplasia or GLL were excluded. The study outcomes were patient-reported outcome measures (PROMs) at 6 months and 2 years postoperatively-including the modified Harris Hip Score (mHHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), and Hip Outcome Score-Sport-Specific Subscale (HOS-SSS)- and were compared between the repair and no-repair groups. A narrative analysis and meta-analysis were performed to integrate and compare the results of the 2 groups. In the meta-analysis of the outcome measures, studies with significant differences in the preoperative scores between the repair and no-repair groups were excluded because previous studies have shown that these can affect the outcomes. Results A total of 761 studies were initially identified, of which 3 were included. Of the 322 included patients, 136 underwent capsular repair, and 186 underwent capsulotomy with no repair. The meta-analysis showed that capsular repair was associated with significantly higher postoperative PROMs: the mHHS at 2 years (P = .03), the HOS-ADL at 6 months (P = .02) and 2 years (P < .0001), and the HOS-SSS at 6 months (P = .02) and 2 years (P = .001). Conclusion Capsular repair after hip arthroscopy was associated with superior clinical outcomes when compared with no capsular repair in patients without dysplasia or GLL.

Abstract
Background A number of techniques have been described to enter the capsule and gain access to the hip joint during hip arthroscopy1,2. Among these, the interportal and T-capsulotomies are the most commonly utilized; however, these approaches transect the iliofemoral ligament, which normally resists anterior subluxation and stabilizes extension3. Thus, these approaches may introduce capsuloligamentous instability1,4-7 and have been associated with complications such as dislocation, postoperative pain, microinstability, seroma, and heterotopic ossification5,8-12. Although prior literature has demonstrated durable mid-term results for patients undergoing capsulotomies with capsular closure6,13, avoidance of iatrogenic injury to the hip capsule altogether is preferable. Thus, the puncture capsulotomy technique we present is minimally invasive, preserves the biomechanics of the hip joint and capsule without disrupting the iliofemoral ligament, and allows for appropriate visualization of the joint through placement of multiple small portals. Description Following induction of anesthesia and with the patient supine on a hip traction table, the nonoperative leg is positioned at 45° abduction with support of a well-padded perineal post, and the operative hip is placed into valgus against the post14. Intra-articular fluid distention with normal saline solution is utilized to achieve approximately 9 mm of inferior migration of the femoral head and decrease risk of iatrogenic nerve injury15. Then, under fluoroscopic guidance, an anterolateral portal is created 1 cm anterior and 1 cm superior to the greater trochanter at an approximately 15° to 20° angle. Second, via arthroscopic visualization, the anterior portal is created 1 cm distal and 1 cm lateral to the intersection of a vertical line drawn at the anterior superior iliac spine and a horizontal line at the level of the anterolateral portal. Third, equidistant between the anterior and anterolateral portals, the mid-anterior portal is created distally. Finally, at one-third of the distance between the anterior superior iliac spine and the anterolateral portal, the Dienst portal is created. Thus, these 4 portals form a quadrilateral arrangement through which puncture capsulotomy can be performed5. Alternatives Alternative approaches to the hip capsule include interportal and T-capsulotomies, with or without capsular closure1,2,4,6,7,16. Although the most frequently utilized, these approaches transect the iliofemoral ligament and thus may introduce capsuloligamentous instability1,4-7,17. Rationale The puncture capsulotomy technique has the advantage of maintaining the integrity of the capsule through the placement of 4 small portals. The technique does not transect the iliofemoral ligament and thus does not introduce capsuloligamentous instability. Furthermore, although good mid-term outcomes have been reported with capsular closure6,13,18, the present technique avoids creating unnecessary injury to the capsule and complications of an unrepaired capsule or, conversely, of plication. Expected Outcomes Patients who underwent the puncture capsulotomy technique showed significant improvements in multiple functional outcome scores at a mean follow-up of 30.4 months, including the International Hip Outcome Tool (iHOT-33) (39.6 preoperatively to 76.1 postoperatively), Hip Outcome Score-Activities of Daily Living subscale (HOS-ADL) (70.0 to 89.3), HOS Sport-Specific Subscale (HOS-SSS) (41.8 to 75.7), and modified Harris hip score (mHHS) (60.1 to 84.9). At 2 years postoperatively with respect to iHOT-33, 81.0% of patients achieved the minimal clinically important difference, 62.0% achieved the patient acceptable symptom state, and 58.9% achieved substantial clinical benefit. In addition, mean visual analog scale pain scores improved significantly over the follow-up period (6.3 to 2.2; p < 0.001). Finally, there were zero occurrences of infection, osteonecrosis of the femoral head, dislocation or instability, or femoral neck fracture in patients treated with puncture capsulotomy19,20. Important Tips Anterolateral portal placement should be performed using the intra-articular fluid distention technique with fluoroscopy to avoid risk of iatrogenic labral damage and distraction-induced neurapraxia. Subsequent portals must then be placed under direct arthroscopic visualization.On establishment of the anterolateral portal, the scope should be switched to the anterior portal to ensure that the anterolateral portal has not been placed through the labrum and to adjust its placement to better access pathology. This portal, as well as all others, may be subsequently modified by adjusting the angle of the cannula, without making a new skin incision.If a cam lesion is located more anteromedially or posterolaterally, an additional accessory portal may be made distal or proximal to the anterolateral portal, respectively, in order to enhance visualization.Intermittent traction is utilized throughout the surgery. No traction is utilized during preparing and draping, suture tensioning and tie-down, and femoroplasty, with minimal traction during acetabuloplasty; these precautions serve to prevent iatrogenic superficial peroneal nerve injury.There can be a steep learning curve for this technique. In particular, greater surgical experience is required to perform adequate femoral osteoplasty for large cam lesions with this approach21.Instrument maneuverability and visualization can be somewhat constrained with this approach.It is more difficult to perform certain procedures with this technique, including segmental and circumferential labral reconstructions, particularly with remote grafts5.

Abstract
The hip capsule consists of the iliofemoral, ischiofemoral, and pubfemoral ligaments. The iliofemoral ligament is an important part of the anterior hip capsule that functions to stabilize the joint but is commonly incised in order to obtain access during hip arthroscopy, as described in techniques such as interportal, T, puncture, and periportal capsulotomy. For the most commonly used interportal capsulotomy, recent literature has advocated for closure of the capsule at the end of the surgery to avoid iatrogenic instability or microinstability. Systematic reviews and cohort studies have reported significantly better patient-reported outcomes after hip arthroscopy for femoroacetabular impingement syndrome with capsule closure compared to without capsule closure. However, recent high-level evidence from a randomized controlled trial demonstrated that in a predominantly male cohort there was no difference in patient-reported outcomes improvements or complications between patients undergoing hip arthroscopy for femoroacetabular impingement syndrome through an interportal capsulotomy who were randomized to receive capsule closure versus no capsule closure. Of note, male patients have inherently tighter and more stable joints than female patients and therefore are at lower risk for postoperative instability or microinstability from an interportal capsulotomy that does not properly heal. Also, if the capsule is not violated below the 3-o'clock position (for a right hip, or 9 o'clock for a left hip), there may be less risk to destabilizing the hip joint. A limited interportal capsulotomy in male patients could lead to healing in an unrepaired state.

Abstract
PURPOSE OF REVIEW Hip arthroscopy is widely used for the management of intra-articular pathology and there has been growing interest in strategies for management of the hip capsule during surgery. The hip capsule is an essential structure that provides stability to the joint and it is necessarily violated during procedures that address intra-articular pathology. This article reviews different approaches to capsular management during hip arthroscopy including anatomical considerations for capsulotomy, techniques, clinical outcomes, and the role of routine capsular repair. This article also reviews the concept of hip microinstability and its potential impact on capsular management options as well as iatrogenic complications that can occur as a result of poor capsular management. RECENT FINDINGS Current research highlights the key functional role of the hip capsule and the importance of preserving its anatomy during surgery. Capsulotomies that involve less tissue violation (periportal and puncture-type approaches) do not appear to require routine capsular repair to achieve good outcomes. Many studies have investigated the role of capsular repair following more extensive capsulotomy types (interportal and T-type), with most authors reporting superior outcomes with routine capsular repair. Strategies for capsular management during hip arthroscopy range from conservative capsulotomy techniques aimed to minimize capsular violation to more extensive capsulotomies with routine capsule closure, all of which have good short- to mid-term outcomes. There is a growing trend towards decreasing iatrogenic capsular tissue injury when possible and fully repairing the capsule when larger capsulotomies are utilized. Future research may reveal that patients with microinstability may require a more specific approach to capsular management.

Abstract
Background There is concern for maintaining the integrity of the reflected head of the rectus femoris during arthroscopic hip joint access. Because of the proximity to the indirect head of the rectus femoris (IHRF), capsulotomy technique and capsular closure during routine hip arthroscopy may play a role in postoperative tendinitis. Purpose To quantify the extent of injury sustained to the IHRF during interportal versus periportal capsulotomy for routine arthroscopic hip joint access. Study Design Controlled laboratory study. Methods A cadaveric study was conducted using 20 fresh-frozen cadaveric hips, in which hip joint access through a periportal capsulotomy (n = 10) or interportal capsulotomy (n = 10) was performed. Capsular closure followed by a layered dissection to the capsuloligamentous complex of the hip joint was then performed to localize the IHRF. Suture proximity to the tendon, tendon disruption, and the IHRF footprint was documented to the nearest 0.01 mm using digital calipers. Statistical analysis was performed using unpaired Student t tests. Results The mean capsulotomy length for the interportal specimens was 19.27 ± 3.25 mm, and the mean medial and lateral capsulotomy length for the periportal specimens was 4.47 ± 1.60 and 4.26 ± 0.89 mm, respectively. There was violation of the tendon in 3 of 10 interportal specimens and 4 of 10 periportal specimens. There was no significant difference in the closest suture measured to the IHRF for specimens with versus without tendon violation, for either interportal or periportal capsulotomy. Conclusion We found comparable outcomes with regard to violation of the IHRF between interportal and periportal capsulotomy, with no significant difference in suture proximity to the IHRF in specimens with or without tendon violation. There remains no consensus on the ideal method by which to avoid iatrogenic damage to the IHRF. Clinical Relevance Our findings provide insight that may lead to future advances in surgical care, such that protection of the tendon during routine hip arthroscopy may allow for improved postoperative rehabilitation and strength.

Abstract
BACKGROUND Femoro-acetabular impingement syndrome (FAIS) is a common cause of hip pain and functional decline. The quality of life of affected patients has been shown to be significantly diminished, with potential alterations in the ability to perform activities of daily living and recreation, including sexual function. Hip arthroscopy is the surgical technique recognized as the gold standard in FAIS. The aim of this study was to research the relationship between hip arthroscopy due to FAIS and pre- and postoperative sexual function. HYPOTHESIS The hypothesis of the study was that sexual dysfunction would be common during the preoperative period but would significantly improve after surgery. MATERIALS AND METHODS This retrospective study included 96 patients aged 18 to 55 years, who underwent hip arthroscopy for a FAIS diagnosis between 2015 and 2021, with a minimum follow-up of one year. Exclusion criteria were a bilateral symptomatic hip condition, history of ipsilateral hip or knee surgery, history of urological or gynecological conditions, sexual dysfunction, or a history of hip osteonecrosis or osteoarthritis. The Female Sexual Function Scale (FSFI) was used to evaluate sexual dysfunction in females and the International Erectile Function Index (IIEF-5) for males. RESULTS The patients comprised 56.3% males and 43.82% females with a mean age of 35.3±8.3 years. Sexual dysfunction was determined preoperatively in 85.2% of the males and in 57.1% of the females. Overall improvement after surgery was statistically significant. Signs of pudendal nerve damage were seen during the postoperative period in 29 (30.2%) patients. The change in total sexual scores was significantly correlated with nerve symptoms and regression analysis showed that traction time was a significant risk factor for pudendal nerve symptoms. DISCUSSION Sexual dysfunction is a common trait of patients suffering from FAIS and the majority of patients significantly benefit from the procedure. Sexual dysfunction persists in a category of patients during the postoperative period, regardless of the type of lesion, and this phenomenon is associated with transient pudendal nerve symptoms, which are more likely to occur with longer traction times and thus represent a clear risk factor.

Abstract
PURPOSE To assess the 2-year outcomes of arthroscopic treatment with periportal capsulotomy closure for femoroacetabular impingement syndrome (FAIS) in patients with generalized ligamentous laxity (GLL). METHODS A retrospective analysis was performed from a prospectively collected database of FAIS patients undergoing hip arthroscopy. FAIS patients with GLL were identified as having Beighton score ≥4. FAIS patients with GLL were treated with arthroscopic labral repair, osteochondroplasty, via periportal capsulotomy with subsequent capsular closure. These patients were matched by age, sex, and body mass index (BMI) with a cohort of FAIS patients without GLL who underwent the same procedure via periportal capsulotomy without capsular closure. Preoperatively, and 2 years postoperatively, patients completed patient-reported outcomes (PRO) scores, including the Hip Disability and Osteoarthritis Outcome Score (HOOS), 12-item Short-Form survey (SF-12) and the visual analog scale (VAS). RESULTS Forty patients (5 male, 35 female) with FAIS and GLL were included (age: 29.7 ± 9.0; BMI: 23.3 ± 4.1). FAIS patients with GLL demonstrated similar significant PRO score improvements compared to a matched cohort of FAIS patients without GLL at 2 years after surgery (VAS Pain: (-)2.5 ± 3.0, (-)2.7 ± 2.7; SF-12 PCS: 17.7 ± 14.2, 16.7 ± 15.0; HOOS-Symptoms: 26.3 ± 24.0, 20.6 ± 18.1; HOOS-Pain: 29.8 ± 20.4, 24.4 ± 9.0; HOOS-ADL: 24.9 ± 18.4, 22.0 ± 19.9; HOOS-Sports: 43.6 ± 26.1, 33.1 ± 29.8; and HOOS-QOL: 44.2 ± 27.6, 41.7 ± 27.1, respectively). Both cohorts achieved minimal clinically important differences (MCID) for each HOOS subscore at equivalent high rates (70-88%). CONCLUSIONS Patients with GLL in the setting of FAIS can be effectively treated with arthroscopy via periportal capsulotomy and capsular closure. These patients demonstrate significant improvements in PRO scores at 2 years, similar to normal laxity FAIS patients undergoing arthroscopic treatment via periportal capsulotomy without capsular closure. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

Abstract
Management of the hip capsule remains an ongoing discussion in the field of hip arthroscopy. Interportal and T-capsulotomies remain the most common approaches to gain access to the hip during surgery, and biomechanical and clinical research supports repair of these types of capsulotomies. Less is known, however, about the quality of the tissue that heals at these repair sites during the postoperative period, particularly in the setting of patients with borderline hip dysplasia. The capsular tissue provides important joint stability to these patients, and disruption to the capsule can result in significant functional impairments. There is also an association between borderline hip dysplasia and joint hypermobility, which increases the risk of insufficient healing after capsular repair. Patients with borderline hip dysplasia show poor capsular healing after arthroscopy followed by interportal hip capsule repair, and incomplete healing results in inferior patient-reported outcomes. Periportal capsulotomy may limit capsular violation and improve outcomes.

[PMID: 37146665 DOI: 10.1016/j.arthro.2023.04.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 04/19/2023] [Accepted: 04/20/2023] [Indexed: 05/07/2023]
Abstract
PURPOSE The purpose of this study was to perform a systematic review of studies reporting on minimum 5-year outcomes of patients undergoing primary hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) to determine whether capsular management influences patient-reported outcomes (PROs), rates of clinically significant outcome, and rates of revision surgery or conversion to total hip arthroplasty (THA). METHODS PubMed, Scopus, and Google Scholar were searched around the terms hip arthroscopy, FAIS, five-year follow-up, and capsule management. Articles available in English, presenting original data, and reporting minimum 5-year follow-up after HA using either PROs or conversion to THA and/or revision surgery were included. Quality assessment was completed using MINORS assessment. Articles were stratified into unrepaired and repaired capsule cohorts (excluding periportal capsulotomy techniques). RESULTS Eight articles were included. MINORS assessment ranged from 11-22, with excellent (k=0.842) inter-rater reliability. Populations without capsular repair were identified in four studies including a total of 387 patients, at an age of 33.1-38.0 years and follow-up range of 60.0-77 months. Populations with capsular repair were identified in five studies including a total of 835 patients, at an age range of 33.6-43.1 years and follow-up range of 60.0-78.0 months. All studies included PROs and all reported significant improvement (p<0.05) at the 5-year timepoint, with modified Harris Hip Score (mHHS) being the most frequent (n=6). No differences were noted between groups regarding any of the measured PROs. Average rates of achieving MCID and PASS for mHHS were similar between patients without capsular repair (MCID 71.1%, PASS 73.7%, n=1) and with capsular repair (MCID 66.0%-90.6%, PASS 55.3%-87.4%, n=4). Conversion to THA occurred in 12.8-18.5% and 0.0-29.0% for patients with an unrepaired and repaired capsule, respectively. Revision HA occurred in 15.4-25.5% and 3.1-15.4% in unrepaired and repaired capsular patients, respectively. CONCLUSIONS Patients undergoing hip arthroscopy for FAI had significant improvement in PRO scores at minimum 5-year follow-up, and scores did not differ between patients that underwent capsular repair and those that did not. Similar rates of markers of clinical benefit and THA conversion were achieved by both groups; however, lower rates of revision hip arthroscopy were demonstrated in the capsular repair cohort.

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 most common surgical approaches in hip arthroscopy are interportal and T-capsulotomy. However, these methods may introduce capsular instability. Puncture capsulotomy preserves capsuloligamentous integrity by avoiding iatrogenic transection of the iliofemoral capsular ligament. Purpose To present minimum 2-year functional outcomes for patients who underwent arthroscopic treatment for acetabular labral tears and concomitant femoroacetabular impingement using the puncture capsulotomy technique. Study Design Case series; Level of evidence, 4. Methods The authors conducted a retrospective review of prospectively collected data on patients who underwent arthroscopic acetabular labral tear treatment between December 2013 and May 2019. Included were patients aged ≥18 years who underwent hip arthroscopy by a single surgeon and completed a minimum of 2 years of patient-reported outcome measure (PROM) surveys. Intraoperatively, patients underwent hip arthroscopy via puncture capsulotomy to treat labral tears and any concomitant femoroacetabular impingement. Clinical outcome data consisted of PROMs. Results A total of 163 hips were included; the mean patient follow-up was 30.4 months (range, 24-60 months; 95% CI, 28.5-32.3 months). Patients had a mean age of 37.9 years (range, 36.1-39.6 years), with a mean body mass index of 25.9 (range, 25.2-26.5). There were significant improvements in mean [95% CI] baseline to final follow-up scores for the 33-Item International Hip Outcome Tool (iHOT-33) (39.6 [36.8-42.4] vs 76.1 [72.7-79.6]), Hip Outcome Score-Activities of Daily Living (70.0 [67.0-73.0] vs 89.3 [87.3-91.3]), modified Harris Hip Score (60.1 [57.9-62.4] vs 84.9 [82.5-87.2]), and Hip Outcome Score-Sports Specific Subscale (41.8 [37.9-45.6] vs 75.7 [71.7-79.7]) (P < .001 for all). Additionally, the mean [95% CI] visual analog scale pain scores were noted to significantly improve throughout the duration of the postoperative period (from 6.3 [5.9-6.7] to 2.2 [1.8-2.6]; P < .001). There were no incidences of infection, avascular necrosis of the femoral head, dislocation/instability, or femoral neck fracture. At the 2-year follow-up, 81.0%, 62.0%, and 58.9% of hips achieved previously published clinically meaningful iHOT-33 thresholds for minimally clinically important difference, Patient Acceptable Symptom Score, and substantial clinical benefit, respectively. Conclusion Puncture capsulotomy demonstrated significantly improved functional and clinically meaningful outcomes at a minimum 2-year follow-up, along with a minimal complication rate.

Comparable Torque to Failure Using the Simple Stich Versus the Figure-of-Eight Configuration for Hip Capsular Closure Following an Interportal Capsulotomy: A Cadaveric Study. Arthroscopy 2022; 38:3143-3148. [PMID: 35750245 DOI: 10.1016/j.arthro.2022.05.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2022] [Revised: 04/23/2022] [Accepted: 05/31/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To measure and compare the torque to failure and stiffness of the capsular repair construct consisting of four-suture simple stitches to a two-figure of eight stitches repair construct in external rotation following an interportal capsulotomy. METHODS Six pairs of fresh-frozen cadaveric hemipelves were divided into two capsular repair groups. All hips underwent a 40-mm interportal capsulotomy from the 12 o'clock position to the 3 o'clock position. Capsular closure was performed using either the two stitches in a figure of eight or with four simple stitches. Afterward, each hemipelvis was securely fixed to the frame of a mechanical testing system with the hip in 10° of extension and externally rotated to failure. Significance was set at P < .05. RESULTS The average failure torque was 86.2 ± 18.9 N·m and 81.5 ± 8.9 N·m (P = .57) for the two stitches in a figure of eight and the four simple stitches, respectively. Failure stiffness was also not statistically different between groups and both capsular closure techniques failed at similar degrees of rotation (P = .65). CONCLUSION Hip capsular repair using either the four simple stitch or two-figure of eight configurations following interportal capsulotomy demonstrated comparable failure torques and similar stiffness in a cadaveric model. CLINICAL RELEVANCE Adequate and comprehensive capsular management in hip arthroscopy is critical. Capsular repair following capsulotomy in femoroacetabular impingement surgery has been associated with higher patient-reported outcomes when compared to capsulotomy without repair. Therefore, determining which capsular closure construct provides the higher failure torque is important.

Patient-Reported Outcome Surveys for Femoroacetabular Impingement Syndrome Demonstrate Strong Correlations, High Minimum Clinically Important Difference Agreement and Large Ceiling Effects. Arthroscopy 2022; 38:2829-2836. [PMID: 35367302 DOI: 10.1016/j.arthro.2022.03.023] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 03/05/2022] [Accepted: 03/07/2022] [Indexed: 02/02/2023]
Abstract
PURPOSE To determine the correlation between different patient-reported outcome (PRO) measurements used to assess outcomes after arthroscopic treatment of femoroacetabular impingement syndrome (FAIS) in a single cohort of patients. METHODS Patients undergoing primary hip arthroscopy for FAIS (without dysplasia, arthritis, or joint hypermobility) were retrospectively analyzed from a prospectively collected cohort. PROs collected before surgery and at 2-year follow-up included the Visual Analog Scale (VAS) for pain, modified Harris Hip Score (mHHS), Hip Disability and Osteoarthritis Outcome Scores (HOOS) with subscales for symptoms, pain, activities of daily living (ADL), sport, and quality of life (QoL), and the physical and mental components of the Short Form-12 (SF-12 PCS and SF-12 MCS). RESULTS Three hundred patients with 2 years' follow-up (mean age 35.1 ± 11.3, BMI 24.7 ± 3.8, 52.7% female, median Tönnis grade 1) were identified. All patients underwent femoroplasty and labral repair. There was a strong correlation among nearly all the PRO surveys at 2-year follow-up, with the highest correlations identified between mHHS and HOOS-Pain (r = .86, P < .001) and mHHS and HOOS-ADL (r = .85, P < .001). Preoperative scores and the change from preoperative to postoperative scores demonstrated an overall moderate correlation between surveys. There was a consistently weak correlation between the SF-12 MCS and all other PROs. There were strong agreements (67%-77%) in the patients achieving minimal clinically important differences (MCID) for each PRO survey. All surveys except the SF-12 demonstrated a ceiling effect after surgery, with 13% to 43% of patients achieving the maximum score. CONCLUSIONS PRO surveys used for FAIS demonstrate strong correlations, especially in the evaluation of patients during the postoperative period. MCID for VAS, mHHS, and HOOS demonstrate strong agreement, whereas large ceiling effects were seen with the mHHS and HOOS. The results support a more efficient use of PRO scores while being able to accurately capture patient outcomes. LEVEL OF EVIDENCE IV, retrospective case series.

Abstract
Background Postoperative biomechanics after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) are an outcome of interest, but correlation with patient-reported outcomes (PROs) remains unclear. Purpose/Hypothesis The purpose of this study was to assess the correlation between changes in hip biomechanics in FAIS patients after hip arthroscopy and changes in PRO scores. We hypothesized that gait analysis would demonstrate significant correlations between pre- and postoperative changes in biomechanics and changes in PRO scores. Study Design Descriptive laboratory study. Methods FAIS patients without dysplasia or arthritis who underwent primary hip arthroscopy for labral repair and femoroplasty underwent preoperative and 1-year postoperative 3-dimensional motion tracking and biomechanical testing during normal gait. Joint kinematics calculated included flexion/extension (sagittal plane), abduction/adduction (frontal plane), and internal/external rotation (transverse plane). Peak hip angles and moments were compared between baseline and 1-year postoperative measures. At baseline, 1-year, and 2-year postoperatively, patients completed the following PRO surveys: 12-Item Short Form Health Survey (SF-12), modified Harris Hip Score (mHHS), and Hip disability and Osteoarthritis Outcome Score (HOOS). Joint kinematics that significantly improved 1 year after surgery were assessed for correlations with PRO scores. Results A total of 10 patients (12 hips) were enrolled prospectively. PROs significantly improved at 1 and 2 years postoperatively compared with baseline values for HOOS, mHHS, and SF-12 Physical Component Score, with all patients achieving the minimal clinically important difference (MCID) on the HOOS Sport/Recreation and Quality of Life subscales. From preoperatively to 1-year postoperatively, significant improvements were seen in peak hip abduction angle (from -2.3° ± 1.8° to -4.6° ± 1.8°; P = .0058) and peak hip extension moment (from -1.03 ± 0.19 to -0.85 ± 0.20 N·m/kg; P = .014); however, there were no significant correlations between these changes and the pre- to postoperative changes on any PRO scores. Conclusion Gait analysis of FAIS patients after hip arthroscopy demonstrated small, albeit significant, changes in postoperative hip kinetics and kinematics; however, these changes did not correlate with the large, clinically significant improvements in PROs at 1 year after surgery. Clinical Relevance The results of this study suggest that the degree of improvement in short-term PROs after hip arthroscopy for FAIS may not be related to small changes in biomechanics postoperatively.

Abstract
PURPOSE The purpose of this review is to provide a summary of the techniques and outcomes of various capsular management strategies in patients undergoing hip arthroscopy for femoroacetabular impingement (FAI). The information this review provides on capsular management strategies will provide surgeons with operative guidance and decision-making when managing patients with FAI lesions arthroscopically. METHODS Three databases MEDLINE, EMBASE, and PubMed were searched from database inception to November 2nd 2021, for literature addressing capsular management of patients undergoing hip arthroscopy for FAI. All level I-IV data on capsular management strategy as well as postoperative functional outcomes were recorded. A meta-analysis was used to combine the mean postoperative functional outcomes using a random-effects model. RESULTS Overall, there were a total of 36 studies and 4744 patients included in this review. The mean MINORS score was 10.7 (range 8-13) for non-comparative studies and 17.6 (range 15-20) for comparative studies. Three comparative studies in 1302 patients examining the proportion of patients reaching the MCID for the mHHS score in patients undergoing interportal capsulotomy with either capsular repair or no repair found that the capsular repair group had a higher odds ratio of reaching the MCID at 1.46 (95% CI 0.61-3.45, I2 = 67%, Fig. 2, Table 3); however, this difference was not significant with a p value of 0.39. When looking at only level 1 and 2 studies, four studies in 1308 patients reporting on the mHHS score in patients undergoing capsular closure regardless of capsulotomy type, found a pooled standardized mean difference in the mHHS score of 2.1 (95% CI 1.7-2.55, I2 = 70%, Fig. 3), while four studies in 402 patients reporting on the mHHS score in patients not undergoing capsular closure regardless of capsulotomy type found a pooled standardized mean difference in the mHHS score of 1.46 (95% CI 1.2-1.7, I2 = 30%, Fig. 4). CONCLUSION This review may demonstrate improved postoperative outcomes in patients undergoing complete capsular closure regardless of capsulotomy type based on postoperative mHHS score. Furthermore, this review may suggest improved postoperative outcomes after closure of an interportal capsulotomy. There are limited published outcome data regarding T-type capsulotomy without closure. This review provides surgeons with operative guidance on capsular management strategies when treating patients with FAI lesions arthroscopically. LEVEL OF EVIDENCE IV.

Capsule Closure of Periportal Capsulotomy for Hip Arthroscopy. Arthrosc Tech 2022; 11:e1117-e1122.

Abstract
Multiple approaches for management of the hip capsule during hip arthroscopy for femoroacetabular impingement syndrome have been reported. Capsular closure is advocated in the setting of larger capsulotomies, including interportal and T-capsulotomies, to reduce the risk of iatrogenic instability or microinstability of the hip. The periportal capsulotomy technique has been described for conservative management of the capsule that would not necessitate closure. However, hip arthroscopy for patients with ligamentous laxity or joint hypermobility may warrant capsule closure or plication even with use of conservative capsulotomy techniques. We introduce a technique for closure of periportal capsulotomy as a means to repair or plicate the hip capsule in the at-risk hypermobile patient.

Abstract
Background Hip arthroscopy for treatment of femoroacetabular impingement (FAI) has developed rapidly and has been shown to significantly decrease pain and improve hip function. However, the relationship between hip capsule characteristics and healing after arthroscopic surgery and changes in patient-reported outcomes scores (PROs) for postoperative pain, function, and symptoms is still uncertain. Methods We retrospectively evaluated consecutive patients who were diagnosed with FAI and underwent hip arthroscopy for treatment in our hospital between May 2018 and November 2020. All patients had preoperative MRI and postoperative MRI at least 6 months after arthroscopy. Hip capsular thickness was measured at the proximal, middle, and distal site of the capsule. PROs and PROs at final follow-up were obtained, including visual analog scale (VAS) for pain and modified Harris Hip Score (mHHS). Results A total of 194 patients were included in this study. The mean MRI follow-up time was 14.3 (range, 6–37) months, and the mean clinical follow-up time was 26.1 (range, 12–43) months. Postoperative capsular thickness or net change were not correlated with postoperative PROs and VAS (P > .05). Capsular defect was observed in 17 (8.8%) patients. Patients with capsular defect had a relatively higher BMI (P < .05). Patients with capsular defect had a significant lower mHHS and higher VAS compared with patients with continuous capsule (P < .05). Ninety-one percentage of patients with continuous capsule surpassed minimal clinically important difference (MCID) and 80.8% achieved PASS, but only 58.8% of patients with capsular defect surpassed MCID and 47.1% achieved patient acceptable symptom state (PASS). Conclusions Postoperative capsular thickness may not have influence on the clinical outcomes of hip arthroscopy for treatment of FAI. Some capsule of patients who underwent arthroscopic interportal capsulotomy and repair could not heal. Postoperative capsular continuity had a great impact on the clinical outcomes of hip arthroscopy for FAI. Patients with higher BMI may be more likely to have capsule failure to heal.

Matsuda DK. Editorial Commentary: Incremental Decompression of Cam Femoroacetabular Impingement Must Be Assessed in Real Time by Arthroscopic Dynamic Examination: Playbook for the Perfect Femoroplasty. Arthroscopy 2022; 38:1164-1165. [PMID: 35369919 DOI: 10.1016/j.arthro.2021.11.038] [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: 11/17/2021] [Accepted: 11/18/2021] [Indexed: 02/02/2023]
Abstract
The perfect femoroplasty varies with the individual patient's pathoanatomy and is a prime example of the art and science of surgery. Radiographs are two-dimensional representations of a three-dimensional reality and can miss detection of cam impingement. Cam impingement may occur without cam morphology as femoral retrotorsion and/or supraphysiological range of motion (e.g., dancers and martial artists) may cause cam impingement with normal α-angles and anterior offset. Acetabuloplasty or acetabular reorientation osteotomy may change the dynamic interaction between the proximal femur and acetabular rim and may alter the location and extent of cam decompression. Although much is discussed about the α-angle, restoration of anterior offset is also important. Incremental femoroplasty assessed in real time by arthroscopic dynamic examination is key, as the surgeon sculpts a nonimpinging proximal femur using a burr rather than a chisel in creating a customized surgical masterpiece.

Abstract
Background: Passive energy storage and return has long been recognized as one of the central mechanisms for minimizing the energy cost needed for terrestrial locomotion. Although the iliofemoral ligament (IFL) is the strongest ligament in the body, its potential role in energy-efficient walking remains unexplored. Purpose: To identify the contribution of the IFL to the amount of work performed by the hip muscles for normal, straight-level walking. Study Design: Controlled laboratory study. Methods: Straight-level walking of 50 healthy and injury-free adults was simulated using the AnyBody Modeling System. For each participant, the bone morphology and soft tissue properties were nonuniformly scaled. The superior and inferior parts of the IFL were represented by 2 springs each, and a linear force-strain relation was defined. A parameter study was conducted to account for the uncertainty surrounding the mechanical properties of the IFL. The work required from the gluteus, quadriceps, iliopsoas, and sartorius with and without inclusion of the IFL was calculated. Analysis of variance with subsequent post hoc paired t test was used to test the significance of IFL presence on the required mechanical work. Results: During walking, the strain in the IFL reached a median of 18.7% (95% CI, 8.0%-26.5%), with the largest values obtained at toe-off. With the IFL undamaged and fully operational, the effort required by the hip flexor muscles was reduced by a median of 54% (99% CI, 45%-62%) for the iliopsoas and by a median of 41% (99% CI, 27%-54%) for the sartorius muscles. The inclusion of the IFL did not significantly alter the work required by the gluteus and the quadriceps. Conclusion: The findings emphasized the key role the IFL plays in hip flexion by working synergistically with the hip musculature. Clinical Relevance: The importance of the contribution of the IFL to the hip flexors warrants careful handling and repair of these ligaments in cases of surgery and structural damage.

Changes in Hip Capsule Morphology after Arthroscopic Treatment for Femoroacetabular Impingement Syndrome with Periportal Capsulotomy are Correlated With Improvements in Patient-Reported Outcomes. Arthroscopy 2022; 38:394-403. [PMID: 34052373 PMCID: PMC8895710 DOI: 10.1016/j.arthro.2021.05.012] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 04/30/2021] [Accepted: 05/11/2021] [Indexed: 02/03/2023]
Abstract
PURPOSE To assess the correlation between changes in hip capsule morphology with improvements in patient-reported outcome (PRO) scores after arthroscopic surgery for femoroacetabular impingement syndrome (FAIS) using the periportal capsulotomy technique. METHODS Twenty-eight patients with cam morphology FAIS (without arthritis, dysplasia, or hypermobility) were prospectively enrolled before arthroscopic labral repair and femoroplasty through periportal capsulotomy (anterolateral/midanterior portals) without closure. Patients completed the Hip Disability and Osteoarthritis Outcomes Score (HOOS) and had nonarthrographic 3T magnetic resonance imaging (MRI) scans of the affected hip before and 1 year after surgery. Anterior capsule thickness, posterior capsule thickness, anterior-posterior capsule thickness ratio, and proximal-distal anterior capsule thickness ratio were measured on axial-oblique MRI sequences. Pearson correlation coefficients were calculated to determine the association between hip capsule morphology and PRO scores. RESULTS Postoperative imaging showed that for all 28 patients (12 female), labral repairs and capsulotomies had healed within 1 year of surgery. Analysis revealed postoperative decreases in anterior hip capsule thickness (1395.4 ± 508.4 mm3 vs 1758.4 ± 487.9 mm3; P = .003) and anterior-posterior capsule thickness ratio (0.92 ± 0.33 vs 1.12 ± 0.38; P = .02). Higher preoperative anterior-posterior capsule thickness ratio correlated with lower preoperative scores for HOOS pain (R = -0.43; P = .02), activities of daily living (ADL) (R = -0.43; P = .02), and sport (R = -0.38; P = .04). Greater decrease from preoperative to postoperative anterior-posterior capsule thickness ratio correlated with greater improvement for HOOS pain (R = -0.40; P = .04), ADL (R = -0.45; P = .02), and sport (R = -0.46; P = .02). CONCLUSIONS Periportal capsulotomy without closure demonstrates capsule healing by 1 year after arthroscopic FAIS treatment. Changes in hip capsule morphology including decreased anterior-posterior capsule thickness ratio after surgery may be correlated with improvements in patient pain, function, and ability to return to sports. LEVEL OF EVIDENCE Level II, prospective cohort study.

Abstract
PURPOSE OF REVIEW To characterize current concepts in capsular repair and hip instability, and examine findings from biomechanical and clinical studies on hip capsular management strategies as they pertain to hip stability, patient outcomes, and hip arthroscopy failure. Further, we discuss the clinical evaluation and treatment of capsular deficiency. RECENT FINDINGS There remains debate regarding the optimal capsular management strategies in hip arthroscopy, particularly concerning the necessity of routine capsular repair. A variety of capsulotomy techniques exist and may be used to access the hip joint. Additionally, a wide variety of techniques are employed to repair the hip capsule. Biomechanical evidence supports capsular closure restores hip joint stability to that of the intact, native state. Several clinical studies in both primary and revision hip arthroscopy settings have demonstrated improved pain and functional outcomes in patients who underwent capsular repair or capsular reconstruction. Studies have shown capsular repair may be especially important in patients with ligamentous laxity and hip dysplasia, and in competitive athletes. Post-surgical hip instability secondary to capsular insufficiency is increasingly recognized as a cause of hip arthroscopy failure. Capsular closure restores native biomechanical stability to the hip joint, and several clinical studies report improved pain and functional outcomes following capsular repair or capsular reconstruction in both the primary and revision hip arthroscopy settings. There remains much to learn regarding capsular hip instability as it relates to optimal capsular management surgical technique, intra-operative capsular management decision-making, clinical diagnosis, and related advanced imaging findings.

Pie-Crusting Capsulotomy Provides Similar Visualization With Increased Repair Stiffness Compared With a T-Capsulotomy: A Biomechanical Study. Arthroscopy 2021; 37:2832-2837. [PMID: 33812034 DOI: 10.1016/j.arthro.2021.03.044] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 03/21/2021] [Accepted: 03/21/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To compare the area of visualization, capsular stiffness, and strength between the pie-crusting capsulotomy technique and the T-capsulotomy technique following repair. METHODS Eight matched pairs of fresh-frozen cadaveric hips (n = 16) were divided to either T-capsulotomy or pie-crusting capsulotomy followed by subsequent repair. The area of visualization was measured for all capsulotomy states using a digitizing probe. Hips were then distracted along the iliofemoral ligament in the intact, extended capsulotomy, and repair states. Afterwards, specimens were externally rotated to failure. RESULTS An average force of 250.1 ± 16.1 N was required to distract intact hips to 6 mm. Both extended capsulotomy techniques reduced the force required to distract the hip 6 mm with no statistical difference between the two (T-capsulotomy [T-cap] = 114.3 ± 63.4 N vs pie-capsulotomy [Pie-cap] = 170.1 ± 38.8 N), P = .07. Subsequent repair of the extended capsulotomies demonstrated the pie-crust capsulotomy required significantly greater force to reach 6 mm of distraction than those with a repaired T-capsulotomy (T-cap = 165.04 ± 40.43N vs Pie-cap = 204.43 ± 10.13N), P = .03. There was no significant difference in ultimate torque to failure between the 2 techniques (T-cap = 22.0 ± 7.41 N·m vs Pie-cap = 27.01 ± 11.13 N·m), P = .28. Visualization significantly increased with each extended capsulotomy, with an average increase of 62% (P < .001) and 48% (P < .001) for the pie- and T-capsulotomies, respectively. CONCLUSIONS The pie-crusting technique maintained similar strength and increased stiffness to the T-capsulotomy following repair while using less suture. Both techniques provided similar visualization. Clinically, the pie-crusting technique provides an alternative to the T-capsulotomy with similar biomechanical and visual outcomes. CLINICAL RELEVANCE Visualization during hip arthroscopy can be difficult with large cam morphology. Techniques to improve visualization while restoring the native biomechanics of the hip as best as possible are important.

J Hip Preserv Surg 2021; 8:156-163. [PMID: 35145712 PMCID: PMC8826158 DOI: 10.1093/jhps/hnab059] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/09/2021] [Accepted: 07/19/2021] [Indexed: 11/30/2022] Open
Abstract
The aim of this study was to review and summarize the available biomechanical data on hip capsular reconstruction to guide clinical decision-making. A literature search was completed in December 2020 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify biomechanical cadaver studies on hip capsular reconstruction, hip capsulectomy or hip capsular defect. The investigated parameters included maximum distraction force, capsular state affecting range of motion (ROM), rotation and translation. Four studies met al. the inclusion–exclusion criteria. The median effective force for resisting maximum distraction for the reconstruction state, capsular defect state and the intact state was 171, 111 and 206 N, respectively. The defect capsule force was significantly lower (P = 0.00438) than the intact capsule force. The reconstruction state had a higher distraction force than that of the capsular defect, but due to heterogeneity, the overall effect size was not statistically significant. The capsular reconstruction state reduced excess motion and the degree of instability compared to the capsular defect state but restored the hip close to its native capsular state in the cadaveric model. When compared to capsulectomy/defect state, hip capsular reconstruction significantly improved the rotational stability and effective force at maximum distraction and minimized translation. However, no conclusions can be made regarding the most effective protocol due to the high heterogeneity between the four studies. Further biomechanical studies are needed to test various types of grafts under the same protocol.

Abstract
Objective To evaluate the midterm outcomes and the capsular healing in patients who had interportal capsulotomy versus periportal capsulotomy of hip arthroscopy. Methods Retrospectively reviewed 33 patients with labral tear received hip arthroscopy, with an average age of 41 (27‐67) years, including 13 cases of Cam deformity and three cases of Pincer deformity. All patients had positive sign of flexion adduction internal rotation or flexion abduction external rotation. With MRI and radiographic (CT, X plain) imageological examination. MRI showed that all patients had labral tear. Radiographic finding (CT, X plain) showed the pathological changes of acetabular and femoral neck osteophyte. One group with 23 patients were treated with periportal capsulotomy. Another group with 10 patients were treated with interportal capsulotomy. All patients did not close the capsule. Clinical outcomes were measured with the Hip Outcome Score Activities of Daily Living (HOS‐ADL) and the modified Harris Hip Score (mHHS), patient satisfaction measured with visual analogue scale (VAS). The healing of the capsule was evaluated by MRI. MRI showed continuous capsular indicated healing, discontinuous capsular indicated unhealing. Postoperatively 6 months, mHHS and HOS‐ADL were obtained. Randomized controlled trials were used in this study for analysis. Results All patients were followed up with average time of 9.3 months(3‐29 months). The postoperative symptoms were obviously relieved, the VAS decreased from (4.9 ± 0.6) to (1.2 ± 0.2) after 3 months postoperative. Follow up 6 months post‐operation, patients in the interportal group, the mHHS and HOS‐ADL scores improvement were respectively 69.4 ± 9.3 & 70 ± 8.8 pre‐operation, and 92.5 ± 5.0 & 86.6 ± 5.4 post‐operation (P < 0.05); Patients in the periportal group, the mHHS and HOS‐ADL scores improvement were respectively 69.9 ± 15.8, 68.1 ± 15.0 pre‐operation, and 90.1 ± 9.3 & 86.7 ± 7.9 post‐operation (P < 0.05).The differences were statistically significant. Six months after operation, MRI showed that 23 patients with periportal capsulotomy, the capsule have healed, without other complications. Three of the ten patients with interportal capsulotomy were healed and seven were not. Conclusion Interportal and periportal capsulotomy had good outcomes. The technique of periportal capsulotomy had little damage to the joint capsule. Although the capsule did not close, the capsule healed well in postoperative follow‐up. The nonunion rate of the joint capsule was high in the interportal capsulotomy without close the capsule.

Abstract
PURPOSE The aim of this systematic review was to evaluate the trends in the literature regarding surgical treatment for femoroacetabular impingement syndrome (FAIS) and to present which patient-reported outcome-measures (PROMs) and surgical approaches are included. METHODS This systematic review was conducted with the PRISMA guidelines. The literature search was performed on PubMed and Embase, covering studies from 1999 to 2020. Inclusion criteria were clinical studies with surgical treatment for FAIS, the use of PROMs as evaluation tool and studies in English. Exclusion criteria were studies with patients < 18 years, cohorts with < 8 patients, studies with primarily purpose to evaluate other diagnoses than FAIS and studies with radiographs as only outcomes without using PROMs. Data extracted were author, year, surgical intervention, type of study, level of evidence, demographics of included patients, and PROMs. RESULTS The initial search yielded 2,559 studies, of which 196 were included. There was an increase of 2,043% in the number of studies from the first to the last five years (2004-2008)-(2016-2020). There were 135 (69%) retrospective, 55 (28%) prospective and 6 (3%) Randomized Controlled Trials. Level of evidence ranged from I-IV where Level III was most common (44%). More than half of the studies (58%) originated from USA. Arthroscopic surgery was the most common surgical treatment (85%). Mean follow-up was 27.0 months (± 17 SD), (range 1.5-120 months). Between 1-10 PROMs were included, and the modified Harris Hip Score (mHHS) was most commonly used (61%). CONCLUSION There has been a continuous increase in the number of published studies regarding FAIS with the majority evaluating arthroscopic surgery. The mHHS remains being the most commonly used PROM.

Abstract
As hip arthroscopy has become increasingly used to treat femoroacetabular impingement, the importance of a complete femoroplasty to properly address cam impingement has been demonstrated. In doing so, different capsulotomy techniques have been described for gaining access to the hip joint as well as the peripheral compartment for cam resection. The periportal capsulotomy technique allows joint access while preserving the structural integrity of the iliofemoral ligament, obviating the need for capsular closure. We present a systematic approach and surgical technique for performing a complete arthroscopic femoroplasty while maintaining conservative hip capsule management through a periportal capsulotomy.

Abstract
The relationship between morphological characteristics of the hip capsule and patient symptoms in the setting of femoroacetabular impingement (FAI) is undefined. In this study, patients with symptomatic FAI prospectively underwent 3T magnetic resonance (MR) imaging of the affected hip and completed the hip disability and osteoarthritis outcome score (HOOS) to determine the correlation between hip capsule anatomy and patient symptoms. Anterior hip capsule volume, posterior capsule volume, anterior-posterior capsule volume ratio, and proximal-distal volume ratio in the anterior capsule were quantified and measured using axial-oblique intermediate-weighted 3D fast spin echo MR images. A total of 35 patients (35 hips) were included for analysis (mean age: 30.6 years; mean body mass index [BMI]: 24.9 kg/m2 ; 57% male). The mean alpha angle was 62.2° ± 4.7°, the mean anterior hip capsule volume was 1705.1 ± 450.3 mm3 , the mean posterior hip capsule volume was 1284.8 ± 268.5 mm3 , the mean anterior to posterior capsule volume ratio was 1.1 ± 0.39, and the mean proximal to distal volume ratio of the anterior capsule was 0.65 ± 0.28. There was no correlation between age, gender, or BMI, and any hip capsule characteristics. Worse scores on the HOOS pain scale were correlated with increased anterior to posterior volume ratio (r = -.38; 95% confidence interval: -0.06 to -0.63). In conclusion, hip capsule morphology correlates with patient symptoms in the setting of FAI as increased anterior capsular volume, relative to posterior capsular volume, is associated with greater patient pain.

Treatment of Labral Calcification in the Setting of Femoroacetabular Impingement Syndrome With Arthroscopic Calcification Excision, Labral Repair, and Osteoplasty Improves Outcomes. Arthroscopy 2021; 37:554-563. [PMID: 33122106 DOI: 10.1016/j.arthro.2020.10.033] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Revised: 10/10/2020] [Accepted: 10/16/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To describe the diagnosis and 2-year outcomes of arthroscopic treatment for labral calcification in the setting of femoroacetabular impingement syndrome (FAIS). METHODS A retrospective analysis was performed from a prospectively collected database of patients with FAIS undergoing hip arthroscopy. Patients with FAIS with labral calcification were differentiated radiographically from patients with other paralabral radiopaque densities such as os acetabuli, acetabular rim fractures, and labral ossification. Patients with FAIS with labral calcification were treated with arthroscopic calcification excision, labral repair, and osteoplasty and matched by age, sex, and body mass index with a cohort of patients with FAIS without labral calcifications who underwent labral repair and osteoplasty. Pre- and 2 years postoperatively, patients completed patient-reported outcome (PRO) scores including the modified Harris Hip Score, Hip disability and Osteoarthritis Outcome Score (HOOS), 12-item Short-Form survey, and visual analog scale. RESULTS In total, 40 hips (21 male, 19 female) with FAIS and labral calcification were included (age 36.8 ± 8.1, body mass index, 25.9 ± 4.5). Patients with FAIS with labral calcification demonstrated similar significant PRO score improvements compared with a matched cohort of patients with FAIS without labral calcification at 2 years after surgery (visual analog scale: (-)2.3 ± 0.4, (-)2.7 ± 0.5, modified Harris Hip Score: 16.1 ± 2.6, 17.1 ± 3.2; HOOS symptoms: 21.9 ± 3.7, 18.6 ± 3.6; HOOS pain: 22.1 ± 3.0, 25.0 ± 3.5; HOOS activities of daily living: 20.2 ± 2.8, 23.8 ± 3.3; HOOS sport: 35.6 ± 5.0, 35.6 ± 4.1; HOOS quality of life: 36.9 ± 4.5, 37.5 ± 4.4; 12-item Short-Form survey physical component summary: 15.5 ± 2.3, 20.1 ± 2.1, respectively). Both cohorts achieved minimal clinically important differences at equivalent rates (60%-82.5%) for all PRO scores. CONCLUSIONS Patients with labral calcification in the setting of FAIS can be effectively treated with arthroscopic calcification excision, labral repair, and osteoplasty. These patients demonstrate significant improvements in patient-reported outcomes and achievement of minimal clinically important differences at 2 years similar to patients undergoing arthroscopic treatment for FAIS without labral calcification. LEVEL OF EVIDENCE Level III, matched cohort study.

Arthroscopic Capsular Management of the Hip: A Comparison of Indications for and Clinical Outcomes of Periportal Versus Interportal Capsulotomy. Arthroscopy 2021; 37:86-94. [PMID: 32798668 DOI: 10.1016/j.arthro.2020.08.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 08/06/2020] [Accepted: 08/06/2020] [Indexed: 02/02/2023]
Abstract
PURPOSE To compare the clinical outcomes of periportal capsulotomy versus interportal capsulotomy with closure using a standard clinical algorithm at a minimum of 2 years after hip arthroscopy. METHODS A retrospective cohort study of patients treated from July 2015 to October 2017 was conducted to determine the effects of 2 capsular management approaches on clinical outcomes. When patient pathology limited adequate exposure via periportal capsulotomy, an interportal capsulotomy was performed. The capsular management approaches were correlated with the following patient-reported outcomes (PROs) at 2 years: Hip Outcome Score (HOS), 12-item International Hip Outcome Tool, visual analog scale for pain, and patient satisfaction. Preoperative comparisons between the 2 groups were analyzed using t tests or the Fisher exact test, depending on the category of data. Two-tailed independent t tests were performed to evaluate whether preoperative and follow-up outcome scores were significantly different between patients treated with a periportal capsulotomy and those treated with an interportal capsulotomy. RESULTS Overall, patients in both groups experienced significant improvements in all PROs on postoperative comparisons at 2-year follow-up (P < .001). The mean changes in the PROs were as follows: HOS-Activities of Daily Living, 24.7 in the periportal group and 23.5 in the interportal group (P = .484); HOS-Sport-Specific Subscale, 30.2 and 31.3, respectively (P = .895); 12-item International Hip Outcome Tool score, 41.9 and 40.2, respectively (P = .564); and visual analog scale pain score, -40.9 mm and -34.5 mm, respectively (P = .791). Additionally, no statistically significant difference in patient satisfaction at 2-year follow-up was found between patients who underwent interportal capsulotomy and those who underwent periportal capsulotomy (P = .604). CONCLUSIONS At 2-year follow-up, patients who underwent a periportal capsulotomy reported statistically and clinically significant improvements in PROs and satisfaction with the surgical intervention. This study confirms that the use of a simple clinical algorithm for selection of periportal capsulotomy or interportal capsulotomy with closure results in acceptable management decisions as defined by 2-year PROs. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Editorial Commentary: Evidence-Based Guidelines for Management of the Hip Capsule During Arthroscopy: Has It Become Personal? Arthroscopy 2021; 37:95-97.

Abstract
The management of the capsule during hip arthroscopy for femoroacetabular impingement syndrome has been in the spotlight during the last decade. Although there is robust biomechanical evidence that preserving the anatomic integrity of the iliofemoral ligament is important for the stability of the hip joint, the effect of capsular management on patient outcomes is often debated in clinical studies. Mid-term and long-term follow-up studies have shown that capsular closure is associated with decreased risk of hip arthroscopy failure, but no difference in patient outcomes based on capsular management has been found by some case series studies. What is driving the controversy in the literature? It seems to stem from the variation in surgical techniques used to perform hip capsulotomy or capsular repair, worldwide. Given that improvement in patient outcomes must be prioritized, it is time to use the existing knowledge appropriately to establish evidence-based guidelines for the management of hip capsule during hip arthroscopy.

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

Abstract
BACKGROUND Patients experience varying degrees of pain and symptoms during the early recovery period after hip arthroscopy for femoroacetabular impingement (FAI). Some "fast starters" report minimal discomfort and are eager to advance activities, while "slow starters" describe severe pain and limitations. The relationship between these early postoperative symptoms and 2-year outcomes after hip arthroscopy is unknown. PURPOSE To analyze the relationship between early postoperative pain and 2-year patient-reported outcomes (PROs) after hip arthroscopy for FAI. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Patients without arthritis or dysplasia who were undergoing primary hip arthroscopy for FAI were prospectively enrolled and completed validated PROs. Scores for visual analog scale (VAS) for pain were collected preoperatively and at 1 week, 6 weeks, and 2 years postoperatively. Scores for the modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score (HOOS), and 12-Item Short Form Health Survey (SF-12) were collected preoperatively and 2 years postoperatively. Paired t tests were used to evaluate PRO score changes, and correlation analyses were used to assess relationships between early postoperative pain and 2-year postoperative outcomes. RESULTS A total of 166 patients were included (55% female; mean ± SD age, 35.29 ± 9.6 years; mean body mass index, 25.07 ± 3.98 kg/m2). Patients demonstrated significant improvements in PRO scores (VAS, SF-12 Physical Component Score, mHHS, and all HOOS subscales) at 2 years after hip arthroscopy for FAI (P < .001). There was a significant correlation between lower 1-week VAS pain level (fast starters) and lower 2-year VAS pain level (R = 0.31; P < .001) as well as higher 2-year PRO scores (SF-12 Physical Component Score, mHHS, and all HOOS subscales: R = -0.21 to -0.3; P < .001). There was no correlation between 1-week VAS pain and 2-year SF-12 Mental Component Score (P = .17). Preoperative VAS pain levels showed positive correlations with 1-week postoperative pain scores (R = 0.39; P < .001) and negative correlations with 2-year patient outcomes (R = -0.15 to -0.33, P < .01). There was no correlation between 6-week postoperative pain scores and 2-year PRO scores. CONCLUSION Fast starters after hip arthroscopy for FAI experience sustained improvements in outcomes at 2 years after surgery. Patient pain levels before surgery may delineate potential fast starters and slow starters.

Abstract
Background Although patients have experienced significant improvements after hip arthroscopy for femoroacetabular impingement (FAI), prior studies suggest that women have worse outcomes than men. These previous studies lack comparisons of patient-reported outcome (PRO) scores based on gender with respect to clinical significance measurements, including the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS). Purpose To evaluate outcomes after hip arthroscopy for FAI based on patient gender by prospectively assessing changes in PRO scores, MCID, and PASS. Study Design Cohort study; Level of evidence, 2. Methods Women and men undergoing hip arthroscopy for FAI were prospectively enrolled, and preoperative radiographic and intraoperative findings were collected. Patients completed the following PRO surveys before surgery and 2 years postoperatively: modified Harris Hip Score (mHHS), Hip disability and Osteoarthritis Outcome Score (HOOS), and 12-Item Short Form Health Survey. Mean scores and percentage of patients reaching MCID and PASS were analyzed. Results A total of 131 hips were included (72 women, 59 men). Women had smaller preoperative alpha angles (59.1° vs 63.7°, respectively; P < .001) and lower acetabular cartilage injury grade (6.9% vs 22.0% with grade 4 injury, respectively; P = .013). Both women and men achieved equivalent significant improvements in PRO scores after surgery (scores increased 18.4 to 45.1 points for mHHS and HOOS). Women and men reached PASS for mHHS at similar rates (76.4% and 77.2%, respectively; P = .915). MCID was also achieved at similar rates between women and men for all scores (range, 61.4%-88.9%) except the activities of daily living subscale of the HOOS, in which a greater percentage of women reached MCID compared with men (79.2% vs 62.7%, respectively; P = .037). Additional stratification by age group using the median cohort age of 34 years showed no significant differences in PRO improvement based on age group for each gender. Conclusion Women can achieve clinically meaningful improvements in PRO scores after hip arthroscopy for FAI. Compared with men, women demonstrated equivalent high rates of achieving MCID and PASS at 2 years after surgery.

Abstract
PURPOSE To identify potential differences in interportal capsulotomy size and cross-sectional area (CSA) using the anterolateral portal (ALP) and either the: (i) standard anterior portal (SAP) or (ii) modified anterior portal (MAP). MATERIALS AND METHODS Ten cadaveric hemi pelvis specimens were included. A standard arthroscopic ALP was created. Hips were randomized to SAP (n=5) or MAP (n=5) groups. The spinal needle was placed at the center of the anterior triangle or directly adjacent to the ALP in the SAP and MAP groups, respectively. A capsulotomy was created by inserting the knife through the SAP or MAP. The length and width of each capsulotomy was measured using digital calipers under direct visualization. The CSA and length of the capsulotomy as a percentage of total iliofemoral ligament (IFL) side-to-side width were calculated. RESULTS There were no differences in mean cadaveric age, weight or IFL dimensions between the groups. Capsulotomy CSA was significantly larger in the SAP group compared with the MAP group (SAP 2.16±0.64 cm2 vs. MAP 0.65±0.17 cm2, P=0.008). Capsulotomy length as a percentage of total IFL width was significantly longer in the SAP group compared with the MAP group (SAP 74.2±14.1% vs. MAP 32.4±3.7%, P=0.008). CONCLUSION The CSA of the capsulotomy and the percentage of the total IFL width disrupted are significantly smaller when the interportal capsulotomy is performed between the ALP and MAP portals, compared to the one created between the ALP and SAP. Surgeons should be aware of this fact when performing hip arthroscopy.

Abstract
Background Hip arthroscopy is a common surgical intervention for young and middle-aged adults with hip-related pain and dysfunction, who have high expectations for returning to physical activity following surgery. The purpose of this review was to evaluate the impact of hip arthroscopy on physical activity post-arthroscopy. Methods A systematic search of electronic databases was undertaken in identifying studies from January 1st 1990 to December 5th 2019. The search included English language articles reporting physical activity as an outcome following hip arthroscopy in adults aged 18-50 years. Quality assessment, data extraction and synthesis of included studies were undertaken. Results Full text articles (n = 234) were assessed for eligibility following screening of titles and abstracts (n = 2086), yielding 120 studies for inclusion. The majority (86%) of the studies were level 4 evidence. One study reported objective activity data. The most frequently occurring patient-reported outcome measure was the Hip Outcome Score-sport-specific subscale (HOS-SS, 84% of studies). Post--arthroscopy improvement was indicated by large effect sizes for patient-reported outcome measures (standard paired difference [95% confidence interval] −1.35[−1.61 to −1.09] at more than 2 years post-arthroscopy); however, the majority of outcome scores for the HOS-SS did not meet the defined level for a patient-acceptable symptom state. Conclusion The current level of available information regarding physical activity for post arthroscopy patients is limited in scope. Outcomes have focused on patients’ perceived difficulties with sport-related activities with a paucity of information on the type, quality and quantity of activity undertaken. Level of Evidence Level IV, systematic review of Level 2 through to Level 4 studies

Abstract
➤Hip joint capsular ligaments (iliofemoral, ischiofemoral, and pubofemoral) play a predominant role in functional mobility and joint stability. ➤The zona orbicularis resists joint distraction (during neutral positions), and its aperture mechanism stabilizes the hip from adverse edge-loading (during extreme hip flexion-extension). ➤To preserve joint function and stability, it is important to minimize capsulotomy size and avoid disrupting the zona orbicularis, preserve the femoral head size and neck length, and only repair when or as necessary without altering capsular tensions. ➤It is not fully understood what the role of capsular tightness is in patients who have cam femoroacetabular impingement and if partial capsular release could be beneficial and/or therapeutic. ➤During arthroplasty surgery, a femoral head implant that is nearly equivalent to the native head size with an optimal neck-length offset can optimize capsular tension and decrease dislocation risk where an intact posterior hip capsule plays a critical role in maintaining hip stability.

Abstract
PURPOSE OF REVIEW To assess the outcomes of modern techniques for arthroscopic surgery in the treatment of femoroacetabular impingement. RECENT FINDINGS While initially approached by means of open surgical hip dislocation, recent literature has shown generally good outcomes of arthroscopic treatment for femoroacetabular impingement. Modern advances in hip arthroscopy technique and implants now allow for labral repair or reconstruction when indicated. Arthroscopic treatment of femoroacetabular impingement results in significant improvements in patient pain and function, with low complication rates and high patient satisfaction. A majority of improvements in these patients occur within 1 to 2 years post-operatively. Hip arthroscopy for femoroacetabular impingement yields the best results in patients without significant arthritis or hip dysplasia.

Abstract
PURPOSE OF REVIEW To review the relevant literature and techniques regarding arthroscopic and open treatment of femoroacetabular impingement (FAI). To discuss both the senior authors' preferred method of arthroscopic and open treatment of FAI. RECENT FINDINGS Routine treatment of FAI has moved away from open techniques and is more focused arthroscopic methods. Arthroscopic treatment of FAI has more recently focused on differing techniques of hip access and capsular management. Open techniques still have a role in FAI, but indications for open management are focused on cases with more severe pathology. While arthroscopic techniques have shown better outcomes in the short term and higher return to play, it is not without risk and is a procedure with a steep learning curve. In cases of complex joint pathology, such as FAI coupled with dysplasia or Legg-Calve-Perthes, arthroscopy may be not indicated and an open approach preferred. We outline various techniques for both arthroscopic and open treatment of FAI and their outcomes when possible.

Abstract
When treating femoroacetabular impingement, appropriate visualization is needed to technically perform a complete osteoplasty. Adequate visualization typically requires some level of disruption of the hip capsule during the surgical approach. As a result, complications including microinstability or frank dislocation may result from any violation of the hip capsule. There is a trade-off involved in the various capsular approaches: the balance between appropriate visualization in order to adequately perform a complete femoral osteoplasty versus disruption of the capsule, potentially causing iatrogenic hip instability. If visualization is compromised, it is better to extend a capsulotomy than to have a burr, shaver, or electrocautery remove part of the capsular envelope. In the end, the solution is to use an approach that allows you to visualize and treat the femoroacetabular impingement pathology, yet maintain the integrity of the capsular envelope.
