Regarding “Midterm Outcomes Following Repair of Capsulotomy Versus Nonrepair in Patients Undergoing Hip Arthroscopy for Femoroacetabular Impingement With Labral Repair”

Abstract Multiple self-reported allergies have been reported as a prognostic factor for outcome the following orthopedic procedures. This relationship has not yet been evaluated in a hip arthroscopy population. The purpose of this study is to identify associations between allergies and post-operative outcome scores in patients undergoing hip arthroscopy for femoroacetabular impingement (FAI). A retrospective review of surgically treated FAI patients at our institution was performed. Patient-reported allergies and 6-month and 1-year modified Harris Hip Scores (mHHS) were recorded. Bivariate analysis was performed evaluating association between allergies and post-operative mHHS. Multivariate regression was used to identify independent factors associated with post-operative mHHS while controlling for age, sex, BMI, psychiatric comorbidity, symptom duration, labral repair versus debridement, capsular management, chondral lesions and use of adjunct platelet rich plasma (PRP). Seventy patients were analysed. Average age was 30.7 years old (SD 8.96). A 52.9% were females. Twenty-six patients (37.1%) had reported allergies. At 6 months, bivariate analysis demonstrated no significant association between allergies and postop mHHS. This was true comparing patients with 0 versus 1 versus 2 versus 3 versus 5 allergies as separate groups (medians from 83.1 to 91.0, P = 0.60) as well as when combining patients with >2 allergies into one group (0 versus 1 versus 2–5 allergies) (medians 84.7, 83.1, 86.0, respectively, P = 0.328). At 1 year, this lack of association was more pronounced (0 versus 1 versus 2 versus 3 versus 5: medians from 87.0 to 93.5, P = 0.9265 and 0 versus 1 versus 2–5: medians 93.5, 91.7, 89.0, respectively, P = 0.6450). Linear regression demonstrated preop mHHS and age were significantly associated with 1-year mHHS (logit mHHS rate = 0.026 ± 0.008 per unit, P = 0.0014 for preop mHHS and logit mHHS rate=−0.061 ± 0.018 per year, P = 0.0010 for age). After controlling for age and preop mHHS, allergies were not associated with postop mHHS. Allergies demonstrated no association with post-operative outcome following surgical treatment of FAI.

Background: Previous studies have demonstrated hip arthroscopy to be an effective treatment for femoroacetabular impingement (FAI) in individuals 18 years of age and older. Long-term outcome data in the adolescent population, however, are limited. Purpose: To report 10-year outcomes after hip arthroscopy in adolescents with symptomatic FAI. Study Design: Case series; Level of evidence, 4. Methods: Prospectively collected data were analyzed on adolescent patients younger than 18 years of age who had hip arthroscopy between March 2005 and 2009 with a minimum 10-year follow-up. Patients were included if they were diagnosed with symptomatic FAI and an associated labral tear that was treated with repair. Patients were excluded if they had previous hip procedures, acetabular dysplasia (lateral center-edge angle, <20°), avascular necrosis, previous hip fracture or dislocation, or Legg-Calve-Perthes disease, or refused to participate. The primary patient-reported outcome measure was the Hip Outcome Score (HOS) Activities of Daily Living (ADL) subscale. In addition, the HOS—Sport, modified Harris Hip Score (mHHS), 12-Item Short Form Health Survey (SF-12), and patient satisfaction were collected. Failure was defined as patients having to undergo revision arthroscopy. Results: There were 60 patients (70 hips) who met inclusion criteria and had a 10-year follow-up. The mean age of the cohort was 16 ± 1.2 years, with 21 male and 49 female hips. Seven hips (10%) required revision hip arthroscopy. All revisions occurred in female patients and were associated with global laxity as well as longer duration of symptoms before time of surgery. At a mean follow-up of 12 years (range, 10-14 years), patients who did not undergo revision surgery had significant improvements from preoperatively to postoperatively in HOS-ADL (from 64 to 92; P < .01), HOS–Sport (from 40 to 86; P < .01), mHHS (from 56 to 88; P < .01), and SF-12 Physical Component Summary (from 41 to 54; P < .01). The median patient satisfaction was 10 out of 10 (very satisfied). Conclusion: Hip arthroscopy for FAI with labral repair resulted in excellent patient-reported outcomes and satisfaction at a minimum of 10 years of follow-up. There was a 10% rate of revision surgery, which was associated with global laxity and longer duration of symptoms before surgery, which should be considered in patient selection.

Abstract In an attempt to bridge the osteoarthritis (OA) gap, this study compared biological reconstruction with traditional microfracture (MF) techniques in patients with femoroacetabular impingement and focal cartilage defects. Cohorts of two groups were investigated; age, gender and Tonnis grade matched comparison for outcomes between MF and newer biological reconstruction techniques hip arthroscopy surgery using autologous matrix-induced chondrogenesis and bone marrow aspirate combination. Outcomes investigated were pre-op and post-op mean iHOT-12 scores up to 18 months after surgery with a Kaplan–Meier survivorship analysis. Of 111 patients, 46 patients underwent MF and 65 biological reconstruction hip arthroscopy including cam/pincer osteoplasty and labral repair surgery. Age range was 20–69, mean age 45 years for both groups, Tonnis grading was as follows: Grade 0: 26% versus 30%, Grade 1: 52% versus 47% and Grade 2: 22% versus 23% in MF and biological reconstruction groups, respectively. The mean post-operative iHOT-12 score differences between MF and biological reconstruction were significant at 1-year minimum follow-up (P = 0.01, SD 2.8). Biological reconstruction allowed for an enhanced recovery protocol. The MF group had a 67.4% survivorship for conversion to hip replacement at 18 months (32.6% failure rate for any reason) and biological reconstruction had 100% survivorship at 18 months post-operatively with no failures for any reason. This study provides further support to the evidence base for biological reconstructive techniques as superior to MF in combination with joint preservation arthroscopic surgery, even in the face of focal cartilage defects and offers both surgeons and patients a potential bridging of the OA gap.

Femoroacetabular Impingement Syndrome

ABSTRACT To report the minimum 5-year outcome after hip arthroscopy with labral repair in adolescents. From 2011 to 2014, 29 consecutive patients with a mean age 16.3 years (range 12.7–19.8 years) underwent hip arthroscopy treatment for femoroacetabular impingement syndrome. Patient-related outcome measures (PROMs) including modified Harris Hip Score (mHHS), Visual Analog Scale (VAS) for pain and Copenhagen Hip and Groin Outcome Score (HAGOS) were used preoperatively and at follow-up (FU). Percentage of patients achieving minimum clinically important difference (MCID) and substantial clinical benefit (SCB) for mHHS and HAGOS were determined. Mean FU was 6.7 years (range 5–9.6 years), and a 100% FU was accomplished. Significant improvements were seen for all PROMs at FU in patients not having a periacetabular osteotomy (PAO) with VAS pain score improving from mean 62 to 9, mHHS from 58 to 94 and HAGOS improved in all subgroups. For mHHS, SCB changes were achieved by 76% and MCID by 76% of the patients. Percentage of patients achieving MCID for HAGOS subgroups were 81% for pain, 67% for symptoms, 76% for physical function in daily living, 76% for physical function in sport and recreation, 81% for participation in physical activities and 81% for hip-related quality of life. Two patients had revision hip arthroscopy. PAO was later performed in three patients. The risk of further surgery with center edge (CE) bony edge (CEB) <30° was 42% and 0% with CEB ≥30°. Adolescents having hip arthroscopy with labral repair and resection of cam and pincer morphology achieve significant improvements at mean 6.7 years of FU. CEB < 30° increases the risk of further surgery.

Fai Syndrome

Background: Femoroacetabular impingement (FAI) syndrome is a common source of hip pain associated with chondrolabral injury. There is a subset of patients with FAI syndrome who present with radiopaque densities (RODs) adjacent to the acetabular rim. Purpose: To evaluate the prevalence, characteristics, and patient-specific factors associated with RODs adjacent to the acetabulum in patients treated with hip arthroscopy for symptomatic FAI. Study Design: Case series; Level of evidence, 4. Methods: Between November 2014 and March 2018, a total of 296 patients who underwent hip arthroscopy for FAI with a labral tear were reviewed retrospectively. Patient-specific variables were collected, including age, sex, lateral center-edge angle (LCEA), and alpha angle. Imaging (computed tomography) and surgical reports were reviewed for the location and characteristics of RODs, as well as subsequent labral treatment technique. Patients were excluded if they were treated for extra-articular hip pathology, had a revision procedure, or had a diagnosis other than FAI with a labral tear. No patient was excluded for any history of systemic inflammatory disease. Binary logistic regression was used to compare age, LCEA, and alpha angle for patients with or without radiopaque fragments. An alpha level of 0.05 was used to indicate statistical significance. Results: A total of 204 patients met inclusion criteria; 33 patients (16.2%; 16 males, 17 females) had para-acetabular RODs. There were no statistically significant differences in age ( P = .82), sex ( P = .92), LCEA ( P = .24), or alpha angle ( P = .10) among patients with or without an ROD. Of the 33 patients, 29 (87.9%) had fragments in the anterosuperior quadrant. Overall, 31 patients (93.9%) were treated with labral repair in addition to correction of the underlying bony impingement, while 2 patients (6.1%) underwent focal labral debridement owing to poor labral tissue quality around the RODs. Twenty-five patients (76%) had identifiable RODs, which were excised at the time of surgery. The mean (± SD) ROD size measured on axial and coronal computed tomography imaging was 6.3 ± 5.5 mm and 4 ± 4.5 mm, respectively. Conclusion: Age, sex, LCEA, and alpha angle were not predictive of the presence of para-acetabular RODs. Approximately one-sixth of all patients with FAI had RODs identified on computed tomography, which were typically located at the anterosuperior acetabulum. The majority of hips with para-acetabular RODs were amenable to labral repair. The relative prevalence and lack of predictive patient-specific indicators for these fragments suggest that a high degree of suspicion is necessary when evaluating patients with FAI.
