Patients Obtain Meaningful Clinical Benefit After Hip Arthroscopy Despite Preoperative Psychological Distress: A Propensity-Matched Analysis of Mid-Term Outcomes. Arthroscopy 2022; 38:773-782. [PMID: 34019982 DOI: 10.1016/j.arthro.2021.05.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 04/20/2021] [Accepted: 05/05/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the influence of baseline psychological distress on patient-reported outcomes (PROs) after arthroscopic hip surgery for femoroacetabular impingement at a minimum of 5 years. METHODS Demographic and intraoperative data were prospectively collected from patients who underwent primary arthroscopic hip surgery for femoroacetabular impingement and labral tears after failure of conservative management between June 2012 and December 2014. Included patients had preoperative and minimum 5-year postoperative PROs and visual analog scale scores for pain and satisfaction. The 12-item Short Form Health Survey (SF-12) Mental Component Summary (MCS) score was used to stratify patients into 2 cohorts: Patients with an average or above-average score (SF-12 MCS score ≥ 50) were considered psychologically non-distressed, whereas those who scored below average (SF-12 MCS score < 50) were considered to have psychological distress. Distressed patients were propensity matched by age, sex, and body mass index to an equal number of non-distressed patients. RESULTS Of the 153 hips that met the inclusion criteria, 117 (76.5%) had minimum 5-year follow-up. Eighty-two hips were included in the final analysis after propensity matching, with 41 in both the distressed and non-distressed cohorts. Preoperatively, patients in the distressed cohort reported inferior scores for all PROs. There was a significant difference in the SF-12 MCS score between groups at 2 years, but similar scores were observed for all other PROs. At minimum 5-year follow-up, there were no differences between groups for any PRO. There were no differences in the rates of achieving the minimal clinically important difference for all PROs or in achieving the patient acceptable symptomatic state for the modified Harris Hip Score. CONCLUSIONS Patients with baseline psychological distress may have a lower functional status at the time of presentation but still gain meaningful clinical benefit and pain improvement from arthroscopic hip surgery, with mid-term outcomes comparable to those obtained by patients without preoperative psychological distress. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
BACKGROUND Athletes who compete in flexibility sports (FS) place unique demands on their hip joints because of the supraphysiologic range of motion required. PURPOSE To compare the pathologic features, outcomes, and return-to-sports (RTS) rates of high-level athletes participating in FS who underwent hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear against a propensity score-matched cohort of high-level athletes participating in non-flexibility sports (NFS). STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for high-level athletes who underwent primary hip arthroscopy for FAIS from April 2008 to December 2018. Patients who participated in FS such as dancing, gymnastics, martial arts, figure skating, and cheerleading were propensity score matched by body mass index, age at time of surgery, sex, sports competition level, and labral treatment to a cohort of high-level athletes participating in all other sports, such as distance running, soccer, volleyball, and softball. Baseline patient characteristics, intraoperative findings, and surgical procedures were compared. Minimum 2-year patient-reported outcome measures were compared for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale for pain and satisfaction. Rates of secondary surgery and RTS were compared. RESULTS A total of 47 patients (50 hips) who participated in FS were included and propensity score matched to 130 patients (150 hips) who participated in NFS. Follow-up time was 37.5 ± 10.4 months (mean ± SD). Most patients (96.0%) were female with a mean age of 19.5 ± 7.3 years. FS athletes had significantly higher rates of femoral head cartilage lesions (Outerbridge ≥2; 12.0% vs 2.0%; P = .008) and ligamentum teres tears (48% vs 26%; P = .003). FS and NFS athletes demonstrated significant clinical improvements after surgery for all patient-reported outcome measures. Of the patients who attempted, 34 (75.6%) participating in FS were able to RTS while 11 (24.4%) were not because of ongoing hip issues. This was not significantly different than the NFS group (P = .073). CONCLUSION High-level athletes who participated in FS and were treated for FAIS with hip arthroscopy exhibited higher rates of femoral head cartilage lesions and ligamentum teres tears requiring debridement when compared with a benchmark group of athletes who participated in other sports. Despite this, both groups demonstrated similar improvements in outcome scores and comparable rates of RTS at minimum 2-year follow-up.

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. Orthop J Sports Med 2022; 10:23259671221075642. [PMID: 35237697 PMCID: PMC8882953 DOI: 10.1177/23259671221075642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Accepted: 11/12/2021] [Indexed: 11/16/2022] Open
Abstract
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

Abstract
BACKGROUND The effect of high body mass index (BMI) on outcomes in athletes has not been established. PURPOSE (1) To report minimum 2-year patient-reported outcome (PRO) scores and return to sports (RTS) for high-level athletes with high BMI undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and (2) to compare results with a propensity-matched control group of high-level athletes with a normal BMI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were collected on all professional, collegiate, and high school athletes who had a high BMI (>30) and who had undergone primary hip arthroscopy for FAIS between January 2010 and December 2018. RTS status and minimum 2-year PROs were collected for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. The percentage of patients achieving the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) were also recorded. These patients were propensity matched in a 1:3 ratio to high-level athletes with a normal BMI for comparison. RESULTS A total of 30 high-level athletes with a high BMI were included with a mean follow-up of 49.4 ± 29.5 months. They demonstrated significant improvement from preoperatively to latest follow-up for mHHS, NAHS, HOS-SSS, and VAS (P < .001). When outcomes were compared with a propensity-matched control group of 90 athletes with a normal BMI, athletes with a high BMI had worse acetabular cartilage injury and were more likely to undergo acetabular microfracture (P < .001). Athletes with a high BMI demonstrated lower postoperative scores for NAHS when compared with athletes with a normal BMI (88.06 ± 9.37 [range, 60-100] and 90.25 ± 10.79 [range, 48.75-100], respectively; P = .049). Athletes with a high BMI also demonstrated worse postoperative scores for HOS-SSS when compared with athletes with a normal BMI (77.22 ± 18.31 [range, 22.22-100] and 82.38 ± 22.79 [range, 2.78-100], respectively; P = .038). Rates of achieving MCID for the high-BMI and normal-BMI groups were comparable in mHHS (90.0% and 77.8%, respectively; P = .185) and HOS-SSS (90.0% and 82.2%, respectively; P = .397). PASS rates were also comparable between the high- and normal-BMI groups for mHHS (90.0% and 87.8%, respectively; P > .999) and HOS-SSS (70.0% and 71.1%, respectively; P = .908). Athletes with a high BMI also returned to sports at a lower rate compared with athletes with a normal BMI, but this did not reach statistical significance (P = .479). CONCLUSION Athletes with a high BMI undergoing primary hip arthroscopy for FAIS demonstrated significant improvement in PROs and favorable rates achieving clinically meaningful improvement. When compared with a control group of high-level athletes with a normal BMI, they exhibited similar rates of achieving psychometric thresholds and RTS rates. At short-term follow-up, high BMI did not adversely affect outcomes of high-level athletes undergoing primary hip arthroscopy.

Abstract
BACKGROUND There is a paucity of literature evaluating the effect of low body mass index (BMI) in female patients undergoing primary hip arthroscopy. PURPOSE (1) To report minimum 2-year patient-reported outcome scores for female patients with low BMI who underwent primary hip arthroscopy for femoroacetabular impingement syndrome and (2) to compare these results with a propensity-matched control group of female patients with normal BMI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were collected on all female patients who had low BMI (<18.5) and underwent primary hip arthroscopy between April 2008 and January 2019. Patients were excluded if they had a previous hip arthroscopy; had workers' compensation; were unwilling to participate in the study; or had Tönnis osteoarthritis grade >1, acetabular dysplasia, or a previous hip condition. Minimum 2-year patient-reported outcomes were collected for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score, Hip Outcome Score-Sport Specific Subscale (HOS-SSS), visual analog scale for pain, and satisfaction. The percentage of patients achieving the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and maximum outcome improvement satisfaction threshold (MOIST) was also recorded. These patients were propensity matched in a 1:2 ratio to female patients with normal BMI for comparison. RESULTS A total of 43 patients (49 hips) were included with a mean ± SD follow-up of 26.9 ± 8.3 months, age of 24.1 ± 12.6 years, and BMI of 17.7 ± 0.67. These patients demonstrated significant improvement from presurgery to minimum 2-year follow-up for the mHHS, Non-Arthritic Hip Score, HOS-SSS, and visual analog scale (P < .05). When outcomes were compared with 93 control patients (97 hips), female patients with low BMI demonstrated lower rates of achieving the PASS for the mHHS (61.2% vs 77.3%; P = .041) and HOS-SSS (39.5% vs 57.1%; P = .031). Rates of achieving the MCID and MOIST were similar between the groups (P > .05). Female patients with low BMI also had higher rates of revision when compared with the control group, but this did not reach statistical significance (14.2% vs 7.2%; P = .171). CONCLUSION Female patients with low BMI undergoing primary hip arthroscopy for femoroacetabular impingement syndrome demonstrated significant improvement in patient-reported outcomes at minimum 2-year follow-up. When compared with a propensity-matched control group with normal BMI, these patients demonstrated lower rates of achieving the PASS for the mHHS and HOS-SSS. Low BMI in females undergoing primary hip arthroscopy for FAIS may adversely affect outcomes at short-term follow-up.

BACKGROUND The effect of low body mass index (BMI) on outcomes in female athletes is unknown. PURPOSE (1) To report minimum 2-year patient-reported outcomes and return to sports for high-level female athletes with low BMI undergoing hip arthroscopy for femoroacetabular impingement syndrome and (2) to compare results with those of a propensity-matched control group of high-level female athletes with a normal BMI. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were collected on all professional, collegiate, and high school female athletes who had a low BMI and underwent primary hip arthroscopy between September 2009 and March 2017 at our institute. Return-to-sports status and minimum 2-year patient-reported outcomes were collected for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and visual analog scale (VAS) for pain. The percentage of patients achieving the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and maximum outcome improvement satisfaction threshold (MOIST) was also recorded. These patients were propensity matched to high-level female athletes with a normal BMI for comparison. RESULTS A total of 21 high-level female athletes (25 hips) with a mean ± SD follow-up of 58.9 ± 31.5 months were included. They demonstrated significant improvement from preoperatively to latest follow-up for the mHHS, Nonarthritic Hip Score, Hip Outcome Score-Sport Specific Subscale, and VAS (P < .001). When outcomes were compared with those of the control group, female athletes with low BMI demonstrated lower rates of achieving the MCID for the mHHS (54.5% vs 77.4%; P = .041), PASS for the International Hip Outcome Tool-12 (45.5% vs 72.6%; P = .022), and MOIST for the VAS (31.8% vs 56.5%; P = .047). There were no other significant differences in the rate of achieving the MCID, PASS, or MOIST between the groups (P > .05). Female athletes with low BMI also had higher rates of revision when compared with the control group (27.2% vs 10.6%; P = .049), but there were comparable return-to-sports rates (75.0% vs 74.5%; P > .05). CONCLUSION High-level female athletes with low BMI undergoing primary hip arthroscopy for femoroacetabular impingement syndrome demonstrated significant improvement in patient-reported outcomes and acceptable rates of return to play. When compared with a control group with normal BMI, they exhibited higher rates of revision and lower rates of achieving the MCID for the mHHS, PASS for the International Hip Outcome Tool-12, and MOIST for the VAS.

Abstract
BACKGROUND Patient-reported outcomes (PROs) and return to sports (RTS) after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) have not been established in elite athletes with coexisting low back pain (LBP). PURPOSE (1) To report minimum 2-year PROs and RTS rates after primary hip arthroscopy for FAIS in elite athletes with coexisting LBP and (2) to compare clinical results with a propensity-matched control group of elite athletes without back pain. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were reviewed for elite athletes (college and professional) who underwent hip arthroscopy for FAIS and had coexisting LBP between October 2009 and October 2018. Inclusion criteria were preoperative and minimum 2-year follow-up for the modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia (lateral center-edge angle <18°), and previous ipsilateral hip or spine surgery or conditions. Rates of achieving the minimal clinically importance difference (MCID), patient acceptable symptomatic state (PASS), and maximum outcome improvement satisfaction threshold were recorded in addition to RTS. For the subanalysis, the elite athlete study group was propensity matched to an elite athlete control group without back pain. RESULTS A total of 48 elite athletes with LBP who underwent primary hip arthroscopy met inclusion criteria, and follow-up was available for 42 (87.5%) at 53.2 ± 31.6 months (mean ± SD). Elite athletes with coexisting LBP demonstrated significant improvements in all recorded PROs and achieved the MCID and PASS for the HOS-SSS at rates of 82.5% and 67.5%, respectively. They also returned to sports at a high rate (75.8%), and 79% of them did not report LBP postoperatively. PROs, rates of achieving the MCID and PASS for the HOS-SSS, and RTS rates were similar between the study group and propensity-matched control group. CONCLUSION Elite athletes with coexisting LBP who undergo primary hip arthroscopy for FAIS may expect favorable PROs, rates of achieving the MCID and PASS for the HOS-SSS, and RTS rates at minimum 2-year follow-up. These results were comparable to those of a propensity-matched control group of elite athletes without back pain. In athletes with hip-spine syndrome, successful treatment of their hip pathology may help resolve their back pain.

Abstract
BACKGROUND Sex-based differences have been largely uncharacterized for patients with borderline hip dysplasia (BHD) undergoing hip arthroscopy. PURPOSE To evaluate for sex-based differences in clinical and pathologic characteristics as well as surgical outcomes in patients with BHD undergoing hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Between January 2011 and December 2018, data were prospectively collected on all patients with BHD undergoing primary hip arthroscopy. Patients were included if they had preoperative and minimum 2-year postoperative scores for the modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), and visual analog scale for pain. Patients with previous ipsilateral hip conditions or surgery, Tönnis grade >1, lateral center-edge angle <18° or >25°, or workers' compensation status were excluded. Patients were then divided by sex and propensity score matched in a 1:1 ratio for body mass index, age, and Tönnis grade. The rates of patients who achieved the minimal clinically important difference were recorded for the mHHS and NAHS. The rates of achieving the patient acceptable symptomatic state for the mHHS were calculated. RESULTS A total of 344 hips met the inclusion criteria, and 317 hips (92%) had adequate follow-up. Propensity score matching created cohorts of 109 male and 109 female patients. Male patients had significantly higher preoperative average alpha angles (69.79° vs 58.17°, P < .001), more often requiring a femoroplasty (97.2% vs 83.5%, P < .001), and had higher rates of complex labral tearing (50.5% vs 33.0%, P < .001). Male patients also had higher rates of grade 3 and 4 acetabular labral articular disruption (62.4% vs 19.3%, P < .001) and higher rates of grade 3 and 4 acetabular cartilage injury (59.6% vs 20.2%, P < .001) requiring a microfracture more frequently (32.1% vs 7.3%, P < .001). Female patients more typically had painful internal snapping requiring iliopsoas fractional lengthening (60.6% vs 32.1%, P < .001). Female patients also underwent capsular plication more regularly to address hip instability (79.8% vs 45.9%, P < .001). Male and female patients showed significant improvements in all outcome scores after surgery (P < .001). Female patients achieved the minimal clinically important difference for the NAHS at higher rates (85.3% vs 71.6%, P = .020). CONCLUSION Female and male patients with BHD who underwent hip arthroscopy achieved favorable outcomes but had notably dissimilar pathology. Hence, although they share similar acetabular bony morphology, male and female patients with BHD may represent 2 very different pathologic entities.

Trochlear Dysplasia as Shown by Increased Sulcus Angle Is Associated With Osteochondral Damage in Patients With Patellar Instability. Arthroscopy 2021; 37:3469-3476. [PMID: 33964393 DOI: 10.1016/j.arthro.2021.04.054] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Revised: 04/14/2021] [Accepted: 04/23/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The primary study objective was to describe the incidence of osteochondral damage (OD) in our cohort of patients with patellar instability (PI). The secondary objective was to assess for associations between patient demographic characteristics, duration of PI, and quantitative radiographic measurements of anatomic risk factors for PI and OD in this cohort. METHODS A retrospective chart review identified patients treated for PI at a tertiary referral center between 2013 and 2018. Patients were evaluated for osteochondral injury with either magnetic resonance imaging if treated nonoperatively or operative reports if treated surgically. The Caton-Deschamps ratio, proximal tibial tubercle-to-trochlear groove (pTT-TG) distance, distal tibial tubercle-to-trochlear groove (dTT-TG) distance, lateral trochlear inclination (LTI) angle, lateral patellar inclination (LPI) angle, and sulcus angle were calculated from magnetic resonance imaging scans. Trochlear dysplasia is an important risk factor for PI that can be reliability quantified by the pTT-TG distance, dTT-TG distance, LTI angle, sulcus angle, and LPI angle. Demographic data including age at first instability event, sex, body mass index, symptom duration, and number of dislocations were documented. RESULTS A total of 125 knees in 118 patients (average age, 13.9 ± 3.4 years; 48% female patients) with PI were identified. Within this cohort, 67% were treated surgically and 53% had OD. No association was identified between osteochondral injury and age, sex, body mass index, symptom duration, LTI angle, LPI angle, dTT-TG distance, pTT-TG distance, or number of dislocations. An increased sulcus angle (more dysplasia) showed a statistically significant association with osteochondral pathology (P = .021), and higher sulcus angles were statistically significantly associated with acute osteochondral fracture compared with chondral injury (P = .001). CONCLUSIONS Using quantitative analysis of trochlear dysplasia, this study identified a significant association between trochlear dysplasia (sulcus angle) and the incidence of OD in our cohort of patients with PI. The frequency of dislocation or subluxation and patient demographic characteristics were not significantly associated with OD. LEVEL OF EVIDENCE Level III, retrospective prognostic study.

Abstract
BACKGROUND Previous literature has suggested that primary acetabular labral reconstruction leads to lower secondary surgery rates than does labral repair for patients aged ≥40 years. PURPOSE To report minimum 2-year patient-reported outcome (PRO) scores, survivorship, and secondary surgeries in patients aged ≥40 years who underwent primary hip arthroscopy with labral reconstruction compared with a propensity-matched primary labral repair group. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for patients who underwent a primary hip arthroscopy for femoroacetabular impingement syndrome between January 2014 and June 2018. Patients aged ≥40 years who underwent a labral reconstruction or a labral repair and had preoperative and minimum 2-year PROs for the modified Harris Hip Score, Nonarthritic Hip Score, and visual analog scale (VAS) for pain were included. Patients with previous ipsilateral hip conditions and surgery, Tönnis grade >1, hip dysplasia, or workers' compensation status were excluded. Patients in the reconstruction group were propensity matched 1:2 to patients in the repair group based on age, sex, and body mass index. Secondary surgeries and achievement of the minimal clinically important difference (MCID), patient acceptable symptom state (PASS), and maximum outcome improvement (MOI) were recorded. RESULTS A total of 53 and 106 hips were included in the labral reconstruction and repair groups, respectively. The average follow-up time was 37.6 months. The average ages for the reconstruction and repair groups were 48.01 ± 5.4 years and 48.61 ± 6.0 years, respectively. Both groups achieved significant improvements in all PROs at a minimum of 2 years, with similar achievements of MCID, PASS, and MOI, and comparable secondary surgery rates. CONCLUSION Patients aged ≥40 years who received primary labral repair and primary labral reconstruction achieved similar significant improvements in all PROs, VAS pain, and patient satisfaction at the minimum 2-year follow-up, with comparable rates of secondary surgeries and achieving MCID, PASS, and MOI. Based on these findings, labral repair remains the gold standard treatment for viable labrum in this population group, while reconstruction is a useful alternative for irreparable labrum.

Abstract
BACKGROUND Access to quality health care and treatment outcomes can be affected by patients' socioeconomic status (SES). PURPOSE To evaluate the effect of patient SES on patient-reported outcome measures (PROMs) after arthroscopic hip surgery. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Demographic, radiographic, and intraoperative data were prospectively collected and retrospectively reviewed on all patients who underwent hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tear between February 2008 and September 2017 at one institution. Patients were divided into 4 cohorts based on the Social Deprivation Index (SDI) of their zip code. SDI is a composite measure that quantifies the level of disadvantage in certain geographical areas. Patients had a minimum 2-year follow-up for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), International Hip Outcome Tool-12, and visual analog scale (VAS) for both pain and satisfaction. Rates of achieving the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) were calculated for the mHHS, NAHS, and VAS pain score. Rates of secondary surgery were also recorded. RESULTS A total of 680 hips (616 patients) were included. The mean follow-up time for the entire cohort was 30.25 months. Division of the cohort into quartiles based on the SDI national averages yielded 254 hips (37.4%) in group 1, 184 (27.1%) in group 2, 148 (21.8%) in group 3, and 94 (13.8%) in group 4. Group 1 contained the most affluent patients. There were significantly more men in group 4 than in group 2, and the mean body mass index was greater in group 4 than in groups 1 and 2. There were no differences in preoperative radiographic measurements, intraoperative findings, or rates of concomitant procedures performed. All preoperative and postoperative PROMs were similar between the groups, as well as in the rates of achieving the MCID or PASS. No differences in the rate of secondary surgeries were reported. CONCLUSION Regardless of SES, patients were able to achieve significant improvements in several PROMs after hip arthroscopy for FAIS and labral tear at the minimum 2-year follow-up. Additionally, patients from all SES groups achieved clinically meaningful improvement at similar rates.

Abstract
CASE A 43-year-old female patient complained of pain in the right hip. The diagnoses of hip dysplasia, ischiofemoral impingement (IFI), femoroacetabular (FAI) cam-type morphology, and labral tear were made. The patient underwent hip arthroscopy with labral reconstruction for an irreparable labral tear and cam-morphology correction, and hip endoscopy for shelf procedure and ischiofemoral decompression. Favorable outcomes were reported at 1-year follow-up. CONCLUSION Hip arthroscopy for FAI cam-type morphology with labral reconstruction and concomitant hip endoscopy for shelf and ischiofemoral decompression seem to be safe for the treatment of active young adult patients with FAI cam-type morphology, irreparable labral tear, dysplasia, and IFI diagnoses. Nevertheless, the results presented should not be extrapolated as this is a case report.

Abstract
BACKGROUND Return to sports (RTS) and patient-reported outcomes (PROs) for high-level athletes after bilateral hip arthroscopy have not been well established. PURPOSE (1) To report minimum 2-year PROs and RTS rates in high-level athletes who underwent staged bilateral primary hip arthroscopies and (2) to compare clinical results against a propensity-matched control group of high-level athletes who underwent unilateral primary hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for high-level athletes (professional, college, or high school) who underwent staged bilateral hip arthroscopy for femoroacetabular impingement syndrome between September 2009 and October 2018. Inclusion criteria were preoperative and minimum 2-year follow-up for modified Harris Hip Score, Non-arthritic Hip Score, Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and visual analog scale for pain. Exclusion criteria were Tönnis grade >1, hip dysplasia (lateral center-edge angle <18°), and previous ipsilateral hip surgery/conditions. Rates of achieving the minimal clinically important difference (MCID), patient acceptable symptomatic state (PASS), and maximum outcome improvement satisfaction threshold were recorded in addition to RTS. These athletes were then propensity matched in a 1:3 ratio to high-level athletes who underwent unilateral arthroscopy for comparison. Outcomes were compared among the first hip of the study group, the second hip of the study group, and the control group. RESULTS A total of 74 high-level athletes who underwent bilateral hip arthroscopy met the inclusion criteria, and follow-up was available for 68 (91.9%) at 58.9 ± 24.5 months (mean ± SD). Athletes undergoing bilateral hip arthroscopy returned to sports at a high rate (81.7%), demonstrated significant improvements in all recorded PROs, and achieved the MCID and PASS for the HOS-SSS at rates of 80.9% and 64.7%, respectively. PROs, RTS rate, and rates of achieving the MCID and PASS for the HOS-SSS were similar when the bilateral study group was compared with the unilateral control group (P > .05). CONCLUSION High-level athletes who undergo staged bilateral primary hip arthroscopy for femoroacetabular impingement syndrome may expect favorable PROs and RTS rates at minimum 2-year follow-up. These results were comparable with those of a propensity-matched control group of high-level athletes who underwent unilateral primary hip arthroscopy.

Abstract
BACKGROUND Outcomes of revision hip arthroscopy in the athletic population have not been well established. PURPOSE (1) To report clinical outcomes for high-level athletes undergoing revision hip arthroscopy in the setting of femoroacetabular impingement syndrome (FAIS) or labral tears and (2) to compare these outcomes against a propensity-matched group of high-level athletes undergoing primary hip arthroscopy. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data for professional, college, and high school athletes were prospectively collected and retrospectively reviewed between January 2012 and October 2018. Patients were included if they underwent revision or primary hip arthroscopy and had preoperative and minimum 2-year patient-reported outcome (PRO) scores for modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score Sports-Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain. The findings and outcomes of revision athletes were compared with a propensity-matched control group of high-level athletes undergoing primary hip arthroscopy. RESULTS A total of 32 hips (29 patients) undergoing revision hip arthroscopy and 92 hips (88 patients) undergoing primary hip arthroscopy were included in our final analysis with a median follow-up time of 29.5 months (95% CI, 27.2-32.1 months) and 36.5 months (95% CI, 33.5-37.7 months), respectively. Athletes undergoing revision surgery showed significant improvement in all recorded PRO measurements and achieved patient acceptable symptomatic state (PASS) and minimal clinically important difference (MCID) for mHHS at high rates (80.6% and 83.9%, respectively). When compared with a propensity-matched primary control group, patients undergoing revision surgery demonstrated lower preoperative and postoperative scores for mHHS, NAHS, and HOS-SSS, but the magnitude of improvement in functional scores was similar between groups. Athletes undergoing revision surgery achieved PASS for HOS-SSS at lower rates than the control group (P = .005), and they were less likely to attempt to return to sport compared with the control group (62.5% vs 87.0%; P < .01). CONCLUSION Revision hip arthroscopy is a viable treatment option to improve PROs in high-level athletes at minimum 2-year follow-up. The study group showed significant improvement in functional scores and a high rate of successful outcomes. They experienced similar magnitude of improvement as that of a propensity-matched control group; however, they achieved lower postoperative PRO scores and attempted to return to sport at lower rates.

Abstract
BACKGROUND High-level athletes (HLAs) have been shown to have better short-term outcomes than nonathletes (NAs) after hip arthroscopy. PURPOSE (1) To report midterm outcomes of HLAs after primary hip arthroscopy and (2) to compare their results with a propensity-matched cohort of NA patients. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed between February 2008 and November 2015 for HLAs (professional, college, or high school) who underwent primary hip arthroscopy in the setting of femoroacetabular impingement syndrome (FAIS). HLAs were included if they had preoperative, minimum 2-year, and minimum 5-year follow-up data for the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), and Hip Outcome Score Sports-Specific Subscale (HOS-SSS). Radiographic and intraoperative findings, surgical procedures, patient-reported outcomes (PROs), patient acceptable symptomatic state (PASS), minimal clinically important difference (MCID), and return to sport were reported. The HLA study group was propensity-matched to a control group of NA patients for comparison. RESULTS A total 65 HLA patients (67 hips) were included in the final analysis with mean follow-up time of 74.6 ± 16.7 months. HLAs showed significant improvement in all PROs recorded, achieved high rates of MCID and PASS for mHHS (74.6% and 79.4%, respectively) and HOS-SSS (67.7% and 66.1%, respectively), and returned to sport at high rates (80.4%). When compared with the propensity-matched NA control group, HLAs reported higher baseline but comparable postoperative scores for the mHHS and NAHS. HLA patients achieved MCID and PASS for mHHS at similar rates as NA patients, but the HLA patients achieved PASS for HOS-SSS at higher rates that trended toward statistical significance (66.1% vs 48.4%; P = .07). NA patients underwent revision arthroscopic surgery at similar rates as HLA patients (14.9% vs 9.0%, respectively; P = .424). CONCLUSION Primary hip arthroscopy results in favorable midterm outcomes in HLAs. When compared with a propensity-matched NA control group, HLAs demonstrated a tendency toward higher rates of achieving PASS for HOS-SSS but similar arthroscopic revision rates at minimum 5-year follow-up.

Abstract
BACKGROUND No studies have compared outcomes and return to sport (RTS) after hip arthroscopic surgery between matched groups of male and female athletes with a minimum 2-year follow-up. PURPOSE (1) To report minimum 2-year postoperative patient-reported outcome (PRO) scores and the RTS rate for elite female athletes undergoing hip arthroscopic surgery for femoroacetabular impingement (FAI) and (2) to compare clinical results with a matched control group of elite male athletes. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data on all consecutive female athletes who underwent primary hip arthroscopic surgery performed at our institution between March 2009 and July 2018 were collected. Patients were eligible if they underwent hip arthroscopic surgery for labral tears or FAI and participated in collegiate or professional athletics within 1 year of surgery. Minimum 2-year postoperative PRO scores were collected for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), and visual analog scale (VAS) for pain as well as RTS status. The percentages of patients achieving the minimal clinically important difference (MCID) and patient acceptable symptomatic state were recorded. These patients were matched to elite male athletes for comparison. RESULTS A total of 73 female hips were included, with a mean follow-up of 65.1 ± 27.9 months. They demonstrated a significant improvement from preoperatively to latest follow-up on the mHHS, NAHS, HOS-SSS, and VAS (P < .05). When outcomes were compared with a control group of male athletes, female athletes demonstrated lower preoperative scores, similar postoperative scores, and a significantly greater magnitude of improvement (delta value) on the mHHS, NAHS, and VAS. Female athletes also achieved the MCID at higher rates than did male athletes for the HOS-SSS (85.1% vs 70.0%, respectively; P = .035) and NAHS (79.1% vs 62.9%, respectively; P = .037). RTS rates among patients who attempted were similar between the 2 groups (female: 75.4%; male: 83.1%; P = .409). CONCLUSION Elite female athletes undergoing primary hip arthroscopic surgery for FAI demonstrated a significant improvement in PRO scores and a high RTS rate. Female athletes exhibited a greater improvement in PRO scores (mHHS, NAHS, VAS) and achieved the MCID (HOS-SSS, NAHS) at higher rates compared with a control group of male athletes.

Abstract
BACKGROUND Labral reconstruction has shown promise for the treatment of irreparable labral tears in high-level athletes. The literature is scarce regarding outcomes and timing of return to sports (RTS) in these patients. PURPOSE (1) To report minimum 2-year patient-reported outcome (PRO) scores and RTS characteristics for high-level athletes undergoing primary labral reconstruction for irreparable labral tears and (2) to compare clinical results with a matched control group of athletes undergoing labral repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Data were prospectively collected and retrospectively reviewed for high school, college, and professional athletes who underwent a primary arthroscopic labral reconstruction between January 2010 and June 2018. Minimum 2-year PROs were compared for the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), and Hip Outcome Score-Sport Specific Subscale (HOS-SSS), as well as the visual analog scale (VAS) pain score, patient satisfaction, and RTS. The percentages of patients achieving the Patient Acceptable Symptom State (PASS) and minimal clinically important difference (MCID) for the mHHS (PASS, >74 points; MCID, >8 points) and HOS-SSS (PASS, >75 points; MCID, >6 points) were also recorded. These patients were propensity score matched in a 1:3 ratio to other high-level athletes undergoing labral repair. RESULTS A total of 17 high-level athletes with primary arthroscopic labral reconstruction were included with a median follow-up time of 37.1 months (95% CI, 37.2-60.3 months). They demonstrated significant improvement from preoperatively to the latest follow-up for mHHS, NAHS, HOS-SSS, and VAS for pain (P < .05). Further, patients achieved PASS/MCID for mHHS at high rates (PASS, 84.2%; MCID, 68.4%). Athletes were able to return to sport-specific training at a median of 3.33 months (95% CI, 3.07-4.71 months) and RTS at a median of 6.2 months (95% CI, 5.08-11.98 months). Fourteen (82.4%) of reconstructions and 29 (82.8%) of repairs either returned to sport or decided not to do so for reasons unrelated to the hip. PROs, RTS rate, and PASS/MCID rates were similar between the labral reconstruction group and a control labral repair group (P > .05). CONCLUSION Primary arthroscopic labral reconstruction for irreparable labral tears was associated with significant improvement in PROs and high rates of RTS in high-level athletes. These results were comparable with those of a control group of athletes undergoing labral repair.

Abstract
The shelf procedure is a treatment of acetabular dysplasia, with the aim of increasing weight-bearing acetabular coverage. Although several shelf techniques have been described, the endoscopic procedure with concomitant hip arthroscopy is a new, less invasive alternative. Outcomes following this procedure are scarce. The purpose of this study was to report short-term patient-reported outcomes (PROs) following concomitant hip arthroscopy and endoscopic modified shelf procedure in the setting of acetabular dysplasia and labral tears. Patients that met extraordinarily selective surgical indications and underwent the abovementioned surgery between February 2016 and October 2019 and had minimum 1-year follow-up were included. There were five females with a mean age of 40.18 ± 5.05 years and follow-up of 21.55 ± 8.68 months. The lateral center-edge angle increased from 15.80° to 23.20° (P = 0.003), and vertical center-edge angle increased from 16.60° to 23.60° (P < 0.001). The Tönnis angle decreased from 15.40° to 3.74° (P < 0.001). The alpha angle decreased from 58.46° to 40.70° (P < 0.001). PROs demonstrated significant improvement at latest follow-up (modified Harris Hip Score, P = 0.042; Non-Arthritic Hip Score, P < 0.001; Hip Outcome Score–Sports Specific Subscale, P = 0.035; Visual Analog Scale, P < 0.001; International Hip Outcome Tool-12, P = 0.043), and satisfaction was 8.60 ± 0.89. No secondary surgeries were reported. Concomitant hip arthroscopy and endoscopic modified shelf procedure appears to be a safe and effective procedure for patients with acetabular dysplasia and labral tears yielding favorable outcomes and satisfaction at short-term follow-up.

Abstract
BACKGROUND Heterotopic ossification (HO) commonly occurs after total hip arthroplasty (THA) and can adversely impact clinical outcomes. The purpose of this study is to propose a more reliable HO grading method that is better predictive of patient-reported outcomes (PROs) after THA than the Brooker classification. METHODS 513 THAs (62 ± 10 years old) were reviewed. The incidence and grade of HO was evaluated using the Brooker grading system and a simplified biplanar classification system (grade 1: ⩾1 cm between bone on both anteroposterior and lateral views, grade 2: <1 cm between bone on either view). The modified Harris Hip Score (mHHS), Forgotten Joint Score (FJS), and visual analogue scale (VAS) for pain were collected at minimum of 2 years after surgery and were compared between HO grades using multiple regression models. RESULTS The incidence of HO varied by Brooker grade (grade 1, 23.4%; grade 2, 22.4%; grade 3, 7.2%; grade 4, 0%) and biplanar grade (grade 1: 45.6%; grade 2: 7.4%). The biplanar classification demonstrated higher interobserver reliability than the Brooker classification (κ = 0.95 and 0.91, respectively). Brooker grade 3 HO decreased the mHHS by 6.5 (standard error: 2.7) but did not have a significant effect on FJS or VAS. Biplanar grade 2 HO decreased the mHHS by 9.9 (standard error: 2.7), the FJS by 12.9 (standard error: 4.51) and increased the VAS pain score by 0.81 (standard error: 0.35). The Cox test was used to compare the fit of regression models and determined the biplanar classification was a significantly better predictor than the Brooker classification (p < 0.001). CONCLUSIONS Biplanar grade 2 HO had a significant negative influence on PROs. Contrary to previous literature, these results show clinical significance of non-bridging HO. Compared with the Brooker classification, the biplanar classification has greater interobserver reliability and is more predictive of outcomes after THA.

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

[PMID: 33887416 DOI: 10.1016/j.arthro.2021.03.063] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 03/22/2021] [Accepted: 03/23/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To review the existing literature in order to determine the effect of hip capsule repair on outcomes after hip arthroscopy for femoroacetabular impingement syndrome. METHODS This study used Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to find articles by using PubMed and Embase. Included studies were Level I through III studies that focused on patient outcomes as a function of hip capsular treatments: capsulotomy repair, partial repair, plication, and unrepaired capsulotomies. The Methodological Index for Non-randomized Studies was used for quality assessment of clinical outcome studies. After applying inclusion and exclusion criteria, a total of 16 comparative outcome studies evaluating 2,996 hips were included; they evaluated the following capsular management techniques: complete repair (n = 1,112, 37.1%), partial repair (n = 32, 1.1%), plication (n = 223, 7.4%), and unrepaired capsulotomy (n = 1629, 54.4%). RESULTS Of the 16 studies, 13 included patient-reported outcome scores (PROs), 3 included imaging outcomes data, and 2 reported on reoperation. Of the studies, 10 directly compared patient-reported outcomes between a capsular repair group and an unrepaired group. Of the 10 studies that directly compared PROs between a group with unrepaired capsulotomy and a group with capsular repair, 8 studies demonstrated statistically significantly better PROs in the repaired group compared to the unrepaired group, and 2 studies found no difference between the groups. Reoperation rates demonstrated mixed results between groups, and no difference was found in regard to imaging outcomes. CONCLUSIONS Midterm outcome studies suggest that capsular repair is safe and effective in patients without arthritis who are undergoing hip arthroscopy, and it may result in superior PROs compared with those found after unrepaired capsulotomy. Studies consistently demonstrate similar or superior outcomes in cohorts after capsular repair compared to unrepaired capsulotomy, and no studies reported superior results in unrepaired capsulotomy patients. LEVEL OF EVIDENCE Level IV, systematic review of Level I through Level III studies.

Medial meniscal extrusion greater than 4 mm reduces medial tibiofemoral compartment contact area: a biomechanical analysis of tibiofemoral contact area and pressures with varying amounts of meniscal extrusion. Knee Surg Sports Traumatol Arthrosc 2021; 29:3124-3132. [PMID: 33221933 DOI: 10.1007/s00167-020-06363-0] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 11/02/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE The primary objective of this study is to evaluate the contact areas, contact pressures, and peak pressures in the medial compartment of the knee in six sequential testing conditions. The secondary objective is to establish how much the medial meniscus is able to extrude, secondary to soft tissue injury while keeping its roots intact. METHODS Ten cadaveric knees were dissected and tested in six conditions: (1) intact meniscus, (2) 2 mm extrusion, (3) 3 mm extrusion, (4) 4 mm extrusion, (5) maximum extrusion, (6) capsular based meniscal repair. Knees were loaded with a 1000-N axial compressive force at 0°, 30°, 60°, and 90° for each condition. Medial compartment contact area, average contact pressure, and peak contact pressure data were recorded. RESULTS When compared to the intact state, there was no statistically significant difference in medial compartment contact area at 2 mm of extrusion or 3 mm of extrusion (n.s.). There was a statistically significant decrease in contact area compared to the intact state at 4 mm (p = 0.015) and maximum extrusion (p < 0.001). The repair state was able to improve medial compartment contact area, and there was no statistically significant difference between the repair and the intact states (n.s.). No significant differences were found in the average contact pressure between the repair, intact, or maximum extrusion conditions at any flexion angle (n.s.). No significant differences were found in the peak contact pressure between the repair, intact, or maximum extrusion conditions at any flexion angle (n.s.). CONCLUSION In this in vitro model, medial meniscus extrusion greater than 4 mm reduced medial compartment contact area, but meniscal extrusion did not significantly increase pressure in the medial compartment. Additionally, meniscal centralization was effective in restoring the medial tibiofemoral contact area to intact state when the meniscal extrusion was secondary to meniscotibial ligament injury. The diagnosis of meniscal extrusion may not necessarily involve meniscal root injury. Since it is known that meniscal extrusion greater than 3 or 4 mm has a biomechanical impact on tibiofemoral compartment contact area and pressures, specific treatments can be established. Centralization restored medial compartment contact area to the intact state.

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.

Limited lumbopelvic mobility does not influence short-term outcomes after primary hip arthroscopy: a propensity-matched controlled study. J Hip Preserv Surg 2021; 8:177-184. [PMID: 35145715 PMCID: PMC8825469 DOI: 10.1093/jhps/hnab056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 06/29/2021] [Accepted: 07/19/2021] [Indexed: 12/04/2022] Open
Abstract
There is a paucity of literature investigating the effect of lumbopelvic mobility on patient-reported outcome scores (PROs) after primary hip arthroscopy. The purpose of this study was (i) to report minimum 1-year PROs in patients with limited lumbopelvic mobility (LM) who underwent primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and (ii) to compare clinical results with a propensity-matched control group of patients with normal lumbopelvic mobility (NM). Data were reviewed for surgeries performed between November 2019 and March 2020. Patients were considered eligible if they received a primary hip arthroscopy for FAIS in the setting of LM (seated to standing change in sacral slope ≤ 10°). LM patients were propensity-matched to a control group of patients with normal lumbopelvic motion (seated to standing change in sacral slope > 10°) for comparison. A total of 17 LM and 34 propensity-matched NM patients were included in the study. LM patients showed significant improvement in all outcome measures and achieved the minimum clinically important difference (MCID) and patient acceptable symptomatic state (PASS) at high rates for modified Harris Hip Score (MCID: 94% and PASS: 82%) and International Hip Outcome Tool-12 (iHOT-12; MCID: 94% and iHOT-12: 76%). When LM patients were compared to a propensity-matched control group of NM patients, they demonstrated similar postoperative PROs and rates of achieving MCID/PASS. LM patients who undergo primary hip arthroscopy may expect favorable short-term PROs at minimum 1-year follow-up. These results were comparable to a control group of NM patients.

Arthroscopy 2021; 37:2582-2588. [PMID: 33771692 DOI: 10.1016/j.arthro.2021.03.030] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 03/03/2021] [Accepted: 03/10/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the relation between the femoral intercondylar index, tibial slope, and meniscal slope between 3 different groups of skeletally immature patients: primary anterior cruciate ligament (ACL) injury (group 1), ACL reconstruction failure (group 2), and control group, without an ACL injury history (group 3). METHODS This retrospective study evaluated magnetic resonance imaging scans of the knees of 605 skeletally immature patients obtained between 2015 and 2020. The inclusion criteria were as follows: patients younger than 16 years who were skeletally immature and underwent knee magnetic resonance imaging for any reason. RESULTS A total of 605 skeletally immature patients were included in the study. The ratio of patients with ACL injury (cases) to those without ACL injury (controls) was 1:2.5. Patients with ACL injury had significantly greater medial meniscal slope and lateral meniscal slope values than the control group without ACL injury (P < .001). There was no statistically significant difference between patients with primary ACL injury and those with ACL reconstruction failure for all measured variables. CONCLUSIONS The medial and lateral meniscal slope values were significantly higher in skeletally immature patients with ACL injury than in the control group of patients without ACL injury. There was no statistically significant difference in measurements of the femoral intercondylar index, lateral meniscal slope, medial meniscal slope, lateral tibial slope, or medial tibial slope between patients with primary injury and those with ACL reconstruction failure. LEVEL OF EVIDENCE Level III, retrospective comparative trial.
