Are Neighborhood Conditions Associated With Surgical Delays and Meniscus Tears in Children and Adolescents Undergoing ACL Reconstruction?

BACKGROUND: Markers of a patient's social determinants of health, including healthcare insurance and median household income based on ZIP Code, have been associated with the interval between injury and ACL reconstruction (ACLR) as well as the presence of concomitant meniscus tears in children and adolescents. However, the aforementioned surrogate indicators of a patient's social determinants of health may not reflect all socioeconomic and healthcare resources affecting the care of ACL injuries in children and adolescents. The use of multivariate indices such as the Child Opportunity Index (COI) may help to better identify patients at risk for increased risk for delay between ACL injury and surgery, as well as the incidence of meniscus tears at the time of surgery. The COI is a summative measure of 29 indicators that reflect neighborhood opportunities across three domains: education, health and environment, and social and economic factors. COI scores range from 0 to 100 (100 being the highest possible score), as well as five categorical scores (very low, low, moderate, high, and very high) based on quintile rankings. QUESTIONS/PURPOSES: To investigate the relationship between neighborhood conditions and the treatment of ACL injuries in children and adolescents via the COI, we asked: (1) Is a lower COI score associated with a longer delay between ACL injury and surgery? (2) Does a higher proportion of patients with lower COI scores have meniscus tears at the time of ACLR? METHODS: In this retrospective, comparative study, we considered data from 565 patients, 18 years or younger, who underwent primary ACLR at an urban, tertiary children's hospital between 2011 and 2021. Of these patients, 5% (31 of 565) did not have a clearly documented date of injury, 2% (11 of 565) underwent revision reconstructions, and 1% (5 of 565) underwent intentionally delayed or staged procedures. Because we specifically sought to compare patients who had low or very low COI scores (lowest two quintiles) with those who had high or very high scores (highest two quintiles), we excluded 18% (103 of 565) of patients with moderate scores. Ultimately, 73% (415 of 565) of patients with COI scores in either the top or bottom two quintiles were included. Patient addresses at the time of surgery were used to determine the COI score. There were no differences between the groups in terms of gender. However, patients with high or very high COI scores had a lower median (IQR) age (15 years [2.6] versus 17 years [1.8]; p < 0.001) and BMI (23 kg/m 2 [6.1] versus 25 kg/m 2 [8.8]; p < 0.001), were more commonly privately insured (62% [117 of 188] versus 22% [51 of 227]; p < 0.001), and had a higher proportion of patients identifying as White (67% [126 of 188] versus 6.2% [14 of 227]; p < 0.001) compared with patients with low or very low COI scores. Medical records were reviewed for demographic, preoperative, and intraoperative data. Univariate analyses focused on the relationship of the COI and interval between injury and surgery, frequency of concomitant meniscus tears, and frequency of irreparable meniscus tears treated with partial meniscectomy. Multivariable regression analyses were used to determine factors that were independently associated with delayed surgery (longer than 60 and 90 days after injury), presence of concomitant meniscal injuries, and performance of meniscectomy. Multivariable models included insurance and race or ethnicity to determine whether COI was independently associative after accounting for these variables. RESULTS: Patients with a high or very high COI score had surgery earlier than those with a low or very low COI score (median [IQR] 53 days [53] versus 97 days [104]; p < 0.001). After adjusting for insurance and race/ethnicity, we found that patients with a low or very low COI score were more likely than patients with a high or very high COI score to have surgery more than 60 days after injury (OR 2.1 [95% CI 1.1 to 4.0]; p = 0.02) or more than 90 days after injury (OR 1.8 [95% CI 1.1 to 3.4]; p = 0.04). Furthermore, patients with low or very low COI scores were more likely to have concomitant meniscus tears (OR 1.6 [95% CI 1.1 to 2.5]; p = 0.04) compared with patients with high or very high COI scores. After controlling for insurance, race/ethnicity, time to surgery, and other variables, there was no association between COI and meniscectomy (OR 1.6 [95% CI 0.9 to 2.8]; p = 0.12) or presence of a chondral injury (OR 1.7 [95% CI 0.7 to 3.9]; p = 0.20). CONCLUSION: As the COI score is independently associated with a delay between ACL injury and surgery as well as the incidence of meniscus tears at the time of surgery, this score can be useful in identifying patients and communities at risk for disparate care after ACL injury. The COI score or similar metrics can be incorporated into medical records to identify at-risk patients and dedicate appropriate resources for efficient care. Additionally, neighborhoods with a low COI score may benefit from improvements in the availability of additional and/or improved resources. Future studies should focus on the relationship between the COI score and long-term patient-reported functional outcomes after ACL injury, identification of the specific timepoints in care that lead to delayed surgery for those with lower COI scores, and the impact of community-based interventions in improving health equity in children with ACL injury.

Epidemiology of pediatric cartilage restoration procedures in the United States: insurance and geography play a role.

OBJECTIVES: The purpose of this study is to analyze the epidemiology of children and adolescents undergoing osteochondral autograft transplantation (OAT), osteochondral allograft transplantation (OCA), and autologous chondrocyte implantation (ACI) in the United States. METHODS: The Pediatric Health Information System, a national database consisting of 49 children's hospitals, was queried for all patients undergoing OAT, OCA, and ACI between 2012 and 2018. Demographic information was collected for each subject. United States Census guidelines were used to categorize hospitals geographically. Univariate analysis was followed by purposeful entry multivariate regression to adjust for confounding factors. RESULTS: A total of 809 subjects with a mean age of 15.4 ± 2.4 years were included in the analysis. Of these, 48.6% underwent OCA, 41.9% underwent OAT, and 9.5% underwent ACI. After adjusting for confounders in a multivariate model, ACI was 3.6 times more likely to be performed in patients with private insurance than those that were publicly insured (95% CI 1.6-8.0, p = 0.002). Furthermore, a patient in the Northeast was 33.1 times more likely to undergo ACI than in the West (95% CI 4.5-246.1, p = 0.001). OAT was performed most frequently in the West and Midwest (52.4% and 51.8% of the time, respectively; p < 0.001). CONCLUSION: In the United States, there is substantial variation in the procedures performed for cartilage restoration in children and adolescents. Though ACI is the least commonly selected operation overall, it is significantly more likely to be performed on patients with private insurance and those in the Northeast.

Is Preferred Language Other Than English Associated With Delayed Surgery After ACL Injury in Children and Adolescents?

BACKGROUND: Previous studies have investigated the impact of social determinants of health, such as the type of healthcare insurance and household income, on children and adolescents with ACL tears. However, despite the increasing incidence of ACL injury in young patients and a substantial proportion of families who may prefer languages other than English, the relationship between language and clinical care remains unclear. QUESTIONS/PURPOSES: To investigate the relationship between language and the care of children and adolescents with ACL tears, we asked: (1) Is a preferred language other than English (PLOE) associated with a delay between ACL injury and surgery? (2) Is a PLOE associated with a greater odds of a patient experiencing a meniscal tear and undergoing a meniscectomy than in those who prefer English? METHODS: We treated 591 patients surgically for ACL injuries between 2011 and 2021. Of those, we considered patients aged 18 years or younger who underwent primary ACL reconstruction for this retrospective, comparative study. Five percent (31 of 591) of patients were excluded because the date of injury was not clearly documented, 2% (11 of 591) were revision reconstructions, and 1% (6 of 591) underwent procedures that were intentionally delayed or staged, leaving 92% (543 of 591) for analysis. The mean age was 16 ± 2 years, and 51% (276 of 543) of patients were boys. The family's preferred language was noted, as were demographic data, time between injury and surgery, and intraoperative findings. A language other than English was preferred by 21% (113 of 543) of patients. Of these, 94% (106 of 113) preferred Spanish. In a univariate analysis, we used independent-samples t-tests, Mann-Whitney U-tests, and Fisher exact tests, as appropriate. Purposeful-entry multivariable regression analyses were used to determine whether PLOE was associated with increased time to surgery, concomitant meniscus injury, or performance of meniscectomy while adjusting for confounding variables. Variables were included in multivariable models if they met the threshold for statistical significance in univariate testing (p < 0.05). RESULTS: The median time between injury and ACL reconstruction was shorter in families who preferred English compared with those with a PLOE (69 days [IQR 80] versus 103 days [IQR 107)]; p < 0.001). After controlling for potentially confounding variables like insurance and age, we found that patients whose families had a PLOE had greater odds of undergoing surgery more than 60 days after injury (OR 2.2 [95% CI 1.3 to 3.8]; p = 0.005) and more than 90 days after injury (OR 1.8 [95% CI 1.1 to 2.8]; p = 0.02). After controlling for insurance, age, and other factors, PLOE was not associated with surgical delay beyond 180 days, concomitant meniscal tears, or performance of meniscectomy. CONCLUSION: In this study of children and adolescents undergoing primary ACL reconstruction, patients whose families prefer a language other than English experienced a longer delay between injury and surgery. In areas with a large proportion of families with a PLOE, partnerships with primary care clinicians, emergency departments, schools, athletic teams, and community organizations may improve efficiency in the care of children with ACL injuries. Clinicians proficient in other languages, reliable interpreter services, and translated references and resources may also be impactful. Our results suggest a need for further research on the experiences, needs, and long-term outcomes of these patients, as well as the association of preferred language with results after surgery.

Reoperation After Osteochondral Autograft and Allograft Transfer in the Pediatric Knee.

Osteochondral autograft (OAU) transfer and osteochondral allograft (OAL) transfer are options for treating sizable articular cartilage lesions in the knee, but there is little evidence to support one technique over another. The goal of this study is to compare the rate of reoperation among children and adolescents undergoing OAU or OAL of the knee. In this retrospective cohort study, the Pediatric Health Information System, a national database consisting of 49 children's hospitals, was queried for all patients undergoing OAU and OAL between 2012 and 2018. A total of 732 subjects with a mean age of 15.4±2.4 years were included. Of these, 393 (53.7%) initially underwent OAL and 339 (46.3%) underwent OAU. The overall reoperation rate was 144 of 732 (19.7%) at a median of 6.6 months (range, 0.6-53.5 months) after the index operation. This rate was similar for OAL and OAU. For 18 subjects (2.5%), OAU, OAL, or autologous chondrocyte implantation (ACI) was performed at the time of revision surgery. When analyzing only open procedures, we found that the reoperation rate was 25.5% for open OAU compared with 16.5% for open OAL (P=.03). When adjusting for covariates in multivariate regression, we found that those who underwent open OAU had 1.7 times higher odds of requiring a future reoperation than those who underwent open OAL (95% CI, 1.1-2.8; P=.04). Although the rate of reoperation after OAU or OAL among children and adolescents is relatively high, few require revision OAU, OAL, or ACI. Patients undergoing open OAU have higher odds of ultimately requiring reoperation than those undergoing open OAL. [Orthopedics. 2022;45(6):378-383.].

Predictors of Arthrofibrosis After Pediatric Anterior Cruciate Ligament Reconstruction: What Is the Impact of Quadriceps Autograft?

BACKGROUND: Recent literature on arthrofibrosis after anterior cruciate ligament reconstruction (ACLR) in children and adolescents is limited, especially with regards to quadriceps tendon (QT) autograft. The purpose of this study was to identify predictors of arthrofibrosis after ACLR, with attention to the impact of graft type. METHODS: Patients that underwent primary ACLR at a tertiary children's hospital were reviewed for this retrospective case-control study. Those with multiligament reconstructions, lateral extra-articular tenodesis procedures, allografts, or a modified MacIntosh reconstruction were excluded. Arthrofibrosis was defined as a deficit of 10 degrees of extension and/or 20 degrees of flexion at 3 months after ACLR. Univariate analysis was followed by purposeful entry logistic regression to adjust for confounding factors. RESULTS: A total of 378 patients (mean age 15.9±1.7 y, 49.7% female) were included in the analysis, of which there were 180 patellar tendon (PT), 103 hamstrings tendon (HT), and 95 QT grafts. The rate of arthrofibrosis was 1.9% for HT, 6.3% for QT, and 10.0% for PT (P=0.04). Females developed arthrofibrosis more frequently than males (10.6% vs. 3.2%, P=0.004). Those that ultimately experienced this complication had lower median flexion at 6 weeks after ACLR (88 vs. 110 degrees, P<0.001). In multivariate analysis, PT graft raised the odds of arthrofibrosis 6.2 times compared to HT [95% confidence interval (CI): 1.4-27.6, P=0.02], but there were no significant differences between QT and other grafts. Females were at 4.2 times higher odds than males (95% CI: 1.6-10.8; P=0.003). Patients that were unable to attain 90 degrees of flexion 6 weeks after ACLR had 14.7 times higher odds of eventually developing arthrofibrosis (95% CI: 5.4-39.8; P<0.001). Finally, those with an extension deficit of ≥5 degrees 6 weeks after ACLR had 4.7 times higher odds of experiencing this complication (95% CI: 1.8-12.2, P=0.001). CONCLUSION: The rate of arthrofibrosis with QT autograft is 6.3% after pediatric ACLR. PT autograft, female sex, and motion deficits at 6 weeks after ACLR were predictive of arthrofibrosis in children and adolescents. LEVEL OF EVIDENCE: Level III-prognostic study.
