Insights
Delayed anterior cruciate ligament reconstruction (ACLR) in children is linked to socioeconomic factors and increased injury risk. System-level delays in care significantly impact outcomes, highlighting disparities in pediatric orthopaedic treatment.
Area of Science:
- Pediatric Orthopaedics
- Sports Medicine
- Health Services Research
Background:
- Delayed anterior cruciate ligament reconstruction (ACLR) in pediatric patients correlates with worsening intra-articular damage.
- Existing research indicates disparities in pediatric orthopaedic care access.
- The influence of social determinants of health on surgical delays and functional recovery post-ACLR remains unclear.
Purpose of the Study:
- To investigate the association between sociodemographic factors, structural determinants, and delayed pediatric ACLR.
- To examine the relationship between these determinants and intra-articular injury severity.
- To assess the impact on postoperative functional outcomes.
Main Methods:
- A retrospective cohort study of 443 pediatric patients undergoing ACLR.
- Analysis of factors including race/ethnicity, insurance, and neighborhood deprivation (Childhood Opportunity Index).
- Outcomes measured: delay to surgery (>120 days), cartilage injury, meniscal tears, return to sport, hop test symmetry, and graft failure.
Main Results:
- 38.6% of patients experienced prolonged delay (>120 days) from presentation to surgery.
- Minority race/ethnicity, public insurance, and lower neighborhood opportunity were linked to delayed ACLR.
- Prolonged delay correlated with increased odds of high-grade cartilage injury.
- Public insurance was associated with greater hop test asymmetry postoperatively.
Conclusions:
- Disparities in pediatric ACLR are significantly influenced by system-level delays after initial presentation.
- These delays are associated with a progressively higher risk of cartilage damage.
- Addressing system-level barriers is crucial for equitable pediatric orthopaedic care.
Background:
Delayed anterior cruciate ligament reconstruction (ACLR) in pediatric patients is associated with progressive intra-articular injury. Although disparities in access to orthopaedic care have been reported, it remains unclear whether structural determinants of health influence postpresentation surgical delay and downstream functional recovery.
Purpose:
To determine whether sociodemographic and structural determinants are associated with prolonged postpresentation delay to pediatric ACLR and with intra-articular injury severity and postoperative functional outcomes.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
The records of 443 pediatric patients who underwent ACLR (2013-2025) at an urban academic referral center with a pediatric orthopaedic urgent care were reviewed. Exposures included race/ethnicity, insurance type, and neighborhood deprivation (Childhood Opportunity Index [COI]). Delay was defined as time from first orthopaedic presentation to surgery, with prolonged delay defined as >120 days. Outcomes included high-grade cartilage injury (Outerbridge grade 3 or 4), meniscal tear presence, failure to return to sport (≥365 days of follow-up), hop test symmetry, isometric strength symmetry, and graft failure. Multivariable regression models were adjusted for race/ethnicity, age, sex, insurance, and national COI.
Results:
The median time from injury to presentation was 5 days, while the median postpresentation time to surgery was 101 days; 38.6% experienced prolonged delay. In adjusted logistic regression, non-Hispanic Black, Hispanic, and other/unknown race/ethnicity; public insurance; and lower neighborhood opportunity were each independently associated with prolonged delay. Continuous postpresentation delay was independently associated with increased odds of high-grade cartilage injury (OR, 1.004 per day; 95% CI, 1.000-1.008; P = .048). Among patients with ≥365 days of follow-up (n = 228), public insurance was not independently associated with failure to return to sport (OR, 1.69; P = .398). Among those completing functional testing (n = 150), public insurance (β = +9.14; P = .046), higher national COI (β = +0.14 per unit; P = .045), and male sex (β = +9.59; P = .010) were each independently associated with greater hop test asymmetry, whereas no independent associations were observed for isometric strength symmetry or graft failure.
Conclusion:
Disparities in pediatric ACLR are driven primarily by postpresentation system-level delays and are associated with an incrementally greater risk of cartilage injury.
