Purpose: This is the second phase in an investigation of the psychosocial impact of orthopedic surgery on adolescents. What are the core psychosocial factors that shape the experience of adolescent patients aged 11–18 who are undergoing orthopedic surgery? Methods: Two 43-question surveys (preoperative and postoperative) were developed as modified versions of the survey used in phase 1. The preoperative survey was administered 2 weeks before surgery. The postoperative survey was administered 6 weeks later. Responses were collected from free-response and Likert-scale questions exploring patient–physician relationships, office visits/hospital stays, family, peers, academics, sports, and surgical expectations. The survey was administered prospectively to patients aged 11–18 undergoing limb lengthening/reconstruction, pediatric, spine, sports, or hand/upper extremity orthopedic surgery. In all, 135 patients were identified; 105 were enrolled and completed both surveys. Results: There were some statistically significant changes in responses to questions regarding office visits/hospital stays, patient–physician relationships, friends/community, academic performance, and expectations for surgical experience throughout the perioperative period. There were no statistically significant changes in responses to questions regarding the role of parent/family and sports. There was no statistically significant difference between the female and male genders or between age groups in any of the domains. Overall statistical significance in this study did not consistently correlate to clinical significance. Conclusion: Adolescents require psychosocial support from their surgeons, caregivers, and peers in addition to respect for their independence and personal needs. Level of evidence: Level II.

Background: Osteochondritis dissecans (OCD) of the knee is a focal idiopathic alteration of subchondral bone and/or its precursor with risk for instability and disruption of adjacent cartilage. Treatment options focused on preventing premature osteoarthritis vary depending on multiple patient and lesion characteristics, including lesion mobility. Purpose: To differentiate lesion mobility before arthroscopy using a multivariable model that includes patient demographic characteristics and physical examination findings. Study Design: Cohort study (Diagnosis); Level of evidence, 2. Methods: Demographic, preoperative physical examination, and radiographic data were collected from a multicenter national prospective cohort of patients with OCD of the knee. Inclusion criteria included patients <19 years of age and patients with arthroscopically confirmed mobility status based on the Research on Osteochondritis Dissecans of the Knee arthroscopy classification. Multivariable logistic regression analysis using stepwise model selection was used to determine factors associated with the likelihood of a mobile versus an immobile lesion. A 75% partition of the data was used for model training, and 25% was used as a validation cohort. Quantitative model fit statistics were computed using the holdout data, including sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC), along with the corresponding 95% CI. Results: A total of 407 patients in the prospective cohort met inclusion criteria, and 62% were male. The mean ± SD age was 13.7 ± 2.2 years, height 161.8 ± 5.3 cm, and weight 59.2 ± 42.2 kg. Arthroscopic evaluation yielded 235 immobile and 172 mobile lesions. Multivariable analysis determined that the best model to predict lesion mobility included chronologic age ≥14 years (P <.001), effusion on physical examination (P <.001), and any loss of range of motion on physical examination (P =.07), while controlling for male sex (P =.38) and weight >54.4 kg (P =.12). In the 25% holdout validation sample (n = 102), a sensitivity of 83%, a specificity of 82%, and an AUC of 0.89 (95% CI, 0.82-0.95) were achieved with these predictive factors. Conclusion: Age, effusion, and loss of motion can predict knee OCD lesion mobility at the time of arthroscopy. Education about lesion mobility can help with surgical planning and patient and family counseling. [ABSTRACT FROM AUTHOR]

Background: Treatment strategies for a symptomatic accessory navicular include both operative and nonoperative approaches. The primary aim of this study is to define health utility values for 7 health states experienced by those with a symptomatic accessory navicular who undergo operative and/or nonoperative treatment. Secondarily, the study incorporates the health utility values with treatment costs, probabilities of various outcomes, and duration of health states into a cost-effectiveness model comparing the nonoperative treatment protocol at our institution vs surgical excision. Methods: Institutional review board approval was obtained to call parents of patients 10-20 years old at the time of interview who were evaluated for a symptomatic accessory navicular from February 1, 2016, to March 2, 2023, at a single institution by one of 4 pediatric orthopaedic surgeons. Participants were asked to rate 7 health states from 0 to 100, with 0 representing death (if 18 years or older) or the worst health imaginable (if under 18 years) and 100 representing perfect health. Using published values for the probabilities of various treatment outcomes, time spent in various health states, and Medicare costs from the perspective of the payor and society, a decision analysis was constructed. Results: Health utility values for 7 health states were obtained. Operative treatment was preferred to nonoperative treatment in the base case model. Surgery was more expensive ($16 825) than nonoperative treatment ($7486). Using a willingness-to-pay threshold of <$50 000 per quality-adjusted life year (QALY), surgery was cost-effective compared to nonoperative treatment with an incremental cost-effectiveness ratio of $20 303/QALY. Sensitivity analysis revealed that the only variable that indicated a preference for nonoperative treatment is a 71% likelihood of nonoperative treatment resolving the condition. Conclusion: Unless a physician suspects at least a 71% chance of a symptomatic accessory navicular resolving without operative treatment, surgical excision is recommended from a cost-effectiveness perspective.

Background: The posterior tibial slope (PTS) has been proposed to be a radiographic risk factor for anterior cruciate ligament (ACL) injury in adults. However, this has not been well established in pediatric patients. Purpose: This systematic review and meta-analysis was performed to investigate any association between PTS and ACL tears in the pediatric population. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: A systematic review was performed to identify studies that examined the relationship between PTS, medial tibial slope (MTS), and lateral tibial slope (LTS) and ACL tears in children and adolescents aged ≤18 years. Full-text observational studies comparing PTS, MTS, and/or LTS values between pediatric (≤18 years of age) patients with and without ACL injury were included in this analysis. Review articles and case series were excluded. The authors calculated the mean difference (MD) via a restricted maximum-likelihood estimator for tau square and a Hartung-Knapp adjustment for random-effects model. Results: A total of 348 articles were identified in the initial database search, yielding 10 for final inclusion and analysis. There was no statistically significant association between PTS (MD, 1.13°; 95% CI, –0.55° to 2.80°; P =.10), MTS (MD, 0.36°; 95% CI, –0.37° to 1.10°; P =.27), or LTS (MD, 1.41°; 95% CI, –0.20° to 3.02°; P =.075) and risk for ACL injury in this population. Conclusion: The current study found that unlike what has been shown in adult populations, increased PTS may not be a significant risk factor for ACL tears in pediatric and adolescent patents. LTS was the only measured parameter that neared statistical significance, perhaps suggesting a potential role for this measurement in determining ACL risk if further research is done in this population.
