“…As a result of another study that evaluated ACL injuries in children, there is a significant association between an ACL tear and the increased patellar tendon length with a greater Insall-Salvati ratio. For this reason, patella alta can be a risk factor for ACL injuries in pediatric patients [14]. Mean preoperative value of the Insall-Salvati ratio is 0.91 ± 0.1 according to our study.…”

Introduction/Objective The relationship between anterior knee pain and the Insall-Salvati ratio after anterior cruciate ligament (ACL) reconstruction with hamstring tendon were evaluated in this study. Methods We evaluated 39 patients that had an ACL reconstruction surgery with hamstring tendon. All the patients were evaluated for the Insall-Salvati ratio preoperatively and postoperatively. Fourteen patients had anterior knee pain at the end of the first year after the surgery. The patients were evaluated at the end of the first year after the surgery with the Lysholm score and the Tegner activity scale. The patients' preoperative and postoperative measurements were analyzed by using the Wilcoxon test, and the differences between the patients with anterior knee pain and those without it were analyzed by the Mann-Whitney U test. Results Preoperatively, mean Insall-Salvati ratio was found to be 0.91 ± 0.1, whereas postoperative ratio was 0.85 ± 0.09 (p ≤ 0.05). In the group without anterior knee pain, the mean Tegner activity score was 8.56 ± 1.04, and the mean Lysholm score was 87.36 ± 9.42. The mean Tegner activity score was 7.21 ± 0.97 and the mean Lysholm score was 74.43 ± 9.94 in the group with anterior pain. There was a decrease in the Insall-Salvati ratio as a result of the surgery, but patients with anterior knee pain had lower values of the Insall-Salvati ratio preoperatively. Conclusion Low preoperative Insall-Salvati ratio can be an indicator of anterior knee pain in the early period after ACL reconstruction with hamstring tendons. The mean Tegner activity score and the mean Lysholm score have higher values in the group without anterior pain postoperatively.

The management of pediatric patients with an anterior cruciate ligament (ACL) tear can be a challenging endeavor for physicians, athletic trainers, coaches, and parents alike. In particular, the significant longitudinal growth that arises from the physes about the knee creates a unique set of circumstances that must be considered in this patient population. The purpose of this review is to provide a summary of the most recent current literature for the management of skeletally immature patients with an ACL tear.

Background: Reports of anterior cruciate ligament (ACL) injury in patients with skeletal immaturity have been increasing. Variations in knee joint anatomy have been linked to ACL injury risk factors. Purpose: To identify associations between ACL injury, patella alta, and femoral trochlear dysplasia in patients with skeletal immaturity by using magnetic resonance imaging (MRI). Study Design: Cross-sectional study; Level of evidence, 3. Methods: This retrospective study included 231 patients with skeletal immaturity—116 with acute complete noncontact ACL injury and 115 without ACL injury (controls)—who underwent knee MRI. Cases of femoral trochlear dysplasia were divided into 4 types according to the Dejour classification scheme. Patellar height and patellar tendon length were measured via sagittal MRI, and the Insall-Salvati ratio (ISR) was calculated. Results: In the ACL injury group, 56 (48.3%) knees exhibited trochlear dysplasia, including 51 (91.1%) that were Dejour type A; and in the control group, 12 (10.4%) knees exhibited trochlear dysplasia, 12 (100%) Dejour type A. The prevalence of femoral trochlear dysplasia was significantly higher in the ACL injury group than in the control group ( P < .001). The ISR was not significantly different between the ACL injury and control groups (0.9 ± 0.2 vs 1 ± 0.2 mm; P = .16). The correlation between ISR >1.2 and presence of ACL injury was not significant. Conclusion: Femoral trochlear dysplasia was associated with ACL injury in patients with skeletal immaturity. In particular, Dejour type A femoral trochlear dysplasia was correlated with ACL injury patients with skeletal immaturity. Also, the possibility of ACL damage exists in patients with skeletal immaturity and femoral trochlear dysplasia.
