Outcomes of pediatric anterior cruciate ligament reconstructions in patients with and without bucket handle meniscus repairs

The purpose of this study was to report the outcomes of concomitant bucket handle meniscal tear (BHMT) repair and anterior cruciate ligament (ACL) reconstruction and to compare the outcomes with those after isolated ACL reconstruction in patients aged ≤16 years. Patients in our database from 2013 to 2017 were retrospectively analyzed. Patients were assigned to one of two treatment groups based on the presence of BHMTs: no meniscal tear group (group A) and BHMT group (group B). All BHMTs were repaired using the combined inside-out with all-inside technique. This study included 64 knees divided into two groups: 47 knees in group A and 17 knees in group B. There was a significant difference in the interval between ACL injury and surgery between groups A and B (69 vs. 150 days, respectively; P0.001). Mean postoperative International Knee Documentation Committee and Lysholm scores in group A were slightly, although significantly, improved compared to those in group B (96.5 vs. 92.6, respectively; P0.05, and 98 vs. 95, respectively; P0.05). There were no significant differences in postoperative anteroposterior laxity and graft failure rate between the groups. In group B, four patients (23.5%) required surgery for incomplete meniscal healing. Postoperative International Knee Documentation Committee and Lysholm scores of patients with BHMTs were significantly lower than those of patients without any meniscal tear, although with significant improvement in the amount of instability. Level of evidence was Level III.
