Delaminated Patellar Tendon Rupture in a Pediatric Patient: A Case Report

Case:
We present a 12-year-old boy with partial delamination of the patellar tendon in the coronal plane and bipolar avulsion fracture of the tibial tubercle and patella after a planting injury while skateboarding. Pediatric patellar tendon rupture with associated bipolar avulsion fractures is rare. Furthermore, to the best of our knowledge, a delamination injury pattern of the patellar tendon has not been described.
Conclusion:
This type of extensor mechanism injury has not been reported in the literature. Repair with Krackow sutures and suture-bone tunnel technique, with consideration of the proximal tibial physis, is a safe and effective way to fix this unique pathology.
