Tibial Tuberosity Avulsion - Bilateral A Case Report

Abstract

Bilateral avulsion fractures of tibial tuberosity are very rare injuries. It is seen in adolescent males and corresponds to maturation of extensor mechanism and growth plate closure.
13 years old male presented with hyperflexion injury while playing football. Imaging showed bilateral tibial tubercle avulsions with patellar tendon and medial patellofemoral ligament tear. He was treated with open reduction and internal fixation with 3.5mm screw and K-wire and augmentation with suture anchor was done on both sides.
Avulsion fractures of the tibial tuberosity can be associated with collateral ligament injuries, anterior cruciate ligament tears and meniscal tears. The objectives of treatment are to restore the extensor mechanism and congruency of the tibial articular surface and to address any associated soft tissue injuries.
Conclusion
Bilateral simultaneous avulsion fractures of the tibial tubercle usually occur in a muscular adolescent athletic male. Xray is diagnostic, but MRI should be done to rule out any associated injuries and to guide the treatment plan. These fractures usually require open reduction and internal fixation, and the complication rates are very low.
