Triplane Knee Fracture: A Rare Case Report

Triplane fractures of the knee are uncommon, accounting for approximately 2%–4% of all physeal injuries. These complex fractures involve multiple planes and are typically observed in adolescents nearing skeletal maturity. This case involves a 16-year-old male who sustained a triplane fracture of the proximal tibia in his left knee. He was treated with closed reduction and percutaneous epiphysiodesis. Accurate diagnosis of triplane fractures necessitates computed tomography scans for assessing the extent of the injury and planning appropriate management. Timely and precise treatment is crucial to minimize potential complications such as growth disturbances, angular deformities, or joint incongruity.
