Case of a 14-year-old male patient with idiopathic limb length discrepancy. a Preoperative X-ray, demonstrating pelvic obliquity and shortening of the right leg of 3.9 cm. b Postoperative X-ray after the patient was treated with tension band plates on both medial and lateral epiphyses of the distal femur and proximal tibia. c At 1-year follow-up, partial metal removal had to be performed due to the progression of varus malalignment. Tension band plates of the medial distal femur and medial proximal tibia were removed. d At 2.5-year follow-up, varus malalignment was improved to 6° with a residual LLD of 1.4 cm
