Anterior tibial slope deformity secondary to malunion of tibial plateau fractures is an uncommon sequela that may result in significant biomechanical alterations. We report the case of a 19-year-old patient presenting with a severe sagittal deformity following previous osteosynthesis, with a tibial slope of 117.8° measured on computed tomography, corresponding to 27.8° of anterior slope relative to the neutral value (90°).
A posterior closing-wedge osteotomy was performed based on three-dimensional preoperative planning, with a planned wedge resection of 28°. Postoperative measurement demonstrated restoration to 90°, achieving complete neutralization of the deformity.
At 6-month follow-up, the patient demonstrated full range of motion (0-135°), return to work, and low-impact physical activity without pain or subjective instability.
This case suggests that, with appropriate patient selection and precise preoperative planning, posterior closure osteotomy with 3D planning can be a valid and reproducible option for the correction of severe reverse tibial slope secondary to malunion.
