Correction of Lateral Tibial Plateau Malunion.

The results of open reduction and internal fixation for tibial plateau fractures are generally favorable when articular morphology and stability are restored. When these goals of treatment are not achieved, limited function often results. The patient presented in this video complained of pain and an inability to resume his previous work. Evaluation suggested that root causes of these difficulties included widening of the plateau, significant depression of the articular surface, resultant valgus instability, and a displaced nonfunctioning lateral meniscus. This video demonstrates the planning and correction of a long-standing intraarticular malunion of a lateral tibial plateau fracture.
