medial tibial plateau fracture
Break in the medial aspect of the proximal tibia involving the weight-bearing surface of the knee joint, often requiring surgical intervention.
Full Definition
Medial tibial plateau fractures involve the medial condyle of the proximal tibia and represent a subset of tibial plateau fractures that typically require surgical management due to their involvement of the primary weight-bearing surface of the knee. These injuries commonly occur from high-energy trauma in younger athletes or low-energy falls in older athletes with osteoporotic bone. The medial plateau bears approximately 70% of the axial load across the knee, making anatomical reduction crucial for optimal outcomes. Associated injuries may include meniscal tears, ligamentous disruption, and compartment syndrome. Clinical presentation includes knee pain, swelling, hemarthrosis, and inability to bear weight. CT scanning is essential for surgical planning to assess fracture pattern, depression, and comminution. Treatment typically involves open reduction and internal fixation to restore joint congruity and stability.
Usage
Usage note: Specify medial vs. lateral to distinguish injury pattern and treatment approach.
