[Intra-articular proximal tibia fractures]

The incidence of proximal intra-articular tibial fractures is continuously increasing. In addition to high-energy trauma in young patients, osteoporotic fractures occur more frequently in geriatric patients. After a thorough clinical examination including X‑ray and computed tomography (CT) imaging, consolidation of the soft tissue is followed by surgical treatment to achieve the best possible anatomic reconstruction of the articular surface. Nonanatomic reduction with articular gaps >2.5 mm leads to a significantly increased risk of osteoarthritis. Selection of the surgical approach and planning of the osteosynthesis are based on the fracture morphology and the existing soft tissue damage. In addition to arthroscopically assisted percutaneous procedures, sophisticated osteosynthesis is often necessary, which requires several surgical approaches. In this context, posterior surgical approaches are becoming increasingly more important. Primary knee arthroplasty can also play a role, particularly in older patients.
