Restoring the joint surface in tibial plateau fractures aims to reduce which long-term complication?

• A. Post-traumatic arthritis
• B. Compartment syndrome
• C. Avascular necrosis of femoral head
• D. Osteomyelitis

Answer: (A)

Restoring the joint surface in tibial plateau fractures aims to maintain a smooth, congruent articular surface so the knee can bear load evenly. When the articular surface is deformed or has a step-off, the cartilage experiences abnormal contact pressures, leading to accelerated wear and degeneration over time. By anatomically reducing the surface and preserving alignment, you minimize focal stress, slow cartilage damage, and reduce the risk of developing post-traumatic arthritis in the long term. Other issues like compartment syndrome are acute problems related to swelling after injury, avascular necrosis of the femoral head concerns the hip, and osteomyelitis is an infection risk. They are not the long-term consequence this restoration specifically targets.
