Which structure forms the top surface of the tibia that articulates with the femur?

• A. Tibial Plateau
• B. Tibial Tuberosity
• C. Distal Condyles
• D. Intercondylar Notch

Answer: (A)

The top surface of the tibia that articulates with the femur is the tibial plateau. This is the smooth, flat area at the proximal end of the tibia that forms the superior articular surface of the knee, with medial and lateral plateaus matching the femoral condyles to create the knee joint. The other features aren’t part of this articulation: the tibial tuberosity is the bump where the patellar ligament attaches, not a joint surface; the intercondylar notch is a notch on the femur between its condyles, not a surface of the tibia; and “distal condyles” don’t describe the top knee surface at all.
