What is the most common autogenous material used to replace the condyle?

  1. Iliac crest

  2. Costochondral bone

  3. Femur

  4. Sternum

The correct answer is: Costochondral bone

Costochondral bone is the most common autogenous material used to replace the condyle. This is because the costochondral graft has the best chance of maintaining the morphology of the joint due to its cartilaginous head. The other options, such as the iliac crest, femur, and sternum, are less ideal for condyle replacement due to their differences in structure and function compared to the natural condyle.
