What is another name for the stifle joint in a chicken patient?

• A. Femoral-tibiotarsal joint
• B. Tarsocrural joint
• C. Hip joint
• D. Humeroradial joint

Answer: (A)

In birds, the stifle is the knee region, located where the femur meets the tibiotarsus. The tibiotarsus is the main leg bone formed by the fusion of the tibia with some tarsal bones, so the joint between the femur and this bone is called the femoral-tibiotarsal joint. This naming directly reflects the bones involved, which is why it’s the correct term for the avian stifle. The hip joint is between the pelvis and femur, the tarsocrural joint is the ankle, and the humeroradial joint is in the wing, so they do not describe the stifle.
