Musculoskeletal: Lower Extremity: Tibiofemoral Joint: Osteokinematics and Arthrokinematics

Question 1

Tibiofemoral Joint

Osteokinematics: Flexion

Answer 1

• Arthrokinematics of the knee joint during flexion in the open kinetic chain.
• In the open kinetic chain the concave surface of the Tibia will Roll and glide POSTERIORLY on the convex surface of the femur.
• Arthrokinematics of the knee joint during flexion in the closed kinetic chain.
• In the closed kinetic chain the convex surface of the femur will roll POSTERIORLY and glide ANTERIORLY on the concave surface of the tibia.

Question 2

Tibiofemoral Joint

Osteokinematics: Extension

Answer 2

• Arthrokinematics of the knee joint during extension in the open kinetic chain.
• In the open kinetic chain the concave surface of the Tibia will Roll and glide ANTERIORLY on the convex surface of the femur.
• Arthrokinematics of the knee joint during flexion in the closed kinetic chain.
• In the closed kinetic chain the convex surface of the femur will roll ANTERIORLY and glide POSTERIORLY on the concave surface of the tibia.
