________ of the Knee is Preceded by Unlocking of the Knee

Question

________ of the knee is preceded by unlocking of the knee.
A) Extension
B) Protraction
C) Opposition
D) Retraction
E) Flexion

Accepted Answer

Flexion of the knee is the bending of the knee joint, which is preceded by the unlocking of the knee joint. This unlocking mechanism is known as the "screw-home mechanism," where the femoral condyles rotate on the fixed tibial plateau, allowing the knee to unlock and then flex.
