If you are looking for the answer of what assists all of those movements at the same time, the answer would be the Gluteus Medius and Minimus muscles. Think of a squat, while you are squatting both your hip and knee are flexed (the gluteus medius and minimus are the stabilizers/assisters during a squat), and while the hip is flexed the gluteus medius can internally rotate the thigh.
Flexion, abduction, and lateral rotation at the hip, and flexion and medial rotation at the knee.
Flexion, extension, rotation, adduction of the hip, extension and rotation at the knee
Flexion, extension, rotation, adduction of the hip, extension and rotation at the knee
The knee has 2 degrees of freedom. Flexion/Extension and varus/valgus rotation.
Tension in the posterior cruciate ligament when maintaining flexing a knee creates a lateral rotation in the tibia. This feature plays an essential role in locking the hip for stabilization.
knee flexion and hip extension.Biceps femoris also: knee external rotation and hip external rotation.Semi tendinosus and Semi membranosus also: knee internal rotation and hip internal rotation.hamstrings eccentric contraction causes knee extension and hip flexion, whilst the antagonist muscles are passive.
The principal movements occurring at this joint are flexion and extension of the leg, but some rotation also occurs in the flexed position.Flexion and extension of the knee joint are very free movements.
the hamstring is used for flexing the knee
In addition to simple flexion (bending) and extension (straightening) movements, the knee joint is designed to allow for rotation, gliding, and rolling movements.
It is called the Sartorius muscle located in the thigh. Here is the long definition. Assists in flexing, abduction and later rotation of the hip and flexing of the knee.
