Question

Using approximately 400-500 words, describe how and why maintaining the position of full knee extension limits the ability to maximally flex the hip both actively and passively. Does maintaining excessive hip flexion limit the ability to accomplish full knee extension? Consequently, describe how and why maintaining the position of full knee flexion limits the ability to maximally extend the hip both actively and passively. Does maintaining excessive hip extension limit the ability to accomplish full knee flexion?

Answer 1

The ability of a knee to straighten all the way is referred as knee extension.But when the surgery is done to knee the common problem seen in patients is lose of flexion and extension of knee.

Hamstring are the muscles and their groups of tendons which help in walking,running, and other physical activities. the function of hamstrings is to flex the knee joint and it also extends thigh to the backside of body.

Maintaining position of full knee flexion limits the ability to maximally extend the hip both actively and passively.

When the knee is held in extention the rectus femoris reach active insufficiency sooner in hip flexion than knee flexion.

when the knee is held in extention the hamstrings reach passive insufficiently.They would sooner reach hip flexion than they would reach flexion in knee.

2)Yes, maintaining excessive hip extension limit the ability to accomplish full knee flexion because of the rectus fumoris reaching active insufficiency.hamstrings reaching passive insufficiency​.
