What are the degrees of knee flexion?

• Flexion: 0 degrees to 100 degrees
• Backward extension: 0 degrees to 30 degrees
• Abduction: 0 degrees to 40 degrees
• Adduction: 20 degrees to 0 degrees
• Lateral rotation: (rotation away from the center of the body) 0 degrees to 60 degrees
• Medial rotation: (rotation towards the center of the body) 0 degrees to 40 degrees

What is the normal range of motion of the knee?

What is the range of motion for knee flexion?

Simply put, it is the inability to straighten the knee fully and is also commonly called as flexion contractual. The standard motion range (AROM) of a knee is 0° extension and 140° flexion. In the case of deformities, then the normal active range of motion is reduced.

What are the degrees of knee extension?

• 5 - 85 degrees (80 degree arc of motion with 5 degree extension deficit)
• 0 -85 degrees (85 degree arc of motion with normal extension)
• 5 - 0 - 85 degrees (5 degrees of hyper extension through 85 degrees of flexion)

Is there an app to measure knee flexion?

The orthophysical app provides a means of measuring and monitoring knee range of motion.

What is normal flexion of knee?

A fully bent knee will max out at about a full range of motion of 135° degrees of flexion. As a general rule, a knee flexion of about 125° will allow you to carry out most normal activities. For daily living, a minimum flexion of around 105°-110° is required.

How do you use the goniometer on Iphone app?

The "Goniometer" app measures the angle of the device, using the accelerometer and gyroscope. Just place your device against two surfaces in turn and Goniometer will give you the angle between them.

How do you measure knee flexion after TKR?

ROM is measured using an instrument called a “goniometer”. For instance, a completely straight knee joint measure 0° while a fully bent knee clocks in at about 135° degrees of flexion.

How many degrees should my knee bend after knee replacement?

Knee Replacements: What you need to know The goal after knee replacement is to get the knee to at least 120 degrees of flexion or bending motion. You need at least 110 degrees to enter and exit a car and most people need 110 to 120 degrees to ride a bike.

What is normal knee flexion after knee replacement?

Most of our patients end up with 120 to 125 degrees of flexion. Make sure that you know how much flexibility you have in your knee. Make sure you ask your therapist specifically how much bend your knee has at each visit.

How do you document a knee range of motion?

Documenting Knee Range of MotionIf a person has 10 degrees of knee hyperextension and 130 degrees of knee flexion, it would be documented as 10-0-130.If a person has a 10 degree contracture and loss of full knee extension with 130 degrees of knee flexion, it would be documented as 0-10-130.

How to measure knee flexion?

1 – Using a camera phone to take photos of your knee flexion and extension. 2 – Having a family member or friend use a goniometer. 3 – Using a flexible tape measure to measure progress not degrees.

What is knee flexion after knee replacement?

When your knee is bent, fully flexed, this is called knee flexion. Normal knee flexion after a total knee replacement may range between 120-degrees and 135-degrees. Some implants may provide for greater range of motion.

How to measure progress?

Simple ways to measure progress based on functional include: 1 How long are you able to stand on your feet? 2 Are you able to stand from the commode without using your hands? 3 Are you able to walk up stairs with a step over step gait pattern? 4 Are you able to stand from your couch without pushing yourself up? 5 After long in minutes or far in distances are you able to walk without an assistive device?

How to measure knee range of motion?

The best way to measure knee range of motion is to: Lie down on your back with your leg straight, on a flat, preferably hard surface. Place the axis of the goniometer over the lateral femoral epicondyle. Line the stationary arm of the goniometer up with the greater trochanter along the outer thigh. Line the other arm of the goniometer up with ...

What is a normal ROM for a knee?

Normal passive knee ROM is: Passive Knee Flexion: up to 150 o, depending on the size of the leg – the limit is the calf pushing onto the back of the thigh. Passive Knee Extension: up to 10 o hyperextension is considered normal.

What is a goniometer?

A goniometer is essentially a specially designed protractor that measures joint angles. There is a circle in the middle of a goniometer representing 360 o of motion, out of which come two extending arms: a stationary arm (connected to the protractor) and a moveable arm.

What is passive knee ROM?

Passive Knee ROM: How far the knee can bend and straighten when moved by an external force, usually another person – the leg and knee muscles completely relaxed.

Where is the lump on the ankle?

Ankle: Lateral Malleolus – the bony lump on the outer side of the an kle. Hip: Greater Trochanter – a bony lump just below the hip joint on the outer side of the thigh. Ideally, you will need someone to do the measuring for you – it is hard to get an accurate measurement if you try and do it yourself.

How much range of motion is needed for walking?

At the knee joint, most functional activities require up to 120 degrees of knee flexion, rather than the full 135 degrees, however, virtually all functional activities require full knee extension.

Can you measure ROM without a goniometer?

How To Measure Knee ROM Without A Goniometer. If you don’t have a goniometer, you can still assess your ROM. This can be really helpful for seeing what progress you are making with your rehab after a knee injury. It won’t be as accurate as using a goniometer, but it does give you somewhere to start.
