After lower extremity surgery, your orthopedic doctor may limit the amount of weight you can place on your operated leg. This restriction is necessary to provide adequate time for proper bone healing. It also allows for any hardware that was placed during the surgical procedure to remain in the proper position. Understanding weight-bearing restrictions is often confusing. Below you will learn the different types of weight-bearing restrictions as well as how to perform them.

Why is it important to closely adhere to your weight-bearing restrictions? Because if you do not, you can distrust healing and delay your recovery. Your weight-bearing restrictions are meant to protect your body as it is healing.

It is a good idea to check in with your doctor or physical therapist to understand your specific weight-bearing restrictions and how to maintain them properly.

Non-Weight Bearing

Non-weight bearing means that NO weight can be placed on the operated leg. This is the most restrictive of all weight-bearing limitations. Since you are not able to bear any weight on the leg, an assistive device, such as a walker or crutches, will be necessary for you to walk.

When walking with your walker or crutches, keep your affected knee bent up and keep your toes off the floor. No weight means no weight - even the slightest bit of pressure through your leg can cause problems.

Toe Touch Weight Bearing

Toe touch weight bearing means that only the toes on your operated leg are able to contact the ground.

This is for balance only, however, and thus no significant amount of weight should be placed through your toes. As a result, an assistive device such as a walker or crutches will again be necessary for you to walk.

Partial Weight Bearing

Partial weight bearing allows you to place half of your weight on the operated extremity.

Begin by using a scale to see how much pressure is on your affected leg when half of your weight is placed on it. Use your assistive device to stand with slight pressure on your leg.

Your PT can help you with progressive partial weight bearing. Sometimes your doctor may give specifics when prescribing partial weight bearing. He or she may prescribe 25% weight bearing, 50% weight bearing, or 75% weight bearing.

Make a mental note of this, and limit the pressure placed on your operated leg during walking to this restriction. As full weight bearing is still not allowed, crutches, a cane, or walker can help you walk without losing your balance.

Full Weight Bearing

Full weight bearing allows you to place all of your weight on the operated extremity. There are no restrictions in regards to the amount of weight placed on the leg, therefore assistive devices are usually not necessary.

If you have been walking with a cane or crutches, you may not want to simply throw those things away, as you may need them to progress from partial to full weight bearing.

Sometimes progressing from partial to full weight bearing can make your muscles a little sore, so expect this. Your PT can help you safely progress from partial to full weight bearing.

After injury or surgery, your doctor may limit your weight bearing as things are healing. Take a moment to learn about different weight-bearing restrictions, and work closely with your physical therapist to properly progress your weight-bearing status as directed by your doctor.
