Knee replacement can be a painful and trying procedure. Depending on how well the procedure goes and how well cared for the knee is post-surgery, the patient may take anywhere between 4 to 6 weeks to fully recover from the procedure.

One of the things that can reduce the intensity of pain at nighttime when the patient is sleeping is an orthopedic knee pillow.

Knee pillows come in several varieties; however, for people who are recovering from total knee replacement (TKR) surgery, wedge-shaped knee pillows are the most common variety.

In this article, we review some of the best knee pillows after knee replacement for the elderly. The table below provides a quick snapshot of our top picks, and you can scroll down for detailed reviews and discussions.

The RICE Recovery Method

The most commonly used phrase after knee replacement surgery and when recuperating from it is the “RICE” method, which stands for rest, ice, compression, and elevation. Most total knee replacement (TKR) surgeries will end with advice to follow the RICE principle, as it can help to avoid further inflammation in the knees and ensure that the injury heals quicker.

During the recovery period from your surgery, ice packs and an elevation pillow can be of help.

The leg elevation aspect of RICE is taken care of by the knee pillow, which we will be discussing further in this article.

Elevating the leg at 35 degrees from the hip is a safe and effective way to reduce total blood loss1 by 25%. Therefore, leg elevation is very important after TKR.

The video below shows what one should expect after having knee replacement surgery.

How to choose the best knee pillow after a knee replacement surgery

There are several factors to consider when choosing an orthopedic knee pillow for use after TKR. Listed below are some of the parameters.


Most of the pillows for post knee replacement surgery are wedge-shaped (like a triangle), which holds the knee and leg at an incline to the rest of the body.


Knee pillows can come in a variety of lengths, widths, and heights. Ideally, they should be able to cushion your knees based upon the size of your foot. 


The large, thick portion at the end of the incline should measure at least 7 inches, and in some cases, it can go up to even 12 inches. The comfort zone between a slow incline and a high incline really depends on personal choice.

Most knee pillows are made with memory foam. The pillow cover may be composed of nylon, polyester, bamboo, or another fabric material. Look for a cover type that is most comfortable for you – one which does not make you sweat too much and is comfortable for your skin. 


The pillow should ideally have a machine washable cover so that it can be easily washed at regular intervals.


Wedge pillows can cost a lot of money, but there are cheaper options available as well. Price is often related to the quality of the materials and durability.


If you tend to move throughout the night, a leg wedge pillow that has a steeper slope and is lightweight can shift around, disrupting its optimum functional position. For restless sleepers, it is recommended to use a heavier leg wedge pillow that will hold in place and give you comfort throughout the night.


Pillows that have an outer cover made of breathable materials like nylon, bamboo, and polyester can help prevent the accumulation of sweat and make you feel a more comfortable, especially if you tend to have night sweats or just feel hotter during sleep.

Typically, a mattress with memory foam may be less firm than that which is made from high-density foam. That said, firmness of a knee pillow is not as critical a decision as with a mattress, and can be a matter of personal preference here.

Other factors

Most knee wedge pillow retailers offer trials, which means that you can test the knee wedge pillow for 30 to 90 nights and return it if it doesn’t suit you. Shipping and return policies are also important, especially the cost of shipping back. Of course, warranty coverage is also an important factor and can vary by brand, model, and retailer.  Most warranties cover defects within 3 years. Be sure not to buy one that lacks warranty coverage.
