Knee replacement can often 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 the pain (especially at the night, when the patient is sleeping) is a 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.


The most commonly used phrase after knee replacement surgery and when recuperating from it is “RICE” – which stands for rest, ice, compression, and elevation. Most TKR surgeries will end with advice to follow the RICE principle to avoid further inflammation to the knees and to ensure that the injury gets healed.

Out of the four key elements of recuperating from a TKR – Elevation 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, the elevation is very important in TKR. The video below shows what to expect after total knee replacement surgery.

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

There are several factors to consider when choosing the best knee pillow for use after TKR. We have listed below some of the parameters.


Most of the pillows for post knee replacement surgery are wedge-shaped (like a triangle) which hold 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, 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 may have different types of covers – nylon, polyester, bamboo etc. Look for the most comfortable cover type – one which does not make you sweat too much, and neither is it too uncomfortable.


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 pillow that has a steeper slope and is lightweight will move a lot, and may not be a good choice. For restless sleepers, it is recommended to use a heavier pillow which 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 will help prevent the accumulation of sweat and make you feel a lot more comfortable, especially if you feel hotter at night.


Typically a mattress with memory foam may be less firm than that which is made from high-density foam. That said, firmness is a personal choice that can depend upon several factors.

Other factors:

Most wedge pillow retailers and offer trials, which means that you can test the 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, since it varies by brand, model, and retailer.  Most warranties cover defects for less than 3 years. However, be sure not to buy one that has zero warranty coverage.

In the next section, we will discuss our top picks for knee pillows post knee replacement surgery.
