Are cryo cuff knee systems worth it?

The knee is one of the most important joints in the body, but this also makes them prone to injuries. Knee injuries and knee pain results from various sporting activities, hereditary issues (arthritis, etc.) or getting older, and can be a nightmarish experience. Cold therapy is a simple and cost-effective way of managing injuries and pain in the knee area. When used correctly, cold therapy can provide relief from pain, reduce swelling, and promote the healing process. There are different ways of delivering cold therapy to your knees, including ice packs/wraps, ice gels, ice cups, instant ice packs, frozen vegetables, and cryo cuffs. Among athletes, the cryo cuff knee system is a popular method for administering cold therapy.

What is Cold Therapy?

 
Cold therapy (also called cryotherapy or ice therapy) is a type of treatment which involves the application of ice to an injured or painful part of the body, to reduce pain and swelling, stop bleeding, and improve the process of healing. Ice therapy is not a treatment per se, but an ameliorative measure that makes it easier to bear the discomfort of an injury by numbing the skin to create a momentary sense of relief.
 
In the case of knee injuries, ice therapy is helpful as it can be used to reduce the pain until the injury generating the discomfort completely heals. However, cold therapy must be used correctly and at the right time for it to produce desirable results.
 
 

When to Use Cold Therapy for Knee Pain

 
Cold therapy is used to control pain in recent injuries, for example, when you bruise your knee, tear a ligament or something similar. If your knee injury causes inflammation, cryotherapy is one of the best methods for reducing the inflammation. It can also be used to control chronic knee pain resulting from conditions such as arthritis, rheumatoid arthritis as well as tissue fatigue injuries.
 
A doctor may ask you to invest in some form of cold therapy device prior to upcoming knee surgery because immediately after the operation you will most likely experience pain and swelling which can be relieved by cold compression therapy. They are also recommended for patients going through physiotherapy for other (non-surgical) knee-related issues because intense physiotherapy sessions can sometimes leave you feeling as if you had just undergone surgery. The main purpose of this system is to provide compression and ice therapy, which will relieve some of the pain and swelling.
 
 

What is a Cryo Cuff Knee System And Can it Help?

 
A cryo cuff knee system (also known as a knee ice machine or passive cold compression therapy unit), is a form of cold compress which is wrapped around the painful or swollen body part and consists of three basic components:

  • The cooler – which you fill with ice and water
  • The cuff – a sack which you wrap around your knee
  • The tube – provides the water flow between the cooler and the cuff

 
The cooler is filled with water and then connected to the cuff. The cuff is wrapped around the knee to apply cold fluid to the knee. The cold compression helps to reduce pain, swelling, and muscle spasms as well as aid the healing process. It is popular among athletes and used after injury, physical therapy sessions, and surgery. One of the reasons why athletes prefer the cryo cuff system is that it delivers the cold for longer, making it more effective in reducing pain and inflammation.
 
This article will focus on the Aircast Cryo Cuff Knee System because it is one of the most popular brands out there, which makes it easier to find replacement parts and information on them.
 
 

Types of AirCast Cryo Cuff Knee Systems

 
There are three main types:
 
1. The gravity-based system. This is the lower cost version where water flows through the cuff by raising and lowering the cooler. Movement of the cooler also affects the compression of the cuff. The higher you raise the cuff, the more pressure (compression) you will feel.
 

 
 

2. Aircast Self Contained Cryo Knee Cuff – This version is more portable because there is no need for a cooler. Simply fill the cuff with cold water and ice and you can take it anywhere you go. It’s also designed with a “pressure bulb” which allows you to control the amount of compression.
 

 
 

3. The IC pump system (or “AutoChill” system). This system is a little bit more expensive than the gravity system because it comes with a small electric pump which provides automatic continuous cold water flow and also provides intermittent pulsating pressure. Some say that these two additional features allow for less swelling and faster recovery times.
 

 
 
 

Sizing

 
To determine what size you need, measure the circumference of your thigh approx. 6 inches above the center of the knee cap, then refer to the following:

  • Small – 10 to 19 inches (or 25 to 48 centimeters)
  • Medium – 18 to 23 inches (46 to 58 centimeters)
  • Large – 20 to 31 inches (51 to 79 centimeters)

 
 

How To Use An AirCast Cryo Cuff Knee System

The system is simple to use. Here are step-by-step instructions on how to set it up and use it:

1. Start by getting the cooler ready.

  • Attach the blue tube to the cooler.
  • Fill the cooler with cold water up to the indication line.
  • Add ice.
  • Place the insulation disk on top of the water/ice.
  • Place the lid on top and secure it. Make sure it’s tight to ensure no water leakage.
  • Wait five to ten minutes to make sure the water is cold enough.

 
2. Wrap the cuff around the affected knee. (Make sure the cuff is empty beforehand.). The top strap should be snug while the bottom strap should be a bit loser. Then adjust the front strap.

3. Connect the other end of the blue tube to the cuff and open the cooler air vent.

4. Raise the cooler 15 to 20 inches above the cuff and leave it there until the cuff is filled with water, then close the cooler air vent.

5. Place the cooler at the same level as the cuff, preferably on a stable surface (desk, coffee table, etc.)

6. If you have the motorized version, at this point you will plug it in and it will automatically start circulating the cold water.

7. Sit there and enjoy the ride.
 


 

Other tips

  • With the regular (non-motorized) version of the cryo cuff, your body heat will eventually warm up the water before you are done using it. If this happens, just lower the cooler below the cuff to remove the warm water, and then repeat steps 4 and 5 above.
  • If you find that there is too much pressure, or you feel tingling or numbness, lower the cooler a little bit at a time until the cuff feels more comfortable.
  • If you have a bandage or dressing of some sort around your knee, make sure it isn’t too tight before securing the cuff to your knee.

 
Important – This is an overview on how to use it. You should always refer to the owner’s manual for specific instructions. When using cold therapy, it is important not to overdo it. If you notice the skin is going numb, stop applying the ice to avoid damaging the nerves and burning the skin in the area. Also, for effectiveness, cold therapy should be done as frequently as possible.
 
 

Are Cryo-Cuff Knee Systems Worth It?

 
Some people will say that using ice packs (or even a frozen bag of peas) is all you need to reduce the swelling and pain. In some circumstances, they are right and simple cold therapy may be enough. However other situations may require more that just simple icing (i.e.: cryo cuff knee systems are often recommended for post knee surgery recovery, moderate to severe knee pain, etc.). The added benefit of compression may be required depending on your situation. To determine what you need, it is crucial that you consult a doctor. If you find that the Aircast doesn’t fall within your budget, another popular option (and more affordable) is the following:

7 thoughts on “Why You Need a Cryo Cuff Knee System

  1. Awesome article. I bought a Cryo-Cuff when I had an ACL replacement and it was the best investment. I had to ice my knee mutliple times a day for long periods and this system made it so much more convenient then ice packs. I highly recommend anyone who has knee issues and are relying on cold therapy to get one of these…you won’t regret it!

    1. Thanks for leaving the comment Roberta. I’m glad you liked the article. I’m sorry to hear that you had to go through an ACL replacement but it’s good to know that you were able to get some relief with the Cryo-Cuff afterwards. Cheers.

  2. Awesome information. We sell some of these products but the information provided and excellent. I would to recommend my clients over to your blog to read some interesting articles you provide.

    1. Well, it depends on how long you plan on using it. If you are just using it a few times to recover from a minor injury, stick with the regular one. But, if it’s something major like ACL surgery and your doctor wants you to use it for several weeks during the recovery process, then I would go with the motorized one if you can afford it. The flow is more evenly spread out and you can just sit there, relax and let it do its thing. The regular one works well, except that after a couple of weeks of using it, you may get extremely annoyed with the up and down motion. I hope this helps.

    1. Hi Dave – Yes, it’s great for reducing swelling after an injury and surgery. Their kit also comes with an extra ice gel pack, which comes in handy if you need extra icing time. Great bang for your buck.
