What is it and do I need one?
A cryogenic cuff knee system (also known as a knee ice machine or passive cold compression therapy unit) consists of three basic components:
* The cooler – which you fill with ice and water
* The cuff: a sac that wraps around the knee
* The tube: provides the flow of water between the cooler and the sleeve
A doctor will usually ask you to purchase one of these units before your next knee surgery because immediately after the operation, you will most likely experience pain and swelling that can be relieved by cold compression therapy. They are also recommended for patients undergoing physical therapy for other (non-surgical) knee-related problems because intense physical therapy sessions can sometimes make you feel like you just had surgery. The main purpose of this system is to provide compression and ice therapy, which will relieve some of the pain and swelling.
This article will focus on the Aircast Cryo Cuff Knee System because it is one of the most popular brands out there, making it easy to find replacement parts and information about them.
Different Types of AirCast Cryo Cuff Knee Systems?
There are two main types:
* The gravity-based system – This is the lower cost version where the water flows through the sleeve when raising and lowering the cooler. Cooler movement also affects sleeve compression. The more you lift the cuff, the more pressure (compression) you will feel.
* The IC pump system (or “AutoChill” system) – This system is a little more expensive than the gravity system because it comes with a small electric pump that provides a continuous automatic flow of cold water and also provides intermittent pulsating pressure. Some say that these two added features allow for less swelling and faster recovery times.
Both systems are available in three adult sizes. To determine what size you need, measure the circumference of your thigh approx. 6 inches above the center of the patella, 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 do we 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 preparing the cooler.
has. Connect the blue tube to the cooler.
b. Fill the cooler with cold water up to the indication line.
against Add ice.
d. Place the insulating disc on top of the water/ice.
me. Put the lid on top and secure it. Make sure it is tight to ensure no water leaks.
F. 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 loose. Then adjust the front strap.
3. Connect the other end of the blue tube to the hose and open the air outlet of the cooler.
4. Raise the cooler 15-20 inches above the hose and leave it there until the hose fills with water, then close the cooler air outlet.
5. Place the cooler on 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 the cold water will automatically begin to circulate.
7. Sit back and enjoy the ride.
other tips
* With the regular (non-motorized) version of the cryo cuff, your body heat will eventually warm the water before you finish using it. If this happens, simply lower the cooler under the hose to remove the warm water, then repeat steps 4 and 5 above.
* If you find that there is too much pressure, or you feel tingling or numbness, turn down the cooler little by little until the cuff feels more comfortable.
* If you have a bandage or bandage of some kind around your knee, make sure it is not too tight before securing the brace to your knee.
Important: This is an overview of how to use it. You should always refer to your owner’s manual for specific instructions.
They’re worth it?
Some people will say that using ice packs (or even a bag of frozen peas) is all you need to reduce swelling and pain. In some circumstances, they are correct, and simple cold therapy may suffice. However, other situations may call for more than just icing. The added benefit of compression may be necessary depending on your situation. To determine what you need, it is crucial that you consult a doctor.
