What the Cube and Kodiak have in common

If you're deciding between these two, the good news is you can't really go wrong on performance. Both machines:

• Use the same compact cooler design and weigh about the same, roughly 14.5 lbs when filled with ice and water.
• Provide 6–8 hours of motorized cold therapy on a single load of ice.
• Circulate chilled water continuously through the pad, so the temperature stays steady for the whole session instead of warming up like an ice pack.
• Use static compression, meaning the straps hold the pad snugly against your knee. Neither one has the active, inflating compression of a cold + compression unit.
• Run quietly, so they won't disturb you while you rest between sessions.
• Are FSA/HSA eligible when used to treat a medical condition like knee surgery recovery.

Difference #1: The pads (WrapOn vs. Intelli-Flo)

This is the biggest difference, and the one that matters most when you're buying replacement pads or borrowing a machine.

Breg Polar Care Cube: WrapOn pads

The Cube uses Breg's WrapOn Polar pads. The water flows evenly through the pad, and elastic straps wrap around the joint to hold it in place. For the knee, the Cube offers three sizes, which is a big advantage if you have a larger leg or heavy post-surgical swelling:

• Regular Knee Pad (04700): 10.25" x 11.25"
• Large Knee Pad (04703): 11.5" x 12"
• XL Knee Pad (04705): 12.25" x 19"

Not sure which size you need? Watch our Breg Polar Care Cube Knee Pad Sizing Guide or read our knee pad size guide.

Breg Polar Care Kodiak: Intelli-Flo pads

The Kodiak uses Intelli-Flo pads, which are designed to deliver a temperature specific to each treatment area. For example, an ankle pad runs slightly warmer than a shoulder pad. For the knee, the Kodiak offers two pads, both 13.5" x 14":

• Intelli-Flo Knee Pad (10230), with two straps
• Intelli-Flo Compressive Knee Pad (10235), with a 60" compression strap that wraps around the knee for a snugger fit

The pads are not interchangeable

Cube pads won't work on a Kodiak, and Kodiak pads won't work on a Cube. The two machines use different pad connectors. If you're borrowing or renting a Breg machine, or ordering replacement pads, check which machine you have first:

• Kodiak: Breg Polar Care Kodiak Intelli-Flo Replacement Pads

Difference #2: Battery power (Kodiak only)

The Kodiak can run on an optional Kodiak battery pack ($86.99, uses four AA batteries) instead of a wall outlet. You can also buy the Kodiak with the battery pack included ($280 with a knee pad).

The battery is handy if you want a cold therapy session away from an outlet, such as in the car on the way home from surgery, on the couch across the room or after a physical therapy visit. The Cube doesn't have a battery option and must be plugged in.

The battery doesn't change how you use the machine: you still follow the 20 minutes on, 20 minutes off protocol, and you never sleep with the unit on.

Difference #3: Price

The Cube costs about $31 less with a knee pad. Both are FSA/HSA eligible.

Which one is better for knee replacement?

Both deliver the same hours of steady cold therapy, so the choice comes down to fit, portability and budget.

Choose the Breg Polar Care Cube if:

• You want the lower price.
• You want a knee pad matched to your leg size, especially the Large or XL pad for a bigger leg or heavy swelling.
• You'll mostly use cold therapy at home near an outlet.

Choose the Breg Polar Care Kodiak if:

• You want the option of battery power for use away from an outlet.
• You like the idea of Intelli-Flo pads with a temperature tuned to the knee.
• You want the compressive knee pad with a longer strap for a snugger fit.

Always follow your surgeon's recommendations. If your surgeon or hospital specifies one machine, stick with it so your pads and dressings match.

Which one is better for shoulder surgery?

For shoulder surgery, such as a rotator cuff repair or shoulder replacement, the Cube and Kodiak are very close. Both offer a Regular and an XL shoulder pad, and both use the same sizing rule: choose the XL pad if your chest measures 42 inches or more, male or female.

Why you might choose the Cube:

• It's $31 less with the same two shoulder sizes and the same hours of cold per load of ice.
• It's a simple, reliable choice if you'll mostly ice in one spot at home near an outlet.

Why you might choose the Kodiak:

• Shoulder patients are usually up and walking soon after surgery, so the optional battery pack makes it easier to use cold therapy away from an outlet.
• Its Intelli-Flo shoulder pads are designed to deliver a temperature tuned to the shoulder.

Why it may not matter much: with the same pad sizes and nearly identical performance, either machine is a good choice for shoulder surgery. Pick based on budget and whether battery power matters to you. For help with sizing, read our guide on how to size Breg Polar Care shoulder pads.

Many shoulder patients rest in a recliner after surgery. Whichever machine you choose, follow the 20 minutes on, 20 minutes off protocol and never sleep with the unit on.

Which one is better for hip replacement?

For hip replacement, we recommend the Kodiak for most patients, because its hip pad is much larger than the Cube's.

Why you might choose the Kodiak:

• Its 13" x 20" hip pad covers far more area than the Cube's 11.5" x 12" pad, which helps cover the outer hip, the incision area and the upper thigh where swelling often collects after a hip replacement.
• Its longer 48" waist strap fits a wider range of body sizes.
• The optional battery pack lets you use cold therapy away from an outlet.

Why you might choose the Cube:

• It's $31 less.
• Its smaller pad can be a good fit for a smaller frame, or if your surgeon wants cold focused on a smaller area.

Why you might not choose the Cube for hip replacement: if you have a larger frame or want the most coverage, the Cube's smaller pad and shorter 44" waist strap may not cover as much of the hip and thigh. If a strap is too short on either machine, our Omni Ice Universal Cold Therapy Straps can help hold the pad in place.

Accessories for each machine

Safety tips for both machines

Follow the 20 on / 20 off rule. The universal protocol is 20 minutes on, 20 minutes off. Please speak to your physician or physical therapist for your specific instructions. And never sleep with the unit on. See our cold therapy schedule for home recovery for more.

Use a sterile dressing right after surgery. Surgeons, hospitals and surgery centers will not place anything over a fresh incision that isn't sterile. Use the sterile dressing that matches your machine and pad (see the accessories table above). Learn more in Why You Should Always Use a Sterile Pad with Cold Therapy.

Then switch to a skin barrier for the rest of your recovery. You'll only use sterile dressings for a short time right after surgery. Once your surgeon has cleared your incision, switch to a reusable non-sterile skin barrier for everyday sessions. Never let a Cube or Kodiak pad touch bare skin.

Use freeze bags, not loose ice or water bottles. Loose ice melts fast and needs constant draining. Frozen water bottles can crack the pump housing and block the water intake, and their paper labels and label glue break down in the water and can clog the pump, which can void your warranty. Reusable Omni Ice Freeze Bags freeze flat and fit around the pump in either machine.

Check your skin. Nerves around your incision may be numb after surgery, so you may not feel when it's too cold. Check your skin between sessions, and stop and call your surgeon if you notice blistering, burning, unusual color changes or numbness that doesn't go away.

Frequently asked questions

What's the main difference between the Breg Polar Care Cube and Kodiak?

The pads and the power source. The Cube uses WrapOn pads and offers three knee pad sizes. The Kodiak uses Intelli-Flo pads designed to deliver a temperature specific to each body area, and it offers an optional battery pack. Otherwise, the two coolers are nearly identical in size, weight and hours of cold per load of ice.

Can I use Breg Cube pads on a Kodiak, or Kodiak pads on a Cube?

No. The Cube and Kodiak use different pads and connectors, so the pads are not interchangeable. Always buy replacement pads, sterile dressings and skin barriers made for your specific machine.

Which is better for knee replacement, the Cube or the Kodiak?

Both work well after a knee replacement. The Cube is the better fit if you want a lower price or need a Large or XL knee pad for a bigger leg or heavy swelling. The Kodiak is the better fit if you want battery power or the compressive knee pad.

Which is better for shoulder surgery, the Cube or the Kodiak?

They're very close. Both offer a Regular and an XL shoulder pad, and both use the same sizing rule: choose XL if your chest measures 42 inches or more. The Cube costs less, while the Kodiak adds the option of battery power for use away from an outlet.

Which is better for hip replacement, the Cube or the Kodiak?

For most patients, the Kodiak. Its 13" x 20" hip pad is much larger than the Cube's 11.5" x 12" pad, and it comes with a longer 48" waist strap. The Cube can still be a good, lower-cost choice for a smaller frame.

Does the Kodiak get colder than the Cube?

No. Both run at an average pad temperature of 45°F or warmer when used with a Breg dressing. The Kodiak's Intelli-Flo pads are designed to tune the temperature to each body area rather than simply run colder.

How long does the ice last in a Cube or Kodiak?

Both provide about 6–8 hours of motorized cold therapy per load of ice. Using freeze bags makes swapping easier and keeps water from spilling.

Is the Kodiak battery pack worth it?

It's worth it if you want cold therapy away from an outlet, such as in the car after surgery or in a room without a nearby plug. If you'll mostly use your machine in one spot at home, the Cube or a plug-in Kodiak works just as well.

How long should I use a cold therapy machine after knee surgery?

The universal protocol is 20 minutes on, 20 minutes off. Please speak to your physician or physical therapist for your specific instructions. And never sleep with the unit on.

Are the Cube and Kodiak FSA/HSA eligible?

Yes. Both machines, their pads, sterile dressings, skin barriers and freeze bags are generally FSA/HSA eligible when used to treat a medical condition like knee surgery recovery. At Supply PT, you can check out with your HSA or FSA card just like a credit card.
