For post-surgical recovery, a cryotherapy device holds a steady therapeutic cold far longer and more evenly than an ice pack, and most devices add compression that an ice pack cannot provide. Ice packs warm within about 20 to 30 minutes and need constant replacement, which makes them better suited to minor everyday aches than to a structured surgical recovery. For knee, shoulder, hip, and other orthopedic procedures, surgeons typically recommend a cold and compression device for more consistent results.
If you are recovering from surgery, the question is rarely whether to use cold therapy. It is which kind of cold therapy gives you the most reliable result through the weeks that decide your range of motion.
The way you cool a surgical site shapes how your recovery actually goes. An ice pack and a cryotherapy device both lower tissue temperature, yet they deliver that cold in very different ways, and those differences matter most in the weeks when swelling limits your range of motion and drives your pain. This guide walks through the criteria that separate the two so you can choose the right tool before your surgery date.
How to Choose Between Ice Packs and a Cryotherapy Device
The criteria that actually decide the question, in the order most patients weigh them.
Both options have a place. An ice pack is cheap and sits in every freezer. A cryotherapy device is a rented system built for a recovery timeline. The right choice depends on how much consistency your recovery needs and how much effort you want the cooling to cost you each day. Work through the criteria below in order and the answer for your situation becomes clear.
Cost and what a rental actually includes
An ice pack costs a few dollars and a cryotherapy device does not, so cost is usually the first thing patients weigh. The fair comparison is what each one delivers over a full recovery. A NICE1 rental runs for an initial period of about two weeks and includes the device, the procedure-specific wrap, delivery through a local authorized distributor, and support if anything comes up. An ice pack covers none of that and asks you to manage the cooling yourself, around the clock, with supplies you keep replacing.
For a minor sprain or a sore muscle, that trade favors the ice pack. For a procedure where swelling control affects how quickly you regain motion, the rental is built to do a job the ice pack was never designed for.
Effort and consistency during recovery
An ice pack warms within 20 to 30 minutes, so holding a therapeutic cold means repacking it every half hour through the day and waking to repack it through the night. Studies of skin and joint cooling show that ice packs also cool unevenly, chilling the surface while deeper tissue stays warmer (Chesterton et al., 2002). A cryotherapy device holds one set temperature continuously and circulates it through an insulated wrap, so the cold dose stays steady without you managing it.
That steadiness is the practical difference. The recovery work continues whether you are awake, asleep, or finishing a physical therapy session, rather than stopping every time a pack thaws.
Surgeon recommendation and clinical validation
Surgeons recommend cold and compression devices after major orthopedic procedures for a reason. Intra-articular temperature studies have found that a circulating cryotherapy device produces deeper and more sustained joint cooling than ice (Warren and McCarty, 2004), and a meta-analysis of continuous versus traditional cryotherapy after total knee arthroplasty reported better swelling and pain outcomes with continuous cooling (Liu et al., 2023). The NICE1 has been used across more than 250,000 procedures and is trusted by orthopedic surgeons for post-surgical recovery.
How the options compare for your specific procedure
An ice pack is a generic shape pressed against a joint it does not fit. A cryotherapy wrap is cut for the anatomy you had operated on, so the cold reaches the knee, shoulder, or hip evenly rather than pooling where the bag happens to sit. If you are weighing specific rental models for a knee procedure, the breakdown in the best ice machines for knee surgery recovery compares the options side by side. The gap to keep in mind is that gravity-fed ice machines still depend on an ice fill and stop cooling once the ice melts, usually within one to two hours.
Timing and overnight coverage
Swelling does not pause overnight, and the hours you spend asleep are when an ice pack falls furthest behind. A device that runs continuously keeps managing inflammation through the night so you start each morning ahead rather than behind. Because the device ships from a local distributor, arrange your rental at least 7 days before surgery so it is set up and waiting when you come home. Ask your surgeon whether pre-surgical cooling is appropriate for your procedure, then arrange the rental once you have that answer.

How the three most common cold therapy options hold up across a recovery timeline.
| Feature | NICE1 (Iceless) | Ice Packs | Ice Machines (Gravity-Fed) |
|---|---|---|---|
| Temperature | Held precisely all session via thermoelectric cooling. No ice needed. | Warms within 20 to 30 minutes. Constant replacement required. | Depends on ice fill. Degrades as ice melts over 1 to 2 hours. |
| Compression | Programmable pneumatic. Adjustable by procedure and recovery phase. | None. | None on most models. |
| Overnight use | Runs continuously. No interruption needed. | Requires waking every 30 to 60 minutes to repack. | Runs until ice depletes. Typically 1 to 2 hours then stops. |
| Skin safety | Insulated wrap holds a set temperature, no direct ice contact. | Direct cold can injure skin or nerves if left on too long. | Insulated wrap, though cooling is uneven as ice melts. |
| Rental delivery | Local authorized distributors nationwide. Delivered before surgery day. | Any pharmacy. | National rental. Shipping required. No local support. |
For everyday aches and minor sprains, an ice pack still does the job. For a surgical recovery where the cold dose needs to stay steady through the day and night, a device built around that job is the stronger choice.
Why the NICE1 Is the Clinical Standard
A device designed for the recovery, not adapted from a freezer.
Your body already knows how to heal. The role of cold and compression therapy is to clear the swelling that gets in the way, so the healing it is already doing has room to work. A steady cold dose and active compression stack the deck in favor of the recovery you are working toward.
The NICE1 was built around that principle. It is an iceless cold and compression system that surgeons recommend and that patients use at home through the most important weeks of recovery. Here is what sets it apart from both an ice pack and a gravity-fed ice machine.
"For post-surgery recovery, I can't recommend NICE enough."
Dr. Tom Hackett, Orthopedic Surgeon and Partner, The Steadman Clinic
Consistent Cold That Holds Its Dose
Five fixed settings, each held for the full session.
The NICE1 offers five fixed cold settings, from 58°F at Level 1 down to 42°F at Level 5, the coldest. You select a level and the device holds that exact temperature for the whole session through thermoelectric cooling. An ice pack starts cold and drifts warm within half an hour. The NICE1 does not drift, so the therapeutic dose your care team intends is the dose you actually get.
Overnight Coverage Without Interruption
The recovery work continues while you sleep.
Inflammation keeps building overnight, which is exactly when an ice pack has long since warmed and a gravity-fed machine has run out of ice. The NICE1 runs continuously through the night with no refills and nothing to repack, so you wake up with swelling already managed rather than waking every hour to chase it.
Anatomically Designed Wrap
Cut for the joint you had operated on.
An ice pack is a generic shape held against a joint it does not fit. The NICE1 wrap is designed for the specific anatomy of your procedure, so the cold reaches the whole surgical site evenly instead of pooling wherever a bag happens to rest. Even coverage is what lets the cold do its job across the joint rather than at one spot.
Programmable Active Compression
Cold and compression working together.
Cold slows swelling and compression moves it. Neither an ice pack nor most ice machines offer compression at all. The NICE1 adds programmable pneumatic compression you can adjust by procedure and recovery phase, which is the same pairing the research links to better swelling and pain outcomes after knee surgery (Kazan and Görgülü, 2017).
Validated Across 250,000+ Procedures
Trusted by surgeons and patients at scale.
The NICE1 has supported recovery across more than 250,000 procedures and is used by orthopedic surgeons for post-surgical patients. That track record is the difference between a tool you hope works and a system already proven across hundreds of thousands of recoveries.
How to Rent a NICE1 Before Surgery
A short head start is all it takes to have it ready.
Start with your surgeon. Ask whether pre-surgical cooling is appropriate for your procedure and confirm that a cold and compression device fits your recovery plan. Once you have that answer, arrange the rental at least 7 days before your surgery date so the unit is delivered and set up while you are still preparing at home. The initial rental period runs about two weeks, which covers the window when swelling control matters most, and you can extend it if your recovery calls for more time.
Delivery comes through a local authorized distributor, so there is no waiting on national shipping and there is local support if you have questions. To reserve, use the rental form on this page or call NICE at 888.815.9907.
Frequently Asked Questions
The questions patients ask before they rent.
How much does it cost to rent a cryotherapy machine after surgery?
A NICE1 rental covers the device, the procedure-specific wrap, local delivery, and support for an initial period of about two weeks. Pricing and any insurance or HSA and FSA questions are handled when you reserve, so call 888.815.9907 or use the rental form on this page for current rates and what your plan may cover.
When should I arrange the rental before surgery?
Arrange it at least 7 days before your surgery date. Because the unit ships from a local distributor, that lead time makes sure it is delivered and set up at home before you leave for your procedure, so it is ready the moment you come back.
Which surgeries is cold and compression therapy used for?
The NICE1 is used across knee, hip, shoulder, and other orthopedic recoveries, including total knee replacement, ACL reconstruction, meniscus surgery, rotator cuff repair, and more. The wrap is matched to the joint you had operated on. Your surgeon can confirm whether it fits your specific procedure.
Can I use the NICE1 overnight while I sleep?
Yes. The NICE1 runs continuously through the night with no ice and nothing to repack, so it keeps managing swelling while you sleep. Overnight is when an ice pack falls furthest behind, so uninterrupted coverage is one of the main reasons patients choose a device over ice.
Is it better to rent or buy a cold therapy machine?
For a single surgical recovery, renting matches the cost to the weeks you actually need the device and includes the wrap, delivery, and support without a large upfront purchase. Renting also means you get a maintained, clinically validated unit rather than storing a machine you may not use again.
