OssurCold Rush Therapy Machine System with Knee Pad - Ergonomic, Adjustable Knee Ice Pack Wrap - Quiet, Lightweight Ice Pack for Knee - Strong Cryotherapy Ice Machine for Knee After Surgery

I have had to have a total knee replacement 4 times. Needless to say, I have lots of experience in post operative care for knee replacements/revisions. I have used this device 3 out of the 4 surgeries. In my opinion, it is worth the investment both in regards to aiding in healing by reducing swelling but also cost. It is a bit pricey but well worth the investment, as it can be easily stored and reused. As I have stated before, I've used this device 3 different times. The only difference was I rented it for what I could have bought 5 of these devices for. The only real downfall would be the amount of ice it requires to keep your surgical area cool. I have found that if you freeze 4, 16oz bottles of water, you can place 2 in the device with additional ice, and rotate them as needed. Even using frozen water bottles, you will still need to use ice. It is a pain to keep the ice on hand, but we kept it in the garage in our large cooler. I absolutely LOVE this machine and would highly recommend it to anyone having surgery where you would use an ice pack to reduce swelling. At my 1 week post op appointment, my surgeon and physical therapist couldn't believe how little swelling I had. Im now at my 3 week post op date and I still use it at night. Oh, it is super quiet. You won't even know it is on.

We purchased this item for post-knee surgery recovery for a torn ACL and meniscus. The product was very easy to set up, got cold almost instantly, and kept ice water in it, staying cold for easily 8 hours or longer when used with their given ratios. The machine does take a LOT of ice to have such a long-lasting cold. We had our freezer just full of ice trays and ice bottles and the like to be able to run this twice a day, and frequently put less ice into the machine than suggested. However, it still worked beautifully (just for more like 4-6 hours when the ratio of ice to water wasn't has high.Advantages of this cold therapy machine over traditional cold packs were that on the body, the machine's pad was lighter and colder than traditional ice packs, and conformed to the shape of the knee better. It held its cold temperature longer. Downsides were that the tubing sweats a bit, and so we would have a damp spot on the floor after hours of use, so we learned to use towels. Also, being stuck to tubing means not getting up as easily or frequently. For these reasons, it is nice to have traditional ice packs as well, for faster and more mobile cold therapy.We also noticed that cold therapy was needed right after the surgery for some weeks, then we didn't need it as frequently for a time. Once going weight-bearing on the knee again, we were glad we hadn't rented and returned a cold therapy machine, because knee swelling returned. We now know that this was an expected part of recovery, and that a return of swelling phase can appear 6 or more weeks into recovery, making a rental a 2+ month necessity at least. (If renting, that means it would have cost $600+!)Overall, we were thrilled with how well this cold therapy machine worked, and will keel it in the family for future injuries. Compared to the $300+ per month that medical rentals run (even with insurance), this was more economical, and it's nice to know we can keep it for future use or sell it to recoup costs.

We purchased the unit in 2022 for a knee replacement recovery. Seemed to work well. Second knee was done in Dec 2024 and to my surprise the unit leaks , badly, from somewhere in the hose. The pad leaks too but that can be considered a consumable item. Sadly the product is designed to be non-serviceable. You are expected to buy another one. CS says it's a one patient, one time use item. For $200USD?? Not in my book.I will buy something more robustly designed that actually has an insulated tank, which this product does not. It's simple concept. Tank, pump, hose and a heat transfer pad. How any EU firm can screw that up as badly as this is beyond belief!DO NOT BUY THIS BRAND!

My husband had a total knee replacement three + weeks ago. Post surgery, we initially naively thought that we could make do with the gel ice packs we already had on hand in the refrigerator. No way! A few days in, we ordered this machine, and it came rapidly. (Thank you, Amazon Prime!) It provided instant relief, helped with pain & swelling management, and was overall a huge improvement in the recovery process. It's worth every penny, in our estimation! The machine is unbelievably quiet and performs efficiently. We are using the knee pad. A few tips: 1) We read other reviewers' recommendations to use frozen water bottles instead of ice. This worked great for us! I missed the fact that they recommended using 8 oz water bottles, and purchased 16.9 oz bottles in error. Oops. No worries, though. I found that three of the larger bottles will fit in the unit just fine. They won't fit standing upright, but you can tip them over just a little bit and it works fine. I swap them out after several hours with replacements from the freezer. The unit is very well insulated and the water inside stays really cold. Because you are using the water bottles, you avoid the need to dump out the ice. Way better! 2) The lid is very tight, but I got used to it. No big deal. 3) Make sure that the unit is placed up high, more or less at the same level as the patient. Try to minimize kinks in the tubing. 4) We did not find that we had any condensation whatsoever on the tubing, so didn't need the CPAP covers recommended by some reviewers. 5) We intentionally never disconnected the quick connectors on the tubing so as to not risk leaks. 6) The pad itself has one sort of fuzzy side and one smooth side. The smooth side goes down against the patient, and the fuzzy side goes up, to grip the velcro strips. This wasn't immediately obvious to us and took a few minutes to figure out. The instructions do not indicate what to do here. 7) The pad and the velcro straps are well designed, but are getting worn now after a few weeks of continuous usage. It would be nice if they didn't wear out so fast. 8) If I were designing the machine, I would add a quick connect close to the unit itself so that you could take off the tubing for storage when it comes time. That would be a design improvement IMHO.
