After having suffered an injury or getting surgery for that injury, your doctor or physiotherapist may encourage you to apply ice to the affected area. This practice isn’t limited to major injuries and surgeries either; we’ve all been in a situation where we’ve bumped our head or some other body part really hard to the point where a bruise starts forming. When this happens, whether you’re a kid in school or an adult at work, people will encourage you to put ice or even a bag of frozen peas on it. They never seem to explain why you should put ice on it, but we still do it and oftentimes we feel better after doing it. Why is that? What does ice do to contribute to healing or soothing our injuries?


Many healthcare professionals believe ice to be a valuable tool that can help patients with pain management and recovery.[1-7] At Curovate, we also believe in the effectiveness of this practice, especially for Hip and Knee replacements as well as ACL tears and reconstructive surgery. In this blog we’ll run through specific benefits of ice that may help you recover from a total hip replacement or knee replacement, or an ACL injury or surgery.


Pain Management


You probably already know that ice is a great numbing agent; like when you start to lose feeling in your fingers and toes when you’re out in the freezing cold. The biggest case for the use of ice for your recovery is that it will greatly reduce any pain you will feel after a surgery.[1-5] Studies have found that people who use ice to treat pain after surgery had a significantly reduced need for pharmaceutical painkillers.[8] This is great news, especially considering the opioid epidemic we’re facing right now. There is a consensus in the medical and research communities that we must limit the use of opioids and other pharmaceutical drugs to treat people for pain and that ice is an effective substitute.[8]

There are a few reasons that might explain why applying ice is such an effective painkiller; according to one study, a reason could be that the cooling effect of ice increases your pain threshold and tolerance.[6] Another factor could be “sensory nerve inactivation”; basically slowing or stopping the pain signal from traveling to your brain.[6-7] Ice can also contribute by stimulating your brain to release endorphins which are essentially ‘happy hormones’ that will counteract the pain you would normally feel.[6-7] Ice contributes to reducing pain in many ways and, while those contributions aren’t fully understood, we can still safely recommend applying ice indirectly to an injured body part.

Reduced Swelling and Inflammation


Another benefit of ice is that you can use it, combined with compression, to reduce swelling in the injured area. The Mayo Clinic defines swelling or “edema” as: “excess fluid trapped in your body's tissues”.[9] This happens usually in response to some injury as well as after surgery; it’s a normal part of the healing process. However, when you get injured, swelling is often accompanied by inflammation which includes sensitivity, redness, and heat;[10] it can be very painful. Using ice will numb the pain while compressing the area will drain it of the fluid that’s causing the swelling and inflammation. Just another benefit of icing the affected area after a total hip or knee replacement, or an ACL tear!


Conclusion


Essentially, ice is a non-invasive, accessible, and non-addictive alternative to painkillers and other medications used to alleviate pain and swelling in people who have had total hip replacement or knee replacements, ACL tears, and a lot of other musculoskeletal injuries and surgeries.[1-8] The amount of time that you should ice your injury will depend on what your healthcare professional recommends, usually 10-20 minutes. Much of the evidence for the amount of time you should ice is highly based on clinical results and there should be more studies to confirm this time range.[11] Remember, icing is generally safe but it’s always safest to consult your healthcare professional for advice before icing your recently-operated or injured area. And remember if you have had surgery and are using ice, keep your knee or hip clean and dry while applying ice for pain relief.
