Knee braces are popping up all over the gym these days in all sorts of colors and designs. Many brands have infused copper in the material and make claims that may or may not be substantiated by scientific studies. The Federal Trade Commission has fined at least one knee brace company because of outrageous marketing techniques and false propaganda about their products.

Copper Fit manufacturers both elbow and knee compression sleeves infused with copper. They also sell compression socks, shoe inserts, and back brace. The company claims that their items provide support, reduce recovery time, improve circulation, prevent strain and reduce odors. 

Generally, customer satisfaction ratings for Copper Fit knee brace reviews are middle-of-the-road between three and four stars. Let’s take a closer look at some things to consider before buying a knee brace.

What Is A Knee Brace?

A knee brace is a device designed to support proper knee functioning. Braces come in a variety of different styles with different purposes. 

Functional braces are often worn after a significant injury to the knee has healed. They stabilize, support, and control the knee to prevent further damage. 

Rehabilitative braces are typically only used for a few weeks after a severe injury or surgery. They are designed to allow limited movement of the joint while the knee is healing. 

A range of motion knee braces is also often used post-operative during the recovery period. People with hyperextension issues or contractures may also wear this type of device. They have hinges that allow for a proper range of motion without overextending.

Unloader braces are specifically designed to help relieve pain for people who have arthritis in their knees. The brace shifts the weight, unloads it, from the painful section to a stronger area. They have an adjusting dial that is used for this purpose.

Prophylactic braces are used by athletes to protect their knees from injury during a session of high contact sports. 

Hinged knee braces are meant to stabilize the knee after a sprain and reduce pain in someone with mild arthritis or after sustaining a minor injury. They are made from neoprene and can either be pulled on or wrapped around the knee. They often have velcro and built-in metal hinges for support. 

Patella stabilizing braces, also known as Patellofemoral braces, have extra padding around the knee and are hinged. They are designed to provide more lateral knee support than other types of braces. 

Knee sleeves are not braces but offer support by providing compression around the knee joint. They pull on, like a sleeve, and have no hinges. They are made from elastic material or neoprene and have elastic bindings to keep it in place. 

Do Knee Braces Work?

Generally, functional and rehabilitative braces work better than other types, including knee sleeves. These braces help some people more than others. In some instances, using a knee brace might cause more injuries, especially among athletes that place a lot of strain on their knees during training and performance.

Although Copper Fit has several other products, their compression knee sleeve is by far the most popular. It is not technically a knee brace because it does not have any struts, hinges or mechanical supports although often the terms are used interchangeably.

Copper Fits compression sleeves are made from 82% polyester, 14% spandex jersey and 4% copper ion fiber. The fiber composition is high-wicking and modacrylic. The copper ion fiber is woven into the sleeves to reduce bacteria growth that causes stains and odors. 

Copper Fit compression sleeves are designed to be used by both the average person and the professional athlete to decrease muscle recovery time, reduce muscle soreness, and eliminate aches and pains.

According to Copper Fit knee brace reviews, customers are generally satisfied with the product but have had issues with correct sizing.

What Are Compression Sleeves Made Of?

Knee sleeves are typically made with neoprene, spandex or fabric. Neoprene is a synthetic rubber and has a strong odor. Fabric knee sleeves do not smell but tend to lose their elasticity and thus not work as a compression device. Spandex allows the knee sleeve to stretch but may not give you as much support as you would like.

There are known health benefits to using a compression sleeve.  Wearing a compression knee sleeve for up to 24 hours after exertion can significantly decrease knee soreness. 

Compression knee sleeves have been shown to reduce arthritis pain when worn allowing for less pain when doing normal, everyday activities for people living with arthritis.

Compression sleeves have also been used successfully to reduce pain during physical therapy work with patients that have patella pain, runners knee or anterior knee pain.

The improvement a person experiences from wearing a compression sleeve is believed to be due to proprioception, body position and sense of movement. The heat generated by wearing a compression sleeve may also be beneficial by increasing blood circulation to the area. 

For the more athletic, compression garments have been shown to increase running performance, maintain leg power and assist with post-exercise recovery time.

What Are The Benefits Of Copper?

Although Copper Fit makes no direct claims that the copper infused into their compression sleeves is for anything other than odor reduction, they capitalize on the long-held belief that copper has medicinal value. Copper Fit’s Pro series outlines the joints encased in the compression sleeve in copper coloring, again, drawing attention to the copper component.

Wearing copper for joint and arthritis pain is a common folk remedy. It is believed that bits of the copper rub off onto the skin and then are absorbed into the body. There has been no scientific proof that this is true. 

Copper does have health benefits including inhibiting the growth of bacteria and other microorganisms. Whether or not bacteria inhibition translates to odor control, is an entirely different matter. Copper, when ingested as part of a healthy diet, helps the body utilize iron and supports nerve functions.

What Factors Should You Consider Before Buying A Knee Sleeve?

If you have had a minor knee injury, a knee sleeve would be adequate protection. However, if your knee injury is more serious, and includes torn ligaments, you will need a device that is more robust, like a knee brace. If you are unsure, ask your doctor before purchasing one of these items.

If you plan on using your knee sleeve during strenuous activities, you’ll need a more flexible material which might mean the compression device isn’t as sturdy as you would like. Knee sleeves that are designed for support are less flexible. 

Finding the right size is extremely important. A knee sleeve that is too small will cut off the circulation to that area and make your injury worse. One that is too large won’t provide the proper support. Most companies have a sizing chart to help you choose the one that fits you appropriately. 

If you purchase a knee sleeve and find that it doesn’t work for you, you may be throwing money away if you have purchased one from a company that does not provide a satisfaction guarantee.

What Can You Realistically Expect A Compression Knee Sleeve To Do?

As we mentioned, according to doctors functional and rehabilitative braces work better than knee sleeves for most conditions. If you have sustained an injury, have recently had knee surgery or have debilitating arthritis, a knee sleeve is not the device for you. 

If you have occasional knee pain after a workout, have mild arthritis or developed runner’s knee, a knee sleeve might help. Knee sleeves lose their compression ability over time, so you’ll need to replace them regularly. How often you need to replace your knee sleeve depends on the quality of the material and frequency of use.
