McDavid 422 Knee Brace Review

Debilitating medical conditions like arthritis, osteoarthritis, previous soft tissue or orthopedic injuries, and other physical ailments can cause pain and inflammation in your knees. If you have ever experienced this, you probably know that our legs are some of our most precious assets. Luckily, there is a way to protect your knees, and it’s as simple as a wearable device.

In this post we’ll be giving you an in-depth look at the McDavid 422 Knee Brace with dual disk hinges, and show you how it can help you recover from a knee injury and possibly help you avoid any further damage to the area.​ This knee brace was picked by us as one of the best knee braces for basketball, as well as football, but in this article we will provide more general information about the brace itself, rather than a sport-specific context.

McDavid 422 Knee Brace Specs

The McDavid 422 is categorized as a Level-3 Maximum Protection knee brace, which means that it provides good limits on the range of motion in your knee, which in turn can eliminate any unnecessary movement that might worsen a preexisting condition. Support and comfort are guaranteed with this knee support brace, and the fact that it can be worn on either the left or right knee means that it’s also quite versatile.

Most people appreciate the fact that the McDavid 422 comes with two adjustable support straps and also that it's manufactured from latex-free neoprene and nylon fabric, which adds to its durability and comfort factors. It comes available in sizes Small to XXL.

The McDavid 422 Knee Brace in Action

The McDavid 422 promises ultimate protection with its padded buttress and dual disk hinges. What we really appreciate is the fact that this knee brace doesn’t work with gears (like a lot of its competitors), but instead operates with two independent side arms, which is great because it eliminates an injury risk when hyper-extension accidentally occurs. The fit on the arm is padded, which ensures that you’ll have a fit that’s non-restrictive.

To help maintain your knee’s strength, the McDavid 422 sports wider hinge paddles, and they’re also some of the lightest paddles ever used on knee braces, so you can be confident in the fact that this brace won’t wear your knee down even more.​

Forget about fit problems, because the McDavid 422 knee brace has two adjustable hook-and-loop straps, allowing you to adjust your brace according to your specific needs. The fact that it’s adjustable means that the McDavid 422 is a great choice for individuals that need to ensure they’ll have a pressure application. Compression is also one of the safest and most pain-free ways to get rid of swelling and inflammation, which can also facilitate a more comfortable recovery process.​

The brace’s neoprene material ensures that you’ll be treating you knee with heat retention and thermal regulation, almost like therapeutic heat application. This helps ensure that blood flow is promoted, which in turn leads to a faster recovery time.​

Therefore, it's easy to think that the McDavid 422 isn’t as great with air-flow since it retains heat, but it’s really a superstar when it comes to breathability, and since it’s latex-free, even those with sensitive skin can use the brace without the fear of skin irritations.​
