Sizing Information

Measure the knee for which you are buying the brace. Standing, bend the leg no more than 45 degrees, and with a flexible tape measure, measure around the largest part of the knee, directly over the patella. (If a flexible tape measure is not available, measure with a string or other flexible material and mark the measurement, then lay over a ruler).



Dual medial and lateral steel stays create solid joint stability in the knee.















This neoprene knee brace with steel stays provides a high level of support, extra long compression sleeve, and fits either the right or left knee. The neoprene material is 0.1875 inches thick, for therapeutic heat retention and soft tissue compression, while two-sided nylon construction ensures long-lasting durability. A padded buttress, two medial, and two lateral stays create solid joint stabilization. Two Velcro straps and four elastic crossing straps provide additional ligament support, and a newly redesigned wide back allows for increased mobility and ease of motion.

This support is worlds above what you can buy at drug stores. It offers extremely good quality and the criss/cross straps are what most people need to support weak knees. Ignore what others have said about the sizing. McDavid's chart is spot on. Neoprene supports are supposed to be tight. That is how they work. The upper and lower straps are there to prevent slippage and the cross straps put pressure above and below the patella for tracking. I know of what I speak. I have been an athlete for 40 years and I have used many supports. Recently I was diagnosed with severe arthritis in my right knee (due to an old injury) and after surgery and recovery I have been looking for a good knee support. I believe I have found it in the McDavid Ligament Knee Support. Once again, do not listen to those who have say it runs small. It does not! Tight is Right!!

The 425 knee brace "WAS" the best knee brace I have ever had! I'm a very active recreational basketball player, I have minor torn meniscus in both of my knees. So, being a very athletic active guy, I have unstable knees! The old design had the cross straps start from behind the knee and come together at the top of the thigh and shin. The new design has the cross straps start at the MCL and LCL ligaments. I find this design to be flawed because, Neoprene...the stretchy material that it is...when you go to tighten the cross straps, it actually pulls the two medial/lateral rods on the side forward towards the knee cap, leaving MCL and LCL ligaments susceptible to injury! Furthermore, if you have torn or worn down meniscus cartilage which causes the knee to be unstable during instance activity...if you have the straps pulling the rods forward, all your really doing is stretching the neoprene fabric in the back and causing the front to bunch up as your being active! However, if Mcdavid had stuck w/ the original design, then the straps would come over the rods keeping them in place and support unstable knees because the cross strap would cover the entire knee from back to front, offering the "level II" support that they claim!

Mcdavid says that the new design is more comfortable w/o the seamless back! I don't feel a change in comfort...and, i'd take the seamless back over a torn ligament or a slip knee any and every time!!!

Mcdavid, you "HAD" the perfect product! At a very economical price too!

I wear one all day. Improves my condition by about 50% to 75%. Takes a little getting used to when mountain bike riding. While wearing it during the day I have to remember not to bend my leg too much, while sitting, to stop my leg from falling asleep (same feeling when an arm goes numb from sleeping on it). I bought a total of 4 because I need a clean one after mountain bike riding.

I found that the sizing chart, on the McDavid web site "mcdavidusa.com/store/zoom1.asp?SIZING_ID=69", to be one size too small. I measured my knee, while straight at 15 ½ inches and fully bent at 17 inches. This implies a "Large" size but I had to get an X-Large.

My daughter-in-law, who is a kinesiology expert working with a major college sports program and who has had her share of knee problems recommended two products, this being the one I selected. My selection process is one recommended by other reviewers:

Step one is to get a real diagnosis for your problem since the knee is a complex joint and different conditions benefit from different devices. I had knee and hip scans.

Step two, was to confirm the need for support below the patella, the need for type two level of lateral support and stability as well as the need for compression and warmth.

Step three: finding the best device possible at an acceptable cost. I read plenty of the reviews for plenty of the products marketed on Amazon and visited some manufacturers sites before giving up and asking my daughter-in-law. At least I had already pieced together an idea of what sort of device would work for my condition.

Step four: the very important process of visiting the manufacturers site to look at sizing and measuring instructions for S, M, L and XL circumferences of the knee. Stand up straight and use a cloth tailor's measuring tape. Get someone to help you to get a good measurement. Sizes are for two-inch ranges with this product but other manufacturers have differing size range measurements. Be aware that the basic sleeve part of these devices must fit snugly in order to provide compression and part of the support. It may take time for new brace users to tolerate the pressure and the feeling of the elastic fabric on the back of the knee. I agree with many reviewers of this type of product that the manufacturer is almost always right in sizing. This company is...even for me with my short(er)legs and heavy thighs and muscular calves.

"Two Velcro straps and four elastic crossing straps provide additional ligament support; redesigned wide back allows increased mobility and motion."

This brace has been redesigned - I have an old one that I got at least 5 years ago. This new brace has improvements in cuff shape, so it fits onto the leg better, and it also has a smooth rear panel - both of which makes the brace very comfortable.
Where MdDavid messed up is with the four elastic crossing straps that surrounds the knee. This is what separates the 425 from the standard 2-strap brace, and is why somebody would buy this brace. With the old brace design, the four elastic crossing straps are connected together on the back of the knee and wrap around to the front, completely surrounding the joint - it feels like your knee is in a vice - it is extremely supportive and effective. The new design has the straps connecting only halfway around the knee - sharing the seams where the new wide back panel is sewn in. The end result is that all 6 straps float on the front of the knee, so the overall support is gated by the tension on the wide back panel, which is smooth neoprene with no additional reinforcements. Worse yet, the diamond straps cross each other before connecting at the rear-panel seam, so the tension put on them creates a wrinkle across the rear panel. As such, even with all of the extra stuff put on, the brace offers no more support than the simplest of un-strapped neoprene wraps.

Bottom line - don't buy it. It is a shame that they messed up the core of the brace design by moving the strap connection points, because the new cuff design IS very comfortable. If the four elastic crossing straps connected in the back as in the old design, it would be a wonderful brace.
