Happy with the 422 Mcdavid brace
Just bought another pair to protect my knees from all of the twisting I place on them with my martial arts training. After having surgery for meniscus tears in both knees I protect them to keep from re-injuring them and that means wearing knee braces like these with hinges for maximum support.

Very impressed With This Brace
The reviews are all consistently good when it comes to the McDavid Dual Disk Hinged Knee Brace no matter where you read them. This support has been around for a while and the quality of the materials speaks well for the brace. I wear mine 3 times a week when I play basketball and it helps keep my trick knee from buckling out on the court. The 422 only comes in black but it's stylish, durable, and does a great job stabilizing my knee joint.

Large Not Large Enough
I ordered the size Large but it didn't fit even though I followed the sizing chart. Had to exchange it for the XLarge. The exchange ran smoothly and I'd definitely buy my next one from here.

Exactly what I needed
Exactly what I needed. The XLarge fit my knee perfectly and I've experienced more knee stability since using my dual disk knee support. The compression and support have helped my knee from not giving out when I'm walking. I'm buying a second McDavid 422 to have as a backup.

True to size
This is a great, solid brace. I upgraded my knee braces this winter for snow sports including skiing and this does exactly what I need. The brace features sold construction but won't slow you down and is very well padded inside. There's no bounce with this brace so if you race you might want another brace that's different, but this 422 will do a very good job preventing knee injuries so its a bargain at this price. Measure carefully - this McDavid dual disk 422 is very true to size.

Bought it for my girlfriend
I bought this brace for my girlfriend and she has reported not having any knee pain while using it. She said it really stabilizes her knee problem when she's at work and on her feet all day.

Stabilizes the knee
This is exactly what I was looking for in a knee brace. The dual disk design stabilizes the knee joint and gives me the confidence that it's not going to buckle on me and "give out".

More support and Comfort than I expected
The brace is lightweight, sturdy and provides my knee with really good support. All of these qualities are much higher than I expected to receive with this product. Given its metal hinge feature, this brace is more comfortable than I expected as the neoprene quality inside is supurb.
