Glad we purchased these braces for my son
The coach recommended these for our players this season. I purchased two for my son so he would be protected as he plays right tackle on the line.

Donjoy Armor Knee Brace
I use it playing hockey, very comfortable, I feel like I won't injure my knee when I wear it.

Donjoy Armor Knee Brace
very good no problems I use it for hockey

Son loves your brace
Just received the Armor and my son loves it - thanks!
Durable braces
I had the Forcepoint hinge version after ACL replacement about 6 years ago. I have been wearing those braces for 6 years riding dirt bikes and they are finally starting to show their age. No doubt what I was going to replace them with the same, but instead went with the standard hinge this time around. Love them!
Helped my son
We bought these for our son who plays football and loves to go skiing also during the winter. He injured his knee last year and had avoided sports as his knee would buckle. According to the orthopedic doctor he damaged his meniscus and partially tore his MCL/ACl so we got these through DME-Direct. He is 6'2" tall so I got him the Standard length in the combined instability strapping to give him more protection. He used it last week on a ski trip and it saved his knee he said.
Didn't fit me...but
It didn't fit my leg - all of my measurements were not within the size I chose. DME-Direct was great - they took back the brace AND got me into another brace that fits my leg size and shape perfectly. Thank you!
Protected now and more active
Brace fits well. I have a bad knee and this brace has allowed me to be more active and more protected. It is very sturdy. I bought the short calf length style ACL fr my right knee and I'm very pleased with the customer service and the product.
Replacement for old braces
5/5 stars. Replaced my son's old braces with a new pair for this football season. Bought through DME-Direct and they arrived the next day - surprisingly faster than through Amazon. Very pleased!
Good purchase to protect my son...
I needed to get braces for my son who plays football and read plenty of reviews for Donjoy armour knee brace and finally got him a pair as they were on a good sale here. The price was fair and the shipping was very fast - our order arrived a couple of days later. He has been wearing them at practice now everyday and reports thay are helping to protect his knees during practice and scrimmagees. Recommended
