McDavid Knee Brace, Maximum Support with Polycentric Hinges & Cross Straps, Comfortable Compression & Extra Stability

I have purchased a lighter duty unit - NEENCA Professional Knee Brace - first https://www.amazon.com/gp/product/B07R62C645. It was providing some good protection for light walking. It was helping me. I then went to the orthopedic doctor for my bad knee which had prior torn ligaments. He recommended a better brace for heavier use - rough surface hiking and sports. They showed me the unit they were going to get for me. Since I looked for the current brace, I knew Amazon had braces that would work just as good as the $750 unit they recommended. (I had other braces years ago which were very uncomfortable.) There are different versions and sizes that I had to deal with. My wife said at these prices, for $50 I could take the chance trying out difference styles and sizes.After much reading of reviews, I determined this is would probably work fine. I liked the one with interchangeable hinge, but I have one lighter duty unit already. This seem reasonably compact, has knee cap protection and seem like it would be comfortable since the fabric stretches rather than fold below the strap. My analysis turned out to be correct. I now can perform exercises like elliptical with good support and it was comfortable, more than the bulky older braces I had in the past.There are a few things you have to be aware: this is elastic and will be tight against you leg, when you sweat in it, it will be somewhat difficult to remove. It is suggested to be only worn for a couple of hours, you should not wear it all day, especially to sleep. I wear the other lighter unit all day when I go to work, I would not wear this one. Finally, these are wear item, even the $750 medical version. How long it lasts, depends on how much you use it.For the savings, I rather have this and other lighter versions rather than the expensive medical unit I wouldn't wear often like the two combination I have bought. BTW, my knees are getting better with my combination.
