You might be wearing ‘ol blue until your doc says you can start with increasing your ROM which usually occurs at week 6 (at least that was the case with me). The orthopedic doctor should then suggest the brace in the next picture which usually consists of 4 Velcro straps, telescoping bar for customized length and a slide lock mechanism on each side of the knee that allows you to select a specific degree of ROM. This brace will serve you for the rest of your rehabilitation.
PLEASE NOTE!
These are fabulous braces and are very stable but come with a very hefty price if you buy them from your doctors office. I believe I paid $275 or more for the very first one, but then later quickly realized you can get them on eBay or Amazon for almost half of the cost. I would buy two of them just to have a backup. You will pay more for different name brands. The two that I like best are the BREG and Orthomen, but don’t buy them on their website. Purchase your leg brace on either eBay or Amazon or elsewhere online. I would recommend buying it on Amazon due to their fast shipping and you want your leg brace sooner than later.
I highly recommend, if you do receive the big blue brace after surgery or after your ER visit, to ditch it and quickly purchase the telescoping ROM flexion leg brace described above. Buy one or two better yet two of them here and you will be so happy you did. Not only are these braces more durable and stable for your leg(s), but they also doesn’t wrap your leg like a cocoon making your leg extremely hot and sweaty.
