Hi Chiapet, I think it depends on your injury. If you have an X-ray or MRI or a diagnosis from your GP or specialist, I'd suggest taking it to an Orthotics clinic in your location. I had one type of knee brace for my right knee and have a different type for my left. Both braces are rigid braces made of metal and fiberglass. One lifted the interior compartment. The other lifts all compartments.
I know that doesn't help too much...but the Orthotics people in my area are great. And, the braces were expensive, but so worth it. I was able to keep playing hockey with the first brace for almost five years!
That's great! That doc should know if a brace would be beneficial, and direct you to an Orthotics clinic to get you measured or casted for a brace. Most insurance companies require a prescription and that the brace be rigid (made with either metal or something like plastic or fiberglass). My company covered a new brace every two years. Good luck at the Ortho appointment!
