The injury was bad. Torn ligaments or cartilage can be so painful. Perhaps you had to have surgery on your knee. Now you're stuck in a knee brace for six weeks or more. The immobility is enough to drive you crazy. Top that off with the fact that the brace isn't fitting right. This has got to stop! Knee braces are intended to add support to knees weakened from injury or debilitating diseases such as arthritis. The right brace can be an invaluable aid. Some braces are stretchy and just add a little support when you work out or walk or work. Others have supports in them such as rods that keep the knee from twisting or going sideways. The strictest of braces are meant to keep the knee in one spot and to restrict movement. No matter what brace you're using, it must fit right. An ill-fitting knee brace is very detrimental to the healing process. If your brace doesn't fit right, it can rub blisters on your leg. If it fits too tight it can cause tingling, numbness and even blood clots in your knee and leg. A knee brace that's too loose will shift and slide. It won't protect the knee properly. More injuries could result from a loose-fitting brace. Besides all of the above reasons, if a brace doesn't properly fit, you're less likely to wear it. When knee patients don't wear their braces, more injuries are likely. Surgical procedures don't heal up properly. The knee could actually end up in worse shape than it was before the injury or surgery. Insurance companies could even refuse to pay for your injury if they find out you're not wearing your brace. So, what do you do when a brace doesn't fit properly? Tell your doctor. A specially fitted brace may be required. You may require a smaller or larger size. He may decide on a different type of brace. Do not make changes for yourself. A qualified professional can find a brace that fits properly for your comfort.
