There is no fixed amount of time it will take to have your braces removed. One thing you can be sure of though, is that it will be much quicker than when you had them attached. Expect to be in there for around an hour for all the braces to be taken off and all the follow-up work to be done.
Twisting the knee is a common cause of overstretched or torn ligaments of the knee. The knee may give out suddenly when the ACL is torn and there may be a popping sound upon injury. Symptoms of a torn ACL include knee pain, swelling, stiffness, and bruising.
By far the most common cause of medial collateral ligament sprain is a blow or sudden impact to the outside (lateral) of the knee joint. This causes the outside of the knee to collapse inward toward the midline of the body and the inside of the knee (where the medial collateral ligament is located) to widen and open up. This opening up stretches the ligament, which results in the injury.
