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.
An MCL tear is where the medial collateral ligament on the inner side of the knee gets overstretched and damaged. It is most commonly caused by a sudden twisting force through the knee, which damages some or all the fibres of the ligament. It can lead to swelling, pain and instability.
