Do knees braces and KT tape help knee recovery?

Knee braces can help after a knee injury. They are a temporising measure so they can help stabilise the knee if the ligaments have been injured in the short-term. In general, I don't recommend long-term use of a knee brace because it has a negative effect on the knee. It can cause stiffness and it can cause weakness of the muscles. Taping is very useful in certain situations. It can be helpful for patients suffering from pain around the front of the kneecap when they are returning to activity. But the taping should really be done by a trained physiotherapist.
