What is the difference between TTT, lateral release, and knee reallignment? I am getting diagnostic arthroscopy and chondroplasty on friday. The doc says that after they have a clearer idea of what is wrong they will know type of surgery if any will be needed next. He says it will probably be a knee reallignment. My physical therapists is betting it will be a lateral release. Then someone else said that TTT is the same as a knee reallignment. I am so confused. Can someone clear anythign up for me? :-/
