My DD had surgery at Children’s Hospital in Boston. Even within the orthopedic department at that hospital there is a split amongst the surgeons on the brace/no brace recommendations. My DD’s surgeon says wear the brace for the first year returning to play. Her teammate, who had surgery with a different Dr. at the same hospital said the brace isn’t needed once she is cleared to return to play.
To me, it’s like watching a Supreme Court split decision. All brilliant jurists, but there are differences of opinion.
