it hasnt got anything to do with the surgeon just the company. if your paperwork says allegen you shouldnt have PIP. Take a look on transforms facebook page they have dates on there as to when PIP where used.
When you say the paper work do you mean the booklet that you get given after your op? If so you will not have PIP as this is the booklet that comes with each pair of implants and you should have all the details in the back ie which implant went on which side.
If you are still concerned give transform a call.
