You need to at least speak to one. You may be facing a statute of limitations bar to your complaint.

It is difficult to say based upon your description, but you should consider this. In order to prosecute a malpractice case you need another doctor to review all of the medical records and be willing to opine that your doctor deviated from the standard of care and that deviation caused you an injury. That become very expensive so the injury value must be high enough to warrant the expense. You should gather all of your records and meet with a lawyer to discuss your options.
If you can walk now you very likely do not have a case worth winning. It would cost an attorney $50,000 minimum and probably more than $75,000 to get the case to trial. If you win your damages would not cover the cost to get it to trial. Much of this type work is more art than science. Even if the doctor used the wrong size joint if another doctor says (and there will be 2 paid to do so) that joint used was a reasonable choice it is not malpractice.
