The statute of limitations for medical malpractice in Pennsylvania is two years, meaning you have two years to file a lawsuit or your claim is barred. There are small exceptions in most states. For example, you might have more time to file suit if you didn't know the surgery went wrong until a year later. But if you knew right away (or should have known), then you may have missed the deadline. To be certain, call a local medical malpractice attorney.
