The Statute of Limitation in Michigan is two years from incident or 6 months after discovering the malpractice. It sounds like the knee hasn't been right since 09 so my initial thought is no but I would consult an attorney with all the facts.

If the malpractice took place in Michigan, you generally have two years from the date of the wrongdoing to commence a claim. There are a few narrow exceptions to this rule. For example, if there is no way you could have known you had a potential claim or if the doctor intentionally concealed important information from you. If your husband had a legal disability - in other words, unable to understand for himself that he could have a potential claim - you might have more time to pursue a claim. As you can see, Michigan medical malpractice law is very complicated and I would encourage you to speak to an attorney about this issue.
