Anne, it is hard to come up with questions about your "condition" - not knowing much about you, your issues and goals, except from our bonesmart forum. I can give you some EXAMPLES of what I would ask::
Is the scar tissue causing the issue? (have him draw a picture of the scar tissue - where it is in your knee) Why did it come on suddenly? Does the issue have a name (so you can google it for one reason)? If he says "no", I would ask if it is related to anything called "patella klunk" or "cyclops" syndrome? Is this issue common? How common? (percentile). How many of these have you seen or treated? (all OSs I have asked this question will answer it and gives me an idea of their experience in this) (Since the klunk is not common, it is possible, an OS may not have seen or treated it before)
What is the goal of the treatment plan to limit activity and use heat? - (e.g., stop the scar tissue from growing? limit its effect?) Why so many NSAIDS? (e.g., is there swelling? will the heat help the welling if there is any?) Are there other treatment options at this time? Why are we waiting for surgery if that is an option? Is there an advantage to waiting before surgery? Is there a chance the tissue would grow back? What are the potential results as well as complications of any surgical procedure? ETC... helps to organize questions by topic, going on to the next topic when I am satisfied
Besides a list of questions - I find the best approach (for me) is to bring a trusted person in with me. In this case, my husband. He knows what I will ask, and if I need a moment to think and ask the next question (as I get answers, I have more questions), he picks up and asks what he is thinking --- prevents OS from thinking we are done and walking out
I know my info here says I am from NH, but I did not have my surgery in NH
Keep up your courage - you WILL get past this - good luck
