Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

About fit

I have had several fittings done from two local shops, one of them was a video fit, I cannot recall...I want to say a "BG fit", but could be remembering wrong.
Every time I have someone do a fit recommendation I end up with pain in my knees. According to all the opinions of the people doing the fit, I am and have been riding with my seat too low. They keep trying to push my seat up to a point where it causes me this knee problem.

Now given, I have the one leg that is a different length and different form due to my prosthesis. We have done some cleat and toe adjustments on my leg in order to accomidate better form and comfort out on the road, but each time the guy keeps telling me to raise my seat.

So I have thought that if you are having pain something isn't right. My guy tells me that since I have been riding so long with my seat too low that it will take me several weeks if not months to get back to feeling right with the seat height. That in the end I will feel better and get more power.
The comfort zone that I keep going back to is within a couple of inches if not less than the seat post height where I get the pain. Is this something I should work though, and take the advice of the people I paid to give me a fit, or should I just go with what has been working?

I wonder if it might work for you some where in the middle.

How many inches do they want you to raise your seat? 4, more or less?

I'm wondering if raising it incrementally might help. Doing it all at once may require too much of an adjustment for your body to make suddenly.

I also wonder about your crank arm length. If it's too long you may be having to mash the pedals too hard. That could be tough on your knees.

Have you tried consulting a sports medicine doc? You didn't mention what type of prosthesis you have but if it causes one leg to be noticeably longer than the other (more than a few mm difference), I wondering if any seat adjustment will work. I'm guessing here, but if the difference in the length of the longest leg is more than a few mm, then maybe you might need to change one of the crankarms to make up the difference before you fine tune your saddle height.

^^^^
Good advice

I've never heard of this working or even being a good idea. Beware the internet. I've seen some pretty big differences being accomodated for with shims and stacking out a cleat.
