Sarah, Just wanted to say don't be too discouraged by the stories you read here. The people who have successful, pain-free results go on about their lives and aren't likely to post on a "Foot Problems" board. The majority of these surgeries are successful. Sometimes when you have foot problems, one thing can lead to another, causing long-term or multiple problems. Often subsequent pain is caused by waiting too long to have the surgery, or other things are stressed or damaged during the surgery and/or recovery process.
In my case, I had PTT surgery with tendon transfer and calcaneal osteotomy. During rehab my PT was overly aggressive and was trying to force my foot into normal inversion, which I will never have. Because I had waited so long and my foot was badly pronated my peroneal tendons were at risk already. In a perfect world they would have adapted to my newly realigned foot and all would have been well. As it turns out, I had a tear in both of them which occurred during PT. Would they have torn anyway? Possibly, but I'll never know that for sure.
Since I had peroneal surgery one year after PTT surgery I ended up not having a normally functioning foot for going on two years. This caused scar tissue to build up in the joint which made debridement surgery necessary. Scar tissue had damanged (or the multiple surgeries did it) my deep peroneal nerve which causes the pain I have today.
The foot is very complex and has many, many joints, ligaments and tendons which are made to work with each other. When one part is "off" it affects other parts of the foot. So I guess what I'm trying to say is that it isn't always that the surgery is not successful. Although I had two subsequent surgeries, my PTT surgery was successful. I've never had pain in the PTT area again. Had the series of events that happened to me not occurred I would be able to have a functioning, pain-free foot that. while not 100%, at least 75%, which is enough to do most anything you would want to do.
Don't worry too much.
Think positive, do everything your doctor tells you, follow up with a good PT and the odds are that you will be perfectly fine.
