There is a lot of discussion on what is the success rate for flatfeet surgery. Needless to say there is no magic bullet for flatfeet. This is not a broken ankle where you just have to fix the fracture. Flatfeet can be caused by a myriad of issues so correcting all those issues in one operation can be very difficult. Again, the key to success of a flatfeet surgery is to have a surgeon who is well trained and thorough. Some Podiatrists will just half ass flatfeet surgery and this will lead to his failure rates.
Half ass you say? How does a Podiatrist half ass flatfeet surgery? Simple, they do something like offer you some implant like Hypocure, or BioPro or MBA. These implants are easy to do and almost never work, but the Podiatrist gets paid.
So the failure rate on implant surgery can range anywhere from 30-35%. It’s probably higher in my opinion. However, there are not many non sponsored studies on these implants to find the true failure rate.
Tendon transfer the failure rate is about 20%
Calcaneal Osteomies the failure rate runs 10-15%
Sometimes those operations are combined as well
Subtalar Fusions as well as Triple Arthrodesis Fusions the failure rate is about 10%
But remember, the key is finding a well trained surgeon. The more training and accomplished your surgeon is the better results you will find. So just be careful. Find testimonials, look up records, whatever you need to find.
