I actually visited this center in turkey to see the patients.
Most (all) of them seem satisfied.
Most of them seem pretty miserable walking with fixators and crutches, but - thats how it is no matter where you do it.
The rate of infection is low, and even that (infections) is a risk and a very very common obstacle that happens in the hand of the most skilled surgeons. In fact it doesn't have to do with surgeon's operation. Unless the infection was presented during surgery which causes deep infection soon after surgery, this complication I didn't encounter.
The facility and environment of a bunch of patients going through the experience together is something I can almost for sure say, that is highly motivating and comforting.
Practically, the only negative feedback from patients I got there was "don't do LON" (femur) which is mostly because of extreme discomfort, lack of ability to sleep, shower and find ease and rest. This is also obvious and not related to the center of the surgeon, it's just a hard process. They also said it since patients with precice nail was having a much easier time, making the Lon patients kinda jealous, I think.
But there are thing no one can deny, the amount of surgeries they do is huge. Having a doc who is so much experienced doing the same surgery over and over again, and a team treating the patient in aftercare, and amount of patients walking out with a smile.... All of this is enough for me to assume they are not nearly as bad as this forum claim.
Quadrilateral lengthening is risky and to me seems like a bad idea, no matter where you do it.
