I think he is not specialist for nerves and tendons , he breaks bones or similar , i need if is possible in Europe same specialist for foot tendonds or nerves, Dr Halil only care for money i think and when issue happen he just move on to next customer, but now is to late i need to fix this with same pro clinic and doctors
Ballerina foot is one of the most common complications in LL surgery, so all LL surgeons must be able to handle it.
Normally, I would think that Halil should perform the surgery again, but if you cannot trust him anymore because he failed once, I understand your feelings well.
I'm not familiar with European doctors, but probably Giotikas would be able to handle it.
In addition to Achilles tendon lengthening surgery, there is a treatment method called Gastrocnemius Recession. I recommend consulting with a specialist about this option.
Also, since these surgeries are performed outside the field of LL as well, it might be a good idea to consult with a large orthopedic hospital nearby.
