Your ITB needs to be released during femoral lengthening surgery in order to provide you with the safest lengthening and minimize complications.
The release of the ITB helps prevent the development of a wide-legged gait, which can be a significant issue if the band is not addressed. This gait abnormality is not only awkward but also challenging to recover from, potentially extending the rehabilitation period significantly. By releasing the ITB, the tension on the band is reduced, facilitating a more natural walking pattern and contributing to a smoother recovery process.
