I gave you an instance about the specific remark you referenced. MDOW underwent extensive limb lengthening on his tibias (approximately 8CM) and encountered a complication (possibly tarsal tunnel, though uncertain) that still troubles him many years afterwards. He expressed regret for not opting for a lesser increase. Another issue is the development of ballerina foot. An increase of 8CM on your tibias is significant. This amount closely aligns with the recommended limit for femur lengthening.
