Best to ask Paley for a schedule.
But to give you a reference, my friend did approx 6.8cm at Paley for his femurs. He was walking without a cane by month 5.
But you can do the math. 1mm per day for femur = 25 days of lengthening. +1 month for consolidation. Assuming you are walking and putting pressure on your legs by standing up and moving around. I would guess you will be fine by month 3.
But to do both after 3 weeks to 1 month of you finishing your femur you will go under the knife again for the tibia. It’s .75mm per day so that’s approx 33 days for tibia. Tibia usually consolidates slower than femur.. but as long as you’re up and walking I think you can do it in 3 month.
You’re only doing 2.5cm.. that’s why my estimation is shorter than the other reply.
Month 1-2 would be femur, starting month 2 you will do tibia, so month 2-5 will be mainly tibia and some femur.
But honestly I can see you walking by month 6 without a cane. 2.5 isn’t a lot, and if you do PT everyday up till you discharge from Paley and you continue walking assisted, I can see you walking unassisted by month 6. Long distance walking? I don’t know, but I can see you walking short distances unassisted.
In terms of running, jumping and all that.. I don’t know.. that would up to your athletic ability before surgery, how well you recover, how much flexibility you retain, etc
