Since the wires dont go through he muscles, at least from what i was told, the soft tissue will definitely recover from the pin sites. So you will heal just as much with an Ilizarov device as you would with a monorail device. It might take a bit longer though because of more pins.
With ilizarov ,
The wires are through the bone but over time during lengthen the skin starts to rip in snake lines. Ive got skin stuck to my bone still in places. Ive had a wire that pulled on my calf muscle and has caused a big dent in my calf. I had wires through my knees and come out through the back that has caused damage to my tendons in the back of my knee
I had wires through my ankles that have damaged the muscle and ankle tendons.
I had a wire through my muscle right in the middle of my leg at the front, think its called fascia muscle or something that has caused a rip in the muscle that has joined with scar tissue that is not flexible. scar tissue is not flexible like soft tissue, at times I can feel the scar tissue ripping even more.
The tendons in the back of my knee are not smooth now, they seem very rough and bobbled
