Tibia lengtheners - going down the stairs

Edit Post

Hey everyone.
Working on my recovery, I'm realizing that stepping down the stairs is pretty impossible.
Getting up the stairs is slow but possible.
Bending the knee for reaching up the stairs is slow but steady, however when stepping down, the pressure on the knee of the leg that's being bend (not the leg that reaches down the stair) is really hard.
Its pretty much the same movement as squatting. To a certain level it's not possible to bend further.
Is that common with tibia lengthening?
Would love to know about your experience

Nope. I did external only with ilizarov. No internal nail.
About 7 months post surgery and about 80 consolidated...
Trying to figure out if it's a problem or common weakness because of the procedure and lack of movement for a while....

Thanks.
Yeah it feels like you described.
I finished lengthening about 2 months ago and on x-ray seems like 60-70 percent of the gap is consolidated.
I also take into account that the pins of the ilizarov perhaps cause some limitations on the muscle around the knee or anterior tibia.
Physiotherapist recommended me to do exercises of Essentially squatting, trying to give it a try.

Just wanted to hear out other patients experience with this issue.

Thank you!!!
Reassuring messages here are extremely appreciated:)

I wasn't aware I should wait until full consolidation to push those muscles and knee. I actually feel pain and kinda push through it, thinking it might help on the long run, but maybe I will wait as you said..

The physio told me to do squat exercises that pretty much triggers the same pain / resistance on the knee.

Thanks a lot
