Time in frames for 6-7cm of external lengthening?

Edit Post

I've been considering 6-7 cm of tibial lengthening with Dr. Leonid Solomin in late 2022/early 2023, and I was previously of doing LON, but I've since learned about the possibility of chronic knee pain doing that. So, I'm now thinking about pure externals. The question is, of course, how long do you have to stay in frames with pure externals? I've heard the rule of thumb that 1 cm of lengthening is equal to 1-1.5 months in the frames, but I want to know how accurate that is from people's experiences. Thank you.

Yeah, there’s just no way I’m going to sit in frames for 1+ years. I’d rather just do LON or internals if necessary.

Okay, so after a lot of research, I found a study looking at about 800 cosmetic leg lengthening patients, and the average was 42 days/cm detracted. That's fairly in-line with the 1-1.5 months per cm. Of course, LON/LATN is about a quarter of this.
