A lot of diaries have ambiguous endings under or around a year after lengthening. I've added the ones that stand out - clear positives, clear negatives, or outcomes that were at least updated signifantly after lengthening. There are so many diaries to read. This is probably 10% or so of them, if not less. Hopefully this is useful. Feel free to add others. If you're here & not happy with what I've said, I will add in your response.
Good outcomes:
ShyShy - Happy with result, no further surgery.
Medium Drink of Water - Happy with result, no further surgery.
badboy - Happy with result

Hannah84 - Happy with result
stillyoung - Happy with result
Lara - Happy with result
upinthesky - Happy with result

Neutral outcomes:
Smallguy - Required further corrective surgery but seems happy with the overall result.
Tdot - Decided to have further surgery
The_Rock - Happy with outcome, but running is ~70% of pre LL ability, explosiveness 40 - 50% (unacceptable in my opinion)
Growing - Happy with result, but has not recovered athletically after ~3 years.

Yellowspike - Continued height neurosis, looking at further surgery
prince2 - "Getting back to where I was before is impossible if you ask me. That will never happen. If I get back 70 % I would be very happy." despite this he seems satisfied.
OldieButGoldie - Unhappy with post LL functionality. Updated: I saw a post by OldiebutGoodie (see reply #99 in OldieButGoldie's Patient's Experience Topic) - he wasn't happy with my assessment. He didn't think the surgery was worth it, but had no complications and doesn't consider it a poor outcome

Other outcomes
mmm_native - multiple corrective surgeries & loss of function. Initially lengthened with an uknown doctor in Iran.
prince2 - 1.5 years post lengthening he still is not allowed (able?) to run, but seems to be happy & getting better.
andrewshizzles - He's an interesting one. He's able to run and move around OK. He runs a 30 minute 5k which is very very average but not awful, can shoot hoops OK etc. But he had a serious complication - his nail broke post recovery, his leg snapped in half and he had to fly half way around the world for emergency surgery.
