hi,
my legs:
femur length: 335 mm
tibia length: 324 mm

femur +8cm photoshop example:

tibia +6cm photoshop example:

Which one do you think looks better?
(tibia 6cm or femur 8cm)

Didn't anyone look at the pictures? :(

The links aren't working dude,post them on a private album on imgur or something.

Tibias +6cm looks ok as you're tibias naturally look slightly short.

Thanks.
+2 cm so that the femur is not preferred for bad aesthetics.
-
or for +2 cm gain (femur):
to accept the bad aesthetic image

Well the femurs at 8cm don't look too bad I'm just worried about you using the LON method for femurs. But aesthetically I don't think you can ever go wrong with lengthening tibais

You're right.
Unfortunately, I don't have enough money for other methods except LON.
Is the femur too risky with the LON method? pain, health problems etc.

Well this forum generally advices against anything other than complete internals for femurs. I've not undergone this surgery yet ,so I can't truly comment on that but I trust the veterans here.
Still a 6cm increase in height is dramatic combine that with height increasing insoles and you'll definitely feel a lot better about yourself for sure.

Is it Not Bad for biomechanics to have such Long tibia to femur ? Should the Femur/ tibia Ratio Not be arround 0.8 ?

I don't know about this.
Is it better to have long femurs for biomechanics?
They say the femur is better than the long tibia like you said.
How is the ratio of femur and tibia calculated?
I founded this Medical research article.
https://www.ncbi.nlm.nih.gov/pubmed/26398436
BACKGROUND:
When individuals with asymmetric lower extremities present for evaluation of limb-length inequality, correction can occur at the tibia, femur, or in both bones; however, there are limited data available to justify either technique. The aim of this study is to examine the normal ratio of tibia length/femur length (T/F), and to explore the relationship between T/F ratio and osteoarthritis of the spine, hips, and knees.
METHODS:
Bone lengths of 1152 cadaveric femora and tibiae from the Hamann-Todd osteological collection were measured. Degenerative joint disease was graded in the hip, knee, and spine. Correlations between the ratio of T/F and osteoarthritis were evaluated with multiple regression analysis.
RESULTS:
The average ratio of T/F was 0.80±0.03. There was a strong correlation between age and arthritis at all sites, with standardized β ranging from 0.44 to 0.57 (P<0.0005 for all). There was a significant correlation between increasing T/F and hip arthritis (standardized β=0.08, P=0.006), and knee arthritis (standardized β=0.08, P=0.008).
DISCUSSION:
Increasing tibia length relative to femur length was found to be a significant predictor of ipsilateral hip and knee arthritis. Therefore, we recommend that when performing limb lengthening, surgical planning should lean toward recreating the normal ratio of 0.80. In circumstances where one bone is to be overlengthened relative to the other, bias should be toward overlengthening the femur. This same principle can be applied to limb-reduction surgery, where in certain circumstances, one may choose to preferentially shorten the tibia.
CLINICAL RELEVANCE:
This is the first study to report long-term consequences of lower extremity segment disproportion.
