The debate on whether getting to 100% of pre-op levels is even possible at all is a contentious one as there isn't statistical evidence to back it up, but I believe most people believe there is a trade off of athletic ability when considering limb lengthening alone from what we have seen.
Now, 100% with ATL is almost certainly impossible, nevermind with limb lengthening on top of that which we haven't come to a conclusion on. Logically it just cannot be the same as how it was before - the tendon will never have that elastic power again once lengthened. There have been peer reviewed studies and have been linked recently in the 'Body Builder' thread (crimson tide anecdotally went through ATL and has stated his 'push off power' is much weaker), the user Body Builder is now considering tendon shortening because of the weakness. He linked a study - showing the difference in power, muscular size, dorsiflexion etc. after an AT rupture even after tendon shortening -

'
The duplicate measurements showed a high intraobserver reliability (r = 0.90; P = 0.012). T test paired sampled statistics showed that the operated limb had a lower peak torque than the nonoperated leg (240.9 N ± 51.9 N vs. 299.0 N ± 44.2 N; P = 0.05), but the patients did not perceive this decrease in strength as interfering with their daily or leisure activities.' - So even if the person
believes they are 100%, they most likely aren't - and this is
without any lengthening which undoubtedly complicates things.
And after less than a minute of searching I found this -
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3178860/ which discusses how to deal with AT injury and avoiding lengthening because of the issues it causes.
'
- Tendon elongation correlates significantly with clinical outcome; lengthening is an important cause of morbidity and may produce permanent functional impairment.
- Furthermore, weakness in the end-range plantar flexion after AT repair recently has been attributed to an excessive tendon lengthening during muscle contraction.
- Moreover, increases in plantar flexor muscle cross sectional area, passive stiffness, and the ability to absorb passive energy also increase.
- Once tendon lengthening has become permanent, its clinical management is often difficult.'
Nevermind the likes of Paley advising patients to avoid it at all costs unless completely necessary.
I find it humorous how people can give anecdotal evidence and someone else can come along and say 'That's anecdotal evidence and is completely wrong, here is my own completely anecdotal evidence which is completely right!'. The issue on ATL isn't a personal one and putting forward the best evidence we have and discussing it civilly without resorting to insults would be better for all of us - even if the result of the surgery are less than satisfactory as we have to be honest about results.
