1. Pain when kneeling on a hard surface, occasional discomfort when walking. Nothing at all when standing still.
2. None, really. I can still kneel.
3. 3-4 when kneeling on a hard surface, 1 occasionally when walking.
I get pain too when kneeling on hard surfaces and I
never had anything inserted into my knees. I also feel discomfort when walking for long periods of time, as well my feet ache (like normal people do)...All of these "issues" were
always there, even before my Femur lengthening.
I think most normal, healthy people, if they had to kneel or "walk on their knees" on a hard surface will get some type of pain or discomfort.
On a side note: I also receive discomfort when using my Elbows to crawl on a hard surface as well even though I never receive shoulder surgery.
That is why we cannot be so rash to form conclusions based on small sample sizes.
Hence, why, for example, in Japanese or Asian cultures where is kneeling is customary, people are aware of the discomfort of kneeling on hard surfaces and oftentimes use pillows, mats, or other cushions when kneeling to give comfort.

For example, I read many articles of people who
never underwent LL but still get knee pain for a variety of other reasons such as being overweight, being inactive, sports injuries, arthritis, diseases, Old Age and more.
I also read and personally witnessed people who were involved in traumatic injuries which required Metal rods; many of them had little to no issues whereas others complained about pain while being mobile and functioning in daily life. Whether that pain is because of their accident trauma or because of the IM Nail insertion is debatable.
I work in the medical field and see many cases of people who had IM Nail inserted through their knees and they are functioning 100% fine, lead an active life, and can do everything they usually do.
Also, I have personally witnessed other people who have never done LL still get knee pains even though there was no insertion trauma. Generally, they can barely stand for long periods and walk with pain. Some of these people cannot function in day to day life without pain or disability.
They have other issues which has caused knee pains such as being overweight, weak or unbalanced leg muscles, being inactive, unhealthy lifestyle, arthritis, diseases, from Old Age, and more.
This is a far cry from the "Superman" MDOW who can function in everyday life, and in his words,"feels stronger after my limb lengthening then before" and could lift more after his Limb lengthening then before it.
Finally, I have had the fortune to communicate with old patients who underwent Limb Lengthening with Rod Insertion (LON And LATN) and they have told me they experienced nothing negative longterm and fully recovered...even the Indian Doctor ones like sarin. Look at people like Smallguy, Captain America, or Calic.
So essentially saying, medical and biological responses are incredibly complex with many variables from a person's history, their bodies ability to heal, or many other countless variables so we cannot jump into rash final conclusions based on a very small sample size of a few active forum members.
Also, remember that the proper insertion of IM Nall for healthy patients who undergo Limb Lengthening in controlled way is different from the patients who experienced trauma, accidents or injuries and require emergency IM Nail insertion on top of their injuries and other variables.
Remember, correlation does not equal causation.
