Leg lengthening without physiotherapy for the tibia

Edit Post

Is it compulsory to do stretching exercises when lengthening your legs? Are there alternatives such as lengthening the muscles with medication instead of physiotherapy? Then you could go home more quickly instead of waiting in the hospital for months.
I've researched and haven't heard anything about whether such an alternative will be available in the near future.

Thank you for the answer.
I mean during the extension process not before. Because of the stretching exercises I would have to live in another city for 2 months and I also think if the muscles, tendons and nerves could be lengthened with medication, you would have the chance of lengthening them by more than 1 mm per day.
If such experiments are currently being researched, I would wait another 5-6 years to carry out the operation.
