I think first of you need to understand what problem are you having ?
If you are having internal knee damage, any of the treatment above- physio, chiro, acupuncture, tit tar, malay, indian medicine not gonna heal or cure the problem

In the end its just about managing it, understand the issue and know what to do and expect. If you are having a normal straightforward strain injury, seeing tit tar chiro or physio would do “miracles” you wouldn’t need to see orthopedic, but for you to see orthopedist means it has to be siginificant damage and he has nothing can be done may be referring to the internal damage.

Instead of bashing saying tit tar or physio or chiro or medicine or any treatment useless, you may say certain treatment useless first understand what problem you are having and start from there...
