It's not that Drs are lying to us, it probably the fact the were are a small proportion of PFS sufferes and the mjority of whom have had bad experiences, but there is some success. myself being one of them.
Yes some people will need surgery and yes some will respond to PT, it varies so much perosn to person, I don't think it is fair to make judgements based on what is said here, we all suffer from knee pain and for some of us, it won't be attributed to PFS but to something else.
Basically, every perosn on the earth is an individual and they will respond differently to treatments that are offered. You may also find if you ask around on the board that some ppl's surgeons are too surgery happy and that is why they have had surgery.
