I am so confused now. I really appreciate everyone's advise. But all 3 of the therapist in this office is saying opposite. Maybe I should talk to my doctor.
That's quite possibly due to them all being trained by the same source, or read the same book. I thought these thought went out many years ago, the world has moved on without them.
Nobody here is saying they shouldn't be helping you to bend your knee, but FORCING your knee to bend further than it is able is the issue. There IS a possibility of adhesions building up which would cause long term restrictions to bending. We do see this on here from time to time, but this seems to cause problems with only a very few who seem prone to this problem. If this does turn out to be a problem, then it is easily solved by forcing the knee to bend and breaking these adhesions ie an MUA (Manipulation under anaesthetic). That's an easy painfree successful process, normally carried out after about 3 months, if a problem actually exists.
The issue with your PT's is they seem to assume EVERYBODY will need it at some time, so do it to everybody WITHOUT anaesthetic, and at a stage before your knee has healed enough both to heal and probably form adhesions.
So what is being recommended on here is to allow the knee to heal, and only if adhesions are a problem, then do an MUA after healing has taken place.
It's the fact that they do it to everybody, regardless of need which is the issue.
I would talk to your doctor, and ask him to find a team of physiotherapists who have kept up to date.
