I can only tell you that opinions in medicine change very slowly. I do remember that in the early days (pre 1990) there was no PT prescribed for any joint replacement. How and when it come into being, I have no idea but it seems to have got worse and worse over the years. I've worked at some prestigious hospitals during my career and while we probably weren't doing the number of joint replacements are now there was enough to know if the protocols they had were working our not. I never heard about this aggressive PT and these sayings such as the window of opportunity until I came on BoneSmart in 2007 and it really alarmed me. I asked around of surgeons I was working with and also from surgeons I met at the many medical conferences I attended. Not once did I hear any positive reactions to these issues. I also had relatives, friends and acquaintances who had hips and knees done and were not given any exercise routines to follow. Not one of them had problems as a result.
So I started advising people to not engage in anything that would cause them pain and what do you know - they got better and better! Had less swelling and pain and their ROM improved. I also had a number of members post that their ROM had improved months later and even as long as a year later. This body of opinion has just grown and grown over the years since and that's what I base my opinion on.
The importance of not allowing physical therapy or activity to reach a level that could be described as pain; and the difference between pain and discomfort.
Then it came time for me to have a knee replacement and wouldn't you know it, my surgeon told me not to do
any exercising for at least the first three weeks, just rest, elevate, ice and pain meds. (You really thought I made that up myself, perhaps?!) I found that after those three weeks I actually had pretty good ROM so I never did any at all and I never regretted it. When I had my second knee done, I deliberately did none and got an even better result which seemed to clinch it for me.
I was also encouraged by various members such as Celle who had done little or no exercise and still had very good results. Also of numerous members who had started out on the 'aggressive' path, ended up in great pain and distress and then, having followed my advice, found things change dramatically and they ultimately ended up with excellent results. The evidence on BoneSmart is staggering!
The "Window of Opportunity" constantly being used by surgeons and physical therapists as a weapon to beat us into submission.
Swelling and stiffness following joint replacement: how these factors affect recovery and therapy.
There is this article in the Scientific Articles section of the Library. These are all papers taken from peer reviewed medical journals. This one in particular address your concern

For me though, these are just a matter of common sense, summed up in the article
Swollen and stiff knee: what causes it?
Insufficient, poorly-designed, lack of a standard protocol in pain management following a joint replacement.
I can't think you would take this as being anything less than common sense either. Of course there are different types of pain and there are many ways of described them
1. soreness, burning, stabbing, throbbing, aching, swelling and stiffness
2. aching, tender, sharp, hot, burning, nagging, intense, stabbing, tingling, dull, throbbing (

3. Peripheral neuropathic pain is often described as "burning", "tingling", "electrical", "stabbing", or "pins and needles" (

I would add this - I belong to a University research group and a few weeks ago was discussing this with one of the professors. His immediate reaction was that this went again 'generations' of thinking and teaching. But he was also open to it and is right now considering applying for a research grant to do a study on it. I am very hopeful that this will come to pass.
Just to show I am not biased in this respect, I also posted this article in Scientific Articles in the Library
