But there is good evidence for early manipulation. Here are 2 articles (which this board does not let me post the full link, I posted all but the first letter).

They conclude that early manipulation within 12 weeks of performing the TKA had a higher mean flexion gain (36.5°), higher final range of motion (ROM) (119°) and higher knee society score (89 points) compared to those performed after 12 weeks which were 17°, 95° and 84 points respectively. Other studies have also reinforced the idea that early manipulation within 12 weeks has a better outcome than those performed after 12 weeks.
And this:

Conclusions: Orthopaedic surgeons should have a low threshold for performing early manipulations with the patient under anesthesia within twelve weeks after an arthroplasty, to achieve higher knee range of motion and improved clinical outcomes.
There are lot's more studies with similar conclusions, some showing best benefits from even earlier manipulation.
I don't want to upset anyone but when I was reading these posts I felt I had to weigh in.
