Fascinating discussion from (so far) three nations! Great for insomniacs like me and nerds like you,
@L.I.T.! Haha. You sound like the type of nurse I like to get. Too few are compassionate these days and see patients as individuals, each with his or her specific needs. Certainly, a "one size fits all" system doesn't work in the long run, except financially. So maybe cost is a driver!
Since BoneSmart's nurse,
@Josephine, is U.K.-based, and she's firmly in the anti-"no pain, no gain" camp, maybe she can shed some light on why so many hospitals/institutions, surgeons and the physical therapy community are in such an all-fired hurry to get to 90 degrees.
Is it really all about rapidly-growing adhesions, as explained to me by PTs? In other ways, if you ask them, they appear to say that everyone heals differently, at his or her own pace. There certainly appears to be an anomaly.
Or maybe it is about quotas, keeping one's job by meeting certain criteria, and about moving sheep, um, I mean knees and hips, along the assembly line. Ethics, indeed! For the first time, the idea of a good, private hospital appeals to me as an individual. But I couldn't afford one!
