should the OS be pushing MUA's if someone is not in need
Definitely not! This is supposed to be a collaborative thing, not an autocratic declaration! I note many people are very scared of the idea yet when the surgeon 'suggests' it, they don't offer any protest or debate but just accept it because he is the 'expert' and must know best. (Not you, TexasTee!!) The truth of it is, if a person's flexion is not quite up to par at 6 weeks, there is still
heaps of time for it to improve before this needs to be done. However, if the flexion is about 70-80 at 10 weeks or more and/or there is a clear stop in the flexion which may indicate adhesions, then yes, it should be done.
does the physician have a responsibility to use caution as there is anesthesia involved
Of course! But it's a responsibility he shares with the anaesthetist who is, after all, the expert in the subject. But it's this concern and responsibility that calls for rigorous pre-op screening.
Also had a discussion recently over the difference between OS who do bilaterals versus one at a time....the person I was talking to felt that some OS want two bites of the apple so to speak and can charge for each operation and also some did it because the patients insurance would only pay for one surgery
Well I can tell you the inside story why some surgeons will do bilaterals and some won't - it's damned hard work! One TKR or THR is hard work but do a bilat and you're stuck in theatre for about 4 hours without a break. You see, it's not
just the surgery - the patient has to be positioned on the table, prepped, draped and then operated on. Once you start, you can't take a 'comfort' break or anything else! Very few other jobs are like that. Then the wound has to be sutured, a dressing applied and the patient seen off the table into recovery and the surgeon has to be part of all that because it's his job. When they do a bilat, both legs are prepped and draped one leg is done and finished and then the other. Some surgeons like to treat each leg as a completely separate operation with a new trolley of instruments and everything. This change over adds about 20-30 minutes to the whole procedure. It's worth pointing out that those who will do bilats tend to be quite a bit younger than those who prefer not to!
I don't think bilateral ops are so common over here
Don't you believe it! My surgeon does heaps as do his colleagues. and I can remember doing bilats way back in the 70s as well!
I guess there are minor risks any time one is put under anesthesia but do those risks increase the longer one is under? Same for the risk of infection. Is it better to be exposed twice for shorter periods of time than one, longer session?
Well yes, they do but if the patient is fit and healthy it's not too much of a risk. The wounds aren't open longer! The surgeon will do one, close and dress it, before he starts on the other one. However, if he has a colleague to do the other knee, they can work in concert so each knee is only open the usual amount of time.
Hope that clears things up a bit!
