Why don't they have a small camera on the end of a needle?
« on: August 16, 2009, 10:20:32 PM »
It costs thousands of dollar to simply get an arthroscopy, so why can't they make a very small camera on the end of a needle that a doctor can just stick into the knee to take a look? The needles they use to drain the knee are fairly wide anyway. This would be good to check a specific area to see how much cartilage damage there is or to follow up a few months after surgery.

Anyone have any thoughts on this?  ???

Isn't arthroscopy a very small camera that lets the doctor take a look in the knee?

Yes, but they still need to make incisions and it costs thousands of dollars because they need to use anesthesia and so forth. I'm asking why they can't make an even smaller camera that can be inserted in the need like they insert a needle to drain fluid in a doctor's office. It wouldn't have to look at the whole inside of the knee. I'm thinking like if there is one particular area of cartilage that had microfracture done on it and they want to follow up and see just that area. Stick the needle in, look at that one area and take it out. No risk of infection or major procedure like an arthroscopy. MRI's don't show the detail like an actual camera would. Maybe they already have something like this but I never heard of it.  ???

I'm sure they will have something like that eventually. They used to have to cut your knee wide open for everything, now they use a really small incision with the arthoscope. I'm sure that they continue to look for ways to make surgery as little invasive as possible. At this point it may cost too much to make a camera that small and still retain a clear picture. Engineers will probably have something better coming up, every year there are lots of medical advances.

I know that, I'm having my third scope in a couple months.

I think the problem with a needle is that it is rigid, and so would have a really limited range.

It would be good if there was such a system for a knee situation like mine as my MRI scan came up normal and tried physio, ultrasound and cortisone injection and all failed so the only option left is to scope the knee. Not looking forward to it for 2 reason my OS does not know whats wrong inside the knee and the general anesthesia, be good if it was that easy to stick a needle inside the knee so OS can see whats going on as you could return to work the same day without too much discomfort. If the OS then finds the problem he can then scope the knee and know's what he looking for.

My main concern about my scope due in october is if he finds nothing wrong inside the knee would then have to recover and have time off work for nothing and waste the NHS money. The knee would then be more prone to arthritus and scar tissue damage which can happen if you have your knee scoped.

I can see some logic in John's idea and who knows one day it may be available and could save time and money on unnecessary scopes. I agree that MRI scan are not always reliable and untrasound is even worse which they also tried out on my knee to spot any potential problems.

Thanks for the replies. Maybe part of the problem is the knee fluid isn't clear so a camera wouldn't be able to see clearly. In an arthroscopy, they pump a clear fluid (water?) into the knee to make things crystal clear. But even still, maybe they could come up with a camera on a needle that can see through the unclear knee fluid.
