No, no imaging was done after the operation.
The knee is somewhat warm to the touch but not really red or discoloured.
OK Deirdre, We can continue after this if you'd like.
Two possibilities here--
One would be a large hematoma--blood collection from the warfarin he was on even if it were stopped before the surgery.
But the other more concerning possibility would be a septic joint--an infection,
I personally would get an MRI of the knee and consider a needle aspiration to see what kind of fluid is in there and to get it cultured since he may need antibiotics for this.
He needs to discuss this with his surgeon
Why would the swelling be getting firmer to the touch? The pain level doesn't seem to be decreasing. There's also a firm swelling behind the knee that I forgot to mention.
Any significan amount of fluid in the knee joint can cause a firm feeling to the swelling.
Also if there's a swelling behind the knee he may have a Baker's cyst back there, although I would assume that would have shown up on the pre-operative MRI
Can you please tell me if this is an urgent matter? It's now Tuesday afternoon and my husband's next appointment with his surgeon isn't until Friday lunchtime?
I'm most concerned, particularly as we specifically asked for imaging when we last saw the surgeon (yesterday morning), but he said he didn't think it was necessary. He did mention the possibility of a hospital admission for IV administration of antibiotics, but as we're paying for all of this privately out of our own pocket (to avoid the 18-month waiting time for surgery), we're rather scared of further costs!
Thank you for your helpful responses so far. I think we're nearly there now.
I've just taken my husband's temperature and find it slightly raised from his normal, which is 36.2. At the moment it's registering as 37.6c. At what point should we be alarmed? As things stand, we're just a bit concerned.
