Hi,
thank you for providing the brief history of you.
As mentioned by you that post TKR you are having swelling and
redness in the operated knee. CPM is stopped. And the fluid was also drained.
Now to help you further, you have undergoing 11 years ago a TKR which was successful as your age was the matter. Now 11 years later you are 11 years older than the first TKR. So there will be a lot of degenerative changes in the body and muscular system. To start with, The CPM at this stage will be a painful process for the and the internal muscular
injury will be possible.
So stopping the CPM is a good choice. Now since you are at home, i will advice you to take quick icing technique which a physical therapist will help you for it. As quick icing helps to reduce the swelling by providing the quick
muscle contraction. Performing static quadriceps and static
hamstring, though it will be painful but will surely help to make the TKR successful once again. Also, by performing SLR the drain of the swelling is possible and the optimum recovery is achieved.
In my personal practice i have seen cases with similar complaints and they are helped better with
physical therapy even in the painful state. A 99% recovery is achieved in most of my cases and expect the same from you.
A strong will power will surely help you to come out of this situation.
