After knee replacement surgery, it’s important for the woman and her family to know about certain things that would be warning signs of a possible problem. The woman goes home and she is having fever, she’s worried that her knee incision doesn’t look okay, maybe it’s little red or it’s draining. Then that could mean there’s a risk of infection. And I want that patient calling me so I can say, “Come back in so I can take a look at your knee.” Another thing it can happen is people can get blood clots, so we will send patient’s home on a blood thinner. But still if they get swelling in their knee after surgery that gets worst then we want to know that because maybe they could be developing a blood clot.
