Had my left TKR yesterday. There was quite a bit of arthritis on the outside of my knee. To the point there was not much left except bone on bone. Also because my knee was putting more pressure on the inside, my medial ligament was stretched. Doctor put some stitches he's in to help secure it. So far, the pain has been managed well with meds. I have been up walking with walker a few times. My blood pressure has been lower than usual so they haven't let me walk today. Giving me fluids to raise it. If it stUs stable more pt then I can go home.
