I had Xarelto day 2 and day 3 after total knee replacement. Severe swelling began and Doctor stopped pills. After being home a few days swelling and redness became worse and I was put back in hospital to suction out blood amount size of football. Two days later Doctor drained off about 3-4 ounces of blood so I could go home. CPM machine was stopped also. I still have a lot of swelling and redness. Therapy is difficult. I had a very successful knee replacement 11 years ago on opposite knee
Hi thereXarelto is a blood thinner, prescribed to you after knee replacement to prevent you from making blood clots in your legs which could ultimately travel up to your lungs and kill. Complications of Carlo or any other blood thinner is bleeding. Swelling in the knee was caused by new bleeding in the knee, hence your doctor had to Chat Doctor.  This incident increases your risk of knee infection. If you are still worried that swelling is worse than I suggest you see your surgeon again as soon as you can since this time it could be an infection setting in.
