Hi, I am 5 years post total knee - Zero problems for 5 years, the all of a sudden it started swelling for no apparent reason - I'm active and play lots of pickleball (very competitive!!). My 2nd time back to the Dr and he drained it - it was all blood. he suggested conservative activity, some PT etc... I continued to have swelling, and he drained it again, and again it was all blood. He at that point suggested Genicular Artery Embolization (GAE). Its a procedure that an Interventional Radiologist performs - its considered minimally invasive. It was developed for excessive bleeding in patients with TKR, (its also being used pre TKR for pain relief to avoid having a TKR). I've had my knee drained 2 more times; one of them was extremely painful - I couldn't bear any weight on my knee, I called the office and said, i'm either coming to you or going to the ER; they had someone available to drain it (more than 130cc's of blood). Anyhow, I am scheduled for the GAE tomorrow morning! I've been miserable not being able to do any activity whatsoever now for over 2 months; I have yet to know what movement is causing my bleeding. It may take me a few days, but I'll post back here to let you know how it goes; although it will be a week or so before I can test it to see if it was successful...
