I had TKR last September and have been having issues since then, even before then. I have a hematoma on the right side of that knee that was there before my surgery. I was hoping the surgery would fix it because I was told by multiple surgeons, it's there because of the bad knee. I had the surgery and the hematoma is worse then ever and hindering my recovery. I spoke to my surgeon about it and he said its caused by a tendon that has partially detached. I have three treatment methods I could go with, two of which won't work. 1. Get the hematoma drained. I've gotten it drained twice and each time it filled up within a week. Also risking infection every time they stick a needle in the knee. 2. Wait and see if the fluid reabsorbs. I've had this for a couple of years and it's just getting bigger. 3. Surgery to reattach the tendon. This is my only option BUT my surgeon said it's a 50/50 . Because there is so much damage already done to the tendon he said it may detach again. I need this fixed because I am in so much pain and I'm afraid it's going to affect my new knee. My whole body hurts because I'm not walking right and its throwing my spine out of alignment. Does anyone have any advice?
