Ellen’s , I had the tourniquet and block also .I am six and a half mos.post TKR .I don’t think it’s that. I’ve done all the reading I can on I T Band and I really believe it’s tension on the ITBand which is a ligament running from hip to beyond the knee.I don’t like foam rollers but do recommended stretching esp. for the quadriceps. I have also found biking in a lower gear helps .I do 7-8 Miles ,flat surface. I think it’s getting better. At night I put 1% diclofenac
gel liberally on my knee.Then wrap it in Saran Wrap and put an ace bandage around that.
In the AM it feels great which tells me it’s probably still inflammation. I do a few quads strengthening exercises too . I think as time goes on and ALL swelling resolves we’ll get better. Lot’s of articles on IT Band post TKR
surgery. Good Luck. Ralph
