Thigh pain after knee replacement

Unfortunately, easy answers don't seem to exist. Almost certainly caused by the tourniquet during the operation, this nerve pain is truly excruciating isn't it!  Meralgia parestetica . . amazingly, it can also be caused by wearing too tight a belt!  Lyrica is often prescribed, but I didn't find it any help at all, although I do take Lyrica for the nerve problems in my feet following the operation, which I can obnly think were caused by the spinal injection.  I still have some numbness in the thigh, where the pain was, two years after the operation, but the pain is no loner around thank heavens. I really do not see any connection between weak quads and this incredible nerve pain, but perhaps there is. . . . I do hope it stops for you soon.  Mine started the day of the operation, but was not constant, usually waking me up at night and literally bringing me to the point of screaming. However, it didn't last more than a few weeks. . . . 

Thank you.  I don't buy the weak quads either - I'm too strong - my legs are like rocks from years of working out. I think they didn't want to open the door to any negligence.  I'm not looking for a lawsuit, just answers to explain the pain I never expected to have. Hopefully, in time, I'll be normal.  Right now I'm wishing I'd never had this operation.  I'm glad you are better and have less pain.

I think it is one of the complications which can happen . .and I doubt if there is really any negligence involved.  the amount of time, and the pressure of a tourniquet are crucial though, and recent studies I've read suggest that less pressure could be just as useful, and less damaging to the nerve.  this nerve runs from the spine, across the buttock, and down the thigh . . and this is where the pain tends to be. . although mostly in the thigh I think.  My surgeon didn't seem to know what it was. . or pretended not to . . but it was a neurologist who told me what it was.  Personally, Lyrica didn't do much for me, but for some people I believe it is helpful . . . I've never recovered the proper feeling in my thigh.  Even now, two years on, it is sort of numb to the light touch, but painful to pressure. However, not a real worry . . . Hope it soon improves for you.. . 

Good luck to both of us.

I had my original TKR in June of 2012 and am still in severe pain. In fact, it is getting worse. My surgeon also said he had no idea what the problem was. I have severe pain after sitting in a chair, car, or couch that puts pressure on the bottom of my thigh near my knee. I also have very limited range of motion. The range of motion keeps getting worse. I had a revision in December of 2014 and that helped for a while. Now it is worse than ever. The surgeon who did the second surgery wants to do another complete knee replacement. I am very hesitant to have one if they don't know what is wrong and how to fix it. 

I am six weeks out from a TKR and have the exact pain that you describe.  However, I have had to for the past six years.  Have been told I have a Baker's Cyst behind the knee which will go away as inflammation in the knee clears up.  Nothing helps the pain and it is definitely having an affect on my quality of life...unable to stand sitting in a car or driving for more than a short distance; cannot sit without my leg propped up, range of motion issues.  I have doubts that the knee replacement is going to be the solution.
