    Total Knee Replacement issue
    Jerdav1 posted:
    I had my right knee replaced on July 7, 2011 in Mar of 2012 the knee "jumped the post" it came apart. I had to be anesthetized to put it back together. Four weeks later my doctor put in a larger post and told me that it would not happen again. Of course this required another surgery. Since the original surgery, I have heard and felt popping and clicking noises as I walk. My doctor says that they will go away, I am concerned that the noises represent a mis-alignment of the caps placed on the bones during the original surgery. The caps were not replaced during the second surgery. Is it possible that the mis-alignment caused my knee to "jump the post" and that putting in a longer post is not the best solution. Thanks for any help you can provide. I am concerned that it may come apart again.

    This is a tough situation. It is impossible to be perfect all the time your flexion gap. Trust your surgeon. Your flexion gap is bigger and with a longer post, the hope is that you don't dislocate it.

    Please tell me with such a major surgery as tkr, why wouldn't a doctor take the precaution of testing the patient for an allergy to the bone cement? I had tkr three years ago and have been in constant pain since. Discovered after metals and resin testing, I am allergic to three polymers in the bone cement. Now facing having the replacement removed and having to live with my knee being fused straight. Feel like I have been blindsided and can't face this. Also was told this can be a life-threatning complication - needs to be done sooner than later.
    Bal M Rajagopalan, MD responded:

    An allergy to bone cement is extremely rare. I have never seen a case like this myself. Being uncommon, it is not a routine to screen for cement or even metal allergies.

    I am allergic to the Actual bone cements A and B as well as to commercial extracts of 2-hydroxyethyl-methacrylate, ethyleneglycol-dimethacrylate, and 2-hydroxyethyl-dimethacrylate. It has caused both a local inflammatory reaction in the joint itself, along with a systemic contact dermatitis. I have been on Prednisone for 4 months and a topical Fluocinonide ointment . I have also had a fungal rash for 4 months , any who??? I have seen 2 orthopedic surgeons . one won't take it out because he has never done it before. Today I am having my second consult @ Hospital for Special Surgery . If you have ANY ADVICE, SUGGESTIONS , DR's names or numbers that could help me I would be forever in your debt ! Thank you !
