Thanks for writing to us.
After a knee replacement surgery, the cement of the knee joint may not work sometimes making the joint loose and unstable. This needs a direct examination to the extent of loosening and further management.
I hope this information has been both informative and helpful for you.

Hi, thanks for writing to HCM.
Generally, loosening of the components after total knee replacement could be due to two causes
* Aseptic loosening (without infection) - this usually will not occur so early, as in your case within 2-3 years
* Septic loosening ( due to infection) - this can occur as early as 6 months after the surgery. And I suspect this in your case.
Strictly speaking , any early loosening of the implants should be adequately evaluated for the cause. If a revision knee replacement is performed, then it is going to fail inevitably (as in your case).
So i suggest you to approach a surgeon who has got good experience in "revision total knee replacements" and follow his advice accordingly .
Hope this helps
