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
