Question : Hi,
I had my 2nd Knee replacement on 1/3/2020. My 1st was done approx 5 years previously.
After my 2nd replacement, all was going well but something is incorrect. I just had xrays taken and the report is below.
I am worried I have to do it again? Thanks,
Will
CLINICAL HISTORY: Status post right knee replacement January 2020 with right
knee pain and swelling
--
IMPRESSION: Soft tissue swelling about the right knee prosthesis including what
is probably a joint effusion.
There is a 3 mm lucency between the lateral tibial plateau component and the
underlying bone for which infection must be excluded.
Minor degenerative change of the left knee.
COMMENT: Four views of both knees were performed.
Comparison is made to right knee films obtained immediately following knee
replacement dated 01/03/2020.
A right knee prosthesis is again noted. There is considerable soft tissue
swelling and ill-definition of the suprapatellar soft tissues suggesting a joint
effusion. There is a 3 mm radiolucent gap between the lateral tibial plateau
component and the underlying bone which was not clearly seen previously and is
worrisome for infection. Clinical correlation is advised. Three-phase bone
scan may be of further diagnostic value, as clinically indicated..
There are small spurs at the patellofemoral compartment of the left knee. The
left knee is otherwise unremarkable.

Detailed Answer:
Hi there
Thanks for the query
Do you have pain on walking?
According to the report provided, there is a chance of septic or aseptic loosening. You need to do the three-phase scan to look for infection.
Also blood tests with CRP will be helpful.
Knee joint fluid aspirate can be tested as well.
I hope I have answered your query.
I will be available to answer your follow up queries.
