What Causes Pseudomonas Infection On The Wound Site Post Knee Meniscus Cartilage Transplant?

Question: Hi doctor,
my fiance had a knee meniscus cartilage transplant in Germany 6 weeks ago,.
Four weeks ago she discovered some pus + no fever and turned out to be psuedomonas infection,
Prescribed two antibiotics : (Teravid + averozolid) high daily doses for 28 days and the pus was gone. Now she finished her antibiotic course but found some dark liquid on her knee.
Please help, what could this be? How would this appear after a month of antibiotics? What should we do and what are the scenarios.
Thanks

Brief Answer:
Haematoma
Detailed Answer:
hi,
thanks for your question. the dark liquid which I presume is coming from
your wife's knee wounds could be old altered blood I.e. a Haematoma which is decompressing through the wound.
The worry would be that this may represent ongoing infection and so I would seek the input of your surgeon as further surgery to clean the knee or wound and antibiotics may be required.
best wishes

If its an infection, will there be any options other than surgery?
Brief Answer:
Yes There are options other than surgery
Detailed Answer:
thanks for the follow up question.
many infections can be treated with antibiotics only. if there is an abcess or collection of pus then this may need to be surgically drained and washed out. you said that you wife had a meniscal allograft. allograft tissue does not have a blood supply of its own and therefore it is difficult to cure an infection of an allograft. if the allograft is infected then this sometimes needs to be removed.

Brief Answer:
Follow up question answered
Detailed Answer:
hi thanks for the follow up question,
I presume she had the meniscal replacement because she was symptomatic in the knee joint.
her symptoms that she had preceding the surgery would therefore likely continue.
once the infection was adequately controlled then further surgery might by possible.
this is of course a hypothetical discussion as we do not know for sure that the allograft is infected.
