CONTINUES TO HAVE PUSS IN THE WOUND. HAS HAD GRADTS THAT DID NOT WORK. ARE THERE INFECTION SPECIALIST FOR THIS TYPE OF PROBLEM.
[|AI|]  Hi, Welcome to Chat Doctor forum.  As you describe, your friend had a surgery on the knee, as result there was an infection, and it is not healing.  It appears that there might be resistant infection, or there may be some foreign body in the wound.  I advise you to consult a surgeon for diagnosis and treatment.  You may need to have culture and sensitivity of the discharge from the wound, and tests to exclude the diabetes.  Wishing for a quick and complete recovery. Thank you.
