<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I had a reconstruction on my right knee in febuary last year, I recently noticed a hard lump at the incission point about the size of a 5-10 cent peice australian. Its sore to touch if I press around medially. Any ideas what this lump is? And how best to treat it?  <response>: Hi, Dear,Thanks for the query to Chat Doctor. I studied your query in depth. I feel concerned about it. In my opinion your hard lump at incision point is -keloid and or chronic cellulitis with abscess -at incision point of surgery done 1 yr back-as it hurts on touch. I would advise you to consult the knee surgeon who- would treat it with -antibiotics and NSAIDs with pus smear study-if its chronic cellulitis and or with Injection escort in multiple sittings-if Its proved to be keloid by -USGExcision biopsy. Hope you would recover fast with these health tips. Please contact again, and I would love to attend your queries promptly. Have a good time.
