What Causes The Knot Above The Knee After Hip Replacement?

Developed a knot above knee shortly after hip replacement. It seems to be bigger in the morning and I had thought it was a Lipoma. I ve had it right at 2 years and in recent months it has gotten to be consistently almost the size of a ping pong ball but just this past week I was put on blood pressure medication and it has completely disappeared.

Hello

I have studied your case.

Sudden appearance of lump/knot suggests possibility of infection.

Another possibility of autoimmune reaction leading to knot.

Clinical examination is essential to look for enlarged lymph node.
You may need to investigate in form of complete blood count, ESR, CRP, and if required fine needle aspiration cytology.

You may need to consult your doctor to confirm diagnosis.
Till time you can start medication and antibiotic consulting your treating doctor.

Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.

Take care
