Question: I have a 1/2" round free moving hard lump on the right side of my kneecap. It is not painful and can be moved around in about a 1" to 1 1/2" circle.

Thanks for posting your query.
I have gone through the picture of lump attached with your query.

Well, without a clinical evaluation it would be difficult to determine the cause of the lump. Possibilities that may need to be considered include enlarged bursa, lipomas, cysts, growths from underlying connective tissue etc.

Sometimes, a fluid filled structure just above the knee cap called supra patellar bursa is chronically inflamed, with or without pain, due to some infection or trauma and the process causes fibrosis and inflammation, making a lump like structure above the knee cap.

I would suggest getting this evaluated by an orthopedician for an accurate diagnosis and appropriate management. You may get the X-ray of the area affected and FNAC (fine needle aspiration cytology) of lump under his/her guidance.

Hope this answers your query. I will be glad to answer the follow up queries that you have.

Wishing you good health
Dr Saurabh Gupta

hi, out of the blue i had a burning aching sensation in my right knee. the patella was red and swollen with a swollen visible blue vein across it. it was hot to touch and tender. the swelling went down after about 10 min and the redness slowly disappeared. now a larger area over the patella is blue (on the right patella top left - if you were looking at my patella). it still hurts when i bend it as well. i have had tenderness in my right knee for a while that hurts when i do squats or sit at the desk all day with bent legs. any idea what it could be as i am really worried.
