What causes a lump that is movable inside the knee cap?
Patient: A couple years back and in 13 a plug went in to my knee but it wasn t to bad.it didn t go deep so I didn t go to the doctor my mom just pulled it out and over time it heeled but its a little lump that moves around in my knee it doesn t hurt anymore ....what is that lump moving in my knee cap??? Doctor: Hello there...May be it's a old collected blood due to trauma...Or may be a fat collection...Can be confirmed by simple investigation like ultrasonography...If it become painful or increasing in size may need treatment in form of simple excision...
