[|Human|] My mom has fallen on her knee and it swells with activity and is very sore to walk on. The swelling is just below the knee cap (We believe). The bump is roughly the size of a half dollar. Should we see a doctor? Has she fractured anything possibly?
[|AI|]  Hello, Injuries to knee are either of the bone or of the surrounding ligaments or a combination of them. Anything intra-articular would present as swelling of whole of the knee and not only a part of it. You need to get an x-ray done, which will be diagnostic, if not proven, so you have to wait with conservative management till the time swelling subsides, and at that time. If the symptoms persists you have to go for a MRI. Till that time you need to give rest and support to the knee with the help of a brace and do cold fomentation until the pain and swelling subsides. Hope I have answered your query. Let me know if I can assist you further. Take care
