I was hit in knee area. Mild pain when pressure applied, but no bruising, swelling or any pain when walking. Could this be a growth plate fracture?

Most likely no. A fracture, including one around through or in the growth plate would normally cause very serious pain while standing and putting pressure on it and it would be difficult to walk, and swelling would normally accompany. Most likely a contusion, but see a doc if it does not get better after a few days.
