Towards The End Of December, I Hit My Knee. It

Towards the end of December, I hit my knee. It swelled and bruised. I did have a little trouble walking but I kept it iced and kept it stable while I slept. Three months later, it still hurts a little when I touch it and on some days, my knee feels like a weight is there. I wanted to know if this sounds like a fracture or if the bruising just hasn't healed on the inside?
