A hard lump has formed below my knee . I am 7 moths post ACL reconstructive surgery . I am getting a sharp pain around the bottom and outside of the knee when trying to fully extend. I am thinking that the lump my be fluid build up of some kind, and that i have just sprained the knee a bit. I am a builders labourer by trade and was back into work 9 weeks after surgery.
