15 days post op

Went to work today, I'm a cop so I'm on light duty right now sitting at a desk doing basically nothing. I went to PT, my PT said that the swelling could be because I've been working it hard, he said not to worry about that swelling would go away and come back throughout the process. Did all my normal exercises today but the PT added a new one to help with my extension. PT had me sit down and put my leg on a chair in front of me he then put 12 pounds of weight sleeves (kinda like those ankle weights that you wrap around your ankles when running) on my knee and left me for 12 minutes. It was very uncomfortable but afterward I had more extension ill definitely continue this exercise at home. Hopefully walking will come next.
