Knee Bruise, Lump Under Knee. Surgery Done, Cartilage Removed, ACL Reconstructed. Treatment?

I had a surgery on my knee about two years ago. I had half of my cartilage removed, and my acl reconstructed using some of my hamstring tissue after a sports injury . I have been working my leg at the gym as I find since the surgery and even physiotherapy , it is always slightly weaker than my other leg. A bruise, that I believe just came out of no where has appeared on my knee scar. It is tender to the touch, and my knee is just a little ache out of the norm. But, nothing at all bad. It really only hurts when I touch it. But my main concern is not the bruise, but this little ball I can feel under it, now. Again, though, only when I touch and poke at it is it only slightly painful. Thank you.

I would recommend you to show to doctor who has operated you.I think what seems to you a swelling like a ball is screw head or sutures which is applied to hold the ligament. It can be some collection also. Your doctor will be able to explain you about that. As far as weak leg is concerned it is due to lack of physiotherapy and it will be there till you will not strengthen your muscles. You can take help from physiotherapist.
