I've had two surgeries since the summer of last year on my ACL and I'm currently in recovery from the second surgery. Earlier this week I got my foot stuck in a hole in the pavement and my knee buckled. Ever since then, my knee has felt loose every now and then, and I'm not sure if I have yet again, got a torn / damaged ACL. My knee also hyperextends just a tad more than my other knee, although this isn't visably noticable. It's just a small amount but still, I can feel it move back just a tad further (I'm thinking this is what is causing the looseness within my knee). Also, my quad muscles are very weak because of two surgeries and not being able to recover completely. I know the quad helps with the stability of the knee, but I'm not sure if working out my quads will help eliminate the looseness and help control my knee.
So, does it sound like I have damaged my ACL again (I know I can get an MRI but I was looking for just some opinions), have I hyperextended my knee, and is minor hyperextension reverseable without the need of surgery?
Any thoughts?
