Several months ago, I had the honor of tearing my Anterior Cruciate Ligament (ACL). It is an essential tendon that is in the center of all of our knees. The ACL helps with all daily movement. I was training Brazilian Jiu Jitsu one night. He caught me in a rough straight ankle lock. My knee made a popping noise. I felt intense pain in my knee. I yelped and I tapped immediately. It wasn’t immediately clear to me the severity of the injury. But over the next several practices it became clear that my knee had suffered an intense injury and match by match I was losing confidence in the joint.
