Damn! Where did the bike land on you at? The recent accident? See, us simple folk don't know all those technical terms like ACL. Unless it clocked you in your American Civil Liberty
The bike wasn't the real source of injury... landing on the concrete floor was! I tried to break my fall by landing on one foot, but the force was overbearing and the knee joint tore laterally. Better that than breaking a hip, which I envisioned as I fell. Read more on knee injuries.
