Word of advice, it might be time to "hang up the gloves" on any intense sport. Not sure if you even partake... but knee ligament injuries seem to re-occur in many people, especially if the injury was the result of wear and tear. If it was a freak accident, then maybe not.
^^^ lol the words "outboard" and "bulletproof" don't belong in the same sentence. Unless the sentence is "I'm going to buy a new outboard motor so I hope my wallet is bulletproof!"
