Sorry to hear that George
oh it happened years ago. July 25th, 2008 to be exact. Tore my ACL and partially tore a couple other ligaments in it. Was surgerically repaired by the same Doctor that did Carson Palmer's, Adrian Petersons and several other NFL and pro ball players. It's not been right since. Every now and again, it'll randomly catch and give up and when it did it yesterday I was walking thru the woods hunting so I ended up twisting it pretty severely. It's a ticking time bomb. When I had my surgery, doctor said due to severity, the likely hood I'd need another knee surgery within 7 years was over 70 percent. It's going on 10.
