Torn ACL and Meniscus therapy at home?

I torn my ACL and my Meniscus September 19, 2007.I opted not to have the surgery because I wanted my knee to hea naturally without surgery. And i had heard that the knee would get really bad as time went on. But now I've lost the range of motion i used to have .. I guess due to scar tissue. I'm a very active person and I need this knee. Is there any exercises I could do at home to get my full range of motion back? I can handle a great deal of pain. And i need to have this all done by Friday! Please help!!!
