Hi Bryan. I had something similar to your injury. It is called a tibia spine avulsion, instead of the ACL tearing, the bone snapped. I am 3 weeks post accident (fell 30 feet while climbing on July 13 and had to be choppered out), and in a leg brace with a range of motion limited to 30 degrees. It sounds like your doctor opted for a restrictive treatment. I had my CT scan on August and I find out more next week. I don’t have too much pain and find that I am able to bend my leg to 90 degrees with little pain.
Everyone is sure different- Hang in there!
