Running after knee surgery

Is there a consensus on running and knee/joint damage? I had ACL reconstruction surgery in 2007 after tearing my ACL in high school. The dr used the patellar tendon graft method. There was minor meniscus involvement, but the dr decided during surgery that the meniscus was so minimally affected that nothing needed to be cleaned up. I did PT religiously and returned to play high school soccer about 4 months after surgery. The graft healed well and I've had it checked several times over the years with always good reports on stability.

I'm 30 now and am still pretty active. I lift weights regularly, run some (2-4 miles or sprints once or 2x/week) and ride a peloton 2-3x/week. My knee sometimes gets a little sore after running, but its never serious or inhibitive. My question is--would it be stupid to run more than a few miles a week if I want to maintain an active lifestyle as I get older? I currently run about 2-4 miles 1-2x per week. Is that potentially damaging? Would 10-15 miles/week put me at real risk of degenerative changes? I work a desk job and spend too much time inside. I like running because it lets me get outside and workout at the same time, but I don't want to be the dad who can't ski with his kids or teach them how to play sports because my knee is shot to hell with arthritic damage.
