Well, only as a medical student in 1985, not as a patient. The Ortho doc I was with that month had been a former player for IU under Bobby Knight. He used other nearby tendons, or even cadaver tendons. Once it was an intact ACL tendon yet where the piece of bone had popped off and he was able to screw the boney piece back down to the tibial plateau and go back 4-6 weeks later and remove the screw and everything looked totally original again. He let me maneuver the arthroscopic instruments once and identify the anatomic landmarks on the video screen (no, didn't get to do anything fun). I'm sure there's been a lot of advancements over 35 years, but he was top notch in his field, doing stuff considered rare at that time.
