My doctor did an allograft and autograft (hamstring) to repair my ACL. He says in his experience it makes for a stronger tendon, with a lower rehab time. I am now 11 days out of surgery and have 110+ degrees of bend and full extension. I've been off crutches for 7 days now and have nothing on my leg but an ace bandage to cover the bloody scar tape. I can go upstairs fine and walk only with a little limp. I had a complete tear of my ACL back in May from a soccer game.
