I don't know if this is relevant but here goes ......

I blew out my left knee playing soccer in 1983; complete tear in my ACL and 98% tear in my medial-colateral plus some other minor soft tissue damage. The surgeon who repaired my knee took a cold chisel and hammer to my paterllar tendon to strip off a bit. Two holes were drilled near the attaching points of my ACL and the bit of patellar tendon was threaded through and stapled into place. What was left of my old ACL was kind of wound around the new ACL.

I was in PT for ~1 year and was able to go back to playing soccer after ~18 months with a de-rotation brace. I lost a bit of lateral mobility but straight ahead speed was ok.

Techniques have improved drastically since 1983 so I don't think you'll end up with the 2 8" scars on either side of my knee. However your situation would depend on how badly you wrecked your knee. PT times may be reduced as well.
