Likely re-tear of ACL (1.5 year post-op), odd mri results
« on: October 31, 2015, 04:36:36 AM »
26 male

I tore my acl and meniscus in september of 2013, did nothing.  Injured myself easily (1 foot fall from walking on a rope) 6 months later, got surgery in may 2014 using a nonirradiated allograft.  Was not aggressive with return to sports or PT ( only did 8 sessions over 1.5 months to get range of motion back).  Two nights ago, I tried some light soccer and felt+heard the mind-crushing crunch when trying to keep a ball from going out of bounds.  The motion which caused the damage was not extreme and would not even be strenuous to a healthy knee.

Got an MRI in the morning and saw some odd things:
the acl is fuzzy, implying a potential tear, the drill hole from surgery appears at full diameter, and the bioresorable screw appears to still be in place.

My questions:
What does the ACL look like to you?
Why does the drill hole still exist?
Did the bioresorable screw just not work?  Opposite effect?
Why is the bioresorable screw not yet dissolved?
Doc cleared me for light sports earlier this year, maybe something went wrong after then?
Any other comments?

ACL is torn. Most important failures of ACL are:

1) incorrect tunnel position (by far) and
2) failure to bio absorbe, cell ingrowth etc.

Based on the odds I would say your tunnels are likely to be placed incorrectly. I cannot see the attachment on the fibula but the one on the tibia seems to have the wrong angle. Too much vertical. But I am not a doc!! Scew takes about 2 years to absob. No clue why its still there. U need bonegrafting anyways.

Do a revision with a good doc. U need bonegrafting etc so dont go to a cheap place.
