Cruciate ligament repair is repairing a torn or avulsed cruciate ligament at its two torn ends, rather than using a replacement graft.

- Type I - avulsion from the bone at the top of the notch
- Type II - tear through the substance of the ACL in the upper 1/3
- Type III - mid-substance tear
- Type IV - distal tear
- Type V - avulsion from distal tibia
The Sherman Classification is useful in determining which cruciate tears are most likely to be amenable to repair, Type I being the most likely to be successful.
Technique of cruciate repair
Cruciate repair had been abandoned some years ago in favour of cruciate reconstruction but, with improved understanding of which cruciate tears heal more readily and with improved technology, the procedure is making a comeback, especially in children where any harvested autograft would be too flimsy to use for a reconstruction and where the growth plates are still open and vulnerable to damage from drilling tunnels for a reconstruction.
"When considering suitability for primary repair it appears that femoral sided avulsions should be the initial focus...Significant caution is advised with mid-substance tears as significantly higher failure rates have been shown"
