Objective:
To summarize the research progress of killer turn in posterior cruciate ligament (PCL) reconstruction.
Methods:
The literature related to the killer turn in PCL reconstruction in recent years was searched and summarized.
Results:
The recent studies show that the killer turn is considered to be the most critical cause of graft relaxation after PCL reconstruction. In clinic, this effect can be reduced by changing the fixation mode of bone tunnel, changing the orientation of bone tunnel, squeezing screw fixation, retaining the remnant, and grinding the bone at the exit of bone tunnel. But there is still a lack of long-term follow-up.
Conclusion:
There are still a lot of controversies on the improved strategies of the killer turn. More detailed basic researches focusing on biomechanics to further explore the mechanism of the reconstructed graft abrasion are needed.
