Abstract
37 patients who had undergone PCL reconstruction between 2009 and 2014 were included. A standard follow-up was performed for at least two years and consisted of pre- and post-op Lysholm scores. Lateral knee radiographs were studied and the measurements of the tibial Plateau to tibial Tunnel Length (PTL) and superior tip of Fibula to tibial Tunnel Length (FTL) were collected. A correlation was then derived and illustrated via scatter plots.
Highlights
The posterior cruciate ligament (PCL) is not as well studied as the anterior cruciate ligament (ACL) because the incidence of acute PCL injuries is low at 3.4% to 20% of all knee injuries ([1] as cited in [2])
We report our finding of a correlation between position of tibial tunnel with respect to superior tip of fibula, and clinical outcomes for PCL reconstruction
Our data suggests that better clinical outcomes are achieved when the tibial tunnel exit point is closer to the superior tip of the fibula
Summary
The posterior cruciate ligament (PCL) is not as well studied as the anterior cruciate ligament (ACL) because the incidence of acute PCL injuries is low at 3.4% to 20% of all knee injuries ([1] as cited in [2]). This leads to many differing views towards its management [3,4]. Most of the studies take the posterior slope of the tibial plateau or the joint line as a reference for the PCL exit point, we are the first to have taken the superior tip of the fibula as our reference point for tibial exit of PCL
