Chronic posterior cruciate ligament (PCL) injuries are
often affected by degeneration with symptoms including
thickening and elongation of the ligament. Conventional
diagnosis with MRI has proven variable therefore the
ability to quantify the shape of the ligament may prove
valuable. The purpose of the study was to characterize
the normal shape variations in an asymptomatic
population of PCLs using statistical shape models (SSM)
derived from MRI. We observed a significant difference
in absolute volumes between age and gender groups and
present the anatomical variability in a cohort of 27
asymptomatic PCLs analyzed using SSM.
