Eighty-five cadaveric knees were measured with a stereotactic micrometer. Six cadaveric knees were studied using a 6-degree-of-freedom motion analysis system. Forty patient and 20 control knees were evaluated with CT. Three cadaveric knees evaluated by CT were sectioned into 0.1-1.0 mm slices, digitized and reconstructed in virtual space. The morphologic and biomechanical characteristics of the knee defined in these studies were imaged for presentation in 3-D and virtual reality.
The study showed that the sulcus of the trochlear groove lies lateral to the mid-plane and is oriented between the mechanical and anatomic axes of the femur. The femoral condyles closely approximate cylinders of differing radii that are oriented around a single flexion axis.
This study is the first to illustrate these observations in 3-D with virtual reality, according to the researchers: Donald G. Eckhoff, MD; Thomas F. Dwyer, MD; Joel M. Bach, PhD; Victor M. Spitzer, PhD; and Karl Reinig, PhD, all of the University of Colorado Health Science Center, Denver and Aurora, Colo.
