In vivo normal knee kinematics: is ethnicity or gender an influencing factor?

ABSTRACT:

Background

In vivo studies have suggested Caucasians achieve lower average knee flexion than non-Western populations. Some previous studies have also suggested gender may influence condylar AP translation and axial rotation, while others report an absence of such an influence.

Questions/purposes

We determined whether different ethnic and gender groups residing in the United States had different knee translations and rotations.

Methods

Three-dimensional knee rotations and translations were determined for 72 healthy subjects (24 Caucasian men, 24 Caucasian women, 13 Japanese men, 11 Japanese women) from full extension to maximum flexion using a fluoroscopic technique, under in vivo, weightbearing conditions.

Results

Although we observed substantial variability in
