OBJECTIVES
To
determine the difference in shape of the distal femur, viewed axially
in two dimensions, between eburnated and non-eburnated femora.
METHODSA comparison
of 52 non-eburnated and 16 eburnated femora drawn from a large
archeological skeletal population. Eburnation was taken to indicate
late stage osteoarthritis. Shape variability, based on landmarks, was
quantified using a principal components analysis after a Procrustes alignment.
RESULTSA
statistically significant difference was found between the two groups.
This was with respect to the patellar groove and the shape of the
medial condyle. The latter difference is consistent with bone
remodelling as a knee stabilising mechanism.
CONCLUSIONSAnatomical
shape can be quantified using an uncomplicated statistical technique.
It was used to quantify the shape of the distal femur and demonstrate
shape differences associated with osteoarthritis of the knee.
