Of the three main etiological factors which
may give rise to Dislocation of the Knee, viz: - Congenital abnormalities,
I intend to limit myself to that of "Traumatism,"
which, although rare, is, in modern practice,
probably more frequently met with than either of the
With regard to Traumatic Dislocation itself,
the literature on the subject is not very extensive,
only some 114 cases having been collected by Stimson in 1901. Since his work appeared, I have been
able to obtain particulars of five other cases in
addition to the three which came under my own observation during the period I acted as House Surgeon
at the David Lewis Northern Hospital, Liverpool.
So far as I have been able to ascertain, no
previous research has been conducted upon this
particular subject. That little I have been enabled to carry out is by no means complete, a misfortune due entirely to the véry great difficulties
experienced in endeavouring to obtain material upon
which to work.
I have been enabled to experiment upon six
bodies in all, and the results of this work will
be indicated in detail at a later stage.
During the process of dissection, careful notes
were made, not only of the position and relations
of the structures which were displayed upon the
photographic plate, but also of the various structures which, from their anatomical situation, were
unable to be represented owing to their deep seated
aid therefore concealed position. These notes will
be considered in detail when the different forms of
dislocation are studied seriatim.
