Two hundred and forty-five knee dislocations were analyzed including
forty-one new cases. The high incidence of injuries to the popliteal artery
that accompanies this lesion (32 per cent) was confirmed, and it was
re-emphasized that vascular repair must be completed within six or at the
most eight hours from the time of injury to avoid amputation. Of the
patients not treated within that time period, 86 per cent had an amputation
and two-thirds of the remaining 14 per cent had ischemic changes.
