POSTER ABSTRACTS - ISAKOS

female and 13 male) of the eighteen patients
returned for subjective and objective evaluation
with use of two different knee rating scales at a
mean of twenty months after the operation.9
patients were in groupKDIIIL group and four in
KDIIIM group and five in KDIV group of injured
ligaments classification. With mean interval of 6
days (4 to 1 0 days), open surgical Treatment was
done. combined cruciate ligament surgery with
repair of the collateral ligaments was performed.
Results: The mean Lysholm score was 91 points
for the acutely reconstructed knees. The final
overall IKDC rating was nearly normal for one
knee, abnormal for nine, and severely abnormal
for six. No knee received a normal overall IKDC
rating. Of the knees with a severely abnormal
overall IKDC rating, received this rating because of
activity-related symptoms and flexion loss.
Patient subjective assessment( patients
satisfaction) was near normal in %70 of patients.
Mean knee flexion was 105 (60 - 135), Heterotopic
Ossification were seen in four patients in group
KDIV. Pseuduaneurysm of femoral artery was seen
in one patient after surgery.
Conclusions: Heterotopic Ossification is an
uncommon complication following Severe injury
to the knee and our study documents a trend
toward increased Heterotopic Ossification in
patients with group KDIV knee Dislocations.
Nearly all patients were able to perform daily
activities with few problems, but the ability of
patients to return to sports and strenuous manual
labor was less predictable.

A bicortical screw and washer is a commonly used
tibial fixation device in ACL reconstructive
surgery. This technique involves multiple steps
including bicortical drilling, depth gauge
measurement, tapping, and screw placement in
the proximal tibial metaphysis, each of which
have the potential to injure neurovascular
structures. The purpose of this study was to
compare the distance to neurovascular structures
between exit holes for screws drilled towards the
fibula in a medial to lateral orientation versus the
standard technique of drilling perpendicular to
the cortex of the proximal tibial metaphysis.
35 cadaveric knees were evaluated, 19 with the
drill hole directed posterior to the fibula
(posterior group) and 16 with the drill hole
directed at the fibula (fibula group). A bicortical
screw and washer was used for the tibial fixation
and the specimens were dissected and the major
neurovascular structures identified, including the
popliteal bifurcation, anterior tibial vein, anterior
tibial artery, common peroneal nerve, and the
tibial nerve. The screw exit site on the
posterolateral tibial cortex was determined and
using a fine caliper, the distances from the exit
hole to the neurovascular structures were
measured. An independent samples T-test was
used to compare the two groups with significance
set at p
