POSTER ABSTRACTS - ISAKOS

5.3±2.1 in the ACL-injured side, being significant.
Proprioceptive examination clearly showed poor
joint position sense in the ACL-deficient knees
than normal knees. On the other hand, the
healthy side had a significant better ability for
both OLH and OLV. The performance of ACLdeficient
knee was also worse than healthy side.
In addition, a minus correlation with a significant
difference was found between proprioceptive test
and functional ability, and this correlation was
emphasized at visual deprivation.
Conclusions: Deteriorated proprioception in the
patients with the ACL-deficiency reduced the
patient’s functional ability.

In ACL reconstruction using 2-bundle hamstring
tendons, initial graft tension is controversial. The
purpose of this study was to examine second look
arthroscopic findings after ACL reconstructions
done with different initial graft tensions (60N or
100N).
Fifty patients (24 males, 26 females) underwent
arthroscopically assisted ACL reconstruction. The
patients were divided into 2 groups (group A :
initial graft tension of 100N ,and Group B: tension
of 60 N. Group A (100N) contained 6 males and 14
females. Group B (60N) contained 18 males and
12 females.
With regard to arthroscopic findings, synovium
coverage of the reconstructed ACL wsa
categorized into 3 grades (Good, Fair and Poor),
differentiation of AM/PL bundle was categorized
into 2 grades (Separation and Union), tension of
the reconstructed ACL was categorized into 3
grades (Good, Fair and Poor).
With regard to anterior tibial translation, there
was no statistically significant difference between
the two groups, but there was a greater tendency
towards good synovium coverage of reconstructed
ACL in the 60N group than in the 100N group, as
well as good tension and union of the AM/PL
bundle.

Introduction: Anterior cruciate ligament (ACL) is
collection of fibers which are divided into
anteromedial and posterolateral bundles.
Recently ACL reconstruction using double bundle
of graft or two tunnels at femur were introduced in
order to recruit as many fibers in ACL insertion
area as possible so that rotational instability can
be overcome. We introduce novel technique using
Achilles tendon allograft with which triple bundle
can be placed in the knee.
Methods: 58 patients who were undertaken triple
bundle technique were followed up at least one
year, were included in the present study. The
results were assessed by physical examination,
functional score (Lysholm’s score, international
knee documentation committee knee subjective
examination) and objective joint displacement
evaluation (KT-2000 knee ligament arthrometer).
Results: The results of the Lachman, anterior
drawer and pivot shift tests were at least grade I
instability. Average of Lysholm's score was
increased from 63.7±8.3 to 87.7±7.1 and 41 cases
(70.6%) were normal and 17 cases(29.4%) were
nearly normal according to the IKDC examination.
Using KT-2000 knee ligament arthrometer, average
of preoperative and last follow up joint
displacement was decreased from 15.8±2.12mm
to 8.2±1.90mm in 30 degree flextion of the knee.
All patients returned to the normal activities of
daily living.
Conclusion: The intra-articular triple bundles
technique is considered to be useful ACL
reconstruction.
