POSTER ABSTRACTS - ISAKOS

Sports Activity Scale scores. Education level (beta
= 0.34) and sports activity level (beta = 0.45)
predicted 32.9% of IKDC Subjective Knee
Evaluation Scores (P < 0.0001). Education level
(beta = 0.40), sports activity level (beta = 0.21),
and age group (beta = -0.27) predicted 22.2% of
IKDC Current Health Assessment Role Physical
subscores
(P < 0.0001). Education level (beta = 0.16) and
sports activity level (beta = 0.17) predicted 5% of
Role Emotional subscores (P = 0.019). Education
level (beta = 0.20) and sports activity level (beta =
0.25) predicted 10% of Social Function subscores
(P < 0.0001). Education level (beta = 0.28) and
sports activity level (0.30) predicted 16% of Bodily
Pain subscores (P < 0.0001). Education level
(beta = 0.23) and sports activity level (beta = 0.30)
predicted 14% of Vitality subscores. Education
level (beta = 0.25) and sports activity level (beta =
0.27) predicted 13.2% of General Health subscores
(P < 0.0001). Education level (beta = 0.21)
predicted 4% of Mental Health subscores (P =
0.01). Conclusions: With the exception of the
Role Physical subscore of the IKDC Current Health
Assessment, age group classification did not
influence these self-reported patient outcome
measures. Education level in combination with
continued participation in frequent training and
competitive sporting activities had a more
significant influence on self-reported patient
outcomes than age.

The Osseous Incorporation of Free Cancellous
Bone Cylinders in the Femoral Canal: A CT
Based Study According to ACL-Reconstruction

Purpose: A bungee- or windshield wiper effect in
the femoral canal in ACL reconstruction with
semitendinosus and gracilis tendon under usage
of various techniques has been described by
several authors. Additional impaction of free
cancellous bone cylinders in the femoral canal
was used in order to stop this effect.
Type of Study: A retrospective non randomized
study.
Methods: Twenty five male patients with an
isolated ACL deficiency were examined . All
patients were treated with a quadruple
semitendinosus and gracilis graft using femoral
Transfix fixation and additional impaction of a free
cancellous bone cylinder. The postoperative
reexamination was performed 8 ( 6 - 9 ) months
after the operation. At that point in time,
radiographs of the respective knee joint as well as
a Computerized Tomography (CT) were
conducted.
Results: Eighteen (72%) patients showed a
complete resorption of the cancellous bone
cylinder. The average tunnel width in this group
was 12.3 ( 11-15 ) mm. Seven (28%) patients
showed partially integrated cylinders. The average
tunnel width in this group was 10.5 (10-12 ) mm.
This difference was significant (p=0.003).
Noticeable was a missing correlation between
radiographs and CT-findings.
Conclusions: Additive cancellous bone cylinders
in the femoral canal did not fulfill the anticipated
function of preventing the bungee- or windshield
wiper effect respectively a stiffness increase.

Purpose: The aim of this study was to document
donor site problems one year after anterior
cruciate ligament (ACL) reconstruction and to
compare the differencies between hamstring and
patellar tendon autografts.
Materilas and Methods: Sixty-four patients
undergoing primary arthroscopically ACL
reconstruction were randomized to have a central
third bone patellar tendon bone (PT) autograft (30
patients) or a doubled semitendinosus/doubled
