POSTER ABSTRACTS - ISAKOS

had been included in the inclusion criteria.
Conclusions: the average of age was 27,8 years. 15
lesions were on the right side. 23 patients had
ACL injury were sports related. Only 4 patients did
not perfom any sports daily. 18 patients had
associated injuries. 9 were medial meniscus tears.
The patellar tendon graft was used in 22 patients
and 6 ACL injuries received hamstrings grafts. 22
patients concluded their treatment without any
major complications. 3 developed patelar
tendinitis and 1 patellar fracture was reported.
With the IKDC evaluation protocol, 18 patients
had B grade and only 2 achieved C grade.

Introduction: The anterior cruciate ligament (ACL)
is crucial for the knee stability. Its injury is one of
the main causes of sports related injuries,
propitiating instability and increased risk of
meniscal and condral injury. However, its
evidence in the feminine sex seems not to present
only an unique etiology. Objective: To focus the
etiopathogenic aspects of ACL injury in women.
Material and Method: An electronic research in
the virtual library of our institution was carried
through, through specific solicitors. They had
been boarded articles related to the injury of LCA
in women. Results: The authors had found 45
articles pertinent. 37 articles in english language
had been selected. Conclusions: The more
prevalent risk factors can be divided in hormone
related, anatomical and ambient or extrinsic
factors. The estrogen, the progesterone and the
relaxina have influence in the ligamental
looseness. Wide pelvis, a lesser muscular
development of the thigh, increased flexibility and
the hiper-extension, the geno valgus, the femoral
anteversion, the narrower intercondilar notch and
the external rotation of the tibia had been the
anatomical aspects more frequently related to the
etiology of the LCA injury. The sport more
frequently related to the injury of LCA in women
was basketball. The quality of the sports
equipment, as well as the type and the conditions
of the field are important extrinsic aspects to be
considered. The prevention must be prioritized to
minimize the genesis of ACL in women.

INTRODUCTION:
Closed kinetic chain exercise is reported to be
quite safe for anterior cruciate ligament (ACL)
deficient knee due not to be presumably less
anterior translation of tibia than isokinetic open
kinetic chain (OKC) exercise because cocontractions
of extensor and flexor muscles
around the knee joint to be stabilized. The
objective of this study was to make a new device
for isokinetic CKC exercise and to evaluate the
usefulness of CKC muscle exercise in comparison
with that of isokinetic OKC exercise to be
established the safe rehabilitation in ACL
deficient knees.
PATIENTS AND METHODS:
We evaluated the 8 ACL deficient patients (2 men
and 6 women, mean age 22.1±11.6 year) about the
muscle strength around the knee with two
isokinetic exercises. One was isokinetic OKC with
CYBEX NORM (Lumex, USA) to assess the muscle
strength of knee flexor and extensor in both
injured and non-injured knees. The other was
isokinetic CKC which was newly produced (OG
Giken, JAPAN) to assess the knee torque and knee
flexion angle at the maximum peak torque during
pressing down on the foot plate. We also
evaluated 13 healthy women (26 knees, mean age
22 year) with same methods as the control group
and statistically assessed the correlation between
OKC and CKC measurement of torque strength
around the knee joint.
RESULTS AND DISCUSSION:
There was statistically correlation between knee
extension and flexion torque in OKC and CKC
exercises. In ACL deficient knees, torque strength
of knee flexion and extension was significantly
