POSTER ABSTRACTS - ISAKOS

and female soccer players between 10 and 75 of
flexion. Using average deviation values, a onetailed
t-test performed at each interval
determined that there was a statistically
significant difference between the two
populations at multiple angles with the greatest
statistical significance (95% confidence level)
noted between 10 and 30 degrees of knee flexion--
the position where most ACL injuries are believed
to occur. Moreover, there was no statistical
difference between 40 and 60 degrees of knee
flexion, the proported safe zone from ACL injury.
CONCLUSION: Women and men at the collegiate
level exhibit statistically different proprioception
abilities when measured in a closed chain, i.e., a
functionally relevant position. This is particularly
evident at those knee flexion angles that generally
correlate with the risk of ACL injury, namely less
than 30 degrees of knee flexion. Moreover, no
statistical differences were noted between flexion
angles of 40 and 60 degrees, angles associated
with the least risk of ACL injury.

Long-term outcome of anterior cruciate ligament
reconstruction is dependent on surgical technique
and post-operative rehabilitation. Whilst surgical
techniques are well established rehabilitation
protocols are largely dependent on the surgeon´s
preference. Studies also suggested that noncompliant
patients progressed more rapidly with
fewer motion problems without compromise of
knee stability and outcome. This raises the
question as to the necessity of supervised
rehabilitation in non-professional athletes. The
purpose of this study was to establish whether
there was a difference between a group of patients
who underwent rehabilitation supervised by a
physicial therapist after anterior cruciate ligament
reconstruction with a group who performed unsupervised,
home based rehabilitation. Fifty ACL
deficient patients underwent anterior cruciate
ligament reconstruction with bone-patella tendon
graft performed by the same surgeon were
randomly allocated to the physical therapy or
home based group. Pre and post surgery all
patients were assessed up by an independent
examiner.IKDC, Lysholm and Tegner scores were
assessed pre-surgery, three, six, nine and twelve
months post surgery. Bilateral concentric and
eccentric isokentic strength testing for the
quadriceps and hamstring muscles and single leg
hop tests were performed. Repeated measures of
ANOVA revealed no significant differences
