POSTER ABSTRACTS - ISAKOS

Lysholm, ADL, and IKDC all showed average
scores poorer than those of historical controls.
There was no statistically significant difference
between graft type, organism (S. Aureus versus S.
Epidermis), or graft retention versus removal. Of
the 5 patients on whom radiographs were
obtained, all showed signs of degenerative
changes.
DISCUSSION: Patients with septic arthritis
following ACL reconstruction have lower
functional scores after 6 years than do those with
uncomplicated ACL reconstruction.

Revision ACL due to Posterolateral
Insuffuciency

Lesion of the popliteus fibular ligament and the
popliteus tendon with or without rupture of the
lateral collateral ligament is often referred to as
lesion of the postero-lateral corner of the knee.
The postero-lateral corner is involved in 4% of all
knee-ligament injuries giving an incidence of less
than 0.1 per 1.000 per year. Lesion of the posterolateral
corner is often related to either rupture of
the anterior or posterior cruciate ligament.
Untreated lesion of the postero-lateral corner will
lead to rotatory instability. Undiagnosed lesion
can lead to failure of primary anterior cruciate
ligament reconstruction. Of 136 revision ACL
reconstructions 29 were due to postero-lateral
instability. In 6 cases ligamentous insufficiency
after ACL reconstruction were caused by posterolateral
instability alone, and could be treated with
concomitant PLC/LCL reconstruction.
In 10 cases one or more revision ACL
reconstruction had been performed prior to
diagnose of postero-lteral instability.
In revision cases ACL revision with either patella
tendon -,hamstrings tendons autografts or
allografts was combined with reconstruction of
the posterolateral corner. Through a lateral hockey
stick approach the proximal tibia and fibula were
exposed as well as the anatomical insertion
points of the lateral collateral ligament and the
popliteus tendon at the femoral epicondyle. Drillholes
through head of fibula, proximal tibia and
femur were done and a reconstruction of the
lateral collateral and the popliteus tendon with
semitendinosus and gracilis graft was performed.
Patients were evaluated with IKDC evaluation
after minimum 10 months and KOOS
questionnaire after 24 months. The stability
according to KT1000 evaluation gained from the
combined reconstruction of the posterolateral
corner and revision ACL.

Introduction: Self-reported patient outcomes
following primary ACL reconstruction using
allograft tissues were compared to patient
education level, sports activity level and age
group classification. Methods: The Demographic,
Subjective Knee Evaluation, and Current Health
Assessment components of the IKDC 2000 Knee
Forms, the Knee Outcome Survey Activities of
Daily Living Scale and the Knee Outcome Survey
Sports Activity Scale were mailed to 335 subjects
at > 2 years following ACL reconstruction.
Multiple regression analysis was used to analyze
the influence of patient self-reported education
level (1 = < high school, 2 = high school graduate,
3 = some college, 4 = college graduate, 5 =
postgraduate school), sports activity level (1 =
non-sporting, 2 = sporting sometimes, 3 = welltrained
and frequently sporting, and 4 = highly
competitive), and age group classification (1 = <
18 yrs, 2 = 19-25 yrs, 3 = 26-38 yrs, 4 = > 38 yrs).
Results: Surveys were completed by 188 subjects
(95 male, 93 female, 56% return). Patients were 5
± 2.8 years post-surgery (range = 2-12 years).
Time post-surgery was slightly greater for age
group 1 than for group 4 (P = 0.001) but did not
differ between sports activity level groups (P =
0.70) or education level (P = 0.79). Groups had
similar numbers of female and male subjects
based on age group
(P = 0.68), education level (P = 0.39) and sports
activity level (P = 0.08). Multiple regression
analysis revealed that education level (beta =
0.40) and sports activity level (beta = 0.35)
predicted 31.4% of Knee Outcome Survey
Activities of Daily Living Scale scores. Education
level (beta = 0.35) and sports activity level (beta =
0.36) predicted 27.7% of Knee Outcome Survey
