POSTER ABSTRACTS - ISAKOS

patients who had cyclops showed loss of knee
extension (5~10 ), which was regained by
resection of the cyclops. One patient who had an
interposition into the lateral joint space
complained of catching which was released by
resection of the interposing tissue. Conclusion:
Cyclops syndrome, which is recognized following
anterior cruciate ligament reconstruction, is one
of the causes of loss of knee extension after
surgery to repair a fracture of the intercondylar
eminence. Furthermore, in those cases that have
knee complaints such as catching and loss of knee
extension, second-look arthroscopy is important
to identify and correct the problem.

Our purpose is to test the hypothesis that efficacy
of knee posterior compartment arthroscopic
evaluation outweighs morbidity or inefficiency.
100 consecutive knee arthroscopy patients have
posteromedial and posterolateral evaluation
according to an algorithm designed to minimize
inefficient technique(s). Number of attempts
required for visualization (or visualization not
accomplished), morbidity (scuffing or
complications), and findings are recorded. Loose
bodies are defined as expected when preoperative
imaging or arthroscopy of the rest of the
knee reveals loose bodies.
With regard to posteromedial, inserting the
camera directly (no obdurator) may result in
instrument breakage. 82 percent were visualized
on the first attempt. 3 percent were not
accomplished. 34 percent had scuffing. Loose
bodies were found in 36 percent when expected
and 0 percent when not expected, a significant
difference (p less than 0.05). 5 findings were
recorded in addition to loose bodies.
With regard to posterolateral, 93 percent were
visualized on the first attempt, inserting the
camera directly via the anterolateral portal. All
were visualized. 4 percent had scuffing. Scuffing
occured significantly less frequently than with
posteromedial (p less than 0.05). No findings
were recorded.
Despite inefficiency, we recommend
posteromedial visualization via the anterolateral
portal using an obdurator. Posteromedial
visualization is associated with morbidity but is
efficacious in some cases and strongly
recommended when loose bodies are expected.
Posterolateral visualization directly with the
camera via the anterolateral portal is efficient and
associated with minimal morbidity but was not
efficacious in the cohort evaluated.

Arthroscopic meniscal repair is a promising
technique for treating peripheral meniscal tear.
Aim: Assess clinical results and satisfaction after
meniscal repair in District General Hospital set
up.
Material and methods: Retrospective analysis of
patients’ details who had meniscal repair between
January 1996 and December 2001.Various data
regarding occupation, mechanism of injury,
waiting time before diagnosis and surgery and
type of repair carried out was gathered from
patients notes. A questionnaire was sent to all
these patients regarding satisfaction, recovery and
function based on international knee scoring
criterion.
Results: During this period total of 69
arthroscopic meniscal repair were carried out (Age
group 9-65 years.).About 60% of patients had
sporting injury and about 70% had operation
within six months of their injury. Mean duration at
the time of review was 31 months (60-12 months).
Methods of repair were vicryl suture, darts, clearfix
screw fixation and combination two different
methods.84% of the patients were back to normal
activity and sporting activity by 12 weeks and
remaining had associated procedures like ACL
reconstruction which delayed their progress. 72%
of patients had normal knee function. 4 patients
out of 69 had failure of the procedure and
required subsequent excision of meniscus.
