POSTER ABSTRACTS - ISAKOS

PURPOSE:
The purpose of this study was to determine the
pathogenesis of osteochondritis
dissecans(OCD)of the lateral femoral condyle
associated with lateral discoid meniscus injury.
MATERIALS AND METHODS:
Between January 1999 and August 2003, a total of
47 patients (58 knees) underwent arthroscopic
surgery for a lateral discoid meniscus tear at our
hospital. Six males (7 knees) had concomitant
OCD of the lateral femoral condyle (Group I, mean
age 11.3 years). Group II consisted of 7 male
patients (8 knees) with lateral discoid meniscus
injury without OCD (mean age 13 years). Thirteen
males (13 knees) with a normal meniscus were
randomly sampled as a control group. The clinical
symptoms and knee alignment of these patients
were evaluated. The femoro-tibial angle (FTA),
femoral condyle angle (FCA) and tibial plateau
angle (TPA) were measured on plain
roentgenograms. Statistical analysis was
performed using Student’s t-test and analysis of
variance (ANOVA).
RESULTS:
The FTA in Group I and Group II were 172.86±0.9
and 176.86±1.96 degrees (p
