SUMMARY
PEREIRA Jr., E. S. Comparative study the
morphologics, histochemicals and
immunohistochemicals characteristics of the
semitendinosus and gracilis muscles tendons
between genders. São Paulo, 2003. Tese de
Mestrado Universidade Federal de Sao Paulo -
Escola Paulista de Medicina.
The aim of this study was to compare the
morphologics, histochemicals and
immunohistochemicals characteristics of the
semitendinosus and gracilis muscles tendons
used in reconstruction of the anterior cruciate
ligament between genders. It was evaluated
samples of tendons of the semitendinosus and
gracilis in 36 patients (36 knees). The ages ranged
between 15 and 46, with average of 29,3 years old.
In relation to race, 33 were white and 3 not white,
and, to side, 23 knees were right and 13 left. The
patients were divided in two groups male (n=20)
and female (n=16). The samples of tendons were
submitted to histologics, histochemicals and
immunohistochemicals analysis. No significants
differences were observed between groups related
to age, gender, race, side, inflammation,
vascularity and alcianophilia. It was observed
increase in cellularity in semitendinosus muscles
tendons when compared gracilis muscles tendons
in both genders (male p=0,03* and female
p=0,22). It was observed a tendency in female
increase in calcifications in semitendinosus and
gracilis muscles tendons (p=0,06 and p=0,09), and
to increase in degeneration in collagens fibrils
semitendinosus muscles tendons (p=0,06). In
relation to estrogen receptors in semitendinosus
and gracilis muscles tendons it was observed
increase of number receptors in male patients.
The author concluded that are morphologics,
histochemicals and immunohistochemicals
differences in semitendinosus muscles tendons
between genders and between tendons itselves in
male.

The purpose of this study is to investigate the
possible relationship between a low plantar arch
and anterior cruciate ligament (ACL) injury.
[Subjects and methods] We obtained 100 foot
prints from 50 men with a history of ACL injury
and measured foot length, breadth and arch
height. The height per length, height per breadth,
and breadth per length were calculated and
compared between the injured side and the
uninjured side.
In addition, the results were compared between
those with a non-contact type of injury (n=30) and
those with a contact type of injury (n=20). As the
control group, 124 foot prints from 62 healthy
volunteers with normal ACL were examined.
Mann-Whitney test was used for the statistical
analysis of data.
[Results] In the injured side the average plantar
arch height per foot length was 0.076, the height
per breadth was 0.22, and the breadth per length
was 0.34. In the uninjured those values were
0.079, 0.23 and 0.35, and respectively with no
significant differences between the two sides. In
the group with non-contact type of injury (both
sides), the results were 0.081, 0.23 and 0.35,
respectively while in the contact type of injury
group, they were 0.074, 0.21 and 0.34, respectively,
with no significant differences between them.
On the other hand, in ACL injured cases (both
sides), the values of the investigated results were
0.077, 0.22 and 0.35, and in the control subjects,
they were 0.090, 0.22 and 0.35, respectively there
were significant differences between the ACL
injured group and the control, in the plantar arch
height per foot length (p
