the diagnosis. The ultrasonography presented
suggestive images of soft tissue tumors. The
histologic study of the excisionais parts detected
histiocitics cells and multinucleated giant cells,
confirming the diagnosis. Conclusions: The giant
cells tumors had been removed by aesthetic
questions. However, it has necessity of surgical
intervention when it has manifestations of
compressive pictures of adjacent structures or
when malignancy must be discarded. All
orthopaedic surgeon must be familiar to the
evaluation of the tumoral processes in this region
to differentiate of other orthopaedic diseases.

Background: Ruptures of the quadriceps tendon
(QT) are a common problem in the middle age
patient. The density of vascularity of the tendon
may explain the pattern of spontaneous ruptures
of the QT. Our purpose was to describe the
vascular anatomy of the QT and assess the density
of vascularity in an attempt to correlate
hypovascular areas with the clinical pattern of
ruptures. Methods: Twenty adult human cadavers
underwent whole body arterial perfusion with 26
ml/kg of a mixture of lead oxide, gelatine and
water though the femoral artery. All quadriceps
musculotendinous units were dissected and
radiographed. The obtained angiograms were
scanned to a computer, converted to digital
pictures and analized with a digital picture
statistical software analyzer. Pixel-maps based on
the radio-opacity of the vessels of the tendon
were created. Results: Three main anastomotic
arcades were identified, and based on the density
of vessels observed, different vascular zones were
described: Zone I, located between 0 and 1 cm
from the proximal edge of the patella, contains
the superior peri-patellar arcade and is highly
vascularized. Zone II (intermediate) located
between 1 and 2 cm was found to be hypovascular
mainly in its central third, also in some specimens
avascularity of central zone II was noted; zone III,
located from 2 cm beyond the patella to the
musculotendinous junction showed a variable
vascular supply, rich near the laterals portions
and poor at the center of the tendon.
Conclusion: The hypovascular zones identified,
correlate with the clinical pattern of rupture of
the QT.

Purpose :
It is to analyze clinical cure and patient’s
satisfaction according to the affecting factors after
applying arthroscopic inside-to-out suture on the
tear of meniscus, using nonabsorbable suture
material.
Subjects and methods:
The subjects are 110 cases of 95 patients who
were able to be follwed up for more than 12
months (from Aug. 1999 ~ June 2002), after
arthroscopic inside-to-out suture treatment was
given for the tear of meniscus, using
nonabsorbable suture material. The results were
evaluated in terms of clinical cure and subjective
satisfaction level, which were followed by an
analysis of effects of age, period from the injury
occurrence to operation, tear site, tear length,
type of tear, injury level of articular cartilage and
accompanying anterior cruciate ligament
operation on the results.
Results:
Clinical cure accounts for 76% of 84 cases, while
patients’ subjective satisfaction for 89% of 98
cases. In case of accompanying tear of anterior
cruciate ligament, tear length of less 2 cm and
light case of degeneration in articular cartilage
show significantly higher clinical cure and
patients’ satisfaction levels. In case of the tear of
medial meniscus, shorter period from the injury
occurrence to operation and longitudinal tears
among many types of tears show higher level of
clinical cure. Complicated or degenerative tears
show high level of patients’ satisfaction despite
lower level of clinical cure.
Conclusion :
The arthroscopic inside-to-out suture on
meniscus using nonabsorbable suture material is
an easy technique that allows a variety of sutures.
It can be concluded that patients’ age is not
absolute consideration in determining the suture
