POSTER ABSTRACTS - ISAKOS

partial ACL tear and one MCL tear. There were
four lateral meniscal repairs and two partial
lateral meniscectomies performed. The clinical
and radiological outcomes were determined
according to Rasmussen’s system. In 9 patients,
second look arthroscopy was performed 10 to 15
months after there index procedure and we
evaluated intraarticular lesions including menisci
and cartilage. Results: There were no episodes of
nonunion, failure of fixation, wound infection,
compartment syndrome, or arthrofibrosis. Overall,
6 (55%) patients were rated as excellent, 4 (36%)
good, and 1 (9%) fair. All type-3 patients were
rated excellent in every factors. Preoperative
fracture depression averaged 10.7 mm (range, 6 to
23 mm). Fracture depression at final follow up
averaged 1.7 mm (range, 0 to 5 mm). Second look
arthroscopy revealed all repaired menisci were
healed and there could be seen some superficial
fissures and cracks of cartilage. Conclusions:
Arthroscopic reduction and internal fixation
provides an accurate fracture reduction, diagnosis
and treatment of associated intraarticular injuries.
The arthroscopic technique allows less soft tissue
stripping than with traditional methods.

The aim of this study is to investigate the onset of
VMO and VL muscle activity in straight leg raise
position with neutral, 30 internal and 45 external
hip rotation and with/ without patellar taping and
with/without Thera-band in healthy subjects.
Thirty-seven knees of nineteen male subjects were
evaluated electrophysiologically. The subjects
with a history of knee trauma or surgery,
patellofemoral pathology, or different skinfold
value between knees were excluded from our
study. EMG activity was recorded with surface
electrodes in an oscilloscope program from the
VMO and VL muscles. VMO started to contract
before VL in only two examination procedures: 30º
IR without patellar taping and Thera-band, and
30º IR with patellar taping and without Theraband.
In all the other examination procedures VL
started to contract earlier than VMO, though no
statistical significance between onset activities of
VMO and VL was found in any of our examination
procedures. Although no differences were found
between onset activities of VMO and VL muscles
in our study, patellar taping and SLR exercises
were used for treatment of patients with
patellofemoral pain by increasing VMO activity,
correcting patellar position and decreasing the
pain.
Key Words: Onset activity, VMO and VL muscle,
Patellar Taping, Thera-band, Hip Rotation Angle.

Introduction: Giant cell tumor of the patellar
tendon is relatively common injuries of fibrosis
proliferation in the orthopaedic practice. It occurs
predominantly in women in a ratio of 2:1 in
relation to men, and it is caracterized as a
concrete and painless mass. Generally, they are
located in the palmar region of the fingers and
have ample distributions; having stories of
manifestations in individuals of 8 to 80 years.
However, this tumoral presentation in the patellar
tendon, with bilateral manifestation
concomitantly, is rare. The ability to make the
diagnosis appropriately and to treat benign
tumors adequately, as well as distinguishing them
from the malignant injuries consists of a vital
quality for the orthopaedic surgeon. Objective: To
report a case of giant cell tumor in patellar tendon
and to carry through pertinent bibliographical
revision. Material and Method: Patient F.K,
masculine, 16 years, student, presented with
bilateral masses in patellar tendon topographies,
with a diameter of 4 cm of the right side and of 7
cm of the opposing side, of fibro-elastic
caracteristics, mobile and painless. They did not
present signs of infection or inflamatory signals.
The patient denied any previous history of pain or
trauma. Results: X-rays had been inconclusive for
