POSTER ABSTRACTS - ISAKOS

posterior horn of the medial meniscus. There were
no findings of ON in these studies. Reevaluation
with MRI revealed abnormalities at the medial
femoral condyle consistent with ON.
The mean time from initial MRI to second MRI
was 3.5 months. The size of the osteonecrotic
image showed at the MRI was measured, and
values obtained averaged 21%.
The development of osteonecrosis following
arthroscopic knee surgery is rare, but the role of
the procedure may be questioned.
Our data support the contention that meniscal
injury may be the first event, followed by the
development of ON of the knee without
meniscectomy arthroscopy.
This series would elucidate the natural sequence
of events as well as rule out arthroscopic
procedure as a cause. Elderly patients with medial
meniscal tears should be alerted of this potential
sequence of events and the impossibility at that
stage to predict or prevent this situation, specially
before performing an arthroscopic menisectomy.

Arthroscopic posterior cruciate ligament (PCL)
reconstruction may carry risk of complications,
including injury to the neurovascular structures in
the popliteal region. However, to our knowledge,
its occurence during arthroscopic PCL surgery has
not been reported. We report a case of acute
popliteal artery laceration during arthroscopic
PCL reconstruction.
Surgery presented no complication and when the
tourniquet was removed a sudden decrease of the
blood presure was detected and copious bleeding
from the posteromedial incision ocurred. A
intraoperative angiography showed extravasation
of the contrast through the anterior aspect of the
popliteal artery. A vascular surgeon applied a
saphenous vein graft to the laceration and fixed it.
The patient underwent a standard rehabilitation
protocol without any complication.
This injury may occur during the creation of the
posteromedial portal, the manipulation of the
tissues in the posterior part of the capsulae of the
knee joint or drilling the tibial hole.
If an injury to the popliteal artery is suspected,
immediate consultation with a specialst in
vascular surgery is mandatory.
Prompt arteriography and vascular repair is
indicated in view of the high rate of amputation
that is associated with this injury.
Surgeons should be aware of this potential
problem and should protect the soft tissue on the
posterior tibia distal to the insertion of the PCL.

INTRODUCTION: osteitis pubis is a common
cause of pain in the groin and pubis areas in
soccer players who perform repetitive movements
of kicking during training and games.
PURPOSE: to determine a routine of clinical and
subsidiary evaluation of the osteitis pubis as well
as surgical treatment and physical therapy.
METHOD: 20 (twenty) male soccer players with
ages ranging from 18 to 30 years, complaining of
pain in the groin and pubis area for over 12
months and without improvement with
conservative treatment were prospectively
evaluated. The patients were submitted to a
routine of clinical evaluation, including specific
maneuvers and image tests (XR and MR) and
submitted to surgical treatment predominantly
consisting of debridement of symphisis pubis
adductor tenotomy. Patients were submitted to
physical therapy, returning to sports activity after
a mean period of 6 weeks .
CONCLUSION: Diagnostic and surgical routine
allowed a standardization to conduct osteitis
pubis, returning to sports activity with
improvement of pain.
