POSTER ABSTRACTS - ISAKOS

Situation 1-- Partial thickness ACD's;
Situation 2-- Femoral ACD's < 2 cm;
Situation 3-- Femoral ACD''s > 2 cm;
Situation 4-- Tibial ACD;
Situation 5-- Patellofemoral ACD isolated;
Situation 6-- Patellofemoral ACD combined;
Situation 7-- Ligamentous or meniscal deficiency;
Situation 8-- Bipolar ACD (femoral + tibial);
Situation 9-- Early OA (chondropenia);
Situation 10-- End-stage OA.
___________________________________________
Results: There were 90 male patients and 85
female patients with a mean age of 44 years (SD
16; range: 14-80 years). 3.4% had an isolated
femoral articular cartilage defect < 2 cm2. 2.3%
had an isloated femoral articular cartilage defect >
2cm2. Isolated tibial articular cartilage defects
were rare and only seen in 1.1%.

Situation 6-- 73 (9);
Situation 7-- 86 (14);

Situation 10-- 32 (3).

Conclusions: The CSS is an ojective and
quantifyable arthroscopic tool that reflects a
spectrum of injury to the articular and meniscal
cartilage. The Chondropenic Pathway is an
instrument used to stratify these patients into 1 of
10 situations. Both tools can be used together to
assess and translate arthroscopic findings into a
treatment algorithm.

A 66-year-old woman, whose case was
complicated by preexisting low platelet level,
which led to cirrhosis of the liver, presented with
continuous hemarthrosis after arthroscopic
meniscectomy. A second arthroscopy, performed
twelve days after initial operation, confirmed that
there was no bleeding in the joint. But
hemarthrosis was existing continuously. Ten days
after the second arthroscopy, thrombocyte
transfusion was administered, which successfully
rectified the hemarthrosis. Fifty days after initial
arthroscopy, a pulsatile swelling was noted
presented at the lateral arthroscopy portal,
subsequent angiography showed a
pseudoaneurysm of the lateral inferior genicular
artery. Surgical exploration and ligation of the
vessel feeding the pseudoaneurysm was
performed, and the patient made a full recovery.
Vascular injury should be considered in patients
Presenter with hemarthrosis following arthoscopy
of the knee.

Purpose:
To evaluate the long-term outcome following use
of osteochondral autografts for the treatment of
osteonecrosis of the femoral condyle.
Methods:
Clinical ,radiographic and arthroscopic findings
were evaluated at follow-up.Patients were 14
women and 2 men, with a mean age of 64.9 years
(range,58-74 years). The osteochondral lesion was
equivalent to Lotke 1-B in 12 knees, and was
equivalent to 1-C in 4 knees. Preoperative femoral
tibia angle ranged from 178 to 190 .
Resulls:
The follow-up period range from 28 months to 111
months (mean, 67 months).Functional scores
improved from 60 to 75 preoperatively to 80 to 100
postoperatively,And the grafts were satisfactorily
accepted. Patients with a femoral tibia angle of
less than 180 in particular were found to respond
favourably.
Conclusion:
Transplant surgery using osteochondral
autografting appeared effective for the treatment
of osteonecrosis of femoral condyle.
