ABSTRACT

OBJETIVO: Descrever os achados epidemiológicos, clínicos e de ressonância magnética da osteonecrose das porções distal do fêmur e proximal da tíbia. MATERIAIS E MÉTODOS: Avaliação de 19 pacientes (12 mulheres e 7 homens), sem história prévia de fatores causais, com achados à ressonância magnética sugestivos de osteonecrose do platô tibial ou côndilo femoral. RESULTADOS: Verificou-se a presença de anormalidades osteocondrais em 63,1 por cento dos casos e em 73,6 por cento destes houve associação com lesão meniscal ipsilateral. Houve também importante associação com edema na medular óssea em correspondência (grau III em 16 casos). CONCLUSÃO: A ressonância magnética demonstrou ser um método não invasivo com boa sensibilidade no diagnóstico da osteonecrose do joelho, bem como das lesões associadas, sendo mais frequente nas mulheres (63 por cento dos casos).


OBJECTIVE: To describe epidemiological, clinical and magnetic resonance imaging findings of osteonecrosis in the distal femur and proximal tibia. MATERIALS AND METHODS: Evaluation of 19 patients (12 women and 7 men), with no previous history of causative factors, with magnetic resonance imaging findings suggestive of osteonecrosis in the tibial plateau or femoral condyle. RESULTS: Osteochondral abnormalities were observed in 63.1 percent of the cases; in 73.6 percent of them, such abnormality was associated with ipsilateral meniscal lesion. Also, a significant association with bone marrow edema (grade III in 16 cases) was observed. CONCLUSION: Magnetic resonance imaging has demonstrated to be a noninvasive method with good sensitivity in the diagnosis of knee osteonecrosis as well as of associated lesions which are most frequently found in women (63 percent of cases).
