Resumen
BRITO, Joaquim Soares do; PADIN, José; MARTINS, Samuel y MONTEIRO, Jacinto. Osteonecrose do Joelho. Rev. Port. Ortop. Traum. [online]. 2015, vol.23, n.2, pp.149-159. ISSN 1646-2122.
Spontaneous (SO), secondary (SCO) and post-arthroscopic (PO) osteonecrosis are three distinct pathological entities of knee osteonecrosis. The real incidence is unknown and clinical evaluation supported by imaging studies is fundamental, allowing prognosis establishment and differential diagnosis with other knee pathologies. Although the pathogenesis, risk factors and associated diagnosis have been widely studied none of these entities is fully understood. To establish the diagnosis, conventional radiography and bone scan remain important exams, however, magnetic resonance imaging (MRI) is currently the gold standard. Several treatment options have been described for each of these entities with different success rates, depending on the patient and the underlying pathogenesis.
