ABSTRACT

Objectives: To review radiographs of patients who suffered tendon tears of the knee extensor apparatus and observe alterations that might be factors predisposing toward this type of injury. Methods: We retrospectively analyzed 60 cases of injury to the knee extensor mechanism that were treated surgically at the Miguel Couto Municipal Hospital between March 2004 and March 2011. Four patients were excluded due to poor quality of the examination. Results: Of the 56 patients evaluated, 23 were considered to be normal and 33 presented radiographic alterations. Among these, eight (24.3%) presented suprapatellar osteophytes alone; seven (21.2%), infrapatellar calcification; seven (21.2%), suprapatellar calcification; six (18.2%), supra- and infrapatellar osteophytes; and five (15.1%), infrapatellar osteophytes alone. Conclusion: Radiographic alterations were frequently observed in patients with extensor mechanism tears...

Resultados: Dos 56 pacientes avaliados, 23 foram considerados normais e 33 apresentaram alterações radiográficas, oito (24,3%) com presença de osteófito suprapatelar isolado, sete (21,2%) com calcificação infrapatelar, sete (21,2%) com calcificação suprapatelar, seis (18,2%) com osteófitos supra e infrapatelares e cinco (15,1%) com osteófito infrapatelar isolado. Conclusão: As alterações radiográficas foram frequentes em pacientes com ruptura do mecanismo extensor...
