Simultaneous bilateral rupture of the patellar tendon is unfrequent and commonlyassociate to systemic disease and long-term corticotherapy. We described the case of a28-year-old woman with systemic lupus erythematous receiving steroids since 10 years. Spontaneously,she had bilateral rupture of patellar tendons. Surgical repair was performed by primarysuture augmented with transosseous suture and tendon plasty using fascia lata. Bothknees were immobilized in extension during 55 days, starting a physiotherapy program afterwards.Three months after surgery the patients regaired 90 degrees knee flexion and extensionhad no restrictions. The effect of the colagen disease and the prolonged corticotherapy on thetendinous degeneration and the different options for surgical repair are discussed.
