Simultaneous rupture of quadriceps and contra-lateral patellar tendons represents an extremely rare injury in healthy individuals. Several systemic diseases predispose patients to this type of condition such as chronic renal failure, rheumatologic disease and hyperparathyroidism. However, there are very few cases in the English literature where a healthy individual presents with this condition. The pathophysiology of this disease is not well known despite numerous hypotheses. Sutures with or without anchors of the quadriceps and patellar tendons seems to lead to satisfactory outcome with knee flexion greater than 100°.
Keywords: Simultaneous rupture; knee injuries; patellar tendon; quadriceps tendon.
