[Bilateral rupture of the quadriceps tendon]

Simultaneous, bilateral, and spontaneous rupture of the quadriceps tendon is a very rare injury. Individuals with this injury are usually predisposed by chronic renal disease with secondary hyperparathyroidism, gout, diabetes, and lupus erythematosus. Often, primary diagnostic confusion can lead to a delay in treatment. Two cases of a bilateral lesion of the quadriceps tendon, that were treated surgically using the technique of Scuderi, followed by an intense rehabilitation programme, are presented. Surgical treatment yields satisfactory results.
