Bilateral spontaneous concurrent rupture of the patellar tendon without apparent associated systemic disease: a case report.

Patella tendon ruptures are an uncommon injury. Only 5 previous cases of bilateral patellar tendon rupture have been reported. Only 3 of these cases occurred simultaneously. All 5 previously described patients had systemic disease. This paper presents the only reported case of an individual with no known systemic disease who has suffered bilateral spontaneous concurrent patella tendon rupture.
