[Bilateral intra-patellar tendon rupture in a previously healthy woman].

Bilateral infrapatellar tendon rupture is a relatively rare injury. We describe the case of a 32 year old woman who stumbled and sustained a bilateral infrapatellar tendon rupture while jogging. In our opinion, this represents an unusual mechanism of injury, and we also find it unusual that it was a bilateral injury in an otherwise healthy patient. Diagnosis was confirmed by surgical exploration eight days after admission to hospital. Despite repeated clinical, X-ray and ultrasound examinations, the diagnosis was delayed since we initially did not consider the trauma adequate to cause such an extensive injury. The diagnosis of patella tendon rupture should be based on careful consideration of the history of the injury and thorough clinical examination. X-ray and ultrasound can be of diagnostic help.
