Bilateral patellar tendon rupture: a case report

Abstract

<p>Bilateral patellar tendon rupture is a rare injury, usually associated with systemic disease or chronic medication side effect. Early diagnosis and prompt surgical repair are essential to achieve good functional outcomes. The authors report a case of a 44-year-old male with history of multiple urinary tract infection treated with fluoroquinolones who sustained spontaneous simultaneous bilateral patellar tendon rupture. Patient underwent bilateral transosseus tendon repair with autologous semitendinosus augmentation. Nine months after surgery, the patient was able to walk without pain and unassisted, had a normal range of motion in both knees and performed his daily activities without limitation. Surgical treatment of patellar tendon rupture is recommended to allow prevention of extensor mechanism disfunction sequelae. Transosseus tendon repair with autologous semitendinosus augment plasty is a valid surgical technique for treatment of this pathology with biomechanical and literature support.</p>
