Bilateral Patellar Tendon Rupture: Obesity as a Risk Factor

Introduction Bilateral patellar tendon rupture is an uncommon presentation in the Emergency Department but can occur in the setting of certain risk factors. Obesity is an independent predisposing condition in which early identification can expedite diagnosis and treatment. Case Description We report a case of bilateral patellar tendon rupture in a young male with obesity as the sole risk factor following a low-energy trauma. The patient ruptured his bilateral patellar tendons while jumping up during a basketball game. The diagnosis was made on exam and confirmed with plain radiographs and Magnetic Resonance Imaging. Because of the bilateral involvement and inability to bear weight, he underwent urgent primary repair and subsequent physical therapy. Discussion Bilateral tendon rupture is a rare event. Prior case reports have noted risk factors such as medications including corticosteroids and fluoroquinolones. Certain medical conditions can also increase risk of bilateral rupture including diabetes, chronic kidney disease and collagen disorders. Our case is unique in that the patient did not have any of the previously noted risk factors. He did have morbid obesity which may have impacted his tendon integrity.
