[Spontaneous patellar tendon rupture as a result of morbid obesity].

We present the case of spontaneous damage to the patellar tendon in a patient with pathologic obesity (BMI = 41), without comorbid conditions. Damage occurred during normal load combined with the movement of the knee extension when inserting a foot in flip-flops. Surgical treatment was performed in a matter of urgency and the patellar tendon was sutured in half the length of. Six weeks of immobilization was used and then rehabilitation. After four months efficient gait and a good range of motion was achieved. Please note that obesity is a disease of civilization and cause further disease. These include acute injuries resulting from a sudden overload.
