Bilateral, simultaneous, spontaneous rupture of quadriceps tendons without trauma in an obese patient: a case report

Abstract

This is a single case report of bilateral, simultaneous, spontaneous rupture of the quadriceps tendon caused by obesity without trauma. The patient was a 52-year-old, 350-pound, morbidly obese man with a sedentary life style whose quadriceps tendons ruptured while he was descending a staircase. He presented with a large deficit superior to the patella and an inability to straighten his knees. After surgery, his knees were immobilized in extension for 6 weeks, followed by gradual weight bearing and gait training with braces. He was weaned off the braces as he increased the range of motion and strength in his knees. The rehabilitation process was protracted, and he returned to full-time work 6 months postinjury. Physiatrists should be familiar with the diagnosis, treatment, and rehabilitation of this rare condition.
