This study reviewed 55 case reports of simultaneous and bilateral quadriceps tendon rupture and analyzed factors related to outcomes. Mean patient age was 52 years and 82% of patients were male. Most patients (76%) had underlying medical conditions predisposing them to rupture and 16 (32%) patients had multiple risk factors. Falls accounted for a majority of injuries (72%) and the osseotendinous junction was frequently the location of the tear (60%). Patients were almost always treated surgically (96%). Gender, mechanism of injury, tear location, and time to diagnosis and repair were not related to outcomes, whereas age, multiple risk factors, and renal or endocrine disease or diabetes were related to outcomes.
