Introduction: We conduct a systematic and qualitative review of the current literature to evaluate studies that described bilateral ruptures of the extensor mechanism of the knee.
Methods: A comprehensive literature search was performed to evaluate all studies included in the literature until September 2016.
Results: Fourteen studies with a total of 44 patients met the inclusion criteria. There were 14 patients with CRF (61%), 6 patients were affected by diabetes mellitus (14%) while other 6 patients were obese patients (14%).
Conclusion: CRF represents the most frequent comorbidity in patients with bilateral quadriceps/patellar tendon ruptures.
