Abstract
Spontaneous rupture of quadriceps tendon (QT) is a rare condition and it is commonly associated with systemic comorbidities and medical products assumption, which may lead to tendon degeneration. While unilateral rupture is a quite common injury, spontaneous bilateral ruptures are very rare. Herein, we report two consecutive cases of spontaneous bilateral QT rupture in two patients with a positive history of chronic statin use, successfully treated with bilateral single-stage reconstruction with polyethylene-terephthalate tape augmentation. At 12 months of follow-up, both patients recovered the full extension, a 120° pain-free flexion and knee scores improvement. Magnetic resonance imaging at one year showed a complete, bilateral, bio-integration of the augmentation for each knee. In conclusion, polyethylene terephthalate tape augmentation provides a good structural support with a good grade of bio-integration, allowing a fast recovery.
