A Rare Case of Post-Traumatic Partial Rupture of the Quadriceps Tendon

Traumatic ruptures of the quadriceps tendon are rare and usually occur after the age of 40, as a result of indirect trauma in athletes (contrary flexion of the knee) or minor trauma in sedentary individuals. Pre-existing tendinopathy is common. The rupture is most often complete and occurs at the body of the tendon in 60% of cases, or quadricipital avulsion at the upper edge of the patella (40% of cases). The diagnosis is primarily clinical, with complementary examinations (ultrasound and magnetic resonance imaging) playing a key role. Surgical treatment, combined with functional rehabilitation, produces better outcomes. The timing of intervention is a very important prognostic factor. We report a case of post-traumatic rupture of the quadriceps tendon in a 47-year-old patient.
