A quadriceps tendon rupture is a tear of the tendon that runs from the quadriceps muscle to the top of the knee cap.{{Cite web|date=2017-07-19|title=Quadriceps Tendon Rupture: Practice Essentials, Anatomy, Pathophysiology|url=https://emedicine.medscape.com/article/1249621-overview}}
Signs and symptoms
Symptoms are pain and the inability to extend the knee against resistance. A gap can often be palpated at the tendon's normal location.
Diagnosis

Treatment
The tendon can be surgically repaired. Afterwards a brace is given that prevents flexion of the knee. Athletes who have had this injury generally return to action in about 9 months to a year.{{cn|date=July 2022}}
