A quadriceps tendon rupture is a tear of the tendon that runs from the quadriceps muscle to the top of the knee cap.[1]
Signs and symptoms
[edit]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
[edit]The diagnosis is usually made clinically, but ultrasound or MRI can be used if there is any doubt.

Treatment
[edit]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.[citation needed]
