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

The diagnosis is usually made clinically, but ultrasound or MRI can be used if there is any doubt.

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.
