This injury is often associated with significant pain, swelling, and an inability to extend the knee.

==Anatomy==
The [[quadriceps tendon]] is a strong, fibrous tissue that attaches the [[quadriceps femoris]] muscle group to the [[patella]]. The quadriceps femoris is composed of four muscles: the [[rectus femoris]], [[vastus lateralis]], [[vastus medialis]], and [[vastus intermedius]]. These muscles work together to extend the knee and are crucial for activities such as walking, running, and jumping.

==Causes==
Quadriceps tendon ruptures can occur due to a variety of reasons, including:
* [[Trauma]]: Direct impact to the knee or a sudden, forceful contraction of the quadriceps muscle.
* [[Degenerative changes]]: Chronic conditions such as [[tendinitis]] or [[tendinosis]] can weaken the tendon over time.
* [[Systemic diseases]]: Conditions like [[diabetes mellitus]], [[rheumatoid arthritis]], and [[chronic kidney disease]] can predispose individuals to tendon injuries.
* [[Medications]]: Long-term use of certain medications, such as [[corticosteroids]] and [[fluoroquinolones]], can increase the risk of tendon rupture.

==Symptoms==
The primary symptoms of a quadriceps tendon rupture include:
* Sudden, severe pain at the front of the knee.
* Swelling and bruising around the knee.
* A palpable gap above the patella where the tendon has torn.
* Inability to straighten the knee or perform a straight-leg raise.
* Difficulty walking or bearing weight on the affected leg.

==Diagnosis==
Diagnosis of a quadriceps tendon rupture typically involves:
* [[Physical examination]]: A healthcare provider will assess the knee for signs of swelling, tenderness, and the ability to extend the leg.
* [[Imaging studies]]: [[X-rays]] can help rule out fractures, while [[magnetic resonance imaging]] (MRI) or [[ultrasound]] can confirm the extent of the tendon injury.
