A quadriceps tendon rupture is a severe and debilitating injury that occurs when the tendon connecting the quadriceps muscle to the patella (kneecap) tears. This condition is relatively rare and typically results from a forceful impact or sudden, intense contraction of the quadriceps muscle.

Causes

Quadriceps tendon ruptures are often caused by a sudden, forceful impact to the knee or a rapid contraction of the quadriceps muscle. This can occur during high-impact sports or physical activities, such as football, basketball, or weightlifting. Other risk factors include aging, obesity, and certain medical conditions, such as diabetes and rheumatoid arthritis.

Symptoms

The primary symptom of a quadriceps tendon rupture is a sudden, severe pain in the front of the knee. This is often accompanied by an inability to straighten the knee or walk without assistance. Other symptoms may include swelling, bruising, and a palpable gap above the kneecap where the tendon has torn.

Diagnosis

Diagnosis of a quadriceps tendon rupture typically involves a physical examination and imaging tests. During the physical examination, the doctor will assess the knee's range of motion and look for signs of injury. Imaging tests, such as an X-ray or MRI, may be used to confirm the diagnosis and assess the severity of the injury.

Treatment

Treatment for a quadriceps tendon rupture typically involves surgery to reattach the torn tendon to the kneecap. This is usually followed by a period of physical therapy to restore strength and mobility to the knee. In some cases, non-surgical treatments, such as bracing and physical therapy, may be used for patients who are not suitable candidates for surgery.

Prognosis

With prompt treatment and proper rehabilitation, most patients can expect to regain full function of their knee. However, the recovery process can be lengthy and may require several months of physical therapy.
