A quadriceps tendon rupture is a tear of the strong, fibrous tendon located at the top of the kneecap (patella) that connects the quadriceps muscles to the kneecap. It works with the quadriceps muscles to allow you to straighten your leg. The rupture can be partial, where some fibers are torn, or complete, where the soft tissue is severed and the muscle is no longer attached to the kneecap. Large ruptures are disabling and usually require surgery.
Causes and Symptoms
This injury is most common in middle-aged people who play sports involving jumping and running. It can be caused by a fall, a direct blow to the leg, or landing awkwardly from a jump. Other causes include tendinitis, diseases like rheumatoid arthritis or diabetes, and certain medications (steroids, some antibiotics) that weaken tendons. Common symptoms include a popping sensation, pain, swelling, bruising, and the inability to straighten the leg. You may also notice a depression at the top of the kneecap.
Diagnosis and Treatment
Diagnosis is based on medical history, a physical exam, and imaging tests like X-rays or an MRI to confirm the rupture's location and extent. Treatment can be non-surgical for small or partial tears, involving a knee brace or immobilizer and crutches.
