Quadriceps tendon rupture

Introduction to quadriceps tendon rupture The knee extension device consists of the quadriceps, the tibia and the ankle. When the peak contraction force of the quadriceps exceeds the mechanical load limit of a weak part of the knee extension device, it will cause a fracture of the knee extension device, including a tibial fracture. The fracture of the knee extension device may be an incomplete fracture, that is, microscopic tearing of part of the collagen fibers, which reduces the tension of the knee extension device and increases the length, and the direct cutting injury can also cause the fracture of the quadriceps or tendon. . basic knowledge The proportion of illness: 0.04%-0.08% Susceptible people: people who are more than 40 years old Mode of infection: non-infectious Complications: knee injury

Causes of quadriceps tendon rupture

Cause:

Because the injury of the knee extension device is usually caused by sudden flexion of the knee joint and sudden and severe contraction of the quadriceps muscle, and at this time, the humerus is the fulcrum of the entire knee extension device on the femoral condyle, therefore, the knee extension device The injury is more common in the fracture of the tibia, while the fracture of the quadriceps tendon and tendon is relatively rare.

Pathogenesis

Complete rupture of the quadriceps tendon is not very common. The typical trauma mechanism is a sudden strong protective contraction of the quadriceps in the unprepared flexion of the knee (such as a collapsed state) resulting in degenerative or weak quadriceps tendon fracture.

Quadriceps tendon rupture prevention

The initial surgical treatment is the main link. The disease is caused by traumatic factors. Therefore, paying attention to production and life safety is the key to preventing this disease. In social production activities, production is carried out through the harmonious operation of people, machines, materials, environment and methods. The potential accident risks and damage factors in the process are always in an effective state of control, and the lives and health of workers are effectively protected.

Quadriceps tendon rupture complications Complications knee injury

The injured part is swollen and bloody, the meridian is unreasonable, and the blood and blood is blocked. In this stage, the treatment is to promote blood circulation and remove phlegm. Chinese medicine believes that "If you don't go, you can't give birth to bones," and "go to new bones." It can be seen that swelling and dissipating phlegm is the primary of fracture healing. Severe cases may be complicated by blood stasis and difficult to dissipate, which will delay the course of the disease, delay the growth of the epiphysis, and affect the recovery of joint function in the future.

Quadriceps tendon rupture symptoms Common symptoms Tendon rupture tibia pain Knee joint swelling Blood stasis Zhouzhi tenderness Knee extension Obstruction quadriceps injury Biceps injury

More people occur in people over the age of 40. The location of the fracture is mostly near the upper edge of the humerus. After the trauma, the patient has a typical knee extension, tenderness on the ankle, hemorrhage of the upper sac, and a quadrant of the quadriceps tendon.

Examination of quadriceps tendon rupture

1. Lateral X-ray of the knee joint, showing the shadow of the quadriceps of the quadriceps.

2. Magnetic resonance imaging (MRI) examination, due to high resolution of soft tissue synovium, blood vessels, nerves, muscles, tendons, ligaments, and hyaline cartilage, for inflammation of the synovium, blood vessels and muscles, fascia, synovium Clinical examination of cyst and hyaline cartilage degeneration, exfoliation and erosion and ischemic necrosis, cervical and nucleus lesions, knee meniscus and cruciate ligament injury, rheumatoid neurological complications and osteomyelitis.

Diagnosis and diagnosis of quadriceps tendon rupture

Should be differentiated from tendinitis, the cause of tendinitis is mostly unknown. Most of the patients are middle-aged and elderly, and often cause major damage due to poor blood supply to the tendon and repeated minor trauma. Repeated or severe trauma (incomplete fracture), strain, overwork (due to incompatibility), etc., are the most common possible causes of illness. A tenderness near the joint or joint, especially the heel (herein referred to as Achilles Achilles tendon).
