How to judge patellar tendon rupture?
summary
Patellar tendon rupture is usually avulsion of the lower edge of the patella, and avulsion of the tibial tubercle at the distal end of the patellar tendon. Due to the contraction of quadriceps femoris, patella can retract 3-6cm with quadriceps femoris tendon. Therefore, early repair of patellar tendon rupture should be emphasized. Because of the contracture and scarring of patellar tendon in late stage, reconstruction operation is often necessary. How to judge patellar tendon rupture?
How to judge patellar tendon rupture?
After injury, patients with knee extension examination can have knee extension disorder, fracture tenderness, hematocele, patellar tendon discontinuous emptiness, patella upward. The local tenderness is obvious, the surrounding skin is blue and swollen, abnormal activities can be seen, unable to stand, etc.
Common symptoms: knee injury, swelling of the anterior and inferior side of the knee, pain, patella up, knee extension obstacle, unable to walk. Because the injury of the knee extension device is usually caused by the sudden flexion of the knee joint and the sudden violent contraction of the quadriceps femoris, and the patella is the fulcrum of the femoral condyle of the whole knee extension device, the injury of the knee extension device is mainly patellar fracture, while the rupture of the quadriceps femoris tendon and patellar tendon is relatively rare.
The typical clinical manifestations of post-traumatic patients are: knee extension disorder, tenderness and hematocele at the fracture, discontinuous emptiness of patellar tendon, and patella upward. The patient had an obvious history of trauma. Immediately after injury, he felt pain and swelling in the affected area, obvious local tenderness, inability to straighten the knee joint, limited movement and inability to walk on the ground. After fracture, the patella moved upward due to the violent contraction of quadriceps femoris, and the gap between the broken ends could reach 2-5cm. Palpation examination showed that the broken ends felt empty and sore.
matters needing attention
Because the injury of knee extension device is usually caused by the sudden flexion of knee joint, the sudden violent contraction of quadriceps femoris and sharp cutting injury, and the patella is the fulcrum of the femoral condyle of the whole knee extension device at this time, the injury of knee extension device is mainly patellar fracture, while the rupture of quadriceps femoris tendon and patellar tendon is relatively rare. Therefore, pay attention to calm down in case of trouble, avoid emotional conflict, leading to the disease. Secondly, early detection, early diagnosis and early treatment are also of great significance for indirect prevention of the disease.
