Background
Knee replacement is the replacement and reconstruction of diseased or injured articular surfaces with artificial biomaterials aimed at removing the lesions to relieve symptoms, eliminate pain, restore and improve joint function and improve quality of life. Modern artificial knee joint replacement surgery begins in the last 60 th century and becomes an ideal and effective treatment scheme for treating advanced joint diseases through continuous development of half a century. In recent years, with the development of scientific technology, the knee joint replacement is greatly improved and enhanced from the surgical technology to the prosthesis design concept, and is accepted by more and more doctors and patients.
An important purpose of artificial knee joint replacement is to reconstruct and recover the lower limb force line, which is easy to cause the limited knee joint movement and the pain in front of the knee due to poor alignment; prosthesis instability, loosening and wear; patellofemoral joint dysfunction, and the like. Currently, lateral femoral osteotomies of knee surgery are used by most surgeons because of the greater accuracy of femoral intramedullary positioning for guiding distal femoral osteotomies. The femur intramedullary positioning is to determine the femur valgus angle by preoperatively observing the X-ray film of the leg of a patient, determine the external rotation angle by taking the condylar passing line and the front and back axes as references in the operation, and observe whether the femur force line is accurate by using the force line measuring rod.
And tibial osteotomies are mostly performed by means of extramedullary positioning. Because the extramedullary location carries out the line of force through the locating lever and to the line, do not have the damage to the shin bone, be fit for most patients and use. Intramedullary location is to squeeze the intramedullary location pole into the inside of shin bone marrow cavity, damages tibial structure, may increase fat embolism and venous thromboembolism's risk, and the patient that the sclerotin is not good arouses complication such as later stage shin bone fracture easily.
