The lesions of human knee joint are relatively simple, and knee replacement surgery generally addresses three kinds of diseases most of all. The first is osteoarthritis, the second is rheumatoid arthritis, and the third is necrosis of the femur or tibial plateau around the bone-knee joint. Often when all three of these diseases progress to a certain point, artificial knee replacement surgery is needed to improve the function of the knee.
What are the methods of artificial knee replacement surgery? These four are the most common
As artificial materials and medical technology continue to evolve, so do surgical methods for artificial knee joints. Knee replacement is usually referred to as a surface replacement of the knee, but nowadays for doctors, it usually means all three tibial sides. If the lesion is on one tibial side, a more minimally invasive unicondylar replacement can now be used. In addition, if the knee is on one tibial side and the approach is extra-articular, an osteotomy can be used, which is both a solution to the patient's pain after the surgery and more minimally invasive.
Doctors often use osteotomy, unicondylar replacement, surface replacement and other methods according to the patient's condition. In addition, simple patellofemoral joint replacement can also be performed, mainly based on the patient's condition to choose a more appropriate method to obtain better function with less trauma.
