It is known as (THA) Total Hip Arthroplasty. If we compare the hip joint to a ball and socket, in this surgery the defective head of the femur, which usually loses its spherical shape, is removed and a prosthesis similar to the real head is inserted in its place.

In most cases, the acetabulum loses its cartilage and the ball and socket are reconstructed together. If all stages of the operation go well and the patient does not suffer from any congenital dislocation or reoperations, he will be nearly 98% satisfied. As with all cases of joint replacement surgery, the degree of disability in daily life or progressive pain in the hip joint that non-surgical treatments and the passage of time have not been effective; the decision to have surgery is made.
