According to the data of the Swedish Prosthesis Register system, total hip prosthesis due to arthritis is numerically in front of all other prostheses.
Hip replacement surgery is a treatment for patients who have pain due to arthritis of the hip joint and whose daily activities are restricted. It is based on replacing the upper part of the thigh bone and the nest with artificial joints. It can be metal, polyethylene or ceramic.
Preoperative planning in handmade hip prosthesis is done on 2 dimensional drawings. (1) How to place the parts during surgery depends on the experience of the surgeon. Even in the reliable applications, there is a risk of dislocation, re-operation and delay in the hospital duration. (2-3)

3-dimensional anatomy of the nest can be designed with Makoplasty (Robotic Hip Replacement). Thus, the placement and position of the nest are performed as desired. Immediate changes are monitored and controlled using Haptic technology with sensors. Using these advantages of robotic hip surgery; the most important cause of post-operative dislocation risk, fit of the nest and head is idealized. The risk of inequality related to leg length is eliminated.
Studies have shown that only 47% of the nest placement can be made to the ideal site in handmade prosthesis. It is seen that the nest implants made with Makoplasty are 6 times more accurate angularly than those handmade ones. (4-5-6)
In summary, Makoplasty is a technology that is widely available to use in the hip, and provides accurate positioning of the implant. Minimally invasive can be applied.
Early movement and long implant life are targeted by preserving the soft tissue and mechanical balance of the joint.
