The artificial hip joint (Hip Prosthesis) is used as an effective replacement for the damaged joint in cases where there is severe joint destruction, advanced arthritis, specific fractures, or chronic and debilitating pain. In the cemented method, the prosthesis components are placed inside the bone using special bone cement and provide sufficient stability immediately after surgery. This technique is particularly suitable for elderly patients or individuals with low bone quality and osteoporosis, as the bone does not have sufficient ability for natural prosthesis fixation.
The main advantage of this method is immediate fixation, reduction of initial pain, and the possibility of earlier patient mobilization. The cemented hip joint consists of various components including Stem, Head, and Cup.
This method has been used for many years as a reliable solution in hip surgeries.

In the Cementless Hip Joint Replacement (Uncemented Hip Prosthesis) method, the prosthesis is placed inside the bone without the use of cement, and its surface is designed in such a way that the bone grows onto the surface of the prosthesis over time and stabilizes it naturally and securely. This method is usually recommended for younger patients or those with strong bones and good bone density.
In the cementless method, the prosthesis relies on its precise shape and special surface design; without using any adhesive, it is firmly placed in the bone canal and is held in place by the natural pressure of the bone. The main components of this type of joint include the Stem, Head, and a cup with a porous surface.
The important advantage of this technique is longer durability, more natural fixation, and better long-term performance of the joint. Although more caution is required in weight-bearing during the first few weeks, the final result is usually very strong and stable fixation of the prosthesis.

Hip revision surgery is performed when the previous hip prosthesis has lost its function due to loosening, wear, periprosthetic fracture, infection, or fatigue, and there is a need for complete or partial replacement of its components. In this surgery, long stems are used to create greater stability in deeper and healthier areas of the bone, because in revision procedures, part of the bone is usually resorbed or weakened and requires more extensive mechanical support.
Long stem prostheses, with their special design, are placed in the more distal parts of the femoral bone canal and provide the ability to create high stability even when the previous bone is damaged or destroyed.
The components of this system include: Long Stem, Long Stem Body, Head, and Cup.
The main advantage of revision surgery with long stem is restoring joint stability, reducing pain, and increasing the longevity of the new prosthesis. This method is one of the most important and precise hip surgeries and is used for patients who require complete correction or reinforcement of the previous prosthesis.

The acetabular cup is the main component of the acetabular system in total hip replacement surgery, which is placed inside the acetabulum cavity of the pelvis. This piece acts as the base structure and is responsible for bearing and transferring the forces applied from the hip joint to the pelvic bone. The cup is designed to provide the highest compatibility with the natural anatomy of the pelvis and to enable stable and precise placement at the surgical site.
The acetabular cup plays a significant role in creating overall joint stability, maintaining the proper center of rotation, and preventing dislocation or instability of the joint. Its design also ensures uniform pressure distribution on the contact surface with the bone and provides the necessary conditions for long-term and reliable joint performance.
The acetabular liner is the piece that is placed inside the acetabular cup and forms the final articular surface of the hip joint. This component is in direct contact with the femoral head, and its main role is to create smooth, controlled, and stable joint movement. The liner is designed to reduce friction and mechanical stresses and to simulate the natural movement of the hip joint.
