Knee replacement surgery is applied to the knee joint. The knee joint is the largest and most complex joint in the body; It carries body weight and enables movement. There is a cartilage layer that facilitates movement on the joint surfaces of the bones that make up the knee joint, and there are menisci in between. In addition , the intra-articular fluid called synovial fluid reduces friction during movement.

Due to reasons such as osteoarthritis , trauma and  rheumatoid arthritis , deterioration of  the joint that makes normal movement difficult and creates pain may occur.

What is the Purpose of Knee Replacement Surgery?

The aim of knee replacement surgery is to provide the patient with a painless and mobile joint by replacing the damaged joint surfaces . In this way, it is aimed to increase the quality of life of the patient.

Knee replacement surgery can be recommended if the knee joint is damaged, especially if the knee joint is damaged, if the person has started to have difficulty in movements such as walking and climbing stairs as a result of various  arthritis  or traumas, if the knee continues to hurt even when resting, and if methods such as physical therapy are ineffective.

How is Knee Replacement Surgery Performed?

The damaged cartilage on the sides of the thigh (femur) and tibia (tibia) bones facing the knee joint and a small part of the bone underneath are removed. Instead, metal components are placed to regenerate the joint surface. The posterior articular surface of the kneecap is cut and replaced with a special plastic surface. In some surgeries, the kneecap is not touched. A specially manufactured plastic separator is placed between the metal components for ease of movement.
