In the world and in Croatia, there is an increase in the number of the old population, and therefore an increased increase in diseases in the elderly population, such as degenerative diseases in the hip joint. With them, there is a decrease in activities in everyday life and the quality of life. The most common outcome in the presence of a degenerative disease in the hip joint is the installation of a total endoprosthesis of the hip joint. As with any health problem, it is necessary to approach the patient individually with the surgical procedure of installing TEP of the hip joint. When choosing the type of endoprosthesis, many factors are taken into account, including the patient's age, degree of damage to the hip joint, anatomical characteristics, level of physical activity and previous illnesses. Indications for the installation of a total endoprosthesis of the hip joint are influenced by various factors such as the age of the patient, his subjective complaints, pathological changes in the joint itself and the (impossibility) of functional activities of the hip joint. One of the most common and primary indications for hip joint endoprosthesis implantation is osteoarthritis. Complications can occur during the operation and after the operation are different. One of the most common complications is luxation of the hip joint endoprosthesis. It is important to prepare the patient pre-operatively, which includes education about the problem itself, how to fix the problem, further rehabilitation and precautions that the patient should follow. It plays an important role in improving the postoperative quality of life of the patient. The role of postoperative rehabilitation after hip TEP implantation is to enable the patient to perform functional activities again in the safest, fastest and most painless way possible. Complete rehabilitation after the installation of a total endoprosthesis of the hip joint lasts from 6 to 10 weeks without the appearance of complications during rehabilitation. The quality of life after the operation has been significantly increased due to the disappearance of pain and movement restrictions, but with the constant presence of precautions that maintain the quality of life.
