The text discusses total hip arthroplasty (THA) in Croatia, focusing on the anatomy and biomechanics of the hip, characteristics of THA procedures, common symptoms, and patient education for postoperative care. THA, also known as hip replacement, aims to restore mobility and alleviate pain in individuals with severe hip conditions. It describes the anatomy and explores the biomechanics of the hip joint, with a particular emphasis on the role of muscles in mobility and stability. Exercises for the hip and deep core are demonstrated to aid in preparation for surgery. Osteoarthritis remains the primary cause, affecting individuals over 60 years old. Persistent pain, stiffness, and reduced mobility are typical symptoms of osteoarthritis. THA improves the quality of life by reducing pain and enhancing functionality. Surgical advancements, including anterior and posterior approaches, contribute to better outcomes. THA has a high success rate, with an expectation that 90-95% will last 10 years, and 80- 85% will last at least 20 years. In Croatia, THA significantly contributes to improving the quality of life for patients with various hip conditions. The average recovery time for a return to normal activities with minimal discomfort is approximately 12 weeks. The importance of educating patients about postoperative expectations for easier recovery is emphasized. General precautions, such as partial weight-bearing, avoiding excessive flexion, and limiting rotations, are detailed. In conclusion, understanding the complexity of THA, including anatomical considerations, surgical approaches, and postoperative care, is crucial for both healthcare professionals and patients, ensuring successful outcomes and an improved quality of life.
