Hip replacement surgery (THR) , also known as total hip arthroplasty, is a surgical procedure that involves replacing a damaged or diseased hip joint with an artificial joint, called a prosthesis. The hip joint is a ball-and-socket joint where the head of the femur (thigh bone) fits into the acetabulum (socket) of the pelvis.
Hip replacement surgery is typically recommended for individuals with severe hip pain and disability caused by conditions such as osteoarthritis, rheumatoid arthritis, avascular necrosis, hip fractures, or other hip joint disorders.
The surgery aims to relieve pain, improve mobility, and enhance the overall quality of life for the patient. During the procedure, the surgeon makes an incision along the side of the hip to access the joint. The damaged cartilage and bone are then removed, and the femoral head is replaced with a metal or ceramic ball component.
The acetabulum is prepared by removing the damaged surface and lining it with a metal socket component. These components are usually fixed in place using a combination of bone cement or by relying on the natural bone's ability to grow and bond with the implant over time.
The type of prosthesis used can vary depending on factors such as the patient's age, activity level, and the surgeon's preference. After the surgery, the patient undergoes a period of rehabilitation to regain strength and mobility.
Physical therapy exercises and techniques are employed to help the patient gradually resume normal activities and optimise the function of the new hip joint.
However, it is important for patients to follow their surgeon's instructions for postoperative care and rehabilitation to achieve the best possible outcome.
