Hip replacement is a surgery performed to treat severe damage to the hips. During the Hip replacement surgery, the surgeon removes some damaged sections of the cartilage and bone in the hip and replaces it with metal or hard plastic parts. These replaced prosthesis or artificial joints help in decreasing the pain and enhancing the hip function. These artificial joints are fitted into the femur and pelvis, with or without the help of cement. Hip replacement is also known as hip arthroplasty. The doctors advise a hip replacement surgery if the hip interferes in the daily routine activities and if any conservative procedures have not been of much help. The most common reason for getting a hip replacement done is arthritis as arthritis causes pain, reduced motion and swelling in the joints. Hip replacement surgery helps in relieving such symptoms and improving the quality of life of the patient.
