Revision hip replacement is performed for loose prosthesis, worn artificial hip joint or lost bone tissue. The surgery is also recommended when the hip is fractured, loosened due to infection or dislocated from its position. Due to these problems, patients experience severe pain and inconvenience in walking. During the surgery the previous implants are removed and the hip is reconstructed with the new implants. The revision surgery is based on specific factors for individual patient such as patient’s hip and leg bones, original prosthesis used, if the original prosthesis is cemented or not and patient’s age and health. Dr. N.K. Agarwal has wide experience in revision hip replacement with highly satisfactory results offered. The surgery offers lasting results for more than ten years.
