Hip revision is a great surgery as long as there’s an underlying cause for doing the revision. Most hip replacements last for 15 to 20 years. Usually there is bone loss and the implants have loosened making the bone change around the implant and the standard polyethylene plastic used wears out. Sometimes a revision is necessary if the hip starts to dislocate or an infection has developed. If all of the criterias are met, we go ahead and replace the parts that are worn out. Surgery can vary anywhere from an 1 to 3 hours depending on the parts that have to be removed and trimmed. The hospital stay is longer than a standard hip surgery and can be 3 or 4 days. Recovery and therapy can be twice as long also. The key to a successful hip revision, is to have a known reason why the patient is feeling pain. Hip pain alone without understanding why the pain is there is not successful. Pain can be due to the wear of the plastic, something loose within the hip and/or leg length discrepancy. When there is a known source from the pain the surgery is successful. It is always recommend that hip revisions are done by surgeons that have had experience and special training. Dr. Kang does approximately 100 revisions every year and has had hundreds of hours of training during his fellowship. Dr. Kang continually educates himself at conferences and lectures with surgeons all over the US that specialize in hip and knee revisions. He is always looking at new technology and implants when they are available.
