Total Hip Replacement Surgery
Total Hip replacement surgery removes damaged or diseased parts of a hip joint and replaces them with new, man-made parts. The goals of this surgery are to relieve pain, help the hip joint work better and improve walking and other movements.
Total hip replacement is a safe, reliable procedure that can relieve your pain and stiffness and return you to most of the activities that you enjoy.
There are several ways for a surgeon to perform total hip replacement surgery including (but not limited to): posterior (Moore), lateral (Hardinge or Liverpool), antero-lateral (Watson-Jones), minimally invasive and The Direct Anterior (Hueter) AMIS® approaches. (Link)
Some approaches are more muscle sparing than others leading to a quicker recovery however the most important aspect of any hip surgery is to ensure that the prosthesis is implanted accurately and correctly, that the surgery is carried out in an efficient manner minimising blood loss and reducing anaesthetic time and the risk of complications is kept to a minimum.
Remember that ALL approaches if performed correctly will result in a successful pain free outcome that should last at least 20-30 years using modern day implants.
The main benefits of a successful Total Hip Replacement are:
Reduction in Hip Pain – The pain will be rapidly and dramatically reduced and usually eliminated.
Recovery of Mobility – Your hip will function with less effort, almost regaining your original mobility.
Improvement in Quality of Life – Your everyday activities and your social life will no longer be limited by pain and reduced mobility.
People with hip joint damage that causes pain and interferes with daily activities despite trying other treatments such as exercise, walking aids and medication without significant improvement may be candidates for hip replacement surgery. This will all be discussed with your surgeon at your consultation.
Anterior Total Hip Replacement Surgery
AMIS® (Anterior Minimally Invasive Surgery), also termed the Direct Anterior Approach (DAA) is a surgical technique used in total hip replacement procedures which follows an inter-muscular and inter-nervous plane to reduce the risk of injury to muscles, tendons, vessels and nerves. By respecting the nerves and because no muscles are cut this aids in rapid recovery for patients following surgery.
The procedure is performed in hospital. Your hospital stay is usually overnight but may be longer, depending on your individual circumstances. The operation will take approximately 1.5 hours.
The incision is approximately 7 -10 cm long. The incision is made over the top of your hip joint in the region of your groin. The worn surfaces of the hip are removed and the surfaces are replaced with artificial components. Metal is used for all components however the bearing surfaces may vary depending on the patients individual circumstances: metal, ceramic, or plastic.
Ligaments and tendons are preserved so it is possible following a primary joint replacement to walk with in just a few hours after surgery, fully weight-bearing on your new hip. In fact, it is something that we want you to do unless otherwise advised.
Advantages of anterior hip surgery include a reduced risk of dislocation, the ability to sit in a normal chair immediately after surgery, the ability to safely travel home by car at the time of discharge and the ability to walk with minimal assistance in the days after surgery.
For older patients, particularly those that live alone, this facilitates a rapid return to independent living. For younger patients, including manual workers this allows a more rapid return to employment.
