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.
All hip replacements if performed correctly will result in a successful pain free outcome that should last at least 20-30 years using modern day implants. Today’s hip replacements do generally last a long time but there are a number of situations in which your hip replacement may need the implants to be changed or revised and another operation is required.
Depending on the reason for the revision, on the time that has lapsed since the first operation and the technique used in that surgery, revision procedures are often more complex that the initial operation and require careful planning and surgical skill.
Pain is the primary reason for a revision and although the cause can often be clear, it isn’t always. Many hip replacement designs include a polyethylene liner inside the socket. This can wear and is one of the easier revision surgeries as only the plastic insert is replaced.
Surgery is usually performed through the same incision however this may need some extension. Many surgeons utilise an extensile surgical approach such as a posterior or anterolateral approach for revision surgery. The other option is to use an anterior approach.
This is because there is a reduced amount of bone to place the new total hip into. Extra bone may be required which is usually received from a bone bank. This allograft bone is totally safe and has been treated to eliminate any chance of disease transmission. There are also artificial bone substitutes that may be used. Revision total hip replacement generally takes longer than a standard total hip replacement and has a slightly higher complication rate. The prosthesis may also not last as long.
The benefits and risks are generally the same as for regular hip replacement surgery however because this operation is usually a more complicated procedure it often does not produce as good results. If you require revision surgery and have any concerns, please discuss these with Dr Rodda.
Because no muscles are cut, the AMIS approach can reduce post-operative pain.[1,2]
Rehabilitation typically starts on the day of your operation (or occasionally the day after), subject to your surgeon’s approval and your post-operative condition.[2,3]
Having the AMIS technique usually significantly reduces your hospital stay.[4,5]
With AMIS, the skin incision is often shorter than that used in ‘traditional’ surgery.
The AMIS technique allows you to return to daily activities in a shorter time frame.[4,6,7]
Preservation of muscles and vessels potentially reduces blood loss during surgery.[2,5]
The risk of dislocation is reduced because it is mainly linked to posterior (rear) hip structure damage, whereas the anterior approach is performed from the front of your body.[3,8]
Minimising muscle and nerve damage reduces the chances of limping.[9,10,11,12]
All surgical procedures carry risks, including those associated with anaesthesia and the operation itself. These include blood clots, infection and vascular injury.
As highly experienced surgeons, we do everything possible to minimise these risks. We’re happy to discuss potential risks of surgery – and how they are managed – during your appointment.
