Hip Replacement
Total Hip Replacement
Total hip replacement is considered to be one of the most successful operations in all of surgery.
It is a surgical procedure that involves replacing a damaged or diseased hip joint with an artificial joint, known as a prosthesis.
The aim of the surgery is to alleviate pain, improve mobility, and enhance the overall function of the hip joint.
Why would someone need a hip replacement?
There are several reasons why a patient may need a hip replacement, including:
When is the right time to have a hip replacement?
Total hip replacement is a major operation, and the decision to undergo the surgery should be carefully considered. There is not a single right answer that can decide when is the right time to have the operation, and the decision is very individual for every patient. On the whole, however, hip replacement is recommended when you have exhausted all non-operative measures (see non-operative measures) and you feel that your symptoms are affecting your day-to-day activities and quality of life.
It is important to involve your loved ones in the decision-making process as they can provide an alternative perspective on how your symptoms impact your life. Often, you may not fully recognise the extent of the hip condition when you have lived with it for an extended period. They will also play a vital role in supporting you during and after the surgery, making their involvement important.
Mr. Costin-Brown will conduct a thorough assessment of your symptoms, perform a comprehensive examination, and take the time to discuss your options, as well as the benefits and risks of surgery, as part of a “joint decision-making process” between the patient and the surgeon.
What is involved with a hip replacement?
Essentially, total hip replacement involves removing the damaged joint and replacing it with an artificial joint (prosthesis).
A cut is made on the outside of the hip and the tissues incised to expose the joint. The damaged ball (head of the femur) is removed.
The socket (acetabulum) is prepared using a series of hemispherical “reamers” to remove the damaged cartilage and bone and leave a healthy bed of bone for the new cup. The new socket (cup), which is made of titanium, is then fitted into the bone, and a plastic (highly cross-linked polyethylene) liner is then inserted inside of the new shell.
A metal stem is inserted into the thigh bone (femur) which is attached to a ball (usually made of ceramic or metal) which fits into the new socket. Afterwards, the tissues are repaired and a dressing is applied to the wound.
What type of hip replacement will I have?
The two main methods of securing the implants to bone are “uncemented” and “cemented” techniques. Uncemented implants rely on a tight fit that allows the bone to grow onto the implants over time, providing a biological fixation. Cemented implants, on the other hand, are bonded to the bone using orthopaedic cement, similar to a superglue. These approaches have different risks and benefits, and Mr Costin-Brown will determine the most suitable option for you on an individual basis.
What approach will Mr Costin-Brown use?
Mr Costin-Brown has experience performing hip replacement using all of the approaches. He currently uses the “posterior approach” which he finds to be the most reliable and best for his patients.
What anaesthetic will I have for the surgery?
Some patients may be apprehensive about being awake during the procedure, but additional sedation can be administered alongside the spinal anaesthesia to induce sleepiness and unawareness of the surgery. The anaesthetist will discuss these options with you beforehand to ensure your comfort and understanding.
What happens after surgery?
You will undergo routine blood tests and a check XR of your hip to ensure that there are no issues. You will have your vital signs (blood pressure, heart rate, etc…) monitored regularly.
When all of the above is satisfactory, you will be discharged home. Usually this is day 1 following your operation. Some patients will be suitable for discharge the same day (if you are suitable for this service, arrangements will be made in advance). Some patients, however, take longer to recover or to be safe on their crutches, and therefore stay longer. You will not be discharged before you are ready.
What precautions do I need to do after the operation?
You will be given instructions by the physiotherapy team prior to discharge about what movements to avoid to put you at risk of dislocation. In particular, avoid deep bending of your hip and also rotation. If you imagine a line down the middle of your thigh, try to avoid moving your knee inwards. When sitting down, move your legs away from each other rather than together.
