Pre-Op THA Modelling

This study is exploring a new way to perform hip replacement surgery, focusing on how accurately the new hip joint is positioned. When a new hip isn’t placed perfectly, it can sometimes lead to issues and even require another operation down the line. Surgeons often find it tricky to get the exact angle and position right during surgery without extra help. This research is investigating if using computer navigation, along with special real-time modelling software, can guide surgeons to place the hip joint more precisely. We believe that this technology could lead to better results, fewer complications, and happier patients compared to traditional surgery without this computer assistance. The aim is to understand how much benefit this technology offers in helping patients recover well from hip replacement surgery.

Total Hip Arthroplasty Computer-Assisted Surgery

What is this study about?

Hip replacement surgery, known medically as Total Hip Arthroplasty (THA), is a very common and usually successful operation. It's done when your hip joint is worn out or damaged, often due to conditions like arthritis. This surgery can significantly reduce pain and improve your ability to move and do everyday activities. Patients are generally very happy with the results of their hip replacement.

However, for the best and longest-lasting results, it's really important that the new artificial hip joint is put in exactly the right place and at the right angle. If it's not positioned just so, it might not work as well, could wear out faster, or in some cases, might even need another operation to fix it later on. Surgeons do their best, but it can be surprisingly hard to judge the exact position needed during surgery.

This study is looking into a new approach that uses computer technology to help surgeons. Imagine a sat-nav for your hip! This computer navigation system, combined with special software that shows a real-time model of your hip during the operation, aims to give surgeons a very precise guide. The goal is to see if this technology can help surgeons place the new hip joint more accurately, leading to even better outcomes for patients and reducing the chances of any problems down the line. We want to find out if this hi-tech help makes a real difference to your recovery and satisfaction after a hip replacement.

Key takeaways

This study compares standard hip replacement with computer-guided surgery.
The aim is to improve accuracy of hip implant placement.
Better placement may lead to better patient recovery and fewer problems.
Computer technology helps surgeons during the operation.
Taking part is voluntary and won't affect your medical care.

Who may be eligible?

To be able to take part in this study, you would need to be having your first hip replacement surgery for hip Arthritis. You should be 40 years old or older and have a Body Mass Index (BMI) of less than 40. It's also important that you are willing and able to understand what the study involves and can attend appointments and follow instructions.

You would not be able to join the study if you've had previous surgery on the hip that needs replacing, or if you've had surgery on your lower spine where metalwork was put in. We also can't include you if you have certain fixed problems with your hip or spine, like severe deformities or specific inflammatory conditions that affect your joints, or if your other hip has very limited movement.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

Are you having your first hip replacement surgery for hip arthritis?
Are you 40 years old or older?
Do you have a Body Mass Index (BMI) of less than 40?
Have you *not* had previous surgery on your hip or lower spine with metalwork?
Do you have good movement in your other hip and no severe spine problems?
Are you willing to attend follow-up appointments?

Answer every question to see your result.

What does participation involve?

If you join this study, you will either have your hip replacement surgery with traditional methods or with the help of a computer navigation system plus special modelling software. The type of surgery you receive will be decided at random, like flipping a coin. You will have your hip replacement as planned. We will then follow your progress after the operation to see how you recover and how well your new hip is working. This will likely involve follow-up appointments and assessments at various times after your surgery. The total duration that we would follow your progress will be explained in full detail by the study team.

Potential risks and benefits

The potential benefit of taking part is that the computer-guided surgery might lead to a more accurately placed hip joint, which could mean a better recovery and fewer problems in the long run. However, there's also a chance you could be in the standard surgery group. As with any surgery, there are always some risks involved, which your surgeon will explain to you. The computer-guided approach is new, so we're studying its benefits; it could introduce small, as-yet-unknown risks or no additional benefit over standard care. You are free to withdraw from the study at any time without affecting your medical care.

Common questions

What is a hip replacement?

A hip replacement is an operation to replace a damaged hip joint with an artificial one, usually to relieve pain and improve movement.

Why is implant position so important?

Precise placement of the new hip joint helps ensure it works well, lasts longer, and reduces the chance of complications.

What is computer navigation in surgery?

It's like GPS for surgery, using computer technology to guide the surgeon in placing the new hip joint more accurately.

Will I know if I'm getting the computer-guided surgery?

The study aims to compare the two methods, so you will be assigned to either the standard or computer-guided group by chance, and you will know which approach was used after your surgery.

Do I have to take part in this study?

No, taking part is completely voluntary, and your decision won't affect the care you receive for your hip.
