Advances in hip replacement surgery

Recent improvements in hip replacement surgery technology and techniques have led to better outcomes, such as:

  • Reduced wear on the replacement joint, which extends the life of your implant,
  • Shorter post-operative rehabilitation, so you can resume everyday activities sooner.

Read about some of the latest techniques here -  you may wish to discuss them with your orthopaedic surgeon.

Computer assisted hip surgery

Computer assisted hip surgery

With computer-assisted hip surgery your surgeon can create a model of your hip and plan accordingly for surgery. He or she is able to correct potential misalignment during the surgery, and better visualise your anatomy – this is particularly important when minimally invasive surgical techniques are used.

What are the benefits of computer-assisted hip surgery?

The aim of computer-assisted hip surgey is to help your surgeon work more efficiently and align your implant more accurately to your unique anatomy, so you can benefit from:

  • Reduced joint wear, making your implant last longer1,2
  • Shorter rehabilitation time3
  • Smaller incision4
  • Less blood loss compared to a standard hip replacement5
  • Reduced risk of future dislocation due to correct aligment.1,2

Talk to your surgeon about the types of joint surgery appropriate for you and the risks associated with any surgery.

Minimally invasive hip surgery (MIS)

Minimally invasive hip surgery (MIS)

Over the past 25 years, minimally invasive surgery has revolutionised many fields of medicine by enabling your surgeon to perform major surgery without a large incision, potentially causing less trauma to soft tissues than traditional techniques.

MIS hip surgery is a giant step forward in hip replacement, usually resulting in a shorter hospital stay, faster recovery, and less scarring.1,2,3 

What are the benefits of minimally invasive hip surgery?

A minimally invasive hip replacement procedure still replaces the joint with a prosthesis, but requires an incision just 8-10 cm long. It does not disturb as many muscles and tendons in the hip area as traditional hip replacement surgery, which potentially means:

  • A more natural reconstruction after the prosthesis is in place, with less scarring,
  • Quicker return to normal activity, with a shorter recovery time. 1,2,3
  • Less blood loss, less time in surgery and possibly a shorter hospital stay.1,2,3 

Stryker has partnered with surgeons worldwide to develop MIS procedures, combining a wide variety of high quality hip implants with new surgical instrumentation to help surgeons get you back on your feet sooner.

Direct Anterior Approach (DAA)

Direct Anterior Approach (DAA) 

There are several surgical approaches used to perform hip replacements, and your surgeon will recommend which surgical approach is best for you.

The direct anterior approach (DAA) is a minimally invasive technique commonly used in hip replacement surgery. Continuing orthopaedic experience suggests that this procedure may offer several advantages over more traditional surgical approaches to hip replacement.1

Traditional hip replacement techniques involve operating from the side (lateral) or the back (posterior) of the hip, which requires a significant disturbance of the joint and connecting tissues and an incision approximately 20-30 cm long.

In comparison, the direct anterior approach requires an incision that is only 8 to 10cm long, and located at the front of the hip.1 In this position, the surgeon does not need to detach any of the muscles or tendons.1

Talk with your doctor if you have any questions about the direct anterior approach for total hip replacement or hip replacement in general. Your surgeon can help you decide what is best for you.

What are the benefits of Direct Anterior Approach during hip surgery?

  • Shorter stay in hospital and quicker rehabilitation2
  • Smaller incision and reduced muscle disruption, potentially enabling a shorter recovery time and less scarring1
  • Potential for less blood loss, less time in surgery, and reduced post-operative pain1, 3, 4
  • Risk of dislocation may be reduced2
  • May allow for a more natural return to normal function and activity1, 3
