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

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.
