(AMIS) Anterior Approach Total Hip Replacement
A minimally invasive, muscle-sparing technique for hip replacement
The anterior approach is one of several surgical techniques used to access the hip joint during total hip replacement. In this approach, the joint is reached from the front of the body, rather than from the side or back.
This technique is often described as muscle-sparing, as it works between natural tissue planes rather than detaching muscles from the bone. The aim is to allow access to the hip joint while preserving surrounding soft tissues.
The anterior approach is one of three commonly used techniques for hip replacement, alongside the posterior and lateral (anterolateral) approaches. Each provides a different pathway to the joint, and the most appropriate option depends on factors such as your anatomy, the condition affecting your hip, and your overall health.
Dr Scott Tulloch uses contemporary surgical techniques and will recommend the most appropriate approach following a thorough clinical assessment, ensuring your treatment plan is tailored to your individual needs.

How the Anterior Approach Accesses the Hip Joint
During an anterior approach hip replacement, the hip joint is accessed from the front of the hip by working between natural muscle planes. This allows Dr Tulloch to reach the joint without detaching major muscles from the bone. Once the joint is accessed, the damaged surfaces of the hip are carefully removed and replaced with prosthetic components designed to recreate the natural ball-and-socket movement of the joint.
Because this approach works between muscles rather than detaching them, it is often described as a muscle-sparing technique. In selected patients, this may support earlier movement following surgery, although recovery can vary depending on individual factors.
How the Anterior Approach Differs from Other Hip Replacement Approaches
There are several surgical approaches used to perform hip replacement, each providing a different pathway to the hip joint. The most appropriate approach is selected based on your individual anatomy, the condition affecting your hip, and surgical planning.
Posterior approach: In the posterior approach, the hip joint is accessed from the back. This is a widely used technique and provides excellent visualisation of the joint for implant placement.
Lateral (anterolateral) approach: The lateral approach accesses the hip from the side. This may involve partial detachment of the hip abductor muscles to allow access to the joint.
Anterior approach: The anterior approach accesses the joint from the front of the hip, working between natural muscle planes rather than detaching them. In selected patients, this may support earlier movement following surgery.
Each approach has its own advantages and considerations. Dr Scott Tulloch will recommend the most appropriate technique based on a thorough assessment and your individual needs.
Anterior Approach Surgical Planning and Technique
Careful planning is an important part of anterior hip replacement surgery. Prior to your procedure, Dr Scott Tulloch performs a thorough clinical assessment and reviews detailed imaging to understand your hip anatomy and the condition affecting your joint.
This assessment typically includes:
- Your symptoms and how they affect your mobility and daily activities
- The shape and alignment of your hip joint
- X-rays and, in some cases, additional imaging
- Bone quality and the extent of joint damage
- Any previous treatments or surgery involving the hip
Where appropriate, patient-specific surgical planning may be used. This involves analysing imaging of your hip joint to help guide implant positioning and component alignment during surgery. By carefully assessing your individual anatomy, the surgical approach and implant positioning can be planned to support joint stability, movement and long-term function.
During surgery, the incision is made at the front of the hip to allow access to the joint using the anterior approach. The position and orientation of the incision can vary between patients. In some cases, a vertical incision is used, while in others the incision may be placed along the natural crease of the groin, sometimes referred to as a “bikini-line” incision.
The choice of incision depends on factors such as your anatomy, body shape and overall surgical plan. Both approaches allow safe access to the hip joint using the anterior technique.
What to Expect after Anterior Approach Total Hip Replacement Surgery
Immediate Post-operative Care:
- Patients may begin walking with assistance within 24 hours.
- Pain is managed with prescribed medications.
Use of Assistive Devices:
- Crutches or a walker may be used temporarily for support.
Discharge Instructions:
- Most patients are discharged within 1–3 days.
- Instructions on wound care, activity restrictions, and follow-up visits will be provided.
Timelines for Recovery Milestones:
- Patients may resume light activities within 4–6 weeks.
- Most individuals return to normal routines within 3–6 months.
Role of Physiotherapy:
- A personalised physiotherapy program helps strengthen muscles, restore mobility, and prevent stiffness.
Restrictions During Recovery:
- Patients should avoid high-impact activities and heavy lifting for several weeks.
- Adhering to weight-bearing and movement restrictions is essential
Is the Anterior Approach Suitable for Everyone?
The anterior approach is not suitable for every patient. The most appropriate surgical technique depends on a range of individual factors and is carefully considered as part of your overall treatment plan.
Factors that may influence the choice of approach include:
- Body shape and soft tissue anatomy
- The severity of hip arthritis or joint damage
- Bone structure and alignment
- Any previous hip surgery
- Your overall health and mobility
For this reason, the decision regarding surgical approach is made on a case-by-case basis. During your consultation, Dr Scott Tulloch will assess your symptoms, review your imaging and discuss both surgical and non-surgical treatment options, including whether the anterior approach may be appropriate for your individual circumstances.
Long-term Outcomes following Anterior Approach Surgery
Expected Improvements:
- Significant pain relief and enhanced mobility are often achieved.
- Improved quality of life, allowing for resumption of daily activities.
Maintenance of Results:
- Staying active, maintaining a healthy weight, and attending follow-up appointments are essential for long-term success.
Lifespan of Implants:
- Modern hip implants are designed to last 15–20 years or longer, depending on factors such as activity level and overall health.
If hip pain and mobility issues are affecting your quality of life, AMIS total hip replacement may be an effective option. To learn more, schedule an appointment with Dr Scott Tulloch.
