Anterior Hip Replacement
The information provided on this website is done so as a guideline to assist you in further understanding your surgical treatment and what to expect. Each patient’s treatment plan is tailored to their conditions so your rehabilitation may be quicker or slower than other peoples.
Please contact Dr Rodda for advice should you be concerned about any aspect of your health or recovery.
Dr Rodda has a special interest in Anterior Minimally Invasive Hip Replacement Surgery.
Dr Rodda’s commitment to each patient, along with his extensive knowledge, surgical experience, attention to detail and high level of patient care both pre and post operatively, makes Victorian Orthopaedic Group the surgery of choice for many patients.
Anterior minimally invasive surgery, which is also referred to as Direct Anterior Approach (DAA), is a less invasive surgical technique used to perform total hip replacements. The DAA technique involves approaching the hip joint between the two muscles at the very front of the hip, where as other techniques involve surgery from the back or side of the hip. The risk of injury to the muscles, tendons, vessels and nerves is significantly reduced using the direct anterior approach as no muscles are detached or cut during the surgery. The patient will also experience a speedier recovery due to the muscles and nerve sparing approach.
In a traditional anterior hip replacement, the patient lies in a lateral position and an incision is made on the side or back of the hip. The incision in a DAA which is approximately 6-10cm long, is either made as an oblique skin incision over the top of your hip joint, hidden in the region of your groin or bikini line (what some surgeons call a Bikini Hip Replacement) or through a short straight incision, while the patient is lying on their back. The type of incision depends on your body type and which is more suitable.
Direct anterior hip replacement surgery involves the patient lying on their back, in a lateral position, and an incision is made in the groin or bikini line area through the oblique skin over the top of your hip joint. Alternatively, the procedure will be performed through a short straight incision along the front of the thigh.
Dr Rodda will consult with you to determine the which incision type will be most suitable for your surgery.
During the operation the worn or damaged surfaces of the hip will be replaced with using artificial components, metal is most commonly used, however ceramic or plastic components may also be used depending on your individual needs.
An anterior hip replacement procedure offers the following benefits to patients:
- Faster recovery as the technique is muscle and nerve sparing
- Smaller incision (approximately 6-10cm long)
- Correct implant placement and leg length checked throughout surgery using X-rays
- Shorter hospital stay
- Less post-operative pain
- Reduced blood loss
- Less pain medication required (avoiding nausea and constipation)
- Less post-operative restrictions (such as crutches, special chair height, sleeping on side)
- Reduced risk of post-operative dislocation
- Faster return to work and regular activities.
As with any major surgery there are some risks involved. Potential disadvantages to this technique include:
- The surgeon having less visual exposure of the hip joint during surgery
- Leg length inequality
- Reduced accuracy in implant placement (particularly in larger patients)
- Overweight patients have a higher risk of infection
- The direct anterior approach is a more difficult technique to master when compared with traditional hip replacement surgery therefore overall risk may be higher.
Why should I consider DAA?
If you are a suitable candidate, the benefits of this minimally invasive surgery method are greater compared with traditional total hip replacement surgery.
Is this technique suitable for all patients?
An anterior hip replacement is suitable for most patients. Through consultation with Dr Rodda he will determine the best course of action, depending on your circumstances another surgical approach may be more suitable.
How much pain is expected?
Whilst there will still be some pain experienced post surgery, it is significantly less pain than you would experience with a traditional hip replacement.
What will my recovery period be like?
Compared to traditional hip replacement surgeries you will have a quicker recovery time and will be able to get back to an active lifestyle sooner. You will be prescribed some rehabilitation exercises by your physiotherapist when leaving the hospital. Following these exercises and their advice will ensure the best possible recovery time.
How soon can I return to driving?
Subject to recovery, rehabilitation and success of the operation, patients can generally return to driving a couple of weeks after surgery.
