Total Hip Replacement (Arthroplasty)

The direct anterior approach (Anterior Minimally Invasive Surgery (AMIS)) is a minimally invasive technique that involves an incision made at the front of the hip. This method allows your surgeon to work between muscles and tissues without cutting through them, which can lead to a faster recovery, less post-operative pain, and a shorter hospital stay. This approach is particularly suitable for patients who prioritise a quick return to their normal activities. It does, however, require a high level of specialised training and extensive experience, both of which Dr Tulloch has meticulously developed through years of dedicated practice and advanced education.

The posterior approach is one of the most widely used techniques in hip replacement surgery, primarily because it provides excellent visibility and access to the hip joint. This approach has become popular due to its versatility and the familiarity surgeons have with the technique. It’s important to note however, that being widely used doesn’t always mean it’s the best option for every patient. The posterior approach involves cutting through some muscles at the back of the hip, which are then carefully reattached during the procedure. With proper rehabilitation, patients can achieve a successful recovery of hip function.

Dr Tulloch may choose this technique in specific circumstances where the benefits of enhanced visibility of the hip joint outweigh other considerations, ensuring the best possible outcome for the patient.

The SuperPATH approach (short for superior percutaneously assisted total hip replacement) is a more recent variation of the posterior technique. It is designed to minimise tissue disruption by working between muscles rather than cutting through them. This can make the approach less invasive while still allowing access to the hip joint.

Unlike the traditional posterior method, the SuperPATH technique typically avoids detaching major muscles or tendons. This muscle-sparing approach may support faster recovery, reduced pain, and a lower risk of hip dislocation in some patients. It’s important to remember, however, that no single approach is best for everyone.

Dr Tulloch may recommend the SuperPATH approach for patients where tissue preservation is a priority and the anatomy is suitable, always aiming to tailor the procedure to each individual’s needs and goals.

The lateral approach involves an incision made on the side of the hip, offering good access to the hip joint while balancing stability with the preservation of some muscle function. This approach is often selected for patients with specific anatomical considerations or those who may be at a higher risk of hip dislocation. However, it is important to note that the lateral approach involves detaching and splitting the hip abductor muscles (gluteus medius and minimus), which can sometimes result in a permanent limp due to the muscles’ inability to fully stabilise the hip after surgery. Bone growths, or ossifications, may also develop in the damaged gluteal muscles.

Although recovery times may be slightly longer compared to the anterior approach, the lateral approach remains a reliable option for a wide range of patients, particularly when other techniques may not be suitable.

Dr Tulloch does not typically use this approach for his patients, preferring other methods that better align with his goal of optimising patient outcomes and minimising post-operative complications.

The anterolateral approach to hip replacement involves accessing the joint from the front and side of the hip. This technique aims to preserve muscle while still providing good visual access to the hip joint, making it a viable option for selected patients.

The approach typically works between muscle groups rather than cutting through them, particularly the gluteus medius and minimus. By preserving these important muscles, it may help maintain hip strength and support post-operative stability.

While the anterolateral approach avoids detachment of key tendons, it can place traction on surrounding muscles and nerves. For this reason, it is less commonly used in Australia but may be considered in specific cases where the benefits outweigh these risks.
