Posterior Hip Replacement

What is a Posterior Hip Replacement?

A posterior hip replacement is a total hip replacement performed through an approach at the back of the hip. It is one of the most widely used and well-established approaches for hip replacement, providing excellent access to the joint. As with other approaches, the damaged ball and socket of the hip are replaced with prosthetic components; the difference lies in the path used to reach the joint. The posterior approach has a long track record and remains a reliable, versatile option suitable for a wide range of patients, including more complex cases.

How it Differs from Other Approaches

The main approaches to hip replacement differ in where the joint is accessed:

• Posterior: from the back of the hip, providing excellent and versatile access to the joint.
• Lateral: from the side, through or between the muscles on the outside of the hip.
• Anterior: from the front, working between the muscles (muscle-sparing).

Each approach has its own advantages and considerations. The posterior approach is valued for its excellent visualisation and versatility, including in complex hips. The most appropriate approach for you depends on individual factors and will be discussed at your consultation.

Advantages

The posterior approach offers:

• Excellent access to and visualisation of the hip joint
• Versatility, including suitability for complex cases and revision surgery
• A long and well-established track record

Good outcomes in hip replacement depend on many factors including surgical experience, patient selection, implant choice, and rehabilitation, rather than the approach alone.

The Procedure

The procedure replaces the damaged hip joint with prosthetic components — a stem and ball replacing the femoral head, and a cup and liner resurfacing the socket. Surgery is performed under spinal or general anaesthesia and typically takes one to two hours. Imaging guidance may be used during the procedure to assist with accurate implant positioning.

Recovery

Most patients are walking with assistance on the day of surgery or the morning after. With the posterior approach, certain hip positions are typically avoided in the early recovery period to protect the healing tissues and reduce the risk of dislocation; your team will give you specific guidance on this. A structured rehabilitation programme is important, and your recovery plan will be tailored to your progress.

Risks and Complications

As with any major surgery, posterior hip replacement carries risks, including:

• Infection
• Blood clots (deep vein thrombosis or pulmonary embolism)
• Bleeding
• Dislocation of the prosthesis
• Leg length inequality
• Fracture during surgery
• Injury to adjacent nerves or blood vessels
• Implant loosening or wear over time

All relevant risks will be discussed in detail at your consultation.

Frequently Asked Questions

Is the posterior approach outdated?

No. The posterior approach is one of the most widely used and reliable approaches to hip replacement, with a long track record. It provides excellent access and is versatile across a wide range of cases, including complex ones.

Will I have movement restrictions afterwards?

With the posterior approach, certain hip positions are typically avoided in the early recovery period to protect healing and reduce the risk of dislocation. Your surgeon and physiotherapist will give you clear, specific guidance.

How do I know which approach is right for me?

The choice between approaches depends on individual factors such as your anatomy, the complexity of your hip, and other considerations. The most appropriate option for you will be discussed at your consultation.
