Frequently-asked questions about hip replacement surgery

Hip replacement surgery is a common orthopaedic procedure used to relieve pain and restore mobility in patients with severe hip joint damage. Whether caused by osteoarthritis, injury or another condition, this surgery can significantly improve quality of life. Below are answers to some of the most frequently-asked questions about the procedure.

When is hip replacement surgery needed?

Hip replacement is usually recommended when:

• Pain interferes with daily activities, such as walking or climbing stairs.
• Symptoms persist despite non-surgical treatments like physiotherapy or medication.
• Joint damage is visible on X-rays or scans.
• There is reduced mobility or stiffness in the hip.

The most common reason is advanced osteoarthritis, but other causes include rheumatoid arthritis, fractures or avascular necrosis.

What does the surgery involve?

Damaged parts of the hip joint are removed and replaced with artificial components. These may be metal, ceramic or plastic. There are different surgical approaches, and these include traditional and minimally invasive techniques. Which one is undertaken depends on individual anatomy and surgeon preference.

How long does the procedure take and what is the hospital stay?

Surgery usually takes one to two hours. Most patients stay in hospital for one to three days, depending on their recovery and overall health. Enhanced recovery programmes may help shorten the stay while maintaining safety and comfort.

What are the risks of hip replacement surgery?

While complications are rare, they can include:

• Blood clots in the leg (deep vein thrombosis)
• Infection
• Dislocation of the new joint
• Difference in leg length
• Wear or loosening of the implant over time

These risks are minimised through careful surgical planning, preventive measures and post-operative care.

What can I expect after surgery?

Recovery varies, but most people can:

• Start walking with support on the same or next day
• Resume light daily activities within a few weeks
• Return to driving in 4 to 6 weeks
• Achieve full recovery within 3 to 6 months

Physiotherapy is essential to build strength and regain movement.

What helps to improve recovery?

• Following physiotherapy advice
• Taking prescribed medication
• Attending follow-up appointments
• Maintaining a healthy weight
• Avoiding high-impact activities during early healing

Will I need a second hip replacement in the future?

Hip replacements are designed to last 15–20 years or more, depending on the type of implant, your activity level and weight. Younger or more active patients may eventually need revision surgery later in life.

Are there alternatives to hip replacement?

If symptoms are not yet severe, non-surgical options may help, including:

• Pain relief medication
• Injections (such as corticosteroids)
• Exercise programmes to strengthen muscles
• Lifestyle modifications

However, when the joint is significantly damaged, surgery may be the most effective solution.

Will the new hip feel normal?

Most people experience a significant reduction in pain and improved mobility. While the artificial joint may not feel exactly like the natural one, it should allow you to return to many normal activities without discomfort.
