Total Hip Replacement

What is a total hip replacement?

The worn part of your hip joint is replaced with an artificial joint made of surgical quality stainless steel, a metal alloy or ceramic. A plastic (polyethylene) liner is usually used. It is also called total hip arthroplasty.
Some implants can be used with orthopaedic cement; others have a special coating that binds with the bone instead. Your surgeon will help choose the most appropriate type of hip replacement for you.

The combination of ceramic or metal and plastic means the new joint has low friction, wears very slowly and moves easily with your weight on it.

Why Would Someone Need a Hip Replacement?

Common reasons include osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, avascular necrosis, or hip fractures that lead to chronic pain and loss of function.

When Do I Need a Hip Replacement?

• When you have progressive pain which at times is severe and disabling that makes it difficult to carry out normal daily activities and may disturb your sleep at night
• When you cannot walk very far and you may have to use a stick. Stairs can be very difficult.
• When your hip is very stiff that makes it hard to function as normal.

The main reason for recommending a hip replacement is pain or loss of function.

The aim of the hip replacement is to relieve the pain from your hip and to enable you to carry out your normal activities more comfortably. 

What Type of Hip Implant?

There are three different types of material used in hip replacement surgery:

• Metal (Stainless Steel, Titanium, CoCr alloy)
• Ceramic
• Polyethylene

The best combination of materials used for your implant will be determined by your surgeon during your consultation.

What Type of Hip Replacement Implant is Best?

There is no straight answer to this. While ceramic ball implants are famously durable, advancements with polyethylene mean this material is now just as long-lasting.

The material used in hip replacement surgeries is determined by a number of factors. These include:

• Age and health
• Activity level
• Bone quality

There are different materials and designs. Your surgeon will choose based on your age, activity level, and anatomy. Common materials include metal, ceramic, and high-grade plastic components.

How is The Operation Done?

A hip replacement is a major operation and usually takes approximately one hour. The operation will be done under spinal (epidural) anaesthetic or general anaesthetic (where you are put completely to sleep) and the existing hip joint is replaced:

• The surgery is usually carried out through a small incision over the side of the hip
• The upper part of the thigh bone is removed
• The natural hollow in the pelvis, called the acetabulum, is hollowed out further and either Titanium or a plastic cup is fitted into the hollow. A short, metal stem, with a smooth ball on its upper end to fit into the socket, is secured into the canal of the thigh bone
• The plastic cup and the metal stem may be either press-fit or may be fixed with acrylic cement
• The layers of soft tissue, muscle and skin are stitched and clipped back together

How Do I Prepare for Hip Surgery?

Preparation for hip replacement includes:

• Medical evaluations and imaging (X-rays, MRIs)
• Pre-operative physical therapy to strengthen muscles around the hip
• Adjusting medications and stopping blood thinners as recommended by your surgeon
• Arranging for help with daily activities during recovery

What Happens on the Day of Surgery?

• You’ll be asked not to eat for 6 hours before surgery, but you may drink water up to 2 hours before.
• You’ll meet your surgeon and anaesthetist beforehand to discuss the procedure and your anaesthetic options—typically a spinal or general anaesthetic.
• Surgery lasts about one hour. A local anaesthetic "block" is also applied to the hip area to keep you comfortable after surgery.
• You’ll be monitored in recovery before returning to the ward.

Pain Management and Early Mobilisation

As the local anaesthetic wears off, it’s important to start pain relief early to stay comfortable. Mr Tumia’s practice adapts an enhanced recovery programme, aiming to get patients moving within hours after surgery.

You’ll typically stand and walk with crutches either the same day or the morning after surgery, bearing full weight on the operated leg.

Will I Need Physio Therapy After Surgery?

Yes, physical therapy is a critical part of recovery. It begins soon after surgery to help regain strength, flexibility, and mobility. Your therapist will design a program tailored to your needs and recovery progress.

What Is the Recovery Timeline?

Recovery varies between individuals, but most patients:

• Return to daily activities and sedentary work within 6-12 weeks

• Resume low impact sports and exercise after 8-12 weeks, depending on the surgeon's recommendations and your healing progress

Activities to Avoid After Surgery

You should:

• Bear weight as tolerated
• Avoid high-impact or twisting sports (e.g. running, tennis, jumping)
• Your team will guide you on safe movements and provide physiotherapy support.

When Can I Return to Work?

• Office-based or remote workers may return in 6 weeks
• Physically demanding jobs may require up to 12 weeks

When Can I Drive?

You can usually drive after 6 weeks, once you can perform an emergency stop. It’s wise to have another licensed driver accompany you the first few times.

When Can I Exercise Again?

Gentle exercise can usually begin after 6 to 12 weeks. Avoid repetitive impact activities for at least 3 months. Your recovery plan will be tailored to your fitness level and goals.

How Long Does Total Hip Replacement Last?

Modern hip replacements can last 15–20 years or more. Longevity depends on factors such as activity level, implant type, weight, and overall health.

What Is the Success Rate of Hip Total Hip Replacement?

The success rate of hip replacement is high, with 90–95% of patients reporting significant pain relief and improved hip function. Studies show that most patients experience a return to normal or near-normal activities after recovery.

What are the risks of hip resurfacing surgery?

• Infection
• Blood clots
• Implant loosening or wear
• fracture or dislocation
• Nerve or blood vessel injury
• leg length discrepancy
