Do I need a hip replacement?

Hip pain can significantly impact quality of life, affecting everything from walking and exercising to simple daily activities. When the pain persists despite conservative treatments, the question arises: “Do I need a hip replacement?”

This article provides an expert insight into the signs that indicate the need for a hip replacement, what the surgery involves, and what to expect in terms of recovery and long-term outcomes.

How do I know if I need a hip replacement?

If you experience persistent pain in your hip joint that doesn’t improve with rest, medication or physiotherapy, it could be time to consider surgery. Other symptoms include difficulty walking or performing daily activities, stiffness that limits your range of motion, and hip pain that disrupts your sleep.

In addition, the conditions that typically lead to hip replacement include:

• Osteoarthritis: The most common cause, osteoarthritis occurs when the cartilage cushioning the hip joint wears away.
• Rheumatoid arthritis: An autoimmune condition where the immune system mistakenly attacks the joint lining.
• Trauma or injury: Severe fractures or injuries to the hip joint can cause lasting damage, sometimes requiring surgical intervention.
• Avascular necrosis: A condition that results from a lack of blood supply to the bone, causing the bone tissue to die and the joint to deteriorate.

What imaging tests may be used to assess my hip joint?

Imaging tests provide detailed pictures of the joint, allowing your orthopaedic surgeon to evaluate the extent of damage or deterioration. The most common tests are:

• X-rays: X-rays can reveal bone spurs, joint space narrowing, and bone damage caused by arthritis.
• MRI: If further detail is needed, an MRI can provide a clearer view of the soft tissues around the joint, including cartilage, tendons and ligaments. It can also detect early signs of avascular necrosis or subtle fractures.
• CT scans: In some cases, a CT scan may be used to create a 3D view of the joint, especially if there’s uncertainty about the extent of bone damage.

Your surgeon will use the information from these imaging tests, along with your symptoms and physical examination findings, to guide treatment planning.

How is hip replacement surgery performed?

Hip replacement is a surgical procedure that replaces damaged or diseased parts of the hip joint with artificial components. These components are usually made of metal, ceramic or plastic. The new joint will mimic the natural movement of the hip joint, allowing for smoother motion.

Your surgeon will start by making an incision - either in the front, back or side of the hip - depending on the surgical approach. The damaged ball (femoral head) will be removed, along with any diseased cartilage. Your surgeon will then replace the femoral head with a prosthetic ball attached to a metal stem, which is inserted into the femur. The socket will be replaced with a durable artificial component.

Hip replacement is performed under general anaesthesia and typically takes 1-2 hours, although this can vary based on the complexity of the case and the surgical technique used. It can be performed as a traditional open surgery or using minimally invasive techniques, which may result in smaller incisions and a quicker recovery time.

What is the recovery time after a hip replacement?

The recovery period after a hip replacement varies from patient to patient. On average, you will begin walking with assistance (such as a walker or crutches) 24-48 hours post-surgery. Physiotherapy will also start early to support mobility and strength.

Most patients will return to light activities within 3-6 weeks. Pain and stiffness should gradually improve during this time. Full recovery, including regaining full strength and mobility in the hip, will then take 3-6 months.

Hip replacements are highly durable, with most lasting 15-20 years or longer, depending on your age, activity level and the type of prosthetic used. Proper care, including maintaining a healthy weight and avoiding high-impact activities, can help extend the life of the implant.
