Osteoarthritis is the most common cause of hip pain requiring hip replacement surgery. Over time, the protective cartilage within the hip joint gradually wears down, leading to pain, stiffness and reduced movement. As the joint surfaces become damaged, everyday activities such as walking, climbing stairs or putting on shoes can become increasingly difficult.
A fracture or significant injury to the hip can damage the joint surfaces and surrounding bone. In some cases, the joint may heal with irregular surfaces or develop post-traumatic arthritis over time. When pain and loss of function persist despite treatment, hip replacement surgery may be considered to restore joint movement.
Avascular necrosis occurs when the blood supply to the femoral head (the ball of the hip joint) becomes disrupted. Without adequate blood flow, the bone tissue can weaken and collapse, leading to joint damage and pain. This condition can progress gradually and may eventually require hip replacement surgery if the joint becomes severely affected.
In some cases, a previous hip replacement may become worn, loose or develop complications over time. This can lead to pain, instability or reduced function of the joint. Revision hip replacement surgery may be recommended to replace or repair the existing implant and restore joint stability.
Hip surgery may be considered for conditions that cause ongoing pain, stiffness or loss of movement in the hip joint. Common causes include hip osteoarthritis, joint damage from previous injury, avascular necrosis and complications from a previous hip replacement. Your suitability for surgery will be assessed during your consultation.
Modern hip replacements are designed to be durable and often last 20 years or longer. Longevity varies depending on activity level, overall health, and individual factors.
Recovery time after hip replacement surgery can vary depending on the individual, the surgical approach used and your overall health. Many patients are able to begin walking with support soon after surgery and gradually return to normal daily activities over the following weeks. Your recovery plan may include physiotherapy, guided exercises and follow-up appointments to support healing and mobility.
Anterior hip replacement is performed through the front of the hip using a muscle-sparing approach, which avoids cutting major muscles around the joint. Traditional approaches access the hip from the side or back. Dr Samson will discuss which surgical approach may be most appropriate for your condition and anatomy during your consultation.
