Hip Arthritis & Hip Replacement
Hip arthritis is one of the most common causes of groin pain, stiffness and reduced mobility. Many patients improve with non-surgical treatment, however when pain begins to affect sleep, walking or everyday activities, hip replacement surgery can provide excellent pain relief and restore quality of life.
What is Hip Arthritis?
The hip is a ball-and-socket joint formed by the femoral head (ball) and acetabulum (socket). Both surfaces are normally covered with smooth cartilage, allowing the joint to move freely and painlessly.
Hip arthritis occurs when this cartilage gradually wears away. As the cartilage deteriorates, the bones begin to rub together, leading to pain, stiffness and reduced movement.
The most common causes include:
Osteoarthritis
Rheumatoid arthritis
Hip dysplasia
Previous hip injury
Avascular necrosis
Symptoms of Hip Arthritis
Symptoms usually develop gradually and may include:
Groin pain
Pain in the buttock or thigh
Stiffness after sitting
Difficulty walking
Difficulty putting on shoes and socks
Reduced walking distance
Night pain
Limping
Pain is usually felt in the groin but may also radiate into the thigh or knee.
Diagnosis
Hip arthritis is usually diagnosed through your history, examination and X-rays.
X-rays commonly demonstrate narrowing of the joint space, bone spurs and loss of cartilage.
Occasionally, further imaging such as MRI or CT scanning may be recommended if the diagnosis is uncertain or for surgical planning.
Non-Surgical Treatment
Many patients experience significant improvement without surgery.
Treatment options may include:
Physiotherapy
Activity modification
Weight management
Anti-inflammatory medication
Simple pain relief
Walking aids where appropriate
Corticosteroid injections
These treatments aim to reduce pain and improve function, although they do not reverse arthritis.
Hip Replacement Surgery
Hip replacement surgery involves replacing the worn ball-and-socket joint of the hip with artificial components.
The damaged cartilage and bone are removed and replaced with smooth metal, ceramic and polyethylene components designed to reduce pain, improve movement and restore function.
Modern hip replacement aims to recreate your natural hip anatomy while providing a durable, stable and comfortable joint.
When is Hip Replacement Recommended?
Hip replacement may be recommended when:
Hip pain persists despite appropriate non-surgical treatment
Pain regularly disturbs your sleep
Walking becomes increasingly difficult
Everyday activities such as dressing or climbing stairs become painful
Hip stiffness significantly limits movement
X-rays demonstrate advanced arthritis
For many patients, hip replacement provides excellent long-term pain relief and improved quality of life.
Modern Hip Replacement
Hip replacement surgery has advanced considerably over recent years.
Contemporary techniques and modern implant designs are utilised to restore hip mechanics and optimise long-term outcomes.
Treatment is tailored to each patient's anatomy, activity level and functional goals.
Recovery After Hip Replacement
Recovery varies between individuals, however most patients can expect:
Walking on the day of surgery or the following day
A short hospital stay
Early physiotherapy
Progressive strengthening
Gradual return to normal activities
Ongoing improvement for up to 12 months
Many patients notice substantial pain relief within the first few weeks following surgery.
Frequently Asked Questions
Do I need a hip replacement?
Not necessarily. Many patients manage well with physiotherapy, activity modification and medication. Hip replacement is generally recommended when arthritis significantly affects quality of life.
How long does a hip replacement last?
Modern hip replacements are designed to provide many years of reliable function.
When can I drive?
Most patients can return to driving once they are walking comfortably, have regained good control of the leg and are no longer taking strong pain medication.
Can I return to golf, walking or cycling?
Yes. Most patients return to low-impact recreational activities following rehabilitation.
