What is Hip Resurfacing?

Hip resurfacing surgery is a bone-conserving alternative to total hip replacement that preserves significantly more of the patient's natural femoral bone. Instead of removing the entire femoral head, the surgeon resurfaces it with a smooth metal cap while replacing the damaged hip socket with a metal cup. This procedure is particularly suitable for younger, active patients who wish to maintain higher activity levels and preserve bone stock for potential future revisions. If you're unsure whether resurfacing or a total hip replacement is right for you, Dr. Krunal Donda offers specialist assessment and shared decision-making at Shivaan Hospital.

Understanding Your Hip Joint

The hip is a ball-and-socket joint where the femoral head (ball) fits into the acetabulum (socket) of the pelvis. The joint surfaces are covered with smooth cartilage that allows frictionless movement. In hip osteoarthritis or avascular necrosis, this cartilage wears away, causing pain and stiffness. Hip resurfacing addresses this by capping the damaged femoral head with metal and replacing the worn socket.

Key Components
Femoral head: The ball-shaped top of the thighbone that's resurfaced rather than removed.
Acetabulum: The hip socket that receives a metal cup replacement.
Metal cap: Smooth cobalt-chrome covering placed over the prepared femoral head.
Acetabular cup: Metal socket component that articulates with the femoral cap.

Who Benefits from Hip Resurfacing?

Hip resurfacing candidates are typically younger, active patients with good bone quality who want to preserve bone stock and maintain high activity levels. Proper patient selection is crucial for optimal outcomes and implant longevity. Our team includes specialist physiotherapy — learn about our physiotherapy (pre & post-op) programs to support recovery.

  • Age factor: Generally suitable for patients under 60 years with adequate bone density and quality.
  • Activity level: Active individuals seeking to return to sports, recreational activities, or physically demanding work.
  • Bone quality: Good bone stock without significant osteoporosis or cysts in the femoral head.
  • Diagnosis: Primary osteoarthritis or avascular necrosis with preserved femoral bone structure.

What Conditions Does Hip Resurfacing Treat?

Hip resurfacing addresses various hip conditions that cause pain and functional limitation in younger patients. The procedure is most successful when bone quality remains good despite cartilage damage.

  • Osteoarthritis: Primary hip arthritis causing cartilage loss and pain in younger, active patients.
  • Avascular necrosis: Loss of blood supply to the femoral head causing bone death and collapse.
  • Post-traumatic arthritis: Hip arthritis developing after previous hip injuries or fractures.
  • Inflammatory arthritis: Selected cases of rheumatoid or other inflammatory conditions with preserved bone.

Symptoms Indicating Need for Hip Resurfacing

Patients considering hip resurfacing surgery typically experience progressive hip pain and functional limitations despite conservative treatment. Recognizing these symptoms early allows for timely intervention.

  • Persistent hip pain: Deep groin pain that worsens with activity and weight-bearing.
  • Stiffness: Reduced range of motion affecting daily activities like putting on shoes or getting in cars.
  • Limping: Altered gait pattern due to pain or hip dysfunction.
  • Activity limitation: Inability to participate in sports, exercise, or physically demanding work.
  • Night pain: Hip discomfort disrupting sleep despite medication.

Diagnostic Assessment for Hip Resurfacing

Comprehensive evaluation combines clinical examination with advanced imaging to assess bone quality, cartilage damage, and suitability for hip resurfacing procedure. Detailed pre-operative planning ensures optimal component sizing and positioning. Our diagnostic imaging services (X-ray, CT, MRI) support this planning — see Diagnostic Imaging.

  • X-rays: Assess joint space narrowing, bone quality, cysts, and anatomical measurements.
  • MRI scan: Evaluate cartilage damage, avascular necrosis extent, and femoral head viability.
  • CT scan: Detailed bone structure assessment for precise pre-operative planning.
  • Bone density: DEXA scan to confirm adequate bone quality for resurfacing implant.

Hip Resurfacing vs Total Hip Replacement

While both procedures address hip arthritis, hip resurfacing offers distinct advantages for appropriate candidates including bone preservation, more natural biomechanics, and easier revision if needed in the future. If bone quality is suboptimal, total hip replacement remains an excellent option.

Hip Resurfacing Benefits

  • Bone preservation: Maintains femoral bone stock for future revision options.
  • Natural biomechanics: Larger femoral head preserves normal hip mechanics and range of motion.
  • Stability: Lower dislocation risk due to larger ball size.
  • Activity level: Better suited for return to high-impact activities and sports.

Total Hip Replacement

  • More bone removal from femoral head and neck.
  • Suitable for all ages and bone quality levels.
  • Multiple bearing surface options available.
  • Longer track record with extensive outcome data.

The Hip Resurfacing Procedure — What to Expect

The hip resurfacing operation is performed under general or spinal anesthesia, typically lasting 2-3 hours. The surgeon preserves the femoral head while preparing it to receive a metal cap, and replaces the damaged acetabular socket with a metal cup.

  • Surgical approach: Performed through a posterior or lateral hip incision preserving hip muscles.
  • Femoral preparation: Damaged cartilage removed and femoral head shaped to fit metal cap.
  • Component placement: Metal cap cemented onto femoral head; press-fit cup inserted into socket.
  • Metal-on-metal bearing: Smooth cobalt-chrome surfaces articulate providing low friction movement.
  • Hospital stay: Typically 2-3 days with early mobilization and physiotherapy.

Rehabilitation After Hip Resurfacing Surgery

Hip resurfacing recovery follows a structured protocol allowing progressive return to activities. Most patients achieve excellent functional outcomes with dedicated rehabilitation and gradual activity progression.

  • 1
    0-6 weeks: Protected weight-bearing with crutches, gentle range of motion exercises, wound healing.
  • 2
    6-12 weeks: Progressive weight-bearing, strengthening exercises, return to driving and light activities.
  • 3
    3-6 months: Advanced strengthening, proprioception training, return to most daily activities and low-impact sports.
  • 4
    6-12 months: Full recovery, return to high-impact activities including running, tennis, skiing with surgeon approval.

Hip Resurfacing Outcomes and Potential Risks

Modern hip resurfacing implants provide excellent pain relief and functional restoration with success rates exceeding 95% at 10 years in properly selected patients. Understanding potential risks and metal ion considerations is important for informed decision-making.

Potential Risks & Complications
Metal ion release: Metal-on-metal bearings release small amounts of cobalt and chromium ions requiring periodic blood monitoring.
Femoral neck fracture: Rare risk of fracture through the resurfaced femoral neck (1-2% of cases).
Infection: Standard surgical infection risk managed with antibiotics and sterile technique.
Component loosening: Potential for implant loosening over time requiring revision surgery.
Heterotopic ossification: Abnormal bone formation around the hip managed with preventive medications.
