Hip Replacement Surgery

Hip osteoarthritis is a leading cause of pain and disability among adults in Australia.

At Perth Orthopaedic & Sports Medicine, Dr Daniel Meyerkort offers expert evaluation and tailored treatment plans for hip joint conditions. Whether you're exploring non-surgical options or considering a hip replacement with the CORIN OPS system, this article covers everything you need to know.

Understanding Hip Osteoarthritis & Joint Degeneration

Hip osteoarthritis results from gradual wear and tear of the cartilage that cushions the hip joint. Over time, this causes pain, stiffness, reduced mobility, and impacts quality of life. Other causes of hip damage include rheumatoid arthritis, avascular necrosis, trauma, and congenital hip dysplasia.

Non-Surgical Management of Hip Osteoarthritis

Before considering surgery, many patients benefit from a comprehensive non-surgical management plan. Dr Daniel Meyerkort supports evidence-based, patient-specific care plans, including:

1. Physiotherapy and Exercise

Targeted hip strengthening and flexibility exercises can improve joint stability and reduce symptoms. Working with a physiotherapist can delay the need for surgery.

2. Weight Management

Losing excess weight reduces stress on the hip joint and is one of the most effective non-surgical interventions.

3. Pain Management

Anti-inflammatory medications such as NSAIDs, paracetamol, and corticosteroid injections help manage pain and inflammation. In selected patients, hyaluronic acid or platelet-rich plasma (PRP) injections may provide temporary relief.

4. Activity Modification

Avoiding high-impact activities, prolonged standing, and repetitive strain on the hip joint can alleviate symptoms and prolong joint function.

5. Assistive Devices

Walking aids like canes, walkers, and shoe inserts can improve mobility and reduce stress on the hip joint.

 

Despite the benefits of non-surgical management, some patients experience progressive pain and loss of function, prompting the consideration of surgical options.

When is Hip Replacement Surgery Needed?

Hip replacement is usually recommended when conservative treatments fail to control pain or maintain mobility. Patients may find it increasingly difficult to walk, sleep, or perform daily tasks. An X-ray or MRI confirms joint degeneration, and if the damage is significant, surgery may offer lasting relief.

Total Hip Replacement: Overview

A total hip replacement involves removing the damaged bone and cartilage and replacing it with an artificial joint (prosthesis). The prosthetic hip is typically made of metal, ceramic, or polyethylene components, designed to mimic natural joint movement.

Introducing the CORIN OPS System

At Perth Orthopaedic & Sports Medicine, Dr Daniel Meyerkort uses the advanced CORIN OPS (Optimised Positioning System) for hip replacement surgery. This robotically assisted technology allows for personalised implant positioning based on each patient’s unique anatomy and functional biomechanics.

Key Benefits of the CORIN OPS System:

1. Customised Planning

CORIN OPS uses 3D CT scans and motion data to develop a patient-specific plan. This allows precise implant positioning for improved joint stability and range of motion.

2. Improved Accuracy

The system enhances surgical accuracy by ensuring optimal alignment of the prosthesis. This reduces risks of dislocation and leg length discrepancy.

3. Restored Biomechanics

By analysing the patient’s gait and joint loading before surgery, CORIN OPS optimises the restoration of normal joint mechanics, improving outcomes.

4. Faster Recovery

Enhanced precision during surgery may reduce soft tissue trauma and promote quicker post-operative rehabilitation.

5. Long-Term Outcomes

By tailoring implant positioning to the individual, CORIN OPS may reduce wear and prolong the lifespan of the implant.

Surgical Process with CORIN OPS

The procedure begins with a detailed pre-operative scan and movement assessment. The data is processed to create a 3D model and custom plan for implant placement. During surgery, Dr Meyerkort uses specialised guides or robotic tools to align the implants exactly as planned.

Risks of Hip Replacement Surgery

While total hip replacement is highly successful, all surgeries carry some risks. These include:

  • Infection

  • Bleeding

  • Blood clots

  • Dislocation of the joint

  • Leg length discrepancy

  • Loosening or wear of the implant over time

  • Nerve or vascular injury

With CORIN OPS, the risk of malalignment-related complications is reduced, but patients must still follow post-operative care and rehabilitation protocols to optimise results.

Post-Operative Recovery

Recovery from hip replacement involves a structured rehabilitation program. Patients typically:

  • Begin walking with assistance within 24 hours

  • Stay in hospital for 1–3 days

  • Engage in physiotherapy for 6–12 weeks

  • Return to most daily activities within 6 weeks

  • Achieve full recovery within 3–6 months

Patients who undergo CORIN OPS-assisted hip replacement may experience faster recovery, lower pain scores, and earlier return to functional independence.

Long-Term Benefits of Hip Replacement

When successful, hip replacement can be life-changing. Key long-term benefits include:

  • Reduced or eliminated joint pain

  • Improved mobility and quality of life

  • Return to low-impact activities like walking, cycling, and golf

  • Improved sleep and ability to perform daily tasks

Implants may last 15–25 years or longer, especially with newer technologies and precision systems like CORIN OPS.
