Robotic Anterior Bikini Hip Replacement Surgery 

Robotic Anterior Bikini Hip Replacement - CORIOGRAPHY

CORIOGRAPHY The Next Generation of Precision Hip Replacement Surgery

Hip replacement surgery has evolved dramatically over the past decade. By combining the Anterior Bikini Hip Replacement approach with the latest CORIOGRAPHY Robotic Navigation Technology and Planning, we can achieve exceptional precision in implant positioning while preserving muscles and helping patients return to an active lifestyle sooner.

This advanced technology allows every hip replacement to be individually planned and accurately guided during surgery, rather than relying on visual estimation alone.

Our goal is simple:

A natural feeling hip, accurate implant positioning, improved stability and a faster recovery with early return to activities patients enjoy doing.

What is CORIOGRAPHY Robotic Hip Replacement?

CORIOGRAPHY is an advanced computer-assisted navigation platform developed to improve the accuracy of implant positioning in total hip replacement surgery by Smith and Nephew. Guiding the surgeon to perform multiple tasks during surgery including assistance in performing accurate neck resections of the femur and position the implant (Cup) in the desired position based on Pre Planning using the coriography software based on the CT scans and special Xrays that were performed.

Unlike conventional hip replacement, where implant positioning relies primarily on surgical experience and anatomical landmarks, CORIOGRAPHY continuously tracks your anatomy throughout the operation using sophisticated infrared navigation technology when used.

This provides your surgeon with real-time information regarding:

  • Hip anatomy
  • Pelvic position
  • Cup inclination
  • Cup anteversion
  • Leg length
  • Hip offset
  • Implant positioning

The system acts as an intelligent guidance platform, helping your surgeon reproduce the personalised surgical plan with remarkable accuracy throughout the procedure although planning and implant sizing/positioning is most important.

Why Accuracy Matters

A successful hip replacement depends on much more than simply replacing the arthritic joint.

Precise positioning of every implant can influence:

  • Hip stability
  • Range of motion
  • Walking pattern
  • Leg length equality
  • Implant longevity
  • Risk of dislocation
  • Wear of the bearing surfaces
  • Overall patient satisfaction

Even small differences in implant orientation may affect long-term function.

Robotic CORIOGRAPHY technology allows continuous verification of implant position during surgery to help optimise these important factors.

Robotic Personalised Surgical Planning

Every patient’s hip anatomy is different.

Prior to surgery, specialised digital templating software is used to carefully analyse:

  • Hip anatomy
  • Pelvic tilt
  • Leg length
  • Hip offset
  • Implant sizing
  • Cup orientation
  • Stem selection

This personalised surgical plan becomes the blueprint for your operation.

During surgery, CORIOGRAPHY reproduces this plan in real time while allowing adjustments based on your individual anatomy.

Real-Time Robotic Navigation During Surgery when performed

During the operation, specialised optical trackers are temporarily attached to the pelvis and femur.

These allow the navigation system to continuously monitor:

  • Hip movement
  • Pelvic position
  • Implant orientation
  • Leg length changes
  • Hip offset restoration

The surgeon receives live feedback throughout every stage of surgery.

This provides a level of precision that cannot be achieved using conventional techniques alone.

Optimising Leg Length

One of the most common concerns after hip replacement is leg length.

CORIOGRAPHY measures leg length continuously throughout surgery.

The navigation system compares your hip before and after implantation, allowing accurate restoration of:

  • Leg length
  • Hip offset
  • Biomechanics

This helps reduce the likelihood of noticeable leg length differences while restoring natural hip function.

Combined with the Anterior Bikini Hip Replacement

Our preferred surgical technique is the Direct Anterior Approach, often called the Bikini Hip Replacement.

This modern muscle-sparing approach is performed through a cosmetic skin crease incision at the front of the hip.

Benefits may include:

  • No muscle detachment
  • Smaller cosmetic incision
  • Reduced post-operative pain
  • Earlier walking
  • Reduced dislocation risk
  • Faster functional recovery
  • Improved early mobility
  • Shorter hospital stay for many patients

By combining the Anterior Bikini Approach with CORIOGRAPHY navigation, patients benefit from both minimally invasive surgery and advanced precision technology.

Potential Benefits of CORIOGRAPHY Navigation Planning.

Potential advantages include:

  • Highly accurate implant positioning
  • Personalised surgery for each patient
  • Improved restoration of hip biomechanics
  • Accurate leg length assessment
  • Restoration of hip offset
  • Improved implant alignment
  • Real-time intraoperative decision making
  • Reduced reliance on visual estimation alone
  • Digital recording of implant position
  • Increased surgical precision

Is Robotic Hip Replacement Really Performed by a Robot?

No.

The operation is always performed by your orthopaedic surgeon.

CORIOGRAPHY does not replace surgical expertise.

Instead, it functions as an advanced navigation robotic platform that provides your surgeon with continuous real-time guidance and objective measurements throughout the operation.

Your surgeon remains in complete control of every aspect of your surgery.

Who May Benefit?

CORIOGRAPHY Robotic navigation may be appropriate for patients undergoing total hip replacement because of:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Hip avascular necrosis
  • Hip dysplasia (selected patients)
  • Post-traumatic arthritis
  • Degenerative hip disease

Your suitability will be determined following clinical examination and imaging.

Recovery After Surgery

Most patients begin walking on the day of surgery or the following morning.

Our enhanced recovery programme focuses on:

  • Early mobilisation
  • Pain control
  • Physiotherapy
  • Muscle preservation
  • Rapid return to independence

Many patients resume driving, office work and low-impact activities within several weeks, although recovery varies between individuals.

Frequently Asked Questions

Is robotic hip replacement safer?

Computer-assisted navigation provides additional information that helps optimise implant positioning and restore normal hip biomechanics. Like all surgery, outcomes also depend on patient factors, implant selection and surgical expertise.

Will I have a large scar?

The Anterior Bikini Approach uses a cosmetic skin crease incision positioned within the natural groin crease whenever appropriate.

Will the robot perform the surgery?

No. Your surgeon performs the entire operation while using CORIOGRAPHY as an advanced navigation system for real-time guidance.

Does robotic surgery reduce recovery time?

The combination of muscle-sparing anterior surgery and accurate implant positioning may assist with early recovery, although recovery differs between patients.

How long does a robotic hip replacement last?

Modern hip replacements commonly function well for 20 years or longer. Longevity depends on patient activity, implant type, bone quality, body weight and surgical technique.
