Customised Patient Matched Technology Knee Replacement

Key information:


The information provided on this website is done so as a guideline to assist you in further understanding your surgical treatment and what to expect. Each patient’s treatment plan is tailored to their conditions so your rehabilitation may be quicker or slower than other peoples.

Please contact Dr Rodda for advice should you be concerned about any aspect of your health or recovery.


Customised patient matched technology knee replacements add a new approach to preoperative planning. Using three dimensional MRI images (magnetic resonance imaging), the surgeon creates a 3D template of the knee for each patient prior to surgery. The three-dimensional images of the knee joint allow the surgeon to accurately choose the correct size for the customised implant, and plan the exact location for where the implant components will be attached.

These three-dimensional images of the knee taken during the MRI are then sent to the manufacturer of the artificial implant components to analyse. From there a cutting guide is designed from the exact specifications of the patient’s knee. The preoperative plan is then sent back to the surgeon for final approval. Once the surgeon approves the plan, the manufacturer of the artificial implant components creates the customised cutting guides for the patients knee and sends it along with the appropriate surgical tools to the surgeon for the procedure.


The benefits associated with the customised patient matched technology knee replacements include:

  • Shorter, less invasive surgery
  • A more custom fit
  • Improved balance and stability of ligaments


As with any major surgery, possible risks and complications are associated. The risks of customised patient matched technology knee replacement surgery include:

  • Knee stiffness
  • Infection
  • Blood clots (deep vein thrombosis)
  • Nerve and blood vessel damage
  • Ligament injuries
  • Loosening of the customised implants


Who is a suitable candidate for customised patient matched technology knee replacement surgery?
Patients who find difficulty in performing simple activities such as walking or climbing stairs because of severe arthritic knee pain. It is a safe and effective procedure to relieve pain, correct leg deformity, and help patients resume their normal activities of daily living.

What will my recovery include?
Rehabilitation begins immediately following the surgery. Dr Rodda will prescribe specific exercises to strengthen the leg and restore knee mobility. Patients will be able to walk with the aid of crutches or a walker.  Patients will also be provided with a home exercise program to strengthen the thigh and calf muscles.

When can I return to driving?
Patients can typically return to driving about six weeks after the operation.
