Signature™ knee replacement system

Arthritis of the knee joint is a common cause of pain and stiffness of the knee. Patients often suffer unnecessarily for many years, whereas knee replacement surgery can provide excellent pain relief for over 20 years in the vast majority of patients.

Our Consultant Orthopaedic Surgeons Mr Tahir Mahmud and Mr. Keith Barnes can offer suitable patients Signature™ personalised knee system (suppied by Biomet). Mr Mahmud also offers TruMatch customised knee replacements.

The system provides a custom fitted knee replacement, which can lead to a reduction in the time patients are in theatre and thereby under anaesthetic.

How it works

An MRI (magnetic resonance imaging) 3D scan is used to plan the use of the Signature™ custom femoral and tibial positioning alignment guides, that enable the surgeon to create a detailed pre-operative surgery plan, tailored to the patient’s specific requirements. The personalised positioning guides are placed directly onto the femur (thigh bone) and tibia (shin bone) to allow the orthopaedic surgeon to accurately position the knee implant thereby providing a custom fit specifically to the patient’s individual requirements, regardless of age, race, size, or gender.

Femoral alignment guide and tibial alignment guide

This less invasive surgical procedure, is similar to a traditional knee replacement but without the requirement to place instruments inside the thigh and shin bone to assist with alignment and positioning. This can significantly effect the outcome of the procedure by reducing medical complications and long term loosening rates. Guides are placed on the femur and tibia, the new knee is then positioned to your anatomy.

The advantages for the patient over traditional techniques can include :

  • Optimum alignment of the knee replacement implants for each individual patient which should improve the longevity and function of the knee repalcement
  • Less invasive surgery with a more complete recovery
  • A smaller incision is usually made
  • A shorter operation and shorter hospital stay
