Visionaire™ patient-specific knee replacement Surgery
Mr Andy Langdown, Consultant Orthopaedic Surgeon at Spire Portsmouth Hospital, is one of the first surgeons in the South of England to routinely use patient specific technology when undertaking total knee replacement surgery.
This technology allows accurate mapping of the patient’s knee, permitting increased accuracy of the surgery itself whilst at the same time reducing the invasiveness of the operation. This reduces the amount of postoperative pain and allows more rapid rehabilitation. The increased accuracy of implant positioning should also increase the lifespan of the knee replacement.
The Visionaire™ system uses an MRI scan and special x-rays to produce specific instruments for each individual patient. These instruments allow Mr Langdown to accurately reproduce the original limb alignment which replicates the patient’s own anatomy and therefore optimises the outcome of surgery.
Traditional Total Knee Replacement uses instruments placed inside the thigh and shin bone to assist with alignment and positioning. This can cause a considerable amount of bleeding and postoperative swelling. The Visionaire™ patient-matched alignment guides are placed directly on the outside of the bone, potentially allowing a less invasive procedure. The guides only fit one patient and only fit in the ideal position, thus minimising the chance of surgical error.
Mr Langdown says “This technology, combined with the Genesis 2 Knee Replacement System (which has 15 years of data to support its use), allows me to minimise the surgical insult to the patient whilst at the same time guaranteeing optimal implant positioning and implant longevity. Recovery is enhanced, pain reduced and patients are very satisfied.”
Patients may therefore benefit from reduced blood loss and complications such as swelling and fat embolism, thus minimising their stay in hospital and improving their rate of recovery.
