1989-1993
My predominant Orthopaedic interest is knee and hip replacement surgery. I have performed over 1000 medial pivot knee replacements recently and over 1000 anterior muscle-sparing approach hip replacements.
I use computer guided alignment techniques. We use CT planning for our knee and hip replacement. For example, with knee replacements patients have a scan performed locally which is then emailed to Switzerland and Switzerland then manufacture custom instruments for alignment using 3-D printers.
Accuracy of implant positioning is vital for long-term survival of both knee and hip replacement. I am happy to perform robotic surgery but I would make some comments about robot guided surgery.
Firstly there no randomised perspective studies that document improved long-term results with robot guided surgery compared to other techniques.
Secondly the surgery generally takes 20-30 minutes longer using robotic surgery. Orthopaedic infection is often directly related to the length of time of surgery and the risk of infection may be increased.
Robotic knee replacements also require pins to be inserted above and below the knee and this increases the risk of both infection and fracture. I am happy to perform robotic guided surgery if patients specifically requested it but my personal preference is patient specific instrumentation using 3-D printers.
I am a co-designer of the MPact acetabular hip replacement which is being used internationally.
I also perform knee sports surgery including ACL reconstruction. I perform hand surgery and shoulder surgery including rotator cuff repair, instability surgery and shoulder replacement.
I perform surgery of the foot and ankle. I do not perform spinal surgery.
I have visited Tonga on an annual basis for the past 24 years, performing voluntary surgery for children with clubfeet.
