Research Projects and Pioneering Techniques

  • Development of a patient outcomes measure to assess the results of hip and knee replacement in highly functioning young patients. The resulting HAAS (High Activity Arthroplasty Score) has been translated into four languages.
  • Improvement of the accuracy of positioning of knee replacements. Identified an error in the prior techniques for judging the rotational position of the femoral component of knee replacements. Developed Sulcus Line technique for measuring the position more accurately during surgery. The associated device has been patented and is in production ( This has led to multiple publications and presentations and improved the accuracy of surgeons performing knee replacement.
  • Currently assessing the clinical results from a large trial using a new generation of knee replacements known as medial pivot knees. The results are showing improved knee stability compared to previous designs and higher rates of patient satisfaction.
  • Total knee replacement instrument design and assessment. Provided surgeon consultation to Advanced Surgical Design and Manufacture (ASDM, Sydney) in production of a completely new instrument set for the Active knee replacement.
