Orthopaedics research at Murdoch

Our orthopaedic research led by Professor Piers Yates focuses on the use of pain relief and other medications in knee replacement patients. Research concentrates on ensuring medication is used for optimal results while also investigating if new technology improves patient outcomes after knee replacement surgery.

Our research is undertaken at St John of God Murdoch Hospital – one of the leading private hospitals providing orthopaedic care in Western Australia.

  • Knee replacement surgery is a common orthopaedic procedure, with about 50,000 total knee replacements occurring in Australia last year. This number is rising each year in line with our ageing population.
  • Orthopaedic research is particularly important as there is an increasing number of technologies and equipment available in this field. Therefore assessing patient outcomes (including recovery times, mobility, complications and time spent in hospital) ensures this technology is used effectively.
  • Furthermore, medication to assist recovery and care is important for patients undergoing knee and hip replacements. Optimal use of medication ensures patients have reduced pain levels and improved mobility after surgery.
  • Our research focuses on assessing how medications work for patients undergoing knee replacement surgery and the most effective options to reduce pain and provide optimum results.
  • We are also investigating, as a part of a broader study, how new and emerging knee replacement technology effects patient outcomes.
We have three clinical trials underway and are currently recruiting participants.
