Orthopaedics research at Murdoch
Our orthopaedic research led by Professor Allan Wang, Professor Piers Yates, Mr Ben Jeffcote and Mr Mark Hurworth focuses on improving outcomes for patients. Research concentrates on rehabilitation and investigating if new technology improves patient outcomes after knee, hip and shoulder surgery.
Our research is undertaken at the Murdoch Centre for Orthopaedic Research 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.
- Radiological and clinical outcomes of joint replacement and knee cartilage repair surgery.
- Computer navigation and clinical outcomes in shoulder replacement surgery.
Computer navigation of reverse total shoulder arthroplasty: the learning curve
The aim of this project is to explore the application of computer navigation in reverse total shoulder arthroplasty (RSA) and to determine its learning curve, safety and accuracy.
The knee stress test: a proposed test for assessing patient outcomes in knee arthroplasty using a bicycle power meter
This study examines a new method to test muscle power using a bicycle power meter. The first phase of the study examines the reliability of this new test in healthy control participants. The second phase of the study involves assessing the post-operative recovery of participants undergoing a total knee replacement (TKR). Participants will be followed for one year to assess the recovery of their leg muscle power and function.
Patient satisfaction following plantar fasciotomy
With the efficacy of surgical treatment for plantar fasciitis not established, it is important to determine its success through long-term patient reported outcome and satisfaction levels following surgery. The aim of this study was to investigate patient satisfaction and quality of life following plantar fasciotomy.
Clinical and radiological outcomes using the Absolut femoral prosthesis and the Global cup system
This study evaluates post-operative radiology and clinical outcomes in patients who undergo primary total hip replacement using the Absolut femoral stem and Global acetabular cup. Patients will be recruited over a two year period and followed up to 10 years after surgery.
Multi-Center Clinical Evaluation of the ATTUNE® Revision System in the Revision Total Knee Arthroplasty
Five-year, prospective, multi-center, non-randomized, non-controlled study of the ATTUNER Revision total knee prostheses, utilizing the fixed bearing (FB) and rotating platform (RP) tibial component with the posterior stabilizing (PS) femoral component in revision total knee arthroplasty (TKA).
Multi-Center Clinical Evaluation of the ATTUNE® Revision System in Complex Primary Total Knee Arthroplasty
Five-year, prospective, multi-center, non-randomized, non-controlled study of the ATTUNER Revision total knee prostheses, utilizing the fixed bearing (FB) and rotating platform (RP) tibial component with the posterior stabilizing (PS) femoral component in complex primary total knee arthroplasty (TKA).
Cartilage repair registry
The purpose of the cartilage repair registry is to improve and maintain the quality of care for individuals receiving cartilage repair surgery. The aim is to capture data on all patients undergoing cartilage repair surgery to objectively determine their functional outcomes using condition specific patient-reported outcome measures.
A comparison of functional outcomes at baseline and three months post knee arthroscopy: a pilot study
Arthroscopy is an important and commonly performed orthopaedic procedure in Australia and considered the gold standard in the diagnosis of meniscal and ligamentous injury. Large numbers of arthroscopies are performed at St John of God Murdoch Hospital yet no evaluation of patient reported functional outcomes has been undertaken. This study aimed to document patient self-reported functional outcomes at three months post arthroscopy using a validated tool and demonstrate feasibility of undertaking these post-operative evaluations.
Partial versus total knee replacement: a single surgeon retrospective study
This study aimed to investigate differences between total knee replacement (TKR) and partial knee replacement in today’s technological setting.
