Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will be consented to be included into the study. The patient will undergo total knee replacement surgery and receive a Saiph Total Knee Replacement which is a cemented implant that evolved from the successful Freeman-Samuelson principles. The operation will take approximately 1.5 hours and will be performed by the consultant orthopaedic surgeon with experience of implanting the Saiph Knee. The Saiph Knee is a TGA approved product and is used by many orthopaedic surgeons in Australia and New Zealand.



Intervention code [1] 294839 0
Treatment: Devices
Comparator / control treatment
The results will be compared to patient outcomes of the Saiph Knee when performed by the surgeon design team performed from November 2011 to December 2014. The control data was obtained in a clinical study, and the results will be published prior to the end of the current study. This study was performed under ethics approval at St Vincent's Hospital Sydney (Trial No 12/254) and The Avenue Hospital Melbourne (Trial No 144).
