Brief summary

Primary total hip arthroplasty (THA) is an increasingly common procedure with 400331 procedures in Australia during 2016. This is 94.4% higher than the numbers undertaken in 2003. Literature suggests a revision rates ranging from 4% to 33% in this young population compared to 7%-15% for older patients. Loss of bone stock during primary THA may adversely affect subsequent revision THA. The purpose of this study was to compare preservation of acetabular bone stock between conventional THA and Hip resurfacing vs. robotic MAKO THA. We hypothesize that the robotic system would allow more precise reaming, leading to greater preservation of bone stock.

Interventions

Patient will undergo robotic total hip replacement as per normal practice. No additional intervention will take place. This is typically 60-90min procedure. The bone reamings will be collected and the dry weight will be measured after the patient has left the theatre.
