Research proposal abstract:
The incidence of total knee arthroplasty is increasing and to keep up with the demand, there is a constant need of optimizing the quality of care. Recent innovations enable orthopaedic surgeons to use technological assistance during surgery. Technology assisted surgery (TAS) is registered in the LROI since 2022, and includes: Robot Assisted Surgery (RAS), patient specific instrumentation (PSI) and navigation. While navigation and PSI are passive forms of TAS, RAS fulfils a more active role during surgery by controlling or adjusting the surgeon’s movements during bone resection.
The latest innovations are promising, and lately there has been a rise in use of RAS, however whether these technical improvements have a significant clinical impact compared to conventional methods is still unclear.
This study on revision risk in technology assisted total knee arthroplasty (TKA) is an evaluation of early results, comparing RAS to conventional surgery, as well as comparing RAS to PSI and navigation. We will also compare outcomes of robots made by different manufacturers. As registration of TAS only started in 2022, we will be analysing LROI data from 2022-2024 to answer the research questions.
