Evaluating the impact of obesity on knee load over time in those who have undergone optimal surgical re-alignment after total knee replacement

Project Details

The study examines the impact of obesity on knee joint loading over time in those who have undergone optimal surgical re-alignment in total knee replacement (TKR). This study is important because (i) the number of TKR’s undertaken in Australia has doubled over the last decade with 40,000 procedures performed in 2010, (ii) obesity is emerging as an important risk factor which is over-represented (60%) in patients presenting for TKR, and (iii) 15-30% of patients express dissatisfaction or suboptimal improvement following TKR. Working with DePuy this study is the first of its kind, and will provide a greater understanding of the biomechanics of knee load during walking after TKR, the influence of obesity and how this affects TKR outcomes.
