Research summary
Surgery to replace the knee joint is known as a total knee replacement. This surgery is usually performed for people who have painful arthritis of the knee joint when other forms of treatment such as painkillers, physiotherapy or weight loss has failed to alleviate symptoms. Total knee replacement is usually very successful but few patients feel that their knee is normal after this surgery and up to 20% of patients may feel dissatisfied with the surgery. We do not know why this is the case but one theory is that a knee replacement doesn’t move in the same way as a natural knee. In order to try and improve patient’s function and satisfaction after total knee replacement Smith and Nephew™ have developed a design of knee that aims to reproduce more normal knee movement and potentially better function. This knee is called the Journey BCS II. Its design has been extensively tested in computer simulation but has not been fully evaluated after it has been put into patients. The aim of our study is to use a scientific assessment of gait to look at how patients walk and move after implantation of this knee compared with a more traditional type of knee called the NexGen™ (Zimmer). The study will match patients who have had one or the other type of total knee replacement so that the comparison is between patients of similar ages and sex and then use a scientific technique called gait analysis to assess walking ability. The scientist performing and interpreting the gait will not know which knee each patient has. By performing this study we hope to prove that this new design of knee works as well in clinical practice as in computer simulation.
