Introduction
Total knee replacement is a cost effective treatment for end-stage osteoarthritis of the knee and the rate of this procedure continues to increase, which is thought to be due to an aging society with greater functional demands. The outcome of total knee replacement is variable, however, with approximately one in five patients not being satisfied with their knee after surgery. There are multiple patient factors that are thought to affect the outcome of total knee replacement. The aim is to review the published literature and present the current evidence regarding the influence of patient factors upon the outcome of total knee replacement.
Conclusion
A patient’s outcome according to the Oxford knee score is not influenced by their age, socioeconomic status and mental wellbeing, but is influenced by fulfilment of their pre-operative expectations and their post-operative general physical health. In contrast to the Oxford knee score the rate of patient satisfaction is influenced by socioeconomic status, mental wellbeing, in addition to fulfilment of expectations and the post-operative general physical health of the patient.
