Brief Summary:
In order to assess patients' concerns and other quality of life aspects, post-total knee arthroplasty (TKA) requires further assessment tools, more than controlled experiments testing defined isolated variables. Qualitative research offers useful methods to explicate the complexity and deeper meaning of patient experiences and outcomes post-TKA. Qualitative methods facilitate the collection of in-depth experiences and perceptions from individuals about a specific phenomenon which, in this case, is outcomes post-TKA. Specifically, a phenomenological approach allows for the collection of diverse and unique patient experiences and outcomes post-TKA .
The focus of this project is using focus groups to explore poorly understood areas, such as outcomes and experiences post-TKA, in order to generate useful findings and hypotheses.

Detailed Description:
Knee osteoarthritis (OA) is a major cause of disability around the world; it is the most common chronic condition in primary care in the UK. By 2030 it is predicted to be the greatest cause of disability in the general population . An effective end-stage treatment for knee OA is knee-replacement surgery, which was first done in the 1970s and 1980s.
In England and Wales, the number of knee-replacement procedures recorded by the National Joint Registry in 2013 was 91,703, which represents an increase of 0.9 % over 2012. The data analysis by the National Joint Registry and the Office of National Statistics suggests that, by 2030, primary Total Knee Arthroplasty (TKA) will increase by 117% from the 2012 level. Subsequently, TKA revision surgeries are expected to increase incrementally by 332%. There is a similar estimation of demand for revision TKA surgeries in the United States; by 2030, they are expected to rise by 601% from the 2005 level. The United States estimation of primary TKA is for growth of 673% from the 2005 level, which is similar to England and Wales's upper-limit projections .
Post-TKA, 75-85% of patients report satisfaction with surgery outcomes, while the remaining 15-25% are dissatisfied .Total knee arthroplasty's success has traditionally been evaluated from the surgeon's perspective, e.g. the presence of surgical complications or implant survival. This is gradually changing to involve the patient in measuring health outcomes and decision-making processes. Patient-reported outcome measures (PROMs) have evolved to explore patient perspectives by monitoring the quality of care in health organizations and conducting clinical trial outcomes.
More than half of patients' early concerns post-total knee arthroplasty (TKA) are not considered in commonly used patient-reported outcome measures . This may support current medical outcomes evaluation post-TKA having implications that differ from the patient perspective. This may be explained by the dissatisfaction of some patients post-TKA. So, being more sensitive to patient experience assessment methods is required, rather than profession-driven tools.
Patients' experiences and their perceptions of current outcome measurements post-TKA are poorly understood. In order to explore this area qualitative methods are appropriate, as they facilitate the collection of in-depth experiences and perceptions of individuals about a specific phenomenon which, in this case, is outcomes post TKA. Specifically, a phenomenological approach allows for the collection of diverse and unique patient experiences and outcomes post-TKA.
A focus group is useful for exploring poorly understood areas, such as outcomes and experiences post-TKA, in order to generate possible findings or hypotheses. It has advantages over one-to-one interviews as the interaction among group members provides an extra dimension to gather data and a wider degree of spontaneity in the patient views expressed, in contrast to one-to-one interviews where the interaction is limited to that between patients and researcher and depends on patient responses. Interaction in a group setting allows patients to refine their views in light of others' views and facilitates further spontaneous expression. Support for the feelings of other group members with similar experiences encourages less verbal individuals to contribute more than in one-to-one interviews.
Only three previous studies have used focus-group methods to explore patient experiences post-TKA. Studies by Westby et al. (2010) and Van Egmond et al. (2015) combined the results of patient experiences post-total knee arthroplasty and post-total hip arthroplasty, which does not support accuracy as those patient groups encounter different problems. The third study, by Zacharia et al. (2016), assessed outcomes at least three years post-TKA in a limited age range of 60-65 years for manual labourers of low and medium socioeconomic status. An appropriate well-structured methodology is required to explore patient experiences and outcomes post-TKA, with clear sampling and population criteria to facilitate the possible correlation of findings.
To the best of our knowledge, no study has explored patient experiences and outcomes post-TKA using focus-group discussions one year after surgery to explore whether there are factors that might help us to understand why some patient medical outcome measurements were good but they were not satisfied, or vice versa. Exploration of potential barriers to functional recovery may support future modifications that might improve outcomes post-TKA.
Project objectives
* To gain an in-depth understanding of experiences and perceptions of patients about outcomes post-TKA and to explore whether there are factors that might help us understand why some patients' medical outcome measurements were good but they were not satisfied, or vice versa.
* To gain insights into potential barriers to good functional recovery.
* To identify what modifications can be made to improve future outcomes post-TKA.
