About this study
The aim of this qualitative interview study is to gain new and in-depth knowledge about patients' experiences of information following total knee arthroplasty. Participants will be interviewed in the recovery phase after surgery. Researchers will use a semi-structured interview guide. The interviews will be analysed with qualitative content analysis.
Read the detailed description
A qualitative interview study will be conducted. Interviews will be conducted 24-28 weeks after total knee arthroplasty. A semi-structured interview guide will be used to answer the following research questions:
- What are the patients' positive and negative experiences of the information provided before and after total knee arthroplasty (TKA)?
- What are the patients' experiences and perceptions regarding the content and scope of the information, as well as how and when it is communicated?
- What are the patients' experiences and perceptions of their access to information?
- What are the patients' experiences and perceptions of the significance of the information for postoperative care and their expectations of the surgical outcome?
- How do patients perceive the information provided before and after surgery in relation to their expectations of the information?
- How do patients think the information provided before and after TKA could be improved?

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Interview group | To ensure variation in the sample, diversity in age and sociodemographic background is sought. Inclusion criteria: Men and women of all ages who have undergone total knee arthroplasty due to osteoarthritis and are undergoing rehabilitation in primary care. Exclusion criteria: Previous joint replacement in the hip or knee. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Qualitative content analysis
The transcribed interviews will be analyzed in their entirety using qualitative content analysis, which includes interpretation of the manifest content of the text as well as a deeper interpretation of the underlying latent meaning. First, the transcripts will be read repeatedly to gain a sense of the whole. Then, meaning units that respond to the study's aim will be identified from the text, without being separated from their context. In the next step, these units will be condensed to shorten the text while preserving its core content. Based on the condensed meaning units, subcategories, categories, and themes will be formed by moving back and forth between the whole text and its parts. Potential subcategories, categories, and themes will be discussed within the research team until consensus is reached, in order to enhance the credibility of the analysis. The results will be presented as themes, categories, and/or subcategories.
Measured: Interviews will be performed 24-28 weeks after total knee arthroplasty
