Background/aim: Knee osteoarthritis (OA) is a common pathology characterized by degeneration of the articular cartilage. The aim of the research was to ask patients how they decided to make the injection, what treatments they received, their complaints prior to and after the injection and how they feel at the moment, and whether they are currently exercising or not. Thus, to demonstrate the patients & rsquo; outcomes with their own expression. Materials and methods: A total of 92 knee OA patients completed semistructured interviews, which included six open-ended questions. Results: A total of 92 patients (66 female, 26 male) aged between 36 and 95 years (mean 65.511.14) were included. Before the injection, the majority of the OA patients had pain complaints when walking (72.8%) and stair climbing (70.7%). One to four years after intraarticular injection, 45.2% of patients felt a decrease in their complaints. The majority of patients did not consider diet and exercise as a treatment option. In addition, almost all patients declared that they decided on hyaluronic acid injection treatment with the physician & rsquo;s recommendation. Conclusion: Pain during walking and stair climbing before hyaluronic acid injection was common in knee OA patients. Overall the patients felt a decrease in the symptoms after injection. Patients did not consider diet and exercise as a treatment option despite the recommendation by a physician.
