RESUMEN
Background: Knee osteoarthritis is the most prevalent type of osteoarthritis. Patients frequently encounter pain triggered by movement that evolves into impaired joint function. Needing persistent rest or having night-time pain signifies advanced disease. Qualitative research is considered the most effective method for comprehending patients' needs and contexts. Methods: This study employed a qualitative research design, allowing the researchers to acquire insights into the patients' beliefs and values, and the contextual factors influencing the formation and expression of these beliefs and values. Results: A cohort of nine patients awaiting total knee replacement (TKR) surgery was included and they were interviewed until data saturation was achieved. The results of the phenomenological analysis resulted in the identification of three themes: "The existence of pain impedes the capacity to participate in daily life activities"; "TKR induced fears and uncertainties regarding the progression of the disease"; "Severe nighttime pain compromising sleep quality". Conclusions: This study analyzes the experiences of people awaiting TKR surgery, emphasizing the importance of addressing their unique needs to improve preoperative education and rehabilitation. In this way, patients' recovery during the postoperative phase can be improved.
