Osteoarthritis is a common joint disease that leads to problems such as pain, restricted mobility, and decreased quality of life in the knee joint, especially among elderly individuals. In advanced-stage knee osteoarthritis, total knee arthroplasty (TKA) is performed to reduce pain and loss of function. However, in the postoperative period, patients may encounter various problems such as pain, sleep disturbances, anxiety, and difficulties in daily living activities.

This study investigates how continuous care counseling based on Roy's Adaptation Model affects the comfort and quality of life of patients undergoing total knee arthroplasty. Roy's Adaptation Model is a widely used approach in nursing that supports individuals in adapting to changes they experience. Counseling and education provided in line with this model aim to help patients cope with the physical and psychological problems they face before and after surgery.

In the study, specially designed training and counseling services were offered to patients who underwent surgery, and the effects of these services on pain, anxiety, sleep quality, and daily living activities were evaluated. The results of the research indicate that continuous care counseling based on Roy's Adaptation Model may be effective in improving patients' postoperative comfort and quality of life. These findings may contribute to the improvement of postoperative care for both patients and healthcare professionals.

Osteoarthritis is a chronic joint disease that affects millions of people worldwide and is particularly prevalent among the elderly population. Knee osteoarthritis leads to significant problems such as severe pain, restricted mobility, and loss of independence, thereby negatively impacting quality of life. In advanced stages of knee osteoarthritis, total knee arthroplasty (TKA) is a commonly preferred surgical method to reduce pain and loss of function. However, in the postoperative period following TKA, patients may experience multidimensional problems such as pain, sleep disturbances, psychological stress, anxiety, and difficulties in daily living activities.

In modern nursing practice, the management of these problems experienced by patients before and after surgery and the improvement of their quality of life are of great importance. Roy's Adaptation Model is a theoretical framework frequently utilized in nursing that supports individuals in adapting to environmental changes and stressors. This model advocates for a holistic assessment of patients in terms of their physiological, psychological, social, and role functions, and for the structuring of care plans accordingly.

This study aims to evaluate the effect of continuous care counseling based on Roy's Adaptation Model on the comfort and quality of life of patients undergoing total knee arthroplasty. In the research, specially designed training and counseling services were provided to patients who underwent surgery, and the effects of these services on pain, anxiety, sleep quality, and daily living activities were evaluated using both quantitative and qualitative methods. Within the scope of the study, patients in the intervention group received continuous care counseling and video-supported education based on the Roy Adaptation Model, while the control group received standard care. Data were collected and analyzed using quality of life and comfort scales.

The findings of the study indicate that continuous care counseling based on Roy's Adaptation Model may be effective in improving postoperative comfort and quality of life in patients undergoing total knee arthroplasty. These results may contribute to the improvement of postoperative care and the development of patient-centered care practices for both patients and healthcare professionals.
