The goal of this clinical trial] is to investigate the effects of virtual reality (VR) in patients undergoing total knee arthroplasty (TKA). The main questions it aims to answer are:
All the patients included in the study were informed about the disease, the goals of post-surgical rehabilitation, the conditions to be considered after TKA and exercises. Sitting on the side of the bed and mobilization in or out of the room with a walker were provided with the postoperative 1st day exercises. The patients were discharged 2.5 days after surgery. The patients in both groups were taught an exercise program for home practice.
In addition to the exercise program, the virtual reality application was applied before the exercises to the VR group. The second evaluation was made 3 days after the end of the treatment in both patient groups.
Researchers compared VR and exercise to see if pain, kinesiophobia, pain catastrophizing, knee range of motion, function, and quality of life had changed.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| VR Group | Experimental | The patients in the VR group were informed about the disease, the goals of post-surgical rehabilitation, the exercises, and the circumstances to be considered following TKA. On the postoperative first day, activities included sitting on the side of the bed and mobilizing in and out of the room using a walker. Patients were discharged 2.5 days after surgery. Patients were provided an exercise program for at-home practice. In addition to the exercise program, VR glasses were used before the exercises in the VR group. The second examination was performed three days after the completion of treatment. |

| Exercise Group | Active Comparator | Exercise group were informed about the disease, the goals of post-surgical rehabilitation, the exercises, and the circumstances to be considered following TKA. On the postoperative first day, activities included sitting on the side of the bed and mobilizing in and out of the room using a walker. Patients were discharged 2.5 days after surgery.

| virtual reality application | Device | VR was used for 10 minutes a day in the sitting position for three weeks, twice a week, by watching a walking video before beginning the exercises. Patients were instructed to imagine themselves walking while concentrating on walking and watching the video. The patients were asked to stop watching video by removing their VR glass if they experienced discomfort such as dizziness and nausea during the VR application. They were told to continue watching the video when the discomfort was gone. In cases where similar discomforts recurred, the treatment was terminated. |

| Kinesiophobia assessed by Tampa Kinesiophobia Scale | Kinesiophobia was evaluated by using the Tampa Kinesiophobia Scale (total score between 17-68) (higher values indicate higher kinesiophobia). The Tampa Kinesiophobia Scale includes the parameters of injury/re-injury and fear of movement; scores of 37 and above indicate the presence of high kinesiophobia (ICC: 0,806). | first day after TKA |

Inclusion Criteria:
Exclusion Criteria:
It has been determined that women's proportion of knee extensors, knee flexors and knee Flexors / extensors ratio when compared with men, the ratio of the knee extender and flexor muscle groups is different in relation to the overall body muscle mass, and there are differences in functional outcomes in women and men in the early post-TKA period. It is also believed that women have more pain sensitivity than men and that pain inhibition mechanisms are less effective. Only female patients were included in this study because differences between groups and within-groups could not affect the results of the study.

The intensity of pain was evaluated by using the Numerical Pain Rating Scale (score between 0-10) (higher values indicate higher pain) at rest, at night and during functional tests (ICC: 0,84). |
| 4th week after TKA |
| pain catastrophizing assessed by Pain Catastrophizing Scale | Pain catastrophizing was evaluated by using the Pain Catastrophizing Scale (total score between 0-52) (higher values indicate higher pain catastrophizing). The scores of 30 and above taken from the Pain Catastrophizing Scale indicate the presence of high pain catastrophizing (ICC: 0,83). | first day after TKA |

| knee range of motion assessed by universal goniometer | ROM was measured with a universal goniometer. Active flexion and extension measurements were performed while the patients were lying in the supine position (ICC: 0.81; ICC: 0.86, respectively). In the knee extension evaluation, cases where 0° could not be reached in the evaluation of knee extension were recorded as positive values, and the degrees of knee extension performed more than the initial position of 0° were recorded as negative values. | first day after TKA |

| objective functional measurement assessed by functional tests | For the Five Times Sit to Stand Test (time-second), subjects were asked to rise from a standard height (43 cm) chair without armrests, five times, as fast as possible with their arms folded (ICC: 0.80). For the Timed Up and Go Test (time-second), subjects were asked to rise from sitting in an armchair, walk 3 meters, turn, walk back to the chair, then sit down and a walking aid if required (ICC: 0.97). For the Stair Climb Test (time-second), subjects were asked to ascend steps at the bottom of eight steps (15 cm high, 27.5 cm deep). Subjects could use the handrail if preferred and a walking aid if they normally used one. After a brief rest, the subject was asked to descend the stairs (ICC: 0.93). | first day after TKA |

| subjective functional measurement assessed by Western Ontario and McMaster Universities Osteoarthritis Index | The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) (total score between 0-96) (higher values indicate worse function) is a disease-specific, self-administered questionnaire developed to study patients with hip or knee OA. It consists of 24 questions, grouped into 3 subscales (pain, stiffness, and physical function). In Likert scale, there are five alternative answers to every question (0=none, 1=mild, 2=moderate, 3=severe, 4=extreme). The maximum score in Likert scale scale is 20 points for pain, 8 points for stiffness, and 68 points for physical function (ICC: 0.71-0.94). | first day after TKA |

| quality of life assessed by Short Form 36 | Quality of life was evaluated using the Short Form 36 (SF-36) quality of life scale (total score between 0-100 for each subscale) (higher values indicate better health). SF-36 consists of a total of 36 items belonging to 8 different subgroups called physical, social, emotional function, physical role, mental health, fatigue, pain, and general health. An increase in the score indicates better health, while a decrease indicates worse health (Cronbach's Alpha: 0.7324-0.7612). | first day after TKA |
