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: * Does VR have effects on pain, kinesiophobia, and function during the early rehabilitation period of patients who have undergone TKA * Does VR contribute to the success of exercise treatment after TKA 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.

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.
activities included sitting on the side of the bed and mobilizing in and out of the room using a walker. Patients were provided an exercise program for at-home practice.

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).
Time frame: first day after TKA

knee pain assessed by Numerical Pain Rating Scale
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).

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).

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.

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).

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).

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).
