In line with the relevant physician's protocol, Quadriceps Isometric Exercises, Passive ROM exercises, active hip exercises while wearing a brace, ankle exercises, and ice application training are given. The patient is asked to continue as a home program for 2 weeks. After 2 weeks, electrical stimulation (15-20 minutes), current exercises, and ice application continue in the unit. (15min). A total of 30 sessions are applied. In addition, it is requested that the exercises be done at home, as in the treatment program (3x10).

Motor imagery training will be planned according to the PETTLEP model. A quiet environment will be provided to minimize distractions during the motor imagery session, and the patient's eyes will be closed throughout the session. At the very beginning of the session, a relaxation exercise lasting approximately 2 minutes will be performed to maximize attention during motor imagery. In relaxation exercises, patients will be asked to focus on their breathing, become aware of each body area, and relax the muscles in these areas. Care will be taken to ensure that the imagined movement is of similar duration to the real and optimal movement. Motor imagery will mostly be studied from a first-person perspective. During kinesthetic imagery, people will be asked to feel the movement of their body parts during each exercise without any body movement occurring. 3 sessions per week will last for 6 weeks in total.

Conventional Physiotherapy

Tampa Kinesiophobia Scale: This scale, consisting of 17 questions, evaluates the person's avoidance of movement or fear of re-injury. A Likert-type scale consisting of 4 points is used. 1 point means 'I disagree', and 4 points means 'I agree'. The individual receives a total score between 17 and 68 on this scale. A high score means high kinesiophobia.

Tegner Activity Scale: Although the scale consists of 11 questions in total, the difficulty level increases as you go from 0 to 10. While 0 means that he is either resting or retired due to his knee problem, 10 means that he is at a level where he can play competitive football at the national and elite levels. The individual is asked to mark the most appropriate one among these 11 items according to his activity level.

IKDC (International Knee Documentation Committee): The IKDC is a purely subjective assessment that assigns patients a functional overall rating. Three categories are examined by the questionnaire: symptoms, athletic activity, and knee function. The symptoms subscale aids in evaluating issues like pain, stiffness, edema, and knee giving way. The stair climbing, standing up from a chair, squatting, and jumping functions are the emphasis of the sports activity subscale. Higher scores indicate higher levels of function and lower levels of symptoms, with the transformed score being regarded as a measure of function.
