Standard rehabilitation consisting of cold therapy, stretching and strengthening exercises will be applied. Treatment will be applied under the control of a physiotherapist 3 days a week and as home exercise 3 days a week.

A pressure algometer (digital algometer) will be used. It will be evaluated at four test sites at the knee (medial and lateral edge of the patella, lateral and medial femoral condyles) and one distal painless zone at the wrist extensors (5 cm distal to the lateral epicondyle).

It will be pressed with increasing pressure and the individual will be asked to say "yes" as soon as the participant feels pain or discomfort. Three attempts will be made at each point with a 30-second rest and the averages recorded.

It will be evaluated with the Central Sensitization Inventory. It consists of 2 parts, part A, which evaluates the symptoms thought to be associated with central sensitization syndromes, and part B, which quickly questions whether the patient has received a specific diagnosis before. In part A, there are 25 items that question the frequency of symptoms seen in central sensitization syndromes and are scored between 0-100 points. Each symptom is defined as "never" (0 points) if the patient never experiences that symptom, "rarely" (1 point) if rarely, "sometimes" if sometimes (2 points), "frequently" (3 points) if often It is recorded as "always" (4 points). As the patient's central sensitization inventory score increases, it is thought that he has more symptoms related to central sensitization. In part B, it is questioned whether the patient has ever been diagnosed with any of the diseases included in the central sensitization syndromes by any physician.

Active knee flexion and extension angle will be evaluated.

It will be measured during maximum voluntary isometric contraction using a hand-held muscle tester. After a warm-up test attempt, participants will be asked to extend their knees with maximum force against the device for five seconds. Two trials separated by a rest period of 120 seconds will be performed and averaged.

The Tampa Kinesiophobia Scale will be used. A 4-point Likert score (1=I totally disagree, 2=Agree, 3=Disagree, 4=Totally agree) is used for each question in the scale. As a result of the survey, the person gets a total score between 17-68. A high score on the scale indicates a high level of kinesiophobia.

The Timed Up and Go test will be used. While the patient is sitting in a chair; will be asked to get up from the chair, walk 3 meters as fast as possible, turn around and sit back in the chair. The time elapsed while the patient performs the test will be recorded.

Timed Get Up and Go test will be used. It compares the time between the actual movement time and the imagined similar task time. At the end of the tests, mental chronometer measurements are calculated in terms of delta time with the formula '(real movement-imagined movement)/[(real movement+imagined movement)/2]x100'.

It is a questionnaire that evaluates the imagery of four movements consisting of knee bending, jumping, arm movement and bending. It consists of three subscales and a total of 12 items evaluating external visual imagery, internal visual imagery, and kinesthetic imagery. Before starting the questionnaire, participants are given definitions of external visual imagery, internal visual imagery, and kinesthetic imagery. Before scoring each movement, the person is asked to perform the movement, then the movement is visualized three times. It is scored on a scale from 1 to 7. 1 point means "very difficult to see/feel", while 7 points means "very easy to see/feel".
