Measured by the Symptoms Knee injury and osteoarthritis score subscales (KOOS subscales). The KOOS survey is comprised of 42 questions. The questions are divided into 5 sub-categories: symptoms (7 questions), pain (9 questions), function/daily living (17 questions), function/sports and recreational activities (5 questions), and quality of life (4 questions). The total range for each sub-category is 0-100, making the total range for the whole survey 0-500. The higher the score, the worse the symptoms and pain/ higher difficulty in function.

VAS is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 100 mm horizontal line, and this rating is then measured from the left edge (=VAS score). The total score range is 0 (no pain) to 10 (worst pain imaginable); the higher the score, the worse the pain.

AROM is measured using a goniometer (protractor that measures joint angles) to see how much the knee can bend and straighten on its own (without assistance). Normal ROM at the knee is considered to be 0 degrees of extension (completely straight knee joint) to 135 degrees of flexion (fully bent knee joint).

The ACL-RSI scale includes 12 questions on the patient's emotional well-being and confidence in his or her performance and risk appraisal. The scale, with scores ranging from 1 to 10, includes 5 questions on emotional well-being, 5 questions on confidence in physical performance, and 2 questions on the appraisal of risk. Higher scores indicate a more positive psychological response. The total score is determined by adding the values of the 12 responses and then calculating their relationship to 100 to obtain a percentage (0-100%).
