The WOMAC LK 3.1 questionnaire is a validated tool commonly used for assessing knee pain, stiffness, and function. The WOMAC LK 3.1 questionnaire has 24 items that the patient addresses about the knee: 5 items on the pain subscale, 2 on the stiffness subscale, and 17 on the physical function subscale. Each item is answered on a 5-point Likert scale, with grading from 0 (none or never) to 4 (extreme or always). A higher score indicates worse pain, stiffness, or functional limitation.

The WOMAC Stiffness subscale consisted of two questions scored from 0 to 4. The Stiffness has a range of 0(no stiffness) to 8 (maximal stiffness)

The WOMAC Physical Functioning subscale consisted of seventeen questions scored from 0 to 4. The Physical Functioning has a range of 0 (no functional limitation) to 68 (maximal functional limitation)

The KOOS questionnaire is a commonly used instrument to assess the patient's opinion about their knee and associated problems. KOOS consists of 5 subscales: Pain (9 questions), Symptoms (7 questions), Function in daily living (ADL) (17 questions), Function in sport and recreation (Sport/Rec) (5 questions) and knee related Quality of Life (QOL) (4 questions). The previous week is used as the time period for answering the questions.

A higher score on the KOOS questionnaire indicates no problems, and 0 indicates extreme problems. Each subscale score is calculated independently. The mean score of the individual items of each subscale is calculated and divided by 4 (the highest possible score for a single answer option). on). Traditionally in orthopedics, 100 indicates no problems and 0 indicates extreme problems. The normalized score is transformed to meet this standard.

The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. Eight subscales of the Short Form-36 questionnaire are used to derive Physical Component and Mental Component measures

The Visual Analogue Scale is a common tool for measuring general pain. A 100 mm line is marked from 0 to 10 in 10 mm increments. Knee pain severity is indicated by drawing a vertical mark at the point on the line that best represents the severity of pain. No pain is indicated by the 0 at the far left, and the worst possible pain is indicated by the 100 at the far right.
