Brief summary
The purpose of this study is to translate and culturally adapt the subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) into Turkish, and to determine the measurement properties of the Turkish version.
Detailed description
Patellofemoral pain and patellofemoral osteoarthritis are highly prevalent knee disorders associated with pain and functional limitations. Patient-reported outcome measures (PROMs) are suggested for clinical and research use; however, there is a lack of objective disease-specific PROMs for patellofemoral pain and osteoarthritis. The purpose of this study is to translate and culturally adapt the subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) into Turkish, and to determine the measurement properties of the Turkish version.

| Measure | Time frame | Description |
|---|---|---|
| the subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) | first day | The subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF) is a disease-specific PROM designed to evaluate pain, stiffness, and quality of life in patients with patellofemoral pain and/or osteoarthritis. It has 11 items that assess three domains: stiffness (1 item), pain (9 items), and quality of life (1 item). Each item consists of five response options with a score between 0 and 4. The total score ranges from 0 (worst) to 100 (best). |
| the Kujala's Anterior Pain Scale (AKPS) | first day | The Kujala's Anterior Pain Scale (AKPS) is a self-administered questionnaire designed for patellofemoral disorders. It consists of 13 items on symptoms and functional limitations. The total score ranges from 0 to 100, with higher values indicating less functional status |
| the Short Form-36 health survey (SF-36) | first day | The short-form 36 (SF-36) health survey is a tool for assessing general health-related quality of life. It consists of 36 questions divided into eight domains, which are then merged under two large headings: physical component summary and mental component summary. The total score varies between 0 and 100. Higher ratings indicate a better quality of life. |
| the global rating of change (GROC) | 3 months after | The global rating of change (GROC) score is a single-item questionnaire with five potential responses depending on the patient's change in knee pain following the initial assessment. Likert scale with five response options: 0 points (much worse), 1 points (slightly worse), 2 points (about the same), 3 points (slightly better), and 4 points (much better). |
