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.

Eligibility criteria: Inclusion Criteria:

* peripatellar or retropatellar knee pain persisting for at least 3 months and exacerbated by activities that load the patellofemoral joint;
* pain intensity of at least 3 mm according to the visual analogue scale (VAS)

Exclusion Criteria:

* diffuse or generalized knee pain
* severe trauma to the target knee in the previous year
* moderate to severe concomitant tibiofemoral osteoarthritis
* recent knee injection (within 3 months)
* systemic inflammatory conditions
