Outcome Measures
Primary Outcomes (6)
the subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF)
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).
first day
the Kujala's Anterior Pain Scale (AKPS)
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
first day
the Short Form-36 health survey (SF-36)
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.
first day
the subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF)
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 subscale of the Knee Injury and Osteoarthritis Outcome Score for patellofemoral pain and osteoarthritis (KOOS-PF)
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).
3 months after
the global rating of change (GROC)
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).

Eligibility Criteria
Patients with patellofemoral pain and OA
You may qualify if:
- 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)
You may not qualify if:
- 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
